Guilin Hongcheng Research and development and production of Raymond mill , can grind more than 100 kinds of ore, many overseas countries have engineering cases

Guilin Hongcheng Ramon mill  manufacturers learned that activated carbon is a kind of special microcrystal structure, huge specific surface area, developed fine pores, strong adsorption capacity of carbon. As a good decolorization and adsorbent, it has been widely used in medicine, sugar, food, chemical industry, national defense, agriculture, mineral processing and people's clothing, food, shelter and transportation, in recent years. With the development of national economy, activated carbon has become one of the important chemical products to control environmental pollution, water quality treatment, gas purification and improve the quality of human life. In order to improve labor productivity and improve product output, users put forward requirements to improve the filtration speed of activated carbon. One way is to improve the particle size index of the product, which needs to be achieved through the activated carbon Raymond mill. Today I will introduce the role of activated carbon Raymond mill to improving the filtration speed of activated carbon.

Activated carbon particle size index and the relationship between filtration speed: everybody knows, the greater the solid particle size, the accumulation gap relatively larger, liquid through ability is relatively enhanced, but activated carbon as an adsorption decolorization agent, under the condition of the same crystal structure, the greater the particle size, the specific surface area is relatively reduced, decolorization adsorption force is weakened, so, there is a way to keep the original product size, namely does not change the activated carbon adsorption and decolorization force, through other means to improve the filtration speed of the product? Through the production practice research, the answer is yes. The speed of liquid passing through the filter layer is not only the particle size, but also the shape.

The influence of different types of activated carbon pulverizing equipment on the filtration speed of activated carbon: the previous activated carbon after the activation process, mainly through the ball mill (porcelain ball as the medium) to achieve, generally grinding into 200 pieces of 90% of the powder carbon. We will this carbon through the low power display lens observation, found that its grain is mainly round and ovate, a few are flat strip multilateral cube shape, its filtration speed is generally 18~ 19 seconds, during which its filling density is generally 0.405 g/cm3, a large distance from the user's filtration speed is <8 seconds. Through the experiment increased the particle size to 200 mesh 60% when the filter rate can be increased to 10-11 seconds, but decolorization, adsorption force by n.5~1 (0.15% armor force) to about 8.5ml, obviously due to particle size, activated carbon ratio surface area, causing decolorization force drop, if keep decolorization force unchanged, the processing cost to increase 1000 yuan per ton, the user cannot accept, is also not a way of economic.250 mesh activated carbon laser mill downstream customers through investigation and research, selected 250 mesh activated carbon Raymond mill for pulverizing operation, processed powder carbon in the condition of the same, filtration speed between 7.5~8 seconds, than universal grinder and ball mill 2.5~3 seconds, grams fill density further drop to 0.362g / c fully meet the user requirements, improve the competitiveness of activated carbon products.

Activated carbon Raymond mill to improve the effect of activated carbon filtration speed: activated carbon Raymond mill processing activated carbon powder mainly needle, and the proportion of round oval very few, this is due to the particle characteristics further change, making the filling density drop further, carbon layer channel equivalent diameter, void increase, further improve the filtration speed. From Raymond machine working principle can also know, the machine crushing material mainly rolling, less of carbon particles wear, so that the particles mostly keep separation, and ball mill and universal crushing machinery for carbon particles more or less angular wear, to increase the filling density, reduce the ability of liquid through.
