Product Description
Product Introduction:
The centering rollers are used to automatically correct the excessive runout of the conveyor belt in operation to ensure the normal operation of the conveyor. The installation accuracy is high, especially for the conveyor which has set the front inclined rollers, the centering rollers can not be set. For conveyors that need to set centering rollers, generally there is 1 set of centering rollers in every 10 groups of rollers.
There are many types of spherical rollers, DTII(A) type belt conveyor is equipped with 2 types of spherical rollers, namely friction spherical rollers and conical spherical rollers, both of which can be used for reversible belt conveyor.
The friction roller is the necessary support device to solve the problem of conveyor eccentricity. Its main function is to prevent and control the "deviation" of the conveyor belt, prevent material leakage, improve transportation efficiency, and ensure safe, efficient and energy-saving transportation. Straightening rollers are widely used in mining, metallurgy, electric power, chemical, food and other industries.
