Roller

Rollers are crucial components of belt conveyors, serving to support the conveyor belt and the materials being transported. They help reduce the running resistance of the conveyor belt and ensure that the belt’s sag does not exceed specified limits, thereby guaranteeing smooth operation. The roller structure consists of a roller body, bearings, seals, and other parts. According to their application, rollers can be categorized into types such as trough-shaped, parallel, and self-aligning. They are widely used in industries including mining, ports, and power plants.

  • The idler rollers feature high wear resistance, a low coefficient of friction, and are unlikely to damage conveyor belts. They boast excellent self-lubricating properties, eliminating the need for lubrication and ensuring smooth operation even under harsh conditions without getting jammed. They are antistatic, flame-retardant, resistant to aging, and highly tolerant to corrosion by acids, alkalis, and organic solvents. These rollers can withstand repeated impacts and vibrations. The operating temperature range is from -40°C to 90°C.

    It features excellent mechanical performance, lightweight design, easy installation, and maintenance-free operation; it also boasts stable operation and a long service life. Our factory also produces a wide range of conveyor belt-related products, fully capable of meeting your needs.

The fine sand recovery machine is a piece of equipment developed specifically for dewatering, media removal, and mud removal from slurry materials. It is also known as a tailings recovery machine, fine sand extractor, fine sand collector, silt-sand separator, slurry separator, or sand-water mixture treatment system, among other names.

The spiral sand washer utilizes the principle that particles of different sizes and densities exhibit varying settling velocities in a fluid: particles with fine size and low density settle slowly, while particles with large size and high density settle rapidly. This allows the machine to separate dust and impurities from the sand. Under the uniform agitation of the spiral blades, the machine achieves the purposes of filtering out water and impurities as well as lifting and conveying the sand.
