Effects of Crushing Teeth

 Mining crusher refers to the crushing machinery whose total content  is more than 50% ,the row compound particle size is greater than three millimeters. It is invented by British Hengan. according to the feeding and nesting size size,  crushing operations are often divided into coarse crushing , medium crushing, and crushing. The commonly used equipments are impact crusher, compound crusher, single stage hammer crusher, vertical crusher, gyratory crusher, roll crusher machines, double roll crusher, combo crusher, and so on.   
 
Breaking tooth width to the width of the crushing teeth refers to the size of the teeth in the axial direction along the tooth roller, referred to as the tooth width. Reasonable design of tooth width to strictly ensure product particle size and reduce the crushing rate and increase the strength of the broken tooth. Tooth width can not guarantee that the product design is too wide granularity; too narrow, decrease the broken tooth strength and increase the crushing rate. Due to the dimensions of the tooth width from the tooth root to the tooth tip is gradually becomes smaller, the tooth width of the tooth top at generally the tooth root of the tooth width of 3/4, the tooth width of the tooth root is generally preferably broken tooth pitch and product size difference.
   

The length of the breaking tooth breaking tooth length refers to the dimension along the toothed roller circumferential direction of the teeth, Acronym tooth length. Rational design of long teeth ensure product granularity to improve the capacity and service life of broken teeth withstand impact loads. Tooth length is divided into addendum long tooth root ratio addendum long, about 20 ~ 40mm, tooth root length depends on the diameter of the gear rolls in the cross section of the same tooth roller breaking machine number of teeth and broken teeth rotate when the line speed of the design, the general design of the tooth root length along the circumferential direction of the gear rolls on the front teeth and rear teeth and in the spacing of the tooth at the root of about 10 ~ 30 mm.
      

 To solve this problem only to increase this gap, but after increasing the spacing  gap, people will worry about the product particle size can not be guaranteed, in fact, after a lot of practice proved that as long as the line broken tooth rotation speed select the appropriate plus in a certain range The large spacing values can effectively improve the processing capability of the crusher and strict assurance granularity, the front teeth and rear teeth of the top spacing along the circumferential direction of the toothed roller is generally designed in the range of 50 ~ 150mm.
