Problems solved by technology

[0003] At present, the problem in the preparation of ultrafine powder is that the pulverized material will seriously wear the support body of the guide ring, and bring the worn iron into the product, which will affect the purity of the product; it is difficult to grind the mineral directly by mechanical grinding down to very fine particle sizes and with very high energy consumption

Embodiment Construction

[0010] The present invention will be further described in detail with specific embodiments in conjunction with the accompanying drawings.

[0011] An ultrafine titanium concentrate grinding process, which is mainly composed of a silo, a conveyor, a crusher, a mixer, a vertical mill, a powder separator and a dust removal device, and is characterized in that: The coarse ore is transported to the crusher by the belt conveyor to crush the mineral, and then enters the mixer, and at the same time adds a mixed grinding aid for stirring and mixing; then the mixed material is sent to the vertical mill for grinding, and the grinding time is corresponding Finally, the powder material is sent to the powder classifier, and the powder is screened, and the unqualified powder material is sent back to the vertical mill, and the process is repeated continuously. The qualified powder will be sent to the packaging machine for packaging, and finally produce ultra-fine mineral powder products.

Abstract

The invention discloses an ultrafine ilmenite concentrate grinding process flow, equipment is mainly composed of a cylindrical silo, a conveyer, a crusher, a mixer, a vertical mill machine, a powder selecting machine and a dust collector. The process flow is characterized in that crude ore in the cylindrical silo is conveyed to a crusher through a band conveyer for fragmenting the ore, then introducing in a mixer, simultaneously adding 0.5-0.8% of mixing grinding aid for stirring and mixing; then sending the mixing material in the vertical mill machine for grinding for a corresponding time, then sending the powder material to the powder selecting machine, screening the powder, if the power material is not qualified, sending to the vertical mill machine, and continuously repeating; screening the qualified powder material and sending into a packaging machine for packaging, and finally outputting the ultrafine ore powder products with size of 8-12mum.

Description

technical field [0001] The invention relates to a mineral ultrafine grinding process flow, which is an ultrafine grinding process flow for ultrafine processing (8-12um) of mineral materials into micron powders. It belongs to the technical field of processing and manufacturing. Background technique [0002] The ultra-fine grinding process mainly adopts the combination of mixed grinding aids and modern vertical mill grinding technology, and then processes and produces ultra-fine titanium concentrate powder through continuous process routes. At present, there are three main types of ultra-fine grinding (dry method) equipment: jet mill, high-speed mechanical impact mill and ball mill, which are generally produced by direct grinding. Vertical mill is a high-speed mechanical impact grinding method, which is used for mineral materials, chemical raw materials, medicines and health products. With the continuous development of the national economy, people's demand for titanium diox...
