Description

Large tire recycling production line

technical field

Background technique

The development of modern society has led to an increasing demand for rubber products. After rubber products are discarded, they cannot be decomposed naturally, so they need to be recycled for reuse. At present, known waste tire recycling technologies are generally divided into two categories: one is chemical decomposition such as burning; the other is physical crushing such as rolling and cutting.

The disadvantage of the former is that it will cause serious environmental pollution, and the method of chemical decomposition has high technical requirements, high equipment cost, complex structure, and great difficulty in operation. In comparison, the latter is much easier to operate and implement, and the pollution to the environment is also much less, so the use of crushers for crushing has become a common practice in the tire recycling industry. At present, there are many crushers in the industry that can do the early stage, but almost none of them can complete the entire production line equipment. Many production lines are pieced together by purchasing various equipment separately, which leads to improper connection between various links, and the output and efficiency of each individual equipment do not match. Not only the energy consumption is high, but the recycling efficiency is also very low.
