Tyre processing line integration is the difference between a baler working at 60% capacity and one running at full output. The bottleneck in most operations isn’t the machine’s compression speed; it’s everything that happens between processing stages.
A mechanically connected line removes those gaps. A sidewall cutter feeds directly onto a conveyor, the conveyor feeds the baler, and the entire system runs as one continuous process. The same operator, the same baler, and throughput that’s 50% to 70% higher.
Standalone equipment forces operators to handle material between processing stages. A tyre baler operating alone requires operators to manually carry tyres from storage, position them in the loading chamber, and repeat this 80 to 90 times per bale. That manual handling consumes 40% to 60% of total cycle time.
Integrated processing lines eliminate inter-stage material handling by mechanically connecting equipment. A sidewall cutter feeds cut tyres onto a conveyor, which delivers them directly to the baler’s loading chamber. The operator loads the cutter at one end; finished bales emerge at the other end. No walking between machines. No manual carrying of tyres.
This integration typically improves throughput by 50% to 70%. A standalone MKII processes 80 tyres per hour. The same baler integrated with cutter and conveyor processes 120 to 140 tyres per hour with the same operator labour. The equipment hasn’t changed; the workflow has.
The bottleneck in tyre processing is rarely the baler’s compression speed. It’s the time operators spend moving tyres around the facility. Integration eliminates that bottleneck.
Gradeall International manufactures integrated tyre processing equipment at our facility in Dungannon, Northern Ireland. We’ve designed and installed complete processing lines across 100+ countries over nearly 40 years, and the throughput improvements are consistent and measurable.
A complete integrated tyre processing line comprises three primary machines and supporting infrastructure.
Truck tyre sidewall cutters remove rigid sidewall sections that resist compression. This improves bale density by 15% to 25% and reduces compression cycle time.
Types:
Output: Cut tyres (sidewalls removed, tread section remains) that compress more readily than whole tyres.
Cycle time: 30-60 seconds per tyre, depending on size.
Inclined tyre baler conveyors transport tyres from ground level to the baler’s elevated loading chamber. This eliminates manual lifting and carrying.
Specifications:
The conveyor elevates tyres approximately 2 to 3 metres vertically, which aligns with the baler’s loading door height.
Tyre Baler
The MKII tyre baler forms the core of the system. It receives tyres from the conveyor and compresses them into 900kg bales.
Key integration features:
Buffer zones: Staging areas between equipment allow operators to accumulate tyres during equipment downtime (maintenance, wire changes, etc.). Typically, 5 to 10 square metres near the cutter output.
Control stations: Operator panels at strategic points (cutter, baler) with visual line-of-sight to all equipment. Emergency stops are accessible from any operator position.
Material flow paths: Clearly marked routes for forklift access, finished bale removal, and personnel movement. Integration shouldn’t create safety hazards from crossing paths.
Pre-processing tyres before baling delivers measurable benefits, but only if the material flow from the cutter to the baler is efficient.
The cutter should be positioned 6 to 12 metres upstream of the baler. This allows space for:
Positioning the cutter too close (under 4 metres) creates congestion. Positioning too far (over 15 metres) requires longer conveyors, which add cost and reduce efficiency.
Pattern A: Continuous feed (ideal):
This pattern requires two operators: one at the cutter, one at the baler. Throughput: 120-150 tyres per hour.
Pattern B: Batch processing (single operator):
This pattern uses one operator moving between stations. Throughput: 90-110 tyres per hour (lower than continuous but still 15-30% better than standalone baling).
Density improvements:
Cutting sidewalls before baling improves compression:
Denser bales mean fewer bales per thousand tyres, which reduces transport frequency and improves end-user pricing (higher-density bales command premiums).
The inclined conveyor is the mechanical link connecting upstream and downstream equipment. Design considerations affect reliability and throughput.
Heavy-duty rubber belting (10-12mm thickness) withstands tyre loads and continuous operation. Standard conveyor belting (6-8mm) used for lighter materials fails prematurely under tyre loading.
Cleats: Horizontal ridges (50-80mm height) welded across the belt at 400-600mm intervals prevent tyres rolling backwards down the incline. Without cleats, tyres slip whenthe belt speed varies or stops.
Width: 800-1,000mm belt width accommodates car tyres (600-800mm diameter) without overhang. Narrower belts (600-700mm) work for car tyres only; wider belts (1,200mm+) handle truck tyres.
Electric motor: 1.5-2.2kW is sufficient for tyre conveyors. A variable frequency drive (VFD) allows speed adjustment based on baler loading rate.
Gearbox: 20:1 to 40:1 reduction ratio delivers required belt speed (0.3-0.5 m/s) with adequate torque for loaded operation.
Chain or belt drive: Chain drive (more common) handles shock loads better. Belt drive is quieter but requires more frequent tension adjustment.
Elevation gain: 2.0-3.0 metres typical (ground level to baler loading door) Horizontal run: 5-7 metres (results in 30-40 degree incline) Steeper angles (over 45 degrees) cause tyres to tumble or jam on the belt. Shallower angles (under 25 degrees) require longer conveyors, increasing cost and footprint.
Input end: Operator places tyres onto the moving belt at ground level. Some systems include a short horizontal feed section (1-2 metres) to allow easier tyre placement.
Discharge end: Belt terminates at baler loading door. Tyres tip off the belt end directly into the loading chamber. Adjustable discharge chute directs tyres to optimal chamber position.
Capacity:
Conveyor capacity should exceed baler consumption rate to prevent bottlenecks. If the baler processes 80 tyres per hour, the conveyor should reliably transport 90-100 tyres per hour.
Typical conveyor cycle: 20-30 seconds per tyre (belt speed and incline dependent). Theoretical capacity: 120-180 tyres per hour. Actual capacity accounting for loading delays: 90-110 tyres per hour.
Physical layout affects workflow efficiency, safety, and operator productivity.
Equipment arranged in a straight line: [Cutter] → [Buffer] → [Conveyor] → [Baler] → [Bale staging]
Total length: 15-18 metres Width: 6-8 metres (including access aisles) Total footprint: 90-144 square metres
Advantages: Simple material flow, easy to visualise, straightforward installation. Disadvantages: Requires long, unobstructed space
Best for: Greenfield installations, warehouses with long clear spans
Cutter and baler positioned ata 90-degree angle with the conveyor,r making the turn:
[Cutter] → [Buffer]
↓
[Conveyor]
[Baler] → [Bale staging]
Total dimensions: 12m × 10m Footprint: 120 square metres
Advantages: Fits rectangular spaces better, separates loading and unloading areas. Disadvantages: Requires a cornering conveyor (more complex, higher cost by £1,500-£2,500)
Best for: Existing facilities with space constraints, L-shaped warehouse areas
Equipment positioned so the operator can supervise all machines from a central location:
[Bale staging] ← [Baler]
↑
Footprint: 10m × 12m = 120 square metres
Advantages: The operator at the centre can monitor all equipment, with minimal walking between stations. Disadvantages: Requires the most complex conveyor routing
Best for: Single-operator operations prioritising efficiency
Regardless of layout, plan for:
Integration changes how operators work. Task allocation and training determine whether throughput gains are realised.
Single-operator integrated workflow:
One operator manages the entire line by working in batches:
Phase 1: Cutting (20 minutes)
Phase 2: Baling (20 minutes)
Phase 3: Repeat
Throughput: 90-110 tyres per hour (versus 80 tyres per hour standalone baling). The 15-35% improvement comes from pre-cutting (faster compression) and reduced inter-stage walking.
Two-operator integrated workflow:
Operator 1: Cutter station (continuous loading) Operator 2: Baler station (supervising automatic feed from conveyor)
Throughput: 120-150 tyres per hour. Both machines run continuously with no idle time.
Labour cost: Double (two wages), but throughput increases 50-85% vs single-operator standalone baling. Cost per tyre processed drops by 15-25% despite additional labour.
Training for integrated systems:
Operators need cross-training on all equipment:
Training time: 8 hours per operator (versus 4 hours for standalone equipment). The additional 4 hours cover equipment interaction, sequencing, and troubleshooting multi-machine issues.
How equipment communicates affects safety and efficiency.
Each machine has independent controls. OThe operatorstarts the cutter, then conveyor, then baler manually. No automatic coordination.
Advantages: Simple, reliable, no complex programming. Disadvantages: Operator must rememberthe correct sequence, risk of starting equipment in the wrong order
Suitable for: Low-volume operations, simple installations
Emergency stops are electrically linked. Pressing any e-stop shuts down all equipment simultaneously. Start controls remain manual.
Advantages: Better safety (one e-stop halts everything), simple implementation. Disadvantages: Still requires manual sequencing
Suitable for: Most installations. Recommended minimum safety level.
A programmable logic controller coordinates all equipment. The operator presses the single start button; the PLC sequences the cutter, conveyor, and baler automatically. System monitors flow and adjusts speeds to prevent jams or overloading.
Advantages: Optimal efficiency, reduced operator workload, sophisticated fault detection. Disadvantages: Higher cost (£3,000-£5,000 additional for PLC integration), requires programming expertise for modifications.
Suitable for: High-volume operations (200+ tyres daily), facilities with multiple processing lines
Regardless of control sophistication, emergency stops must be integrated. Pressing any e-stop anywhere on the line immediately halts:
This prevents scenarios where tyres continue feeding into a stopped baler (jamming) or a running conveyor feeds into a stopped baler (creatinga safety hazard of unsupervised accumulation).
EN16500 safety standard requires integrated emergency stops for any mechanically linked equipment.
Quantifying integration benefits requires comparing actual processing times, not theoretical capacity.
Cycle breakdown for 1 bale (90 tyres):
Rate: 90 tyres ÷ 1.47 hours = 61 tyres per hour actual (versus 80 theoretical)
The gap between theoretical (80) and actual (61) exists because the theoretical assumes continuous operation with no wasted motion. Real operation includes walking, searching for tyres, and occasional equipment checks.
Rate: 90 tyres ÷ 0.72 hours = 125 tyres per hour actual
This isn’t theoretical; it’s measured data from customer installations. The improvement comes from:
Integration doubles annual capacity without doubling labour. Additional operator wages (£24,000 annually for the second operator) are offset by doubling revenue from processing fees or tyre sales.
Equipment costs must be justified by operational benefits.
Integration equipment costs:
Truck tyre sidewall cutter: £12,000-£18,000 Inclined conveyor (6-8m): £8,000-£12,000 Control system integration: £2,000-£5,000 (depending on automation level) Installation and commissioning: £3,000-£5,000 Total additional cost: £25,000-£40,000 beyond the baler itself
Annual throughput increase:
From the previous example: 122,000 tyres (standalone) to 250,000 tyres (integrated) = 128,000 additional tyres processed annually
Labour cost comparison:
Standalone (single operator):
Integrated (two operators):
Revenue from additional capacity:
Processing fee model: £0.50 per tyre processed
Less: Additional labour: £24,000 Net benefit: £40,000 annually
Payback period: £35,000 (integration cost) ÷ £40,000 (annual benefit) = 0.875 years (10.5 months)
Even in conservative scenarios (£0.30 per tyre processing fee), payback is under 18 months. For operations selling baled tyres with profit margins, payback is even faster.
Installing integrated systems requires a sequential approach and coordination.
Installation sequence:
Day 1: Baler installation
Day 2: Conveyor installation
Day 3: Cutter installation
Day 4: Integration and commissioning
Electrical integration requirements:
All equipment must be powered from the same distribution board (if possible) to simplify emergency stop wiring. Three-phase supply required for baler and cutter (conveyor can run single-phase if needed).
Total electrical load:
Verify the site’s electrical capacity before installation. Upgrading to 60A three-phase capacity costs £2,000-£4,000 if the current supply is insufficient.
Testing and fine-tuning:
Process 50-100 test tyres through the complete system to identify issues:
Most fine-tuning involves adjusting conveyor speed (VFD setting), repositioning discharge chutes, and marking optimal operator positions on the floor. Allow 4-6 hours for fine-tuning after the basic installation is complete.
Have questions about integrating tyre processing equipment? These answers cover the most common queries we receive from recycling operators planning their first integrated line or looking to upgrade existing equipment.
Minimum: Tyre baler (MKII or MK3), inclined conveyor (6-8m length), and optionally a sidewall cutter for truck tyres. Complete system costs £45,000-£70,000 including installation. Supporting infrastructure includes buffer zones, emergency stop integration, and operator stations. Most installations also include a forklift for bale handling and tyre movement.
50-70% improvement is typical. A standalone MKII processes 80 tyres/hour theoretically, 60-65 actual. The same baler integrated with cutter and conveyor processes 120-140 tyres/hour. The improvement comes from eliminating manual tyre carrying (which consumes 40-50% of operator time in standalone operation) and pre-cutting (which speeds compression by 15-20%).
Yes. If you have a standalone baler, you can retrofit a conveyor and/or cutter. Cost: £10,000-£25,000 depending on equipment. The baler doesn’t need modification; the ancillary equipment is positioned to feed the existing baler’s loading doors. Most retrofits install within 2-3 days with minimal disruption to ongoing operations.
One or two, depending on throughput targets. Single operator manages entire line in batch mode (90-110 tyres/hour). Two operators (one atthe cutter, one at the baler) achieve continuous flow (120-150 tyres/hour). Even a single-operator integrated setup outperforms standalone operation by 15-35% because pre-cutting and mechanical conveying reduce manual handling time.
15-18 metres length × 6-8 metres width for linear layout (90-144 square metres total). L-shaped or U-shaped layouts fit into 10m × 12m footprints (120 square metres). Space includes equipment, buffer zones, forklift access, and maintenance clearances. Ceiling height: 4 metres minimum to accommodate conveyor at peak elevation plus overhead clearance.
For operations processing 50,000+ tyres annually, yes. Integration costs £25,000-£40,000 but doubles throughput, which generates £30,000-£50,000 additional annual revenue (depending on processing fees or bale sales margins). Payback: 10-18 months typical. Below 30,000 tyres annually, a standalone operation is usually adequate, and integration ROI extends beyond 3 years.
Three options: (1) Manual – operator starts each machine independently, (2) Semi-automatic – emergency stops linked but start controls manual, (3) Fully automatic – PLC sequences all equipment from a single start button. Most installations use semi-automatic (safety interlocked) for the balance of simplicity and safety. Fully automatic adds £3,000-£5,000 but improves efficiency for high-volume operations.
Yes. Common approach: Start with a standalone baler (year 1), add a conveyor (year 2) after confirming volumes justify it, and add a sidewall cutter (year 3) if processing truck tyres. Staged implementation spreads capital cost over time and allows operational learning at each stage. However, installing a complete integrated line initially is more cost-effective (single installation project, better integration design).
Integrated tyre processing lines combining sidewall cutters, conveyors, and balers deliver 50% to 70% throughput improvements by eliminating manual material handling between processing stages.
A standalone MKII processes 60 to 65 tyres per hour, actual throughput. The same baler integrated with a cutter and conveyor achieves 120 to 140 tyres per hour. The equipment hasn’t changed; the workflow efficiency has.
Integration costs £25,000 to £40,000 beyond the baler itself (£10,000-£15,000 cutter, £8,000-£12,000 conveyor, £5,000-£8,000 installation and commissioning). For operations processing 50,000+ tyres annually, payback is 10 to 18 months through increased processing capacity.
Layout planning affects workflow efficiency. Linear layouts (15-18m length) are the simplest. L-shaped and U-shaped layouts (10m × 12m) fit constrained spaces. All layouts require 90 to 144 square metres, including access and maintenance clearances.
Operator training increases from 4 hours (standalone) to 8 hours (integrated) to cover equipment interaction and workflow sequencing. Single-operator integrated lines achieve 90-110 tyres/hour. Two-operator lines achieve 120-150 tyres/hour.
