Product description

The Coal Classification Crusher is suitable for coal mining, chemical construction and other industries, and is more suitable for crushing raw coal (including gangue) in large coal mines or coal preparation plants. The grading crusher has both screening and crushing functions and crushing capacity. The motor and reducer are linked by a distance-limiting hydraulic coupling to prevent power overload and sensor overload protection, making it safe and reliable. The gear pitch is hydraulically adjusted, and the gear roller bearings are lubricated centrally. Optimized tooth shape design, selective crushing by tension and shear force, high efficiency, low consumption, and uniform granulation.

Why choose Huashengming

1. Special cavity shape and tooth shape: Change the traditional Coal Classification Crusher to crush materials by impact and extrusion, and at the same time realize the gap between teeth for material classification and screening.
2. Low-speed, high-torque transmission system: The new transmission structure and gear roller structure greatly improve the crushing processing capacity, automation level and reliability.
3. Various automatic protection devices: Equipped with a variety of automatic protection devices, automatic and regular filling of lubricating oil, and automatic centralized programming control.
Applicable materials
It can be used to crush surface rocks, coal, limestone, clay ore, iron ore, gold ore, uranium ore, nickel ore, bauxite ore, talc, gypsum, coke, glass, etc.

Performance advantages

1. Small height and compact structure
2. The special gear tooth structure makes it suitable for dry ore, wet ore, mud ore and sticky ore.
3. Reasonable structure, no clogging, no stickiness
4. Large processing capacity, up to 14000t/h, high crushing strength, can crush materials with pressure resistance up to 300MPa
5. Hydraulic coupling and electronic control double overload protection are adopted. When overloaded or difficult-to-break materials are encountered, the crusher stops rotating and the crushing roller reverses to discharge the difficult-to-break materials.
6. Easy maintenance and repair

Sand Production Application

In sand production lines, the double-roll crusher functions as a sand-making machine, offering advantages such as no wear parts, low maintenance costs, adjustable sand particle size, high yield rate, and excellent sand particle shape. It is widely used in the sand-making industry.

Mineral Processing Crushing Applications

In the mineral processing industry, double-roll crushers or high-pressure roller mills are employed for fine crushing operations. Positioned upstream of ball mills, they can reduce 2-3 cm ore particles to less than 1 mm, significantly enhancing the operational efficiency of mineral processing ball mills and boosting overall production productivity.    

The coal classification crusher is equipped with two horizontally installed and parallel toothed rollers in the crushing cavity. The toothed rollers have crushing teeth on the surface. The toothed rollers rotate with each other through a transmission device (single motor drive or dual motor drive), relying on impact shearing and impact. The effect of stretching causes the shearing force to generate huge crushing force along the weak and fragile parts of the material to break it. The material is discharged between the two crushing rollers and between the comb plates on the side wall. After crushing, the product is controlled by this gap and will not produce excessively large particles. Moreover, materials that already contain qualified particle size in the feed will also Eject quickly to avoid repeated crushing. Reduce the powder extraction rate and increase the output.
