Jiangyin Netzsch waste tire automatic processing line has passed the expert evaluation

The Nez automatic program-controlled waste tire processing production line developed by Jiangyin Netzsch Machinery Technology Co., Ltd. (Jiangyin Xinda Pharmaceutical Machinery Manufacturing Co., Ltd.) has small installed capacity, high automation, small floor area, low investment and low operation cost. The whole production line requires no manual operation in the middle section except at both ends, It truly realizes automatic intelligent control. On August 26, the production line passed the expert evaluation organized by the waste rubber comprehensive utilization branch of China Rubber Industry Association

according to Gu Jun, deputy general manager of Jiangyin Netzsch, the production line adopts 42 patented technologies of independent innovation and domestic advanced layered tooling for design, which realizes the microcomputer automatic program monitoring of the whole production process. The whole production line can be controlled by a one button switch, and the temperature, water pressure, current, feeding speed, operating intensity, output, discharging fineness of each part of the production line can be intelligently controlled and automatically adjusted The material level of each equipment silo and the operation of each equipment

caoqingxin, Secretary General of the waste rubber comprehensive utilization branch of China Rubber Industry Association, introduced that in 2010, China's waste tire production was about 256 million, weighing 9.4 million tons, of which 3 million tons of recycled rubber and rubber powder were produced, accounting for about 80% of the total utilization of waste rubber. The crushing of waste tires is the first step in the production of rubber powder and reclaimed rubber. Its function is to separate the steel wire, fiber and other materials in waste tires from rubber, so as to maximize the value. Therefore, the treatment of waste tires is very critical. With the continuous improvement of raw materials, energy and labor costs, enterprises urgently need energy-saving and emission reduction equipment to realize production automation and efficiency, and the automatic program-controlled waste tire treatment production line developed by Jiangyin Netzsch just meets this demand

this production line has two innovative features: first, the whole tire crusher cutter is changed from integral type to detachable type. At present, the surfacing alloy blade used in the industry needs to disassemble the whole equipment after wear, take out the blade, re surfacing the alloy, and then polish and assemble. Now it is changed to a detachable cemented carbide blade, which can quickly and easily replace the tool on the equipment, thus solving the problems of difficult replacement, difficult repair and high cost after the cutter head is worn, and shortening the time to repair or replace a set of blades from dozens of days to half a day, It greatly improves the efficiency of the equipment. Second, the rubber block rubbing and cutting machine adopts the working principle of rotary grinding and cutting to form a 360 degree effective working surface, which solves the shortcomings of the currently used double roller crusher and rotary blade crusher, such as high energy consumption, low efficiency, fast blade wear, etc. The inner sleeve and the grinding and cutting surface of the spiral shaft in the equipment are made of cemented carbide materials, and the grinding and cutting surface at the front end of the spiral shaft adopts a detachable structure, which can be quickly replaced, greatly reducing the operating cost of users

in addition, the production line also changed single hook single-sided wire drawing to double hook double-sided simultaneous wire drawing, and changed hydraulic transmission to mechanical transmission, which is fast and efficient. It can quickly pull out the steel wires on both sides of the tire at the same time, which is 3 times the processing capacity of single hook wire drawing; The rubber powder screen adopts a vibrating motor, which changes the way that the rubber powder screen motor drives the connecting rod, solves the shortcomings of the connecting rod powder screen, such as low vibration frequency, easy damage, low powder yield, and plays the role of conveying rubber particles, removing steel wires, removing and replacing the solvent based process with water-based process to complete the surface treatment fiber of the cushion track and classifying rubber powder. It has the characteristics of high screening accuracy, large processing capacity, high efficiency, small overall floor area, etc; The belt type iron remover adopts electromagnetic module to remove steel wires, which solves the shortcomings of permanent magnet iron removal, such as small magnetic force, low penetration, and unadjustable magnetic force; The fine crusher adopts horizontal flat grinding structure, and the grinding disc body is made of special wear-resistant materials formed at one time, which has the advantages of impact resistance, good toughness, long service life and so on. The horizontal integral structure makes the structure with water in the oil, and also solves the problems of poor installation accuracy of the split structure, compact structure, large vibration, inconvenient maintenance and so on

it is understood that Nez automatic program-controlled waste tire treatment production line has obtained 10 national patents for PU foaming materials with low shrinkage, high elasticity and skid resistance. The tire crusher of the main machine of the production line adopts two motors with an installed power of 90 kW. The energy consumption of the production line from crushing waste tires to producing 60 mesh fine rubber powder is only about 380 kwh/ton, and the energy consumption of producing 40 mesh rubber powder is 320 kwh/ton, which is about 31% and 24% lower than the current industry average energy consumption respectively; The output is increased by more than 30%, and the production capacity can reach 50000 ~ 100000 tons/year according to the configuration. In addition, the hardness of its cemented carbide tools is more than 62 degrees, and the service life is more than 3000 hours, while the service life of foreign tools is generally about 1000 hours. Users reported that the production line has been used for more than a year, and the effect is very satisfactory. Compared with similar equipment at home and abroad, it greatly reduces the investment and operating costs. At present, dozens of the production lines have been successfully promoted and exported to the United States, Japan, Russia, Ukraine, Syria, South Africa, Spain, Turkey, Saudi Arabia, Mexico, Iran, India, Slovenia, Sri Lanka and other countries

the evaluation experts agree that the goal of this project is "Build and test whether the space structure is suitable for the use of spacecraft. The cutting tool of the production line is removable, the hardness design is reasonable, and innovative; compared with similar foreign products, the equipment has a novel wire rolling structure, the separation of steel wire and rubber is relatively complete, and the separation effect of rubber powder reaches more than 95% at 5 ~ 8 mesh; the linkage automation program is reasonable, the conveyor is silent, and the microcomputer operation and unit control are realized; the production line is suitable for 60 ~ 12 mesh The production of 0 mesh rubber powder has been tested by Jiangsu Institute of product quality supervision and inspection, and the product meets the index requirements of gb/t vulcanized rubber powder; The production line adopts the physical method of crushing waste tires at room temperature, without the emission of "three wastes", and the noise of the working face is low. The measured value is 75 dB
