Abstract

The invention discloses a combined super-fine crusher. The combined super-fine crusher comprises a speed reducer, a vertically arranged main shaft, an upper jacket, an outer taper sleeve, a movable taper sleeve and a grinding base support sleeve, wherein a power output end of the speed reducer is in transmission connection with the main shaft; the movable taper sleeve and the grinding base support sleeve are in key connection with the main shaft from top to bottom respectively; the upper jacket is arranged outside the outer taper sleeve; the outer side of the movable taper sleeve is provided with a movable conical tooth plate; the inner side of the outer taper sleeve is provided with an outer conical tooth plate; an annular crushing cavity with a wide top and a narrow bottom is formed between the movable conical tooth plate and the outer conical tooth plate; the outer side of the grinding base support sleeve is provided with a grinding base provided with sieve pores; and a grinding device is arranged above the grinding base. The combined super-fine crusher finishes crushing in a plurality of stages according to a brand new design concept, applies forces according to different types, selects materials according to the forces, realizes controllable low speed and completes thick, medium, fine and super-fine crushing in one machine. The combined super-fine crusher has the characteristics of high energy efficiency, low abrasion wear, vibration-free property, low noise and remarkable social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of rock and mineral crushing, and in particular relates to a combined ultrafine crusher for crushing large rock or mineral materials into fine particles at one time. Background technique [0002] Rock ore crushing technology equipment is common equipment in many basic industries in the national economy, covering metallurgy, mineral processing, building materials, coal, thermal power, chemical industry, non-metallic mineral processing and new materials and many other industries. There are tens of billions of tons of rock and mineral materials that need to be crushed every year in the country. The total power consumption of various industries for crushing operations has accounted for more than 5% of the country's total power generation. Therefore, energy saving and consumption reduction in crushing operations are of great significance to the national economy. [0003] Existing crushers for rock and mineral m...
