OEM 63.5mm Dia Belt Conveyor Rollers For Corrosive Environments

Industrial Mining Used Steel Rubber Disc Idler Impact Conveyor Roller

Impact rollers are used to slow down the impact of falling materials on the conveyor belt at the receiving part of the belt conveyor. It is a type of rollers developed mainly for corrosive environments such as coal washing plants, coking plants, and chemical plants. Its inherent toughness is 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 in weight. It is widely used in mining. The special polymer material for the roller body has mechanical properties similar to bronze, has good wear resistance, and has good self-lubricating properties, and does not damage the belt. The Impact roller has superior anti-corrosion performance. The roller body and the seal are made of polymer materials, which are corrosion resistant. Used in corrosive occasions, the service life can reach more than 5 times that of ordinary rollers.

The Impact roller is light in weight and has low rotational inertia. The special polymer material for roller is light in weight, and its specific gravity is one-seventh of steel. The roller made of this material is about one-half of the weight of ordinary roller, and the rotation inertia is small. It is between the roller and the belt. The friction is small.

Impact roller temperature protection
When the belt conveyor roller and the belt friction cause the temperature to exceed the limit, the detection device installed close to the roller sends out an over-temperature signal. After the receiver receives the signal, a 3s delay will cause some actions to be performed, the motor power supply is cut off, and the conveyor automatically Stopping, play a role in temperature protection.

Speed protection of roller group
If the conveyor fails, such as the motor is burned, the mechanical transmission part is damaged, the belt or chain is broken, the belt slips, etc., the magnetic switch in the accident sensor SG installed on the driven part of the conveyor cannot be closed or cannot be closed at normal speed At this time, the control system will function after a certain delay according to the inverse time limit characteristic, and the speed protection circuit will take effect to execute some actions and cut off the power supply of the motor to avoid the expansion of the accident.

Impact roller coal bunker coal level protection
There are two high and low coal level electrodes in the coal bunker. When the coal bunker cannot cleave coal because there is no empty car, the coal level will gradually increase. When the coal level rises to the high level electrode, the coal level protection will start from the first belt conveyor. , Each conveyor stops in turn due to coal piled at the tail.
