High Strength Sizer Crusher

Product description

High Strength Sizer Crusher is applicable to industries such as coal, metallurgy, mine, chemical industry and building materials etc. And it applies to crushing of raw coal (including gangue) in large scale coal mine or coal preparation plant. Sizing crusher has the ability to screen as well as crushing and the capacity to crush is strong, motor and speed reducer are connected by constant filling fluid coupling to avoid dynamic overload, overcurrent protection of the sensor is safe and dependable. Interval between tooth and roller is regulated by hydraulic pressure and conduct centralization lubrication to roller bearings. Tooth profile is of optimization design, shearing force conduct selective crushing, efficient and low power consumption, the granularity is uniform.

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.    

High Strength Sizer Crusher is a low speed, high torque through type screening crusher (50-80 rpm). According to the crushed material and the particle size of the crushed material, the rotational linear speed of the tooth tip of the crusher’s toothed roller can be as low as 0.8 meters/second (primary crushing) and not more than 1.8 meters/second (third/fourth stage crushing). By using low rotational speed, high torque, and different tooth shapes to achieve the final product particle size required by users, and reducing the possible over crushing to a minimum, the crushing of high hardness ores is met. Its typical structure is motor – fluid coupling – reducer – toothed roll shaft assembly and crushing chamber box.

The working principle of this machine is to rely on the effects of impact shearing and impact stretching, causing the shear force to generate a huge crushing force along the weak and fragile parts of the material, causing it to break. The material is discharged between two crushing rollers and the comb plate on the side wall. After crushing, the product is controlled by this gap and will not produce too large particles. The material that already contains qualified particle size in the feed is quickly discharged and is not affected by crushing. It has good particle size control and screening effect, and the product particle size is uniform.
