6204 Double Sealed Bearing Impact Idler Roller For Mining Industry
High Quality Mining Industry Belt Conveyor Carrying Impact Roller
Conveyor Impact rollers are used to reduce the impact of falling
materials on the conveyor belt at the receiving part of the belt
conveyor. It is mainly a type of roller developed for corrosive
environments such as coal washing plants, coking plants, and
chemical plants. It has inherent resistance. It is more than 10
times that of ordinary metals, and has a life span of five times
that of traditional pillar shoes. It is corrosion-resistant,
flame-retardant, anti-static, and light weight. It is widely used
in mining.
The Impact roller is to improve the density of the device in terms
of the device; the other is to check frequently and replace the
damaged roller in time. Regarding the conveyor belt with large
blanking drop, it is recommended to install a Impact air lock
device, and replace the Impact roller with a buffer bed. In terms
of purchase, the following points are put forward based on the
characteristics of the Impact roller: the amount of radial runout
of the roller, the sensitivity of the roller, the amount of axial
movement, the dustproof function of the roller, the waterproof
function, the axial bearing function of the roller, the support
Roll anti-impact function, etc.
The Impact roller is applied to the tailstock of the machine
according to the actual situation. When receiving the material, it
can reduce the impact of the material on the belt, which is
beneficial to the service life of the long belt. The trough-shaped
roller is generally composed of two side rollers and a flat roller.
The groove angle is generally 30 degrees. For a detachable belt
conveyor, the three rollers of the trough-shaped roller are hinged
to each other, so Called hinged roller. The parallel roller is
generally a long roller, which is installed at the lower end under
pressure, so it is called the lower roller.
