Processing system and method for compatible processing of natural material gravel and artificial hard rock and gravel

Abstract

The invention discloses a processing system and a processing method for compatible processing of a natural material gravel and artificial hard rock and gravel. The processing system comprises a stock bin, wherein a coarse crushing device is arranged below the stock bin, and matched with a first screening device; a medium crushing device is arranged behind the first screening device and matched with a second screening device; an ultra-crushing device is arranged behind the second screening device and matched with a third screening device; a rod mill is also arranged inside the processing system. By adopting the system and the method, two independent single-material source gravel systems, namely a land natural material gravel system and an artificial hard rock and gravel system are merged into a hard rock and gravel system and a natural material processing system, and can be compatible to treatment of two gravel materials. Staged production is adopted in a production form; screening equipment is designed according to the natural material when processing equipment is prepared, the crushing equipment is designed according to an artificial material, the maximal load demands are met, and flexible adjustment is carried out through a sealing-tape machine and a slide chute in the staged production, so as to adapt to the requirements of characteristics of different material sources.

Description

technical field [0001] The invention relates to a processing system and method for natural material sand and artificial hard rock sand, in particular to a processing system and method compatible with natural material sand and artificial hard rock sand. Background technique [0002] Concrete aggregate, as a resource-based industry, is facing the problem of resource reduction and depletion; fully rational and efficient use of resources is the focus of production. In the hydropower industry, the sources of concrete aggregates are diversified, including excavation materials, mining of natural sand and gravel materials, and mining of rock materials; in order to protect the environment (mining of rock materials involves re-cultivation and greening investment) and reduce costs, the economical sources of materials are: Excavation and utilization of materials, mining of natural sand and gravel materials, and mining of rock materials. However, the total amount of materials for excava...

Problems solved by technology

[0003] Usually, to deal with two different material sources, it is necessary to establish two independent single-source sandstone systems, namely the artificial sandstone system and the natural sandstone system. Ratio, determine the scale of the two processing systems, and then according to the characteristics of the material source, respectively select the process flow and equipment configuration, independent layout, the cost of the entire sand and gravel system is relatively large
