Recycling of radial tires and HGM higher-finess carbon black grinding mill

Author : Clirik

 The international code for radial tires is "R", commonly known as "steel tires." The fundamental difference between radial tires and biased tires is the carcass. The carcass is the foundation of the tire, which is a layer-by-layer structure composed of cords. The carcass of the skewer tire is the ply of the skew line fork; the carcass cord of the radial tire is side by side, and the top layer of the carcass often contains a steel strip made of steel wire. The angle between the arrangement of the cords and the meridian section of the tire is zero. (ie the angle to the tread centerline is 90.). This arrangement of cords is much like the meridian of the earth (ie, the warp), so it is called the radial tire. This arrangement of cords allows the strength of the cord to be fully utilized and utilized, so the number of layers of radial tire cords is generally 40% to 50% less than that of ordinary bias tires, generally only 1-4 layers, and steel radial tires are generally only A layer of ply. Only the rubber is used between the cords to maintain the circumferential direction. In order to withstand the large tangential force generated during driving, the radial tire adopts multiple layers and large angles (the angle with the meridian section is 〖70〗^°-〖75〗^°), high strength, not easy to stretch A buffer-like belt (also called a hard buffer layer or a tightening layer) is used to reinforce the crown, just like a rigid loop, which is fastened to the tire. The meridian tire has a wide cross section, and the aspect ratio (H/B) of the cross section is about 0.7.
Radial tire production requires the use of new process carbon black varieties with better performance, stable quality and wet granulation. Such as N115, N121, N234, N375, N326, N330, N550, N660, etc., due to the widespread promotion of 10,000-ton new process carbon black production technology, wet granulation products have reached more than 70%, basically satisfying radial tires. The need for rapid development of production.
Tire retreading, also known as tire remanufacturing, is the first choice for tire recycling. With modern refurbishment technology, the life of a retreaded tire can be equal to that of a new tire. Good retread tires, life expectancy can exceed 25%~45% of new tires (pre-cured treads are pressed separately, the pressure can be 1 times higher, so it is more wear-resistant).
HGM carbon black grinding mill can make the recycling tire transformed into higher-fineness carbon black, so as to enlarge its application area. More information of this machine can be found on our website.
Our company is a manufacturer of carbon black grinding mills which can grind carbon black into powder with different fineness. If you are interested in our machine, you can contact us at any time. You can chat with us online or leaving messages on our website.
