sizing crusher coal crusher price for raw coal / lignite coal/ coal gangue

Application scope:

This series of crushers is mainly suitable for coarse and medium crushing operations.

▶Coarse and medium crushing operations for coal preparation plants, open-pit coal mines, and underground coal mines.

▶Crushing and medium-sized crushing operations for limestone, ores, oil shale, iron ore, gold ore, copper ore, lead-zinc ore, nickel ore, etc. in open-pit mines.

Crushing operations for power plants, power plant coal, and power plant slag, etc.

Working Principle:

The crusher is driven by an electric motor through a reducer to rotate the two toothed rollers in opposite or parallel directions. When the material enters the crushing chamber through the inlet, the two toothed rollers with rotating teeth first screen the material. The material that meets the requirements passes through the teeth and enters the discharge chute. The large pieces of material are broken, sheared, and stretched by the teeth of the toothed rollers and discharged from the discharge outlet.

Performance Features:

▶ The crusher is mainly composed of an electric motor, a limiting torque hydraulic coupling, a connecting cover, a reducer, a coupling, a pair of rollers, and a machine body.

This crusher adopts shearing crushing technology, which basically eliminates over-crushing. It is small in size and light in weight, suitable for primary, secondary and tertiary crushing systems in underground mines, factories, and open-pit operations.

A crushing bar can be added at the bottom of the box to increase the crushing ratio through secondary crushing and achieve adjustable discharge particle size.

The equipment is equipped with side comb teeth plates, which can be adjusted by adjusting the spacers to adjust the discharge particle size. During operation, the distance between the two teeth rollers and the distance between the teeth roller and the side comb teeth plate remain constant, ensuring stable discharge particle size.

The tooth plate installation method adopts a single-sided tongue-and-groove structure (patent of our company), which enables quick replacement of the tooth plate and reliable operation.

The electric control system is controlled by PLC, which realizes the program control of the equipment's feeding and discharging processes, achieving high automation.

The equipment adopts modular design, with interchangeable crushing disc side teeth and teeth rolls, which improves the equipment's versatility and reduces daily maintenance costs.

▶ The core component of the gear roller shaft in the equipment is a large clearance self-aligning roller bearing, made by SKF, an imported bearing manufacturer, which is recommended by mining machinery for its strong resistance to shock and impact and long service life. The lubrication system uses centralized automated oil supply, reducing the labor intensity of workers and ensuring safety and reliability. It is convenient and quick.


The machine has the following outstanding advantages: compact structure, stable operation, small size, and high production capacity, which makes it very suitable for use in underground mines or confined spaces.

The crusher has dual overload protection, ensuring safety and reliability.
