Heating and crushing processing system for waste rock solids in coal mining

Abstract

The invention provides a heating and crushing processing system for waste rock solids in coal mining. The eating and crushing processing system comprises a calcinator, a calcining mechanism, a slidingplate, an electric push rod, a crushing box, a crushing mechanism and a supporting frame. The heating and crushing processing system can solve the following problems existing in the process of crushing and processing the waste rock solids in a coal mine: a, for coal mine waste rock crushing modes, in a traditional process, the coal mine waste rocks are conveyed into a crusher for stirring and rolling and decomposed into recyclable fine particles, no crushing pretreatment is conducted on the coal mine waste rocks in the traditional process, and it is difficult for the crusher to roll the coalmine waste rocks into small pieces; and b, generally, a traditional crusher is used for crushing the coal mine waste rocks, in this way, it is difficult to ensure that the coal mine waste rocks are 100% broken into required small pieces, the traditional crusher has low use efficiency and high labor cost, and it is often necessary to carry out secondary crushing on the broken waste rocks to ensurethat the broken small pieces can be used.

Description

technical field [0001] The invention relates to the field of coal mining and processing, in particular to a heating and crushing processing system for coal mining waste rock solids. Background technique [0002] Waste rock refers to the general term for the surrounding rocks and rocks that have been mined without ore. In the open-pit mining field, the stripped overburden, surrounding rocks and gangsters without industrial value are collectively called waste rocks. These waste rocks must be removed in time. Discarded to a certain location, the place that can accommodate waste rocks is called a waste rock yard. Waste rocks are resources that have been misplaced. Waste rocks are not completely useless. The pushing of a large number of waste rocks occupies land area. If things go on like this, the harmful Substances will pollute the air and soil, and pose a threat to people's health, but waste rock can be "turned into treasure" after processing, and has multiple uses in the mini...

AI Technical Summary

Problems solved by technology

[0003] At present, the following problems exist in the crushing process of coal mine waste rock solids: a. For the coal mine waste rock crushing method, in the traditional process, the coal mine waste rock is transported into the crusher for stirring and rolling, so that it can be decomposed into recyclable The traditional process does not carry out pre-crushing treatment of coal mine waste rocks, which makes it difficult for the crusher to crush them into fine pieces. b. Traditionally crushed coal mine waste rocks are generally crushed by crushers, so it is difficult to ensure that the coal mine waste rocks It is 100% broken into the required fine pieces, which makes the utilization efficiency of traditional crushers low and the cost of labor is high. It is often necessary to crush the waste rocks that have been crushed to ensure that the broken small pieces can be used.
