Ore refers to a collection of minerals from which useful components can be extracted or which themselves have some property that can be exploited. Can be classified into metallic minerals and nonmetallic minerals. The unit content of useful components (elements or minerals) in the ore is called ore grade, precious metal ores such as gold, platinum and the like are expressed in grams/ton, and other ores are commonly expressed in percentages.

The prior art has the following problems:

the crushing equipment of ores is quite complete at present, most of the crushing equipment has high pressure and high crushing performance, huge ore blocks can be crushed at one time, but the crushing equipment is almost designed for original ore blocks in mining, and when geological exploration is carried out, the crushing requirements of the ores are different, some ores with small volumes are required to be crushed further, if a mine crusher is directly adopted for crushing, the efficiency is definitely very high, but the crushing equipment is not applicable, smaller ores are difficult to be crushed sufficiently, the amount of ore is small after all, the volume is small, and the ores can hardly be leaked out of the equipment by sufficient extrusion contact in a crusher with large size. For the operation of directly adopting the vertical downward pressing of the hydraulic cylinder, the ore can be fully contacted with the hydraulic column, but the main effect is still the crushing effect, but not the crushing effect, the huge forward downward pressure is instantaneously pressed down, the ore is easy to splash, or the ore is directly cracked to be a few flaps and then flies out, and the full crushing effect is also not obtained.

For this reason, we propose a ore step-by-step reducing mechanism to solve above-mentioned drawback.
