【application】: applicable to machinery, metallurgy, mining, port, chemical and pharmaceutical, cement, building materials, steel, coal, etc .; is a variety of mobile belt conveyor drive device can also be used for fixed belt conveyor.

【products】: roller is divided into smooth, two kinds of plastic roller (which plastic sub-surface plastic drum and polyurethane two). in the power is not, the environment temperature can be used in the case of smooth roller. in the wet environment, power, easy to slip the case should be used plastic roller. which change the drum rubber surface recommended polyurethane, polyurethane wear resistance, and its wear resistance is 3-5 times the general rubber.

in this case,

the diameters of the reversing rolls are 250, 315, 400, 500, 630, 800, 1000, 1250, 1400, 1600 and 1800 mm.

in this case,

● according to the size of the drum bearing capacity, the structure of the drum steel welded structure, cast welding structure of the two. the cylinder and the connection plate of the cast-in-place drum were checked by the finite element method.

● there are two types of roller housings, one is integral type, the other is split type. each type can be equipped with ordinary self-aligning roller (column) bearings and self-aligning roller (column) bearings with adapter sleeve. the bearing manufacturer for the domestic kazakhstan, tile, luo, and other famous bearing factory, but also for foreign skf, fag and other manufacturers.

● roller are static balance test; national standards for large-size rollers have been tested after annealing and flaw detection factory.
