Waste type pulverizer and the rubber powder preparing process therewith

Abstract

The waste tire pulverizer includes waste tire inner ring cutting and separating machine, tire crushing machine, steel wire separating machine and waste tire rubber pulverizing machine. The rubber powder preparing process with waste tire includes: cutting and separating waste tire inner ring, crushing tire, separating steel wire and eliminating iron and crushing rubber. The rubber pulverizing machine is provided with wear-resistant high-hardness WC alloy cutters embedded in the inner conic surface of the conic stator and the outer conic surface of the conic rotor, and cooling water cavity in the conic stator and the conic rotor to control temperature raise, so that it can crush rubber into rubber powder of over 60-mesh fineness at normal temperature. The present invention has long service life, fine size of rubber powder, low power consumption and low cost.

Description

1. Technical field: [0001] The special pulverizing equipment for waste tires of the present invention is a special pulverizing equipment for making fine rubber powder by using the industrialized method of pulverizing waste tires at room temperature. 2. Background technology: [0002] Rubber is an important material for the production of tires and various rubber products. It is closely related to all fields of the national economy. my country is the second largest rubber country in the world and the third largest tire producer in the world. In 2001, it produced 100-300 million tires. With the rapid development of the global highway and automobile industry, the recycling and processing of waste tires known as "black pollution" has gradually become a major worldwide environmental protection problem. According to incomplete statistics, in 2001, the amount of waste tires produced in my country reached more than 5,000 10,000, but my country can only process about 26 million to 30 mi...

AI Technical Summary

Problems solved by technology

For a long time, the equipment used to produce rubber powder from waste rubber tires in my country mainly includes roller crushers. The crushing fineness can only reach 28 mesh at room temperature, and the output is low and energy consumption is large; waste tire rubber has high elasticity, High toughness, refractory polymer elastic material, difficult to crush at room temperature, developed countries use liquid ammonia CN 2 The cryogenic method is to crush waste rubber tires to the glass transition temperature and then crush them into rubber powder. Due to the high price of liquid nitrogen, it is economically uneconomical to produce waste tires with low added value and is not suitable for China’s national conditions.
