Tire-Type Portable Crushing And Screening Plant

A tire-type mobile crushing and screening plant is a complete production line mounted on a wheeled chassis, integrating feeding, crushing, screening, and conveying systems into a single mobile unit . Unlike fixed crushing plants that require concrete foundations and permanent installation, the mobile plant can be transported directly to the job site by a tractor truck and begin production almost immediately.

The wheeled chassis design provides exceptional mobility—the plant features a short wheelbase, small turning radius, and high ground clearance, making it easy to maneuver on both ordinary roads and rough job site terrain . Once on site, hydraulic or manual jacks stabilize the unit for stable operation. For operations requiring 30 to 200 tons per hour, tire-type mobile crushing plants offer an ideal balance of capacity and mobility. They are widely used in construction waste recycling, quarrying, mining, and infrastructure projects where frequent site relocation is required .

Key Components: What Makes Up a Mobile Crushing Plant?

A complete tire-type mobile crushing and screening plant consists of five interconnected systems working in sequence :

1. Feeding System
A vibrating feeder mounted at the front of the plant receives raw material from excavators or wheel loaders. The feeder's grizzly bars allow fine particles to bypass the crusher, improving overall efficiency. This pre-screening function reduces wear on the crusher and increases throughput.

2. Crushing System
The crushing unit is the heart of the mobile plant. Depending on the application, the plant can be equipped with:

   ● Jaw crusher – for primary crushing of hard, abrasive materials

   ● Impact crusher – for secondary crushing with excellent cubical product shape

   ● Cone crusher – for tertiary and fine crushing

The crusher selection determines the plant's final product characteristics and capacity .

3. Screening System
A multi-deck vibrating screen (typically 3 decks) separates crushed material into different size fractions. Oversized material is returned to the crusher via a return conveyor for re-crushing in closed-circuit operation, ensuring all final product meets specification .

4. Conveyor System
Belt conveyors connect all components, transporting material between the feeder, crusher, screen, and final stockpiles. The conveyor system also handles the return flow of oversize material in closed-circuit configurations.

5. Mobile Chassis & Power System
The wheeled chassis supports all components and provides mobility. Power can be supplied by an onboard diesel generator set or external electrical connection, depending on site conditions .

Working Principle: How Does a Tire-Type Portable Crushing Plant Operate?

The operation follows a continuous material flow path :

   ● Raw material loading – Material is loaded into the vibrating feeder hopper by excavator or wheel loader

   ● Feeding – The feeder uniformly delivers material to the crusher while pre-screening fines

   ● Primary crushing – Material is reduced to intermediate size

   ● Conveying – Crushed material moves to the screen

   ● Screening – Material is separated into finished fractions; oversize is returned for re-crushing

   ● Finished product stockpiling – Different size aggregates are discharged to separate stockpiles

The plant can operate in various configurations: "crush first, screen later" or "screen first, crush later," depending on material characteristics and product requirements . Multiple mobile plants can be combined into two-stage or three-stage crushing and screening systems for more complex applications .

Key Advantages: Why Choose Tire-Type Over Other Options?

1. Superior Mobility and Quick Setup
The tire-type mobile plant requires no concrete foundation or fixed installation. It can be towed directly to the working site and begin production immediately, dramatically reducing project preparation time .

"One day you are processing construction waste in Area A, and the next day you can move to the mining face in Area B," explains site managers who use this equipment .

2. Reduced Material Transportation Costs
Following the principle of "process material at the source," the mobile plant crushes material on-site, eliminating the cost of transporting raw material to a fixed plant location. This significantly reduces overall operating costs .

3. Integrated, Space-Saving Design
The integrated unit design eliminates the need for separate equipment installation, reducing material consumption, labor hours, and site space requirements .

4. Flexible Configuration Options
The plant can be configured as:

   ● Single unit – Standalone operation

   ● Two-stage system – Coarse + fine crushing

   ● Three-stage system – Coarse + medium + fine crushing

   ● Crush-first or screen-first – Adaptable process flow

5. Cost-Effective Investment
While tire-type plants have higher upfront costs than stationary equivalents, their mobility and quick deployment enable operators to take on projects that stationary plants cannot—opening new business opportunities and delivering faster returns on investment .

Baichy Machinery Case Study: 50 TPH Portable Crushing Plant in Kenya

Customer Challenge: A Kenyan aggregate supplier needed to serve multiple project sites but relied on a single fixed crushing plant. High material haulage costs and long transport times were cutting into profits and limiting their ability to take on new contracts.

Baichy Solution: A tire-type mobile crushing and screening plant configured for 50 TPH, comprising:

   ● PE400x600 jaw crusher (primary)

   ● PF1007 impact crusher (secondary)

   ● 3YK1537 vibrating screen

   ● Closed-circuit return conveyor

   ● Onboard diesel generator

The plant was factory-tested, shipped, and commissioned on-site with operator training.

The tire-type mobile crushing and screening plant represents a strategic solution for aggregate producers, construction contractors, and mining operators who need processing capability that can move with the material. For the 30-200TPH capacity range, these plants deliver an ideal combination of mobility, productivity, and cost-effectiveness.
