## Product definition

A tire type mobile crushing plant is a complete crushing and screening circuit permanently mounted on a road-legal semi-trailer chassis. It differs from a tracked crawler crusher in that it cannot move under its own power: it is towed between sites by a standard tractor truck, requires reasonably level ground, and is positioned once for the duration of the job. Choose the tire type when sites are accessible and relatively flat; choose tracked when gradient, soft ground or daily repositioning dominate.

Key figures: input size 0–930 mm (coarse crushing reference) · capacity 0–650 t/h (coarse crushing reference) · seven series covering primary crushing, secondary/tertiary crushing with screening, combined units, sand making and shaping, fine crushing with sand washing, three-in-one and four-in-one units.

## Working principle (5 steps)

1. Transport and positioning — a standard tractor truck tows the semi-trailer chassis on public roads.
2. Levelling and unfolding — hydraulic outriggers level the chassis off its axles; discharge and side conveyors unfold and hopper walls rise. No concrete foundation.
3. Regulated feeding — a vibrating feeder with grizzly section draws material from the hopper at a controlled rate; fines smaller than the grizzly gap bypass the chamber and join the discharge belt.
4. Crushing — material is reduced by compression (jaw, cone) or impact (impact crusher, VSI). Discharge setting is hydraulic; tramp iron protection releases uncrushable objects.
5. Screening and conveying — a 2 or 3 deck inclined vibrating screen classifies the product; oversize returns to the crusher in closed circuit and sized fractions travel to stockpile.

Main structural systems: semi-trailer chassis, hopper and vibrating feeder, crushing host, vibrating screen, belt conveyors, power unit (diesel generator or electric motor), hydraulic system, centralised control cabinet.

## Module selection

- Jaw module — primary reduction of hard and abrasive rock, max feed up to 930 mm.
- Cone module — secondary/tertiary duty on hard, abrasive or silica-rich feed; low flakiness, low wear cost.
- Impact module — excellent cubical shape; ideal for limestone and demolition concrete.
- Vibrating screen module — 2 or 3 decks, sizes 1548/1848/1860/2160, can run standalone behind any primary unit.
- Sand making and shaping module — VSI host converts 0–40/45 mm feed into manufactured sand; optional air or water classification.
- Three-in-one and four-in-one modules — feeder, primary, secondary and screen on one trailer.

## FAQ summary

- Tire type versus tracked: tire type is towed, needs level ground, costs less; tracked self-propels, handles rough ground and repositions continuously, costs more.
- Foundation: no concrete foundation in normal ground conditions; a compacted level platform is required.
- Relocation: typically a half-day move plus a short test-run, against weeks of civil works for a fixed line.
- Capacity selection: start from saleable tonnage, account for reduction ratio, discarded fines and loader availability.
- Host swap: the modular chassis allows the crushing host to be changed without replacing the trailer.
- Drive: diesel generator for grid-free sites, electric motor where mains power exists, or electric with generator backup.
- Wet feed: grizzly feeder removes fines and soil; consider pre-screening, larger apertures, polyurethane media or a washing module.
- Dust and noise: sealed transfer points, skirting and spray nozzles as standard; enclosures, bag filter and acoustic treatment optional.
- Transport: width typically 2.6–3.2 m and height around 4.5 m folded; certified dimensional drawings supplied with each quotation.
- Spare parts: original parts supplied worldwide, cast and machined in-house.
- Warranty: 12 months covering manufacturing defects; wear parts excluded; lifetime support thereafter.
- Reinforced concrete: yes, with an impact host and magnetic separation of rebar.
- Quotation inputs: material type and strength, max feed size, required t/h, output fractions, site conditions, power availability, destination port.
