Hydraulically-loaded dual-power pulverizer

Abstract

The invention discloses a hydraulically-loaded dual-power pulverizer which comprises a body, a large pulverizing disc arranged in the body, a pulverizing disc power device for driving the large pulverizing disc, and pulverizing head bodies matched with the large pulverizing disc, wherein the pulverizing head bodies are arranged on saddles. The pulverizer also comprises a pulverizing head power mechanism for driving the pulverizing head bodies, a charging device arranged on the upper part of the body, and an air inlet system and an overflow recovery device which are arranged at the bottom of the body, wherein the front ends of swinging arm bodies are rigidly connected with the pulverizing head bodies through pin shafts, screws and fixing keys; pulverizing head rollers are pressed to the inner side of the steep wall of the outer edge of the large pulverizing disc under the action of hydraulic devices; the tail ends of the swinging arm bodies are connected with a tail frame through rotating wheel shafts, so that the swinging arm bodies can rotate around the rotating wheel shafts, respectively; lubricating oil circulation systems are used for pulverizing head spindles. The whole pulverizer can stably run, and is slight in vibration, easy to maintain and high in efficiency.

Description

technical field

[0001] The invention relates to a micropowder vertical roller cutting mill, in particular to a hydraulic-loaded dual-power mill. Background technique

[0002] The structure of the known mills is mostly that the large grinding disc rotates around the central axis, the central axis is driven by the lower motor and the reducer, the grinding head and grinding roller are driven by the large grinding disc to rotate around their own axis, and the grinding head and grinding roller have no power , when this vertical roller mill is working, the effect of the grinding roller and the large grinding disc on the material is mainly to grind the material into powder by extrusion. Chinese patent vertical roller mill, application number 02258005.0, is a spring-loaded dual-power grinding and milling equipment, including the body, the large grinding disc in the lower body and its power transmission mechanism, and two to five evenly distributed and large grinding discs.
