Assembled crusher

Abstract

The invention relates to an assembled crusher. A main shaft is in keyed joint with a movable conical sleeve and a grinding-base support sleeve, wherein the grinding-base support sleeve is connected by a pressure bearing and an upper case of a reducer. A bearing sleeve and a shaft sleeve ray lid are arranged outside the bearing of a main shaft and connected with an upper external ring, a transition ring and an external ring of the upper case of the reducer from top to bottom. The external conical round surface of the movable conical sleeve is provided with a split-type movable conical-tooth plate, and the grinding-base support sleeve is provided with a split-type grinding base with sieve holes. The external conical sleeve is connected into the upper external ring, and the split-type external conical-tooth plate is arranged in the external conical sleeve. The external circle of the upper case of the reducer is provided with more than three turnover roller assemblies comprising roller supports, roller shafts and rollers and arranged on the grinding base on the opening part of the transition ring. The shaft sleeve ray lid is provided with a feeding hopper and a guiding cap. Kick-out plates are arranged in the transition ring. In the whole crushing process, the force applying modes for rock-mine breaking dynamic properties, i.e. impacting, point pressing, breaking, cutting, laminating, and the like are simultaneously used, the ratio of crushing is high, and the effect of ultrafine crushing is obtained at one time.

Description

Technical field [0001] The invention relates to the technical field of rock ore crushing, in particular to an ultra-fine crushing technology for crushing large rock ore materials into fine particles at one time. technical background [0002] Existing crushing technologies include traditional equipment such as high-speed hammer crushers, impact crushers, compound crushers, cone crushers, and jaw crushers. Their crushing force method is single, and the crushing ratio is small, so that the rock ore crushing process must be completed by multiple processes of coarse crushing, medium crushing and fine crushing. In the technologies announced in ZL2004200100459, etc., although there is a large crushing ratio, it is still difficult to complete the ideal particle size requirement of beneficiation and grinding at one time. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a combined crusher. In the process of changing ...

Problems solved by technology

Their crushing force method is single, and the crushing ratio is small, so that the rock ore crushing process must be completed by coarse crushing, medium crushing, and fine crushing.

In the technologies published in ZL2004200100459, although there is a relatively large crushing ratio, it is still difficult to complete the ideal particle size requirement for beneficiation and grinding at one time.
