The apron feeder, also known as the plate feeder, is mainly used to continuously and evenly supply and transfer various large heavy objects and materials to the crusher, batching device or transportation equipment along the horizontal or inclined direction from the storage bin or transfer hopper. For abrasive bulk materials. It is one of the important and essential equipment in the process of ore and raw material processing and continuous production.
The apron feeder is composed of silo interface, guide chute, gate device, transmission plate device (chain plate chain), drive motor, drive sprocket group, underframe and other parts. All parts are connected, transported and assembled by bolts. It can be separated and integrated, and it is applicable to both ground and underground.
The apron feeder is suitable for conveying some materials with high temperature, large lumpiness, sharp edges and corners and grindability (the controllability of grinding and carving. In short, the difficulty and controllability of cutting during processing.) Strong solid materials are widely used in building materials, metallurgy, electric power, coal, chemical industry, casting and other industries. Plate feeder is generally divided into three types: heavy plate feeder, medium plate feeder and light plate feeder, which are commonly used in concentrating mill.
Heavy-duty apron feeder is an auxiliary equipment of transportation machinery. It is used in the crushing and classification workshop of large concentrators and cement, building materials and other departments as a continuous and uniform feeding from the silo to the primary crusher. It can also be used for short-distance transportation of materials with larger particle size and specific gravity. It can be installed horizontally or obliquely. In order to avoid direct impact of materials on the feeder, the silo is required not to be unloaded.
The heavy-duty apron feeder has the following characteristics:
1. Safe and reliable operation, easy to use.
2. The chain plate is welded by lap joint, so there is no material leakage, deviation and good wear resistance. In addition to the support of the roller, the chain belt is also provided with a slide rail support.
3. The chain belt tension device is equipped with a buffer spring, which can slow down the impact load of the chain and prolong the service life of the chain.
4. The driving device is suspended on the main shaft of the machine and is not connected with the foundation, so it is easy to install and disassemble, and has the advantage that the meshing performance of the reducer gear is not affected by the accuracy of the foundation.
5. The drive adopts a large speed ratio DC-AC reducer, which reduces the transverse size of the machine and facilitates the process layout.
6. Through the electric control device, the plate feeder can automatically adjust the feeding speed of the feeder according to the load of the crusher, so that the crusher can receive material evenly, work stably, and realize the automation of the system.
