Embodiment Construction
[0022] Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0023] figure 1 It shows the mechanism connection diagram of the comprehensive processing method of ore material according to the present invention. refer to figure 1 , the raw ore is pre-selected and passed through the jaw crusher (hereinafter referred to as "jaw crusher") and crushed into small pieces below 25 mm, and the small pieces after jaw crushing are put into the joint operation of ball crusher 10 and dry cleaning machine 20 for crushing Separate from the sand powder, send the sand material with a particle size of 6 to 120 mesh after removing the fine powder into a closed vibrating sieve to sieve into various types of quartz sand, and return the oversized particles remaining after the sieve to the ball crusher 10 for further crushing. The fine powder separated by the dry cleaning machine 20 is sent to the ball mill classification syste...

Abstract
The invention provides a comprehensive processing method for a mineral aggregate. The method comprises the steps of: feeding small lump materials crushed by a jaw crusher into a ball breaker to pulverize, and forming a sand powder mixing state; feeding the sand powder mixture into a dryer to carry out sand and powder separation; feeding sands with 6-120 meshes from which fine powder is removed in the dryer to a sealed vibrating screen to screen various types of ore sand; returning residual ultra-large particles to the ball breaker to pulverize; feeding the fine powder separated from the sand powder by the dryer to a ball-milling grading system and processing into silica powder with 120-325 meshes, and then collecting the fine powder which is more than 325 meshes as ultra-fine powder by a pulse dust remover. By adopting the comprehensive processing method disclosed by the invention, ore products which have three stages of the sand, the micro-powder and the ultra-fine powder and various specifications can be produced from a mine at the same time; production without indirect materials can be achieved; the overall operation is carried out by a full-dry method under negative pressure; no dust emits; no water pollution generates, and no over-crushing phenomenon appears, so that the purposes of saving the material and energy and protecting the environment are achieved.
Description
technical field [0001] The invention relates to a processing method of mineral material, in particular to a comprehensive processing method of non-metallic mineral material. Background technique [0002] Quartz is a mineral resource with very stable physical and chemical properties. It has the characteristics of high mechanical strength, strong pollution interception ability, and good acid resistance. As a hard, wear-resistant, and chemically stable silicate mineral, it is widely used. Used in optics, glass, electronics, chemical and refractory industries. The existing quartz processing methods mainly include dry processing and wet processing. However, dry processing can only be designed for a single coarse crushing or fine crushing, and it is impossible to achieve a unified production line to produce finished products of various finenesses. There is a single product variety, which will produce more side materials, low ore utilization, high energy consumption, dust pollutio...
