Mineral crushing and grinding device

Abstract

The invention discloses a fine grinding device for ore, which comprises a casing, a hot oil chamber, a cylinder body, a grinding roller and a collection tank; the upper end of the outer side of the casing is covered with a hot oil chamber; The sleeve is provided with a first rotating rod; the first rotating rod penetrates through the bottom plate hinged on the inner side of the casing and is fixedly connected with the grinding roller, and the lower end of the grinding roller is correspondingly provided with a conical bottom; the inner bottom of the casing is also A collection tank is slidingly arranged, and the right end of the collection tank passes through the casing and is fixedly connected with the pull handle. The invention can heat the ore through the hot oil chamber provided, so as to facilitate the crushing and grinding of the ore, thereby improving the work efficiency; when the first rotating rod is moved downward, the four fan-shaped plates are driven to rotate downward by the pulling rod, so that the The cut ore falls down intermittently, realizing the effect of intermittent feeding, preventing too much ore from falling out of the stack, affecting the subsequent grinding effect, and has strong practicability.

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
