Product Description

Installed on the material-feeding spot to absorb the shock of falling down material and protect the belt and idlers from damage.
The impact Roller is used to slow down the impact of falling materials on the conveyor belt at the receiving part of the belt conveyor. It is mainly developed for corrosive environments such as coal washing plant, coking plant and chemical plant. It has more than 10 times the toughness of ordinary metal and five times the service life of traditional column shoes. It is corrosion-resistant, flame-retardant, antistatic and light self weight, It is widely used in mining. The special polymer material for Roller body has mechanical properties similar to bronze, good wear resistance, good self-lubricating performance and no damage to the belt. The buffer Roller has excellent anti-corrosion performance. The roll body and seals are made of polymer materials, which are corrosion-resistant. When used in corrosive occasions, the service life can reach more than 5 times that of ordinary Roller.
The buffer Roller has light weight and small rotation inertia. The special polymer material for Roller is light in weight, and its specific gravity is one seventh of that of steel. The weight of Roller made of this material is about one-half of that of ordinary Roller, with small rotational inertia and small friction between Roller and belt.
The buffer Roller is installed below the material receiving section of the conveyor to reduce the impact of materials on the conveyor belt during blanking and prolong the service life of the conveyor belt The spacing of buffer Rollers is generally 100-600mm.
In terms of installation, the first is to improve the installation density; Second, check frequently and replace the damaged Roller in time. For the conveyor belt with large drop, it is recommended to install buffer air lock and replace the buffer Roller with buffer bed. In terms of purchase, the following precautions are put forward according to the characteristics of buffer Roller: radial runout of Roller, flexibility of Roller, axial displacement, dustproof performance, waterproof performance, axial bearing performance of Roller, impact resistance of Roller, etc.
(1) Buffer Roller temperature protection
When the temperature of the belt conveyor drum exceeds the limit due to the friction between the drum and the belt, the detection device installed close to the drum sends an overtemperature signal. After receiving the signal, the receiver makes some actions after 3S delay, cuts off the power supply of the motor, and the conveyor stops automatically to play the role of temperature protection.
(2) Roller speed protection
In case of conveyor failure, such as motor burning, mechanical transmission part damage, belt or chain breaking, belt slipping, etc., the magnetic control 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 act according to the inverse time characteristic, and after a certain time delay, the speed protection circuit will act to make the executive part act, Cut off the power supply of the motor to avoid the expansion of the accident.
(3) Coal level protection of buffer Roller bunker
Two high and low coal level electrodes are set in the coal bunker. When the coal bunker cannot discharge coal because there is no empty vehicle, the coal level will gradually rise. When the coal level rises to the high electrode, the coal level protection will act. Starting from the first belt conveyor, each conveyor will stop in turn due to coal stacking at the tail.
