Description

Technical Field

[0001] The utility model relates to the technical field of mine crushers, and more specifically, to a feeding hopper for a mine crusher which is convenient for feeding. Background Art

[0002] Mining crusher, also known as mining crusher, belongs to stone crushing equipment. Stone crushers are widely used in many departments such as mining, smelting, building materials, highways, railways, water conservancy and chemical industries. At present, the commonly used stone crushing machinery includes jaw crusher, impact crusher, air separation crusher, cone crusher, etc. At present, most of the feeding devices of mining crushers on the market are not convenient for feeding when in use. When too much material is added at one time, it is easy to cause material congestion and slow feeding. It is easy to feed unevenly during feeding, and even cause blockage and inability to feed, which greatly reduces the working efficiency of the crusher. In addition, it is impossible to control the amount of material added each time, and it is impossible to add material to the crusher quantitatively according to the working requirements. Adding too much material can easily cause internal blockage of the crusher and reduce its service life. Adding too little material will lead to the inability to fully utilize the crusher, which is easy to fail to meet the workload requirements and reduce the working efficiency. For this reason, we have launched the following device. Utility Model Content
