Impact Crusher For Coarse Coal Crushing

Wednesday December-03 2025  16:46:19

Impact Crusher for Coarse Coal Crushing is a type of crusher used to break larger raw coal particles (300-1200mm) into smaller particles suitable for subsequent coal processing. It achieves crushing by rapidly rotating a rotor that drives hammers to impact, collide, and shear the coal. The crushed particle size is between 20-100mm, and can generally be adjusted by controlling the gap between the impact plates. It has a high crushing ratio and produces a wide range of particle sizes. A single unit can handle 50-500 t/h.

Impact Crusher for Coarse Coal Crushing can also handle medium-hardness, brittle coal. Its hammers, impact plates, and other wear-resistant parts are made of high-chromium alloys and chromium-manganese alloys. The machine body is welded from carbon steel, providing strong impact resistance and wear resistance, making it suitable even for processing hard coal such as coal gangue.

What types of impact crushers are available for coal crushing?

Impact crushers for coal crushing mainly come in two types, vertical and horizontal, depending on the application. They differ in structure and the materials they can be used with.

Vertical impact crushers for coal crushing: These are small in size, occupying only half the space of horizontal crushers. They are commonly used in small to medium-sized coal mines or underground crushing operations with limited space. They use vertical feeding and crush coal through impact and grinding, resulting in uniform crushing with cubic particles. The output particle size is 20-80mm, and the output is typically 50-300t/h. They can process coal with medium hardness up to 800mm and can also be used for coal with high moisture content.

Horizontal Impact Crusher for Coarse Coal Crushing: The structure is horizontal, allowing for larger feed sizes up to 1200mm. It crushes coal through horizontal rotor impact, with an adjustable output size of 25-100mm and a processing capacity of 100-800t/h. It can be used to process medium-hard or higher coals such as coking coal and lean coal.

What are the advantages of Impact Crusher for Coarse Coal Crushing?

Impact Crusher for Coarse Coal Crushing uses high-manganese steel hammers and wear-resistant liners, along with an integrated frame, ensuring machine stability and service life. It can process various types of coal with a moisture content ≤15% and compressive strength ≤150MPa, with a processing capacity ranging from 50-500 tons/hour. It utilizes impact force for efficient crushing, producing uniform output particle size (adjustable from 20-100mm) with an over-crushing rate of <8%. We can also provide customized solutions based on customer production site and capacity requirements, adjusting machine size, output particle size, and motor power (37-200kW, etc.).

How does Impact Crusher for Coarse Coal Crushing work?

During the operation of Impact Crusher for Coarse Coal Crushing, raw coal enters the equipment through the feed inlet. The guide plate at the feed inlet evenly delivers the raw coal to the high-speed rotating rotor. The rotor is equipped with many impact hammers, which swing at high speed under the action of centrifugal force. When the raw coal hits the impact hammers, it is instantly crushed into small pieces. The crushed coal pieces fly towards the lining plates on the inner wall of the equipment, where they are impacted and bounced again, further crushing them. Finally, the coarse coal particles that have reached the preset particle size are discharged through the discharge port at the bottom of the equipment, while the large particles that have not been crushed enough are repeatedly impacted inside the equipment until they meet the requirements before being discharged.

What are the applications of Impact Crusher for Coarse Coal Crushing?

Impact Crusher for Coarse Coal Crushing can be used in coal mining, coal washing plants, thermal power plants, chemical and building materials industries to process large coal lumps with a compressive strength ≤150MPa, moisture content ≤18%, moderate hardness, and good brittleness, with a particle size not exceeding 1200mm. It can crush anthracite, bituminous coal, lignite, coking coal, lean coal, and sub-bituminous coal. Through impact force, it crushes coal into coarse particles of 40-150mm, providing raw materials for subsequent grinding, screening, or direct combustion.

Impact Crusher for Coarse Coal Crushing Solutions

A large open-pit coal mine in Pakistan has adopted the PF series Impact Crusher for Coarse Coal Crushing for primary raw coal processing. This system crushes bituminous coal with a compressive strength ≤350MPa and a particle size not exceeding 350mm. The equipment operates at a stable crushing capacity of 100t/h. Utilizing high-speed hammer impact and a multi-chamber crushing design, the output particle size is precisely controlled to ≤50mm, resulting in a uniform cubic shape with a low over-crushing ratio, effectively preventing subsequent conveyor blockages. The crushed coal can be directly supplied to power plants for combustion without secondary processing, ensuring continuous production line operation and improving coal combustion efficiency.
