Ring Granulator Coal Crusher

Saturday December-06 2025 16:34:26

The Ring Granulator Coal Crusher crushes and granulates large coal lumps into the particle size required for power plants. Through the coordinated operation of a ring-shaped crushing chamber and a granulation mechanism, it processes lumpy and powdery coal into uniform particles with a discharge particle size of 1-10mm. This solves problems such as uneven raw coal particle size, inconvenient transportation, and incomplete combustion. It can also be used to process complex materials such as wet coal and sticky coal, improving coal utilization and reducing pollution. The crushing capacity is 5-50 tons per hour.

What are the advantages of the Ring Granulator Coal Crusher?

The Ring Granulator Coal Crusher features an integrated design of ring crushing and granulation, capable of crushing lumpy coal while directly pressing the crushed coal powder into uniform particles, reducing the hassle of secondary processing. The crushing chamber's wear-resistant lining is made of high-strength alloy material, offering impact resistance and wear resistance. The particle formation rate is over 90%, resulting in high-strength, non-pulverized finished particles that are easy to store and transport. It can process a wide variety of coal types, including coals of varying hardness and prone to caking, as well as wet coal with a moisture content of 8%-15%. Customization of output particle size, dimensions, and motor power is also available to meet specific site requirements.

How does the Ring Granulator Coal Crusher work?

When the Ring Granulator Coal Crusher is in operation, coal enters the annular working chamber through the feed inlet. The motor-driven annular crushing assembly, in conjunction with the fixed liner, generates compression, grinding, and shearing forces, gradually crushing large pieces of coal into fine particles. The internal design includes an anti-stick coating and a gap adjustment device to prevent clogging by wet coal and to meet different particle size requirements. The crushed coal particles are then graded by a bottom screen; qualified particles are discharged directly, while unqualified particles are returned to the chamber for secondary crushing.

What are the applications of the Ring Granulator Coal Crusher?

The Ring Granulator Coal Crusher is used to crush and granulate raw coal into uniform ring-shaped particles, improving coal utilization and facilitating transportation and storage. It is commonly used in coal mining, coal preparation plants, coal chemical production, thermal power generation, and boiler fuel preparation. It can crush anthracite, bituminous coal, lignite, lean coal, and coal with high moisture content or high hardness. In actual production, it is often used in conjunction with vibrating feeders and belt conveyors to achieve continuous feeding and material transfer, and with vibrating screens to complete post-crushing grading and screening. It can also be connected to coal granulators, dryers, and pulverizers to form a complete "crushing-grading-deep processing" production line, meeting the needs of coal crushing, purification, and resource utilization in different scenarios.
