Stone multi-stage smashing device for ore mining

Abstract

The invention discloses a stone multi-stage smashing device for ore mining. The stone multi-stage smashing device for ore mining comprises a shell, a filler opening, a screen, a drive motor and smashing rollers. Multiple limiting rollers are horizontally distributed in the filler opening. The horizontal screen is fixed to the upper portion in the shell. A vertical extrusion plate is arranged abovethe screen, and multiple horizontal magnetic bars are fixed to the circumference of a rotary disc. The two cooperated smashing rollers are arranged under a discharge pipe, a horizontal moving plate horizontally penetrating out of the two sides of the shell through openings is arranged below the smashing rollers, and vertical pushing plates are fixed to the portions, located on the outer sides ofthe two smashing rollers, of the horizontal moving plate. Stones entering the device are preliminarily smashed through the extrusion plate moving left and right, the stones which cannot fall are continuously smashed, and complete smashing is guaranteed; and through the rotating magnetic bars, iron is removed out of the stones, it is guaranteed that following fine treatment of the stones is safer,and damage to equipment is reduced.

Description

Technical field [0001] The invention relates to the field of ore mining, in particular to a multi-stage crushing device using stone materials for ore development. Background technique [0002] With the continuous development of the mining industry, ore will be divided into different grades according to different parameters such as particle size and composition. In particular, particle size is an important criterion for measuring ore; too large or too small particles affect the price of ore, and slag Materials such as ore and ore are frequently used building materials in the construction process, but ordinary stone is generally larger in size and does not meet the requirements of building stone. [0003] At present, the ore with too large particles needs to be crushed into smaller ore and sieved. At present, workers generally use a hammer to slowly crush the larger ore and manually screen it. This requires a lot of Manpower, there is often insufficient fragmentation when broken, an...

Problems solved by technology

[0002] With the continuous development of the mining industry, the ore from mining will be divided into different grades according to different parameters such as particle size and composition, especially the particle size is an important criterion for measuring ore; too large or too small particles will affect the price of ore, and slag , ore and other materials are frequently used building materials in the construction process, but ordinary stones are generally large in size and do not meet the requirements of building stones

[0003] At present, ore with too large particles needs to be crushed into smaller ores and screened. Currently, workers generally use hammers to slowly crush larger ores and manually screen them. This requires a lot of Manpower, there is often insufficient crushing when crushing, and the work efficiency is low
