Ore fine crushing and grinding device

Abstract

The invention discloses an ore fine crushing and grinding device which comprises a machine shell, a hot oil cavity, a cylinder block, a grinding roller and a collecting groove. The hot oil cavity is formed in the upper end of the outer side of the machine shell in a sleeved manner, a sleeve is rotationally connected to the upper end of the inner side of the machine shell, and a first rotating rodis arranged in the sleeve; the first rotating rod penetrates and is hinged to a base plate of the inner side of the shell to be fixedly connected with the grinding roller, and a taper bottom is correspondingly arranged at the lower end of the grinding roller; and the collecting groove is arranged in the bottom of the inner side of the machine shell in a sliding manner, and the right end of the collecting groove penetrates the machine shell and is fixedly connected with a pull handle. By means of the ore fine crushing and grinding device, the hot oil cavity is arranged so that ore can be heated, ore crushing and grinding are facilitated, and the working efficiency is improved; when the arranged first rotating rod downwards moves, four fan-shaped plates are driven by a pull rod to downwardsrotate, cur ore intermittently falls downwards, the intermittent discharging effect is achieved, falling and stacking of too much ore are prevented, the follow-up grinding effect is influenced, and the practicability is high.

Description

technical field [0001] The invention relates to the field of ore processing, in particular to an ore finely crushing and grinding device. Background technique [0002] Ore refers to mineral aggregates from which useful components can be extracted or which have certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. Minerals generally refer to all natural mineral or rock resources buried underground for human use. Human beings can extract many things from mineral products, such as gold, silver, iron, copper, etc., as well as some non-metallic materials and rock materials, but What is mined from minerals is not a certain substance, but a combination of various substances. When humans use these minerals, they need to classify, filter, purify, etc. to separate them into single substances, such as gold and iron, or can be The mixture used, such as limestone, the raw material of cement, needs to be crushed before these operati...

Minerals generally refer to all natural mineral or rock resources buried underground for human use. Human beings can extract many things from mineral products, such as gold, silver, iron, copper, etc., as well as some non-metallic materials and rock materials, but What is mined from minerals is not a certain substance, but a combination of various substances. When humans use these minerals, they need to classify, filter, purify, etc. to separate them into single substances, such as gold and iron, or can be The mixture used, such as limestone, the raw material of cement, needs to be crushed before these operations to turn it into fine particles, which improves the efficiency of subsequent operations and is also convenient for transportation and storage. The existing crushing device consumes energy High, low efficiency, not conducive to the processing and utilization of minerals, the existing ore fine grinding device can not effectively grind the ore, the grinding effect is poor, and cannot meet the expected requirements
