Arc-shaped toothed plate with large and small teeth on toothed roll crusher

Abstract

The invention discloses an arc-shaped toothed plate with large and small teeth on a toothed roll crusher. The arc-shaped toothed plate comprises an arc-shaped plate, wherein a plurality of groups of toothed rows are arranged on the cambered surface of the excircle of the arc-shaped plate in a circumferential direction and comprise a plurality of large teeth and a plurality of small teeth, and the plurality of small teeth are located between two adjacent large teeth in the toothed row respectively; a plurality of T-shaped mounting holes are respectively arranged in the arc-shaped plate axially, and a plurality of locating bosses are arranged on the cambered surface of the inner circle of the arc-shaped plate axially. The arc-shaped toothed plate is simple in structure, can improve the crushing efficiency, can uniformly crush grains with low excessively-crushing quantity, and is low in energy consumption and high in capacity, and the arc-shaped toothed plate is stable in installation and operation, has low noise and less dust, is less in noble metal consumption, low in manufacture cost and convenient in adjustment and maintenance, particularly solves the repairing problem of broken teeth and greatly reduce the equipment running and maintaining costs.

Description

technical field [0001] The invention relates to the field of crushers used for crushing mineral products, in particular to an arc-shaped tooth plate on a toothed roller crusher with large and small teeth. Background technique: [0002] With the rapid development of my country's economy, the scale of infrastructure construction is huge. The demand for building materials will be staggering. China is also a country with a large demand for mineral products. The mineral product processing market has broad prospects. At present, in China and even abroad, the crushing and processing equipment of mineral products has been hovering in the "one low" and "three high" of low efficiency, high energy consumption, high wear and high pollution. For example, "hammer crushers" and "impact crushers" have always been equipped with high power, heavy machine wear, low efficiency, high noise, and serious dust pollution. However, the old-fashioned "toothed roller crusher" still has defects su...

I applied for the patent No. ZL201020628553.9 and ZL201120485478.X on November 26, 2010. Although the fundamental problem of the crusher has been solved, the manufacturing process of the roller teeth on it is relatively complicated and the cost is relatively high. High, and there are no small teeth on the roller teeth, the crushing rate is relatively low
