High-efficiency circulation rubber grinder

Abstract

The invention discloses a high-efficiency circulation rubber grinder. The high-efficiency circulation rubber grinder comprises a feed mechanism and a first grinding chamber. A first grinding set comprises a fixed grinding disc and a movable grinding disc. The discharge end of the feed mechanism communicates with an opening in the fixed grinding disc. The movable grinding disc is connected with a first motor through a horizontal spindle. The feed mechanism comprises a spiral feed pipe and a speed adjusting motor. The spiral feed pipe is provided with a feed hopper. A crushing impeller set is arranged above the feed hopper. A vertically arranged grinding roller is arranged below the first grinding set. An obliquely arranged screening net is arranged between the grinding roller and the fixed grinding disc. A second grinding set is arranged in a second grinding chamber. A spiral feed pipe is connected to the bottom of the second grinding chamber. According to the rubber grinder, the grinding efficiency and the quality of rubber powder are improved, and the service life of equipment is prolonged, meanwhile, large particles left on the screening net can be automatically cycled and ground repeatedly, and the work efficiency and powder quality are further improved.

Description

technical field [0001] The invention relates to the technical field of production machinery, in particular to a high-efficiency circulating rubber grinder. Background technique [0002] The rubber industry occupies a very important position in the national economy. The rubber produced by the rubber industry is an important strategic substance. It is widely used in people's daily life and in the field of national defense and military industry, but its waste is also a source of environmental pollution. one. At present, a large number of waste rubber products are produced every year, including non-tire rubber products and tires. These waste rubber products need to be disposed of, and the disposal of these wastes can neither pollute the environment, but also can be recycled and reused. This is the common practice of all countries in the world today. the goal that is pursued. Recycling and processing of waste rubber products such as automobile tires and shoe soles requires that...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that steel wires still remain in the rubber. If these steel wires enter the grinding machine, they will inevitably cause damage to the grinding disc and affect its life, and if the particles entering the grinding machine are too large, it will also increase the wear of the grinding disc. The burden will cause damage to the equipment. At the same time, the traditional grinding machine adopts a single grinding method, the powder particle size is not uniform enough, the quality of the rubber powder produced is not high, and the grinding efficiency is low. The multi-stage crushing and grinding of rubber particles prevents the steel wire from entering the grinding disc and causing damage to the equipment, improves the grinding efficiency, the quality of the rubber powder and the service life of the equipment, and at the same time can remove the large particles left in the sieve. Automatic cycle for multiple grinding, instead of manually collecting the residual material on the sieving net and then grinding, which further improves the work efficiency and the quality of the powder
