What models of small coal crushers are available

Small coal crushers, also known as small coal grinding machines, are used to crush various types of coal for applications in power plants, industrial boilers, construction, and metallurgy. For small and medium-sized enterprises, small coal crushers are sufficient to meet production needs, as they are lightweight, require minimal floor space, and are easy to operate. What specific models are available?

Coal is primarily composed of elements such as carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus. It is a solid combustible mineral formed underground through complex biochemical and physicochemical processes. It ranges in color from brown to black and exhibits a dull to metallic luster. Depending on the degree of coalification, its hardness generally falls between 1 and 4 on the Mohs scale. Therefore, for small coal crushers, hammer mills, double-roll crushers, and two-stage crushers, with 20 models available.

01 Hammer Crusher

Feed Size: ≤100mm

Processing Capacity: 3–95 t/h

Utilizing innovative crushing technology, this machine relies on the impact of hammer heads to crush materials of varying sizes in a single pass, simplifying workflows and increasing throughput. By changing the chamber type, it can switch between coarse, medium, and fine crushing, eliminating the need for a primary crushing stage. It delivers high yield rates with no flaky particles; the multi-angular, multi-faceted particles ensure high compressive strength. The screen gap can be adjusted as required to alter the output particle size, resolving the traditional issues of clogging, jamming, and low output.

02 Double Roll Crusher

Feed Size: ≤30mm

Capacity: 3–110 t/h

Featuring a roller design, this machine crushes material using the powerful pressure generated by two counter-rotating rollers. A wedge or shim adjustment mechanism is installed between the rollers. The roller liners have a long wear cycle, and wear-prone components are made of new high-strength, wear-resistant materials, resulting in minimal wear and a long service life. The design typically incorporates a dual-motor drive system, providing greater power while saving energy.

03 Two-Stage Crusher

Feed Size: ≤200 mm

Processing Capacity: 10–300 t/h

Two sets of rotors are used in series, with the upper and lower stages of crushing performed by the dual rotors to achieve both hammer-to-material and material-to-material crushing effects. The bidirectional gap adjustment technology allows for adjustable output particle size and a low over-crushing rate. With no screen mesh or grate at the bottom, it prevents clogging even with high-moisture materials. The unit is equipped with a counterweight balance wheel, ensuring smooth operation with high inertia and reduced power consumption. Additionally, the gap-adjustment technology allows hammer heads to be repositioned and reused after wear, with a single set of hammers lasting as long as three sets, resulting in low overall operating costs.
