Configuration and process of ore milling equipment for ore dressing

October 24, 2017 by onlysunny  

The ore milling equipment needs to be used in conjunction with other equipment to form an ore dressing production line. The Ore Milling Equipment is an important component of the mineral processing production line. It is a necessary procedure to improve the grade of mineral material by using ore mill. The application value of concentrate and the selection of impurities in ore can improve the utilization ratio of mineral material and obtain higher economic value.

According to the characteristics of mineral material, choose magnetic separation or flotation method for mineral processing, if the mineral material does not contain leaves, mud, dirt, residues and other debris, only the magnetic separation function to select the concentrate. In general, in order to improve the aggregate grade better, the crusher, mill mine, spiral separator, flotation machine, magnetic separator is the key equipment for processing, other auxiliary equipment like feeder, screening machine, conveyor are also essential.

According to the characteristics of mineral materials, choose magnetic separation or flotation method for mineral processing, no matter what kind of choice, the production process is indispensable mine grinding machine.

The broken ground plus: the use of large stone crusher will be broken into small particles, can be used fine crushing processing combined, broken more fully, and then use the mine beneficiation mill for grinding after ore fines mine mill grinding into the next process.

Grading: need to use spiral pole machine classification program, using spiral classifier aggregate gravity size was graded aggregate, sorting out concentrate, spiral pole can be separated in the aggregate debris, to classify the aggregate.

Magnetic separator: magnetic separator uses magnetic force to separate the magnetic impurities in the mineral material. The magnetic separator makes a preliminary classification of the ore material, and then it is sent to the flotation machine for flotation processing.

Flotation machine: material plus flotation reagent into the flotation machine, making the minerals to be separated with other substances, after using the wet material of thickener initial concentration, drying, concentrate can be obtained.

New development of mineral grinding technology

October 23, 2017 by onlysunny  

Grinding of ore and other materials more finely, can make production more efficient, can save a lot of cost, and can make tailings recovery processing become simple. The fineness of grinding and discharging products discussed here refers to the P80 granularity of 20 m and 7 m, which needs to be produced in the production line of energy cost and low cost mill. If you want to reach the fineness, in the production line equipment selection, the general selection of ultrafine Ore Milling Equipment as the main milling equipment, mineral particle monomer dissociation required electric energy consumption accounted for about 70% of the total cost of mineral processing plant, in the application of conventional milling equipment will grind mineral size to 2020 m below, the traditional in ultrafine grinding when the cost of grinding and grinding fineness decreases with increasing exponential function.

A problem with the traditional grinding fine grinding mill is the mineral speed is relatively low, because when the mill speed is higher than the critical speed, the grinding medium by centrifugal force together with the rotary cylinder, power low speed mill is relatively low, in fine grinding, grinding and high processing capacity required for low power intensity mill can not meet the mineral industry, it must increase the equipment, which in turn increases the production cost, in order to solve these problems, need to use the traditional mill diameter greater than 20mm steel ball, the steel ball gap so large is great, the fineness of grinding in small particles of 2020 m is too large, the material of small the magic ball impact and grinding pressure can not form a fine effect, but increase the magic wear rate, make the production line to produce a large number of substandard products. Therefore, the traditional mill in the high demand of production requirements, appear more and more no ability, production contradiction is also urgent need to solve.

Based on this, brought the dawn of birth of new ore milling equipment for ultra fine mineral material, which has a fixed grinding chamber, small grinding medium, with a high speed rotating agitator operation in a mill, stirring mill rely on high intensity mixing effect, effectively promote the grinding medium small rotating at high speed a lot of compression, rotation of the dielectric layer, the dielectric layer can produce a lot of surface pressure and torsion, the crushed material to a suitable size. The test and actual operation of the new type of grinding equipment, the effect is very significant, is a classic of new grinding equipment.
