Direct pulverzing mill of glass fiber reinforced plastic wastes

Abstract

The invention belongs to the technical field of pulverzing mills and particularly relates to a direct pulverzing mill of glass fiber reinforced plastic wastes. The direct pulverzing mill comprises a main motor, a speed reducer, a milling disc, a clamping frame, a pressing head and a rapid going-forward / going-backward disc, which are mounted in a rack, wherein the main motor is connected with the speed reducer; the main motor and the speed reducer are mounted at the lower part of the rack; the speed reducer drives the milling disc; a milling piece is mounted in the milling disc; the clamping frame is arranged above the milling piece; the pressing head is mounted on the clamping frame; the rapid going-forward / going-backward disc drives the pressing head; the pressing head can move in the clamping frame; and the direct pulverzing mill is characterized in that the milling piece is a steel-based milling piece plated with carborundum and spiral convex edges are fully distributed on the milling piece; and the milling disc is internally provided with a cooling water pipe, is provided with a main motor cooling water jacket and is equipped with a dust separation cover. The direct pulverzing mill of the glass fiber reinforced plastic wastes has a large milling region and has a good milling effect on the glass fiber reinforced plastic wastes.

Description

technical field [0001] The invention relates to a pulverizer, especially a kind of direct pulverizer for FRP wastes smaller than large particle size (any shape as long as the particle size is below 250X180X60). Background technique [0002] FRP products have been widely used. According to the statistics of China FRP Industry Association, by 2007, the total output of FRP in my country exceeded 2.7 million tons, and its consumption is still growing rapidly every year, but it also has the disadvantages of not being easy to degrade, decompose and recycle. On the one hand, in metallurgical and chemical enterprises, a large number of FRP products are used, and with the expiration of service life and maintenance and replacement, a large amount of FRP waste is generated; on the other hand, a large amount of scraps are also generated in the production and construction of FRP products . Some of these wastes stick to harmful heavy metals, chemical mixtures, etc., and cannot be piled ...
