The impact crusher is a widely used crushing equipment in the field of ore crushing in China. It uses impact energy to crush materials. It is especially suitable for the processing of liquid stone. The compressive strength does not exceed 350 MPa and the side length is 100 to 500. The various ore resources of millimeters are evenly crushed. In fact, this range is very wide, so the status of impact crushers in the field of mining crushing is becoming more and more important. Impact crushers have a very significant advantage, which is to deal with high humidity The material has a very good effect, which is not achieved by many crushing equipment, and there will be no blockage during the crushing process.
1-needle sheet-like product Less content
The crushing principle of various crushing equipment has a great influence on the shape of the finished product. For example, the jaw crusher uses the principle of squeezing and crushing between two planes, so the crushed product The content of needle pieces is relatively large, generally above 15%, but the jaw crusher has higher productivity when crushing materials with greater hardness. The cone crusher adopts the principle of squeezing and crushing between two arc surfaces, so the needle The flake content is also relatively large, generally above 10%, the particle size of the cone crusher is more uniform, and the impact crusher relies on the impact force of the plate hammer and the impact plate to crush, so the processed finished product, needle The flake content is low, generally below 10%. Different types of crushers have different pin flakes content due to their principles. It is inevitable. Each type of equipment has its own advantages and disadvantages.
2 The blade hammer and the impact plate wear more seriously
Because the impact crusher uses impact energy to crush the material, the components that emit the impact force are the blade hammer and the impact plate, so these two parts are in the production process The wear is more serious. To solve the problem of serious wear, you must first select the right equipment. Although the impact crusher produced by each manufacturer uses the same material as the impact plate, the design of the components is different. If the nature and space design can be fully analyzed and optimized, the wear will be greatly reduced. Secondly, if you want to reduce the wear of the blower and the impact plate, it is recommended to use the impact crusher as the second-stage crushing equipment, and the first-stage crushing equipment chooses the jaw Crusher. The development of national engineering construction is in full swing, and higher requirements are put forward for the quality of various ore resources. For example, many fields require that the content of needle flakes in the finished product is less than 10%, so the impact crusher is more in the field of ore crushing. Indispensable.
