Crushing Teeth Arrangement

In general, small crushing previous tooth horn back and horn have the trend of making broken teeth bow downward, which can improve the ability to impact loading broken tooth, but it will reduce the ability of broken teeth to bite the bulk material; broken tooth rake angle and rear horn have the trend of rising broken teeth, which can improve the ability to broken teeth biting chunk of material in Taiwan, but it will reduce the ability of the broken tooth to withstand the impact load. Broken teeth of the earlier horn and rear horn should be within a certain range, the rake angle is usually 70 degrees to 80 degrees, posterior horn is usually 40 degrees to 50 degrees. Mining crusher refers to the crushing machinery whose content is more than 50% of the total content, the row compound particles size is larger than three millimeters. It was invented by British Heng. According to the the size of feeding and nesting coexistence, the crushing operations is often divided into the rough crushing, medium crushing and fine crushing. Gravel equipments are jaw crusher, impact crusher, impact crusher, crusher compound, single-stage hammer crusher, vertical crusher, gyratory crusher, cone crusher, roll crusher machine, double roll crusher, crusher two-in-one, and so on. With the increase of the the addendum pitch along the circumferential direction on the front and rear gear roll roll gear, the ability to bite into a chunk of material increase, the product particle size also increased, but there is a limit about the addendum spacing increase, if poorly designed, it will result in tooth roof pitch too small, the elevation of the front teeth will take bulk materials high when the back teeth can not bite the bulk material. The proper crushing teeth and crushing teeth arrangement can reflect the grading crusher power is low, the advantages of a large processing capacity is large these advantages, but there are a number of factors that the impact of the crusher is only qualitative understanding, such as crushing teeth in the rotation when the line speed and along the tooth the relationship between the gear and rear gear tooth tip spacing on the front of the roller circumferential direction. And a certain body design with the current conditions, such as feed particle size characteristics, into the material hardness, many aspects of the product particle size characteristics, which need to strengthen research on the basic theory of jaw crusher and the long period of accumulation and exploration.
