Abstract

The invention provides a preparation method for a high fine rubber powder and a production line thereof. The preparation method for the high fine rubber powder prepared by using waste rubber comprises of smashing and resolving the waste rubber; and rolling the waste rubber after being smashed and resolved so as to obtain coarse rubber powder; milling and then accurate grinding the coarse rubber powder, so as to obtain fine rubber powder; refrigeration rubbing the fine rubber powder, so as to obtain high fine rubber powder. Wherein, milling and accurate grinding are conducted at room temperature and refrigeration rubbing is conducted at the brittle temperature of rubber. The preparation method for high fine rubber powder and production line thereof provides a production line for preparing high fine rubber powder by using waste rubber. The production line comprises smashing system, granulation system, milling and accurate grinding system and refrigeration rubbing system. Wherein, the milling and accurate grinding are conducted at room temperature and the refrigeration rubbing is conducted at the brittle temperature of rubber.

Description

technical field [0001] The invention belongs to the field of waste rubber recycling and reuse, and mainly relates to a preparation method of high-fine rubber powder and a production line thereof. Specifically, it relates to a method and a production line for producing high-fine rubber powder in an environment where normal temperature grinding and freezing grinding are integrated. Background technique [0002] Waste rubber contains abundant raw material resources. During the pre-cooling process, for example rubber from scrap tires should be crushed in a brittle state and converted into a secondary raw material that can be used again and returned to the production process. Used car tires and industrial rubber product waste are also rich sources of raw materials. Also, the continued growth in the amount of such waste and waste material poses a considerable burden on the environment. Under the principle of recycling economy and in order to reduce the emission of carbon dioxid...
