Description
Technical Field
The invention relates to the technical field of mineral separation, in particular to an integrated ore crushing and grinding device which is compact in structure, easy to operate, small in loss, good in crushing and grinding effect and high in efficiency.
Background
Crushing and grinding are the first step of fully dissociating useful minerals in ores from gangue, and are the first step of developing and utilizing mineral resources, and the first step is to provide materials with proper granularity for subsequent mineral processing operation. Because reasonable ore granularity is the key for improving the resource utilization rate, the grade and the recovery rate of the selected concentrate are lower because useful minerals and gangue are not fully dissociated, and because more fine particles which are difficult to sort are generated in the fine ore particles, the effective recovery is difficult to realize by adopting the traditional ore dressing method.
In the mineral dressing and metallurgy industry, the investment of ore crushing and grinding is the largest part of the whole dressing process, and the ore grinding accounts for a larger part of the whole dressing operation cost. Therefore, the method of 'more crushing and less grinding' and 'crushing instead of grinding' is always an important technical way for reducing the ore dressing cost and improving the separation efficiency of subsequent products, and reasonable crushing and grinding processes and equipment can directly influence the technical and economic indexes of ore dressing. Conventionally, the development and utilization of ore is that the ore is crushed, then ground and then further extracted through necessary screening, that is, the ore crushing, ore grinding and screening of the ore are separated, which not only results in a complex and bulky mechanical structure and high energy consumption, but also causes the ore to be transported through a transport machine between each equipment, thereby increasing the loss and the operation and maintenance costs, and the turnover transportation also causes noise and dust pollution. In addition, the existing ore crushing processing has the problem of unsatisfactory uniformity, large ore blocks still remain after crushing, the subsequent ore grinding operation is seriously influenced, and the main reason for realizing 'more crushing and less grinding, and replacing grinding with crushing' is also difficult to realize.
In the prior art, in order to solve the problems, a crushing roller is arranged on the upper part of the integrated box body to crush ores, the ores after primary crushing fall into the partition plate, the hydraulic cylinder horizontally arranged drives the push plate to enable the crushing teeth on the push plate to be matched with the crushing teeth on the fixed plate, and the ores on the partition plate are further extruded and crushed and then fall onto a screen with the fixed bottom to be screened and discharged. Although the crushing effect can be improved by the integrated two-stage crushing, the adverse effect of the large ore on the subsequent ore grinding operation can be avoided by screening, the operation efficiency of the extrusion crushing is low, the energy consumption is high, the problem of remaining large ore can be solved by the two-stage crushing and screening, the particle size of the ore cannot be effectively reduced, and a large amount of ore grinding operation is still needed for the subsequent process. A fixed crushing plate is fixedly arranged on one side of the box body, a plurality of movable crushing plates with different intervals are correspondingly arranged on the other side of the box body in a sliding manner from top to bottom, the movable crushing plates are driven to slide in a reciprocating manner, so that ores are gradually extruded and crushed from top to bottom, and a screening mechanism is fixed on the movable crushing plates to realize synchronous screening; and still move the fixed grinding plate in the bottom of crushing board to set up the sieve mesh on the box of grinding plate below, grinding plate reciprocating motion under the drive of moving the crushing board, the garrulous ore that makes upper portion screening back fall refines through reciprocal grinding, and the ore that refines that reaches the standard requirement at last falls through the sieve mesh whereabouts. The ore of the integrated device is subjected to step-by-step extrusion crushing, then is subjected to screening, grinding and rescreening, the uniformity of the ore can be effectively improved, and the particle size of the ore can be reduced, so that the workload of subsequent ore grinding can be reduced, but the reciprocating extrusion crushing efficiency is low, the power consumption is high, and in the reciprocating process, the large-particle-size ore which is not fully crushed at the upper part is easy to fall in the narrow extrusion gap at the lower part, so that the extrusion device is easy to block, and the production safety accident is formed. In addition, a gravity coarse crushing device capable of freely falling and moving is arranged at the upper part of the shell, and under the combined action of the lifting electromagnet and the pneumatic spring, the ore in the gravity coarse crushing device is hammered and coarsely crushed; then an extrusion grinding intermediate crushing device is arranged in the middle of the shell, so that the coarsely crushed ore entering the middle crushing device is rotationally extruded and crushed under the driving of a motor to form secondary crushing; then, a multi-section ball milling device and a screening device are arranged at the bottom of the shell, so that the ores after secondary crushing are subjected to multi-stage ball milling to form mineral powder or ore pulp meeting the requirements. Although the loss of the middle conveying link is reduced by the integrated structure, and the combination of the secondary crushing and the multi-section ball milling can effectively reduce the particle size after crushing and grinding and avoid safety accidents such as blocking, the gravity crushing efficiency of the gap type work is lower, the loss of energy conversion is increased by the separated power source, the integral structure is complicated, and the maintenance and the use are difficult.
