Background

With the rapid development of the automobile industry in China, china has become the second largest tire producing country in the world, and the number of waste tires produced each year is over 1.12 hundred million and about 320 ten thousand tons. The method has the advantages that the method is fast in growth at a speed of two digits each year, the increasingly serious black pollution frosts the fragile ecological environment of China, meanwhile, the service life of the tire is limited, and discarded waste tires are infusible or refractory polymer elastomer materials, so that the tire has strong heat resistance, mechanical resistance and corrosion resistance, is extremely difficult to degrade, affects the ecological environment within one hundred years, and causes serious pollution. Such "black pollution" would pose a significant environmental hazard if not handled early.

Since the 70 s of the 20 th century, various countries in the world, particularly European and American countries, began to recover junked tires and attempted to develop scientific researches on the process of preparing fine rubber powder in order to effectively eliminate "black pollution". The fine rubber powder prepared from the waste tires can replace part of raw rubber, is a precious secondary resource, and is the best method for harmless, recycling and industrialization treatment of black pollution. The reclaimed rubber powder can be applied to the production of rubber products such as tires, and has wide market in the fields of highway, railway and subway sleeper heat, playground runway, leak-proof and seepage-proof materials, building materials, rubber and plastic products and the like paved by modified asphalt.

In China, the existing tire dicing flow is that firstly a tire side is cut off by a ring cutting machine, then the tire of the cut sidewall is cut into rubber strips with the length of about 5cm by a slitter, then the rubber strips are cut into rubber blocks with the length of 5cm square by a dicing machine, then the rubber blocks are ground in a rubber breaking machine, finally the rubber blocks are separated from fine steel wires and rubber powder in a magnetic separator, and finally the finished rubber powder is produced.

Above-mentioned dicing flow does not transversely flush cut the tire, and follow-up slitting, the dicing degree of difficulty is big to owing to do not have turning device, consequently need the manual work upset tire to come excision two sides wall, work efficiency is low, and has the potential safety hazard.
