Coal Coarse Crusher

What is Coal Coarse Crusher?

Coal Coarse Crusher is a primary crushing equipment for processing large pieces of raw coal. It can crush the mined raw coal or coal gangue (up to 1800mm) into a particle size suitable for transportation or further processing (usually below 300mm). The equipment adopts high-strength alloy materials and modular design, optimizes the crushing structure according to the characteristics of coal hardness (Mohs hardness 1.5-4) and moisture content (0-30%), and can achieve a crushing ratio of 1:5-1:8. It is currently widely used in coal mining, coal washing plant pretreatment, coal chemical raw material preparation and other scenarios. Compared with traditional crushing processes, it can improve processing efficiency by 30% and reduce energy consumption by more than 25%.

In view of the characteristics of coal materials with moderate hardness but easy to generate dust, our Coal Coarse Crusher is specially designed with dust-proof sealing system and wear-resistant parts to ensure that the equipment can reduce dust pollution and component wear while crushing efficiently, thereby extending the service life of the equipment. The equipment is made of heavy steel structure, and key components such as gear rollers and hammer heads are made of high-chromium alloy wear-resistant materials. It can run continuously and stably for more than 8,000 hours without major repairs.

What types of Coal Coarse Crusher are there?

Coal Coarse Crusher can be divided into jaw type, cone type and impact type, and the corresponding model can be selected according to the particle size of the crushed coal.

Why choose Coal Coarse Crusher?

Large feeding capacity: The large feeding port designed for coal can directly handle large pieces of raw coal (up to 1800mm) mined from the mine, reducing the pre-crushing process.

High-efficiency crushing: The optimized crushing chamber and motion parameters increase the processing capacity of the coal coarse crusher by 30-50% compared with ordinary crushers, and reduce unit energy consumption by more than 20%.

Maintaining the lump coal rate: The principle of graded crushing can maintain the lump structure of coal to the greatest extent, and the lump rate is 5-7% higher than that of traditional crushers, which improves the economic value of coal.

Strong adaptability to wet coal: The special tooth design and anti-blocking structure can handle wet coal with a moisture content of more than 15%, without sticking or blocking, ensuring continuous production

What are the applications of Coal Coarse Crusher?

Coal Coarse Crusher can be used to crush coal with a particle size of 0-1800mm. It is commonly used in open-pit coal mines, underground coal mines, coal preparation plant pretreatment, thermal power plants, coal logistics centers, coking plants, coal gasification/liquefaction, etc.

Crushing effects for different types of coal:

Lignite: Use a low-speed, high-torque toothed roller or ring hammer coarse crusher to avoid excessive crushing and powder.

Bituminous coal: Suitable for all types of coarse crushers, select the discharge particle size according to the subsequent process requirements.

Anthracite: It is recommended to use a jaw or graded coarse crusher to cope with higher hardness.

High-moisture coal: Choose a ring hammer or special toothed roller coarse crusher with anti-blocking design.

Gange-containing coal: Use a jaw or gyratory coarse crusher with high crushing force to ensure effective crushing of gangue.

Coal Coarse Crusher Customer Cases

Our Coal Coarse Crusher has been successfully applied to many large coal mining projects around the world:

An open-pit coal mine in Australia: Using FP500 graded toothed roller coarse crusher with a processing capacity of 2500t/h, crushing 1800mm raw coal to less than 300mm, the equipment has been running continuously for 5 years without major repairs.

Zhungar Coal Mine in China: Two graded coarse crushers are used for high-quality coal and low-quality coal crushing production lines respectively. They have been in operation since 1993 and still maintain good performance.

South African coal mine project: A crushing system consisting of 47 small and medium-sized coarse crushers and 13 large machines can adapt to diverse mining conditions.

Indonesian lignite project: Using anti-blocking hammer coarse crusher, successfully processing lignite with a moisture content of 18%, with a production capacity of 1200t/h
