◆ With the increasing number of used tires in the car, many people have followed the market for waste tire rubber recycling, and used the waste rubber tire mill to start a business of recycling and recycling used tires. According to statistics, the world produces 35 million tons of waste tires per year, but the recovery rate is less than 5%. Waste tires are toxic and harmful solid wastes, have strong heat resistance and degradation resistance, and will not degrade after being buried in the ground for 100 years. Recycled used tires can be ground into rubber powder. After being recycled into recycled rubber, they can be used in the manufacture of plastic flooring, plastic runway and other industries. If they are added to natural rubber in proportion, they can be used to make new tires.
◆ The key problem of recycling waste tire milling technology is the crushing of rubber; the second is the treatment of the radial tire with steel wire, that is how to separate the steel wire from the rubber compound. From the liquid nitrogen freezing method first introduced by the Americans to the air freezing method, the problem of the normal temperature method created in China was solved, and the treatment technology of the oblique rubber tire was solved. However, the treatment of radial tires is the key issue. The normal temperature method waste rubber grinding powder machine production line is a technical equipment for treating waste radial tires by physical method. The rubber mill processes the waste rubber waste tire into a fine rubber powder which can be recycled.
