Damping type ore coarse crushing device for mining machining

Abstract

The invention discloses a damping type ore coarse crushing device for mining machining. The damping type ore coarse crushing device for mining machining comprises an operation frame. A crushing grooveis arranged in the operation frame. A sliding frame is arranged on a limiting and guiding slide groove in a sliding manner. A transmission belt is arranged between a driven belt pulley and a drive belt pulley in a sleeving manner. A hoisting frame connected with an L-shaped bent rod in a sliding manner is vertically and fixedly installed on the operation frame. A rack is fixedly installed on thelower bottom face of the L-shaped bent rod. According to the damping type ore coarse crushing device for mining machining, through vertical reciprocating movement of a sliding rod, an impacting pressblock is driven to conduct repeated impaction crushing action on ores in a crushing groove, in the impaction crushing process, supporting legs can slide in limiting sleeves, deformation elongation andcompression of damping springs achieve the damping function, and therefore the stability of ore crushing is improved; and left-right reciprocating movement of the crushing groove drives the ores in the crushing groove to shake left and right, the ores are promoted to be evenly laid and scattered in the crushing groove, the ores can receive the sufficient crushing action of the impacting press block, and therefore the crushing efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of mining processing, in particular to a shock-absorbing ore coarse crushing device for mining processing. Background technique [0002] Ore refers to the mineral aggregate mined from the ore body, from which useful component elements, compounds or minerals can be extracted. It is formed in various geological mineralization processes, and the ores formed by different geological mineralization processes have different Under the conditions of modern technology and economy, metals or other products can be processed and extracted from minerals on an industrial scale. The ratio of the useful component elements in the ore or the weight of the mineral to the weight of the ore is called the ore grade. Gold, platinum and other precious metal ores are used in grams / ton means that other ores are usually expressed as a percentage, and the ore grade is often used to measure the value of ore. The composition of ore and ...

Problems solved by technology

[0003] Preliminary crushing treatment is required before the ore is finely processed, so as to realize the crushing of large ore and refine it into small ore fragments, which is convenient for subsequent screening and fine processing. The current ore crushing device has a crushing effect on ore Not good, the crushing efficiency is low, large ore cannot be fully crushed, and the vibration that is easily generated during the crushing process can easily affect the stability of the crushing device, thereby affecting the effect of primary crushing of ore
