Micro-power mining machine capable of obtaining both high-quality river sand and multiple metal mineral powder

Abstract

The invention discloses a micro-power mining machine capable of obtaining both high-quality river sand and multiple metal mineral powder. The whole machine is formed by double layers of frames (4), wherein the upper-layer frame comprises a conveyor belt (2) covered with small draining holes or a sand passing tank formed by semi-circular solid grooves (19) as well as a stirring mechanism suspended above the sand passing tank; a mineral collecting tank (9) is fixed on the lower-layer frame; river sand particles smaller than the small draining holes and mineral powder included in the river sand drip with water drops into the mineral collecting tank (9) arranged below the conveyor belt, and then enter a sedimentation tank 16 from a mineral collecting tank gap 17 for treatment, medium sand (18) which is the larger-particle high-quality river sand reaches the tail end of the conveyor belt, so that the technical purpose of integrated mining including double obtaining by one-time power, national resources are saved, the production cost of a mining enterprise is reduced, and the economic value and social value are huge.

Description

technical field [0001] The invention relates to river sand mining equipment, in particular to a micro-power mining machine which combines high-quality river sand and various metal ore powders. Background technique [0002] River sand is an important building material, and the annual mining volume in the country reaches one trillion tons. River sand is rich in a variety of metal ore powders with a particle size of "mesh", including rare metals such as non-magnetic and weakly magnetic ilmenite, monazite, rutile and zircon, and strong magnetic common metal iron, etc. A variety of metal ore powder. These metal ore powders are mixed with river sand and deposited in the middle and lower layers of the river bed. They are in the same accumulation layer as the high-quality building material "medium sand" with a particle size of 0.35-0.5mm, and the particle size is less than 0.20-0.30mm. The best is fine sand, which has a low degree of coagulation with cement, less application and l...

Problems solved by technology

The applicant has proved by experiments that these machines can only be applied to the enriched ore with weak water flow, and if they are directly applied to river sand mining, they cannot be extracted due to the high water content of the ore, the lack of ore, and the rapid flow of water.
