Crushing reusing system of waste milling material and process method thereof

Abstract

The invention relates to a crushing reusing system of waste milling materials and a process method thereof. The system of the invention comprises a feed hopper, a feeding belt, a feed-back belt, a composite grinding machine, a wind cooler, a cyclone dust collector, a material-collecting wind-out bag; the feed hopper is connected with the top of the composite grinding machine through the feeding belt; the side edge or bottom of the composite grinding machine is connected with the wind cooler through a pipeline; the discharge hole of the composite grinding machine is connected with the feed hopper through the feed-back belt; the side edge of the composite grinding machine is connected with the cyclone dust collector through a slantwise disposed wind-material pipe; the top of the cyclone dust collector is connected with the material-collecting wind-out bag through a pipeline. The invention can ensure the composition of asphalt is constant; the asphalt is recovered and reused, which has considerable benefits; the process is advanced; the structure is reasonable; the decomposition is clean; the recovery wrappage is uniform; the investment for the production is less; the usability is good; the system is multipurpose, and is applicable to both cold and hot materials; the materials are processed completely; no residual waste is left; and the production efficiency is high.

Description

technical field [0001] The invention relates to a system for crushing and reusing waste milling materials and a process method thereof. Background technique [0002] With the improvement of my country's economic situation, the mileage of high-grade highways has continued to increase, and a relatively complete highway and local road network has been built. Since 70% of the highways were built after the beginning of the new century, they have now entered the stage of repairing, In the renovation and overhaul stage, due to the unstable price of the international oil market, coupled with the limited development and utilization of domestic road raw materials, the cost of new construction and maintenance continues to rise, which is worth pondering by the transportation industry. [0003] It has been applied in road construction and maintenance. Although it has achieved certain results, there are several technical problems that have not been overcome. In addition, the production equ...

Problems solved by technology

[0003] It has been applied in road construction and maintenance. Although it has achieved certain results, there are several technical problems that have not been overcome. In addition, the production equipment cannot keep up with it, which has always troubled road repairers to make full use of the road surface milling material. Because of the fabric we all know: asphalt comes from imports, stone materials are hundreds of miles away, some places are transported to the construction site thousands of miles away, the technical indicators are high, and the local area may not be available, and alternative materials cannot be used (high price), if The processing technology can't keep up, which can only prevent the high-value surface material from being protected and utilized

[0004] At present, most of the highway milling materials in our country are mixed with stone and cement, or discarded directly, wasting asphalt. The main reason is that the processing technology and equipment cannot be matched.
