Use and working principle
Impeller coal feeder is mainly used for power plant, coal, mine, chemical industry and other industries in supporting the achievement of conveyor powder, crystalline materials, such as the continuous feeding. It walks before and after along the track which between the pre-groove through the device, the impeller is driven by driving device. Materials on both sides of the pre-groove allocated for homogeneous slit trench on the conveyor belt, it not only can be feeding when it’s walking, but also from time to time to feed, to achieve uniform delivery of materials.
Structure and feature
Impeller coal feeder is made up of driving device, impeller gear, road gear, electrical control and rack. Products use frequency to control speed. Its features as following:
1. Product design based on the user's different requirements, there are sub-portal, bridge and unilateral and bilateral, and on the allocation of material and allocated material, which is expected to meet the requirements of users.
2. Feeding mechanism of the allocation of products can allocate material when is walking along the track before and after, non-air travel, but also can be set when the call is expected.
3. Allocated material bodies set up frequency control, it can be adjusted according to the scene requirements, energy consuming is small, and operation is safe.
4. Allocated material and running gear set up an independent driving device. Four driving wheels have good synchronization. It’s easy to installation and maintenance.
5. Box-type structure, the structure is new and beautiful.
