SCM ultrafine mill is a fine and ultra-fine powder processing equipment, which is mainly suitable for medium and low hardness, Mohs hardness < level 6 of non-explosive brittle material, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectories, diatomite, barite, gypsum, alum stone, graphite, fluorite, phosphate rock, potassium ore pumice, etc.

SCM ultrafine mill is widely used in the metallurgy, building materials, chemicals, mining minerals in areas such materials.

SCM ultrafine mill absorbed domestic and foreign manufacturers of merit, after full investigation, research, testing 12 kinds of mills and horizontal hammer mill, through several studies and experiments and the development of high efficiency and low cost of ultrafine mill.

Points of SCM ultrafine mill accessories selected:

SCM ultrafine mill accessory structure and parameters of the standard and ordinary mill is a difference, if the need for replacement of wearing parts, and these parts choices need to follow certain rules. The first point is the first model, the same mill as a result of different technical parameters, the diameter and the size and the design of the structure of its parts are different, buy micro-grinding of original parts need to consult the manufacturer. The second point is the quality, sebang SCM micro-grinding mill roller and grinding ring forging high manganese steel materials, in the same material standard, its longer service life of wearing parts five times, while a good product size distribution also make a one-time product fineness up D97≤5μm. The third point is the price, purchase accessories to fully consider the cost of investment, shop around and choose the most economical and reliable partner.

Working Principle:

SCM Ultrafine Mill, Grinding Mill

After crushing milled multilayer, the materials with the wind flowing enter the separator machine powder machine grading, the role of classifier wheel, does not meet the requirements of the fineness of the material falling back again milling grinding chamber, in line with the fine material degree requirements are separated into the air to collect partial powder inside the cyclone powder collector, discharged by the discharging device is finished at the bottom of the powder. Powder from the whirlwind of powder into the rest of the upper pulse dust collector, and adhere to the surface of the bag, pulse valve control pressure air blowing into the bag inside it instantly cause severe swelling bag fluctuations, through the bag the sudden drop bombs shake powder adhesion, falling in the lower dust powder, the screw conveyor will bring together two powders were collected discharge is finished. The filtered air flow through the wind machine muffler emitted into the air.

Equipment for the traditional ultra-fine grinding equipment in the production process is easy to damage the characteristics of the redesign of the equipment in the interior of the grinding cavity is not the use of rolling bearings and screws, such a design can effectively reduce the production process of equipment easily damaged problems, to ensure the stability of equipment operation, in addition, equipment specifically for environmental issues made some improvements, the equipment in the design of the use of pulse dust remover and muffler, can effectively reduce dust pollution and noise pollution, is an environmentally friendly equipment.

How to solve the environmental problems of ultrafine mill

For ultrafine mill production line of environmental issues, mainly dust and noise, these two aspects of the environment will be polluted, and the health of the staff has adverse effects, so need to be resolved in a timely manner, the following to introduce the solution of these two problems.

For the dust problem, in the production of ultrafine mill, there is more or less the problem of dust, feeding mouth, discharging mouth and fan seals, because of fine particle size, very easy to fly out of the sealed place, this situation is the solution is to use the negative pressure system, the use of good sealing equipment and fine grading equipment, when necessary in the crushing workshop installation of dust removal system to ensure clean production workshop, especially the ultrafine mill in the pigment, dye, fiber powder and toxic powder production process, It is particularly important to ensure the safety of staff

For the noise problem, in the material for grinding, the machine in the production line, generally produces some noise, but generally speaking noise in a reasonable range, if beyond this range, it is necessary to use the silencer equipment to carry out the sound operation, which is to ensure the ultrafine mill environmental protection of another important aspect of production
