Description

Rapid differentiation and fragmentation method for mine rock

Technical Field

The invention relates to a rapid differentiation and fragmentation method for mine rocks, and belongs to the technical field of mining mechanical equipment.

Background

In research and analysis of rock minerals or when rock minerals are used as test materials, it is sometimes necessary to manually process the mineral morphology, i.e. to break the rock minerals by striking them with a hammer. The above-described conventional means of striking a rock fragment using a hammer has significant drawbacks. Firstly, in the process of knocking and crushing, sharp mineral particles splash, so that experimenters have the risk of being injured; meanwhile, after the mineral particles fly out, the loss of the minerals is increased, and particularly, the splashing loss is not negligible when the mineral samples are precious.

In view of the safety risk and low efficiency of conventional crushing methods, there is currently no manual crushing device for rock minerals, and therefore a tool specially used for crushing rock mineral samples needs to be developed.

step two: placing the stone blocks in an extrusion area on the workbench, wherein the stone blocks are positioned in the enclosure;

step three: pressing down the pressing arm to enable the extrusion part to contact the stone block, observing whether two ends of the crushing arm are at the same height, if not, loosening the locking nut, rotating the screw rod, adjusting the height of the pin shaft until the direction of the action force of the extrusion part of the pressing arm relative to the stone block is vertical to the workbench, and finally screwing the locking nut;

step four: continuously pressing the pressing arm to make the extrusion part crack stones;

step five: then the pressing arm is lifted, and after primary fragmentation, the small crushed stones are taken out or swept to a hollow structure in an extrusion area and collected, and large stones are reserved;

step six: cleaning the inside of a crack of the sawtooth structure of the extrusion part of the fragmentation arm, and taking out stones;

step seven: and (4) performing secondary fragmentation, rotating the stone block by at least 90 degrees, and repeating the third step and the fourth step until all fragmentation is completed.

As a further preference, water is continuously sprayed on the stone during the disintegration.

As a further preferred option, the diameter of the dial is 1/2-1/4 of the length of the fragmentation arm.

As a further preferable scheme, the pressing part of the disintegration arm is of an arc-shaped structure, the arc-shaped concave surface of the pressing part faces downwards, and the pressing part is movably connected with the disintegration arm.

Compared with the prior art, the invention can be used for an ore mining field, can rapidly crack stones, is convenient to detect, improves the cracking effect, reduces manual operation, and is easier to control the cracking degree and the strength.
