The type of crushing teeth broken tooth type is generally divided into the olecranon, javelin and cutting edge style,and so on. the Commonly used are the first two, because it can better reflect the role of the material stretching and chipping principle. Javelin-style welded wear-resistant alloy javelin mounted in the the teeth roll javelin seat, the advantages of this type is to replace a broken tooth convenient, but the cost is too high. Olecranon style is designed according to the wear-resistant alloy casting molding and arched teeth - body panels, the cost is low, easier replacement, types of the olecranon broken teeth. According to the cross-sectional shape ,it can be divided into quadrangular teeth Goryokaku teeth and hexagonal teeth. Front corner and rear corner rectangular tooth contact with the material edge, this tooth type generally used for the crushing refuse less raw coal. Front corner and rear corner hexagonal tooth contact with the material, there is a certain width of blade, to better reflect the role of the principle of material stretching and chipping, generally used for crushing raw coal refuse amount. Goryokaku teeth rake angle is only in contact with the material or the posterior horn at the edge of a certain width, its application range is between rectangular teeth and six-rowed between the teeth. The height of the crushing teeth height is designed according to the size of the teeth radially along the tooth roller, referred to as the tooth height. Tooth height reasonable design can improve the processing capacity of the impact crusher, reduce the the crushing energy required and strict guarantee product granularity. If the tooth height design unreasonable, the content is two high , this can improve the ability to bite into a chunk of material, but it can also cause the the superscalar product size; if its too low, then will reflect with broken teeth rotating wire-speed spent ,The adverse effects caused by the same. Therefore, during the design of the tooth height, the response to the product limit on the rate of hammer crusher, for scientific analysis, such as the product limit on the rate of the most demanding, the tooth height can be designed for similar requirements and product granularity; such as the rate on the product limit the requirements are not strict, to improve the ability to bite into a chunk of material may be appropriate to increase the size of the tooth height. This can impact the mining equipment crusher.
