The new teeth-roller cone crusher is very different from the traditional one in the structural design. The new teeth-roller cone crusher adopts a brand-new structural design concept. The external toothed plate and the internal toothed plate of this equipment forms a reverse cone-shape crushing chamber which enhances the crushing efficiency of the first-stage crushing. It is a typical powerful necking-in crushing chamber. Although the s cone crusher and large-sized gyratory crusher in the market adopt the reverse cone-shaped crushing chamber, their structuring model is different.
The chamber types of traditional cone crusher can be divided into three types: standard type, medium type and short-headed type. These three chamber types can be used in the coarse crushing, medium crushing and fine crushing respectively. The division method bases on the size of the materials feeding mouth and the length of the parallel area. That the size of the materials feeding mouth is relatively small and the parallel area is the longest is the short-headed chamber type; that the size of the materials feeding mouth is relatively big and the parallel area is the shortest is the standard chamber type; that the size of the materials feeding mouth and the parallel area are medium is the medium chamber type. Of course, there is exception, for example, the pew jaw crusher has only two kinds of crushing chambers, namely, standard type and short-headed type.
The external toothed plate and the internal toothed plate of the new teeth-roller cone crusher forms a reversed cone-shaped chamber, and they forms a outward opening parallel area, whose gap is predetermined, as a result of which, it limits the granularity of the discharged materials so that the product granularity is evener. After the materials enter the reverse cone-shaped crushing chamber, their position will be determined by the two teeth on the toothed plate, and the teeth will exert force on the materials to bend and cut them. Likewise, the crushing process of the second stage crushing chamber is the same with that of the first stage crushing chamber. The third stage crushing chamber is mainly used for fine crushing and materials discharging.
