The value of recycling pond water has been recognized in previous patents. U.S. Pat. No. 4,044,107 Houghtaling mentions the possibility of using gypsum pond water in the phosphate rock grinding operation. However, it recommended taking precautions against corrosion, for example, by using a rubber-lined mill and non-corrodible balls. These precautions add to the initial expense of the grinding mill installation and make its periodic maintainance after continued operation more expensive.
Paper-making: used as the filler of paper and paperboard. The paper product can be smoother and finer. It can also save up raw material.
By rotating disc motor reducer drive, the material falls from the spout central disc, and by rolling the roller moves to the edge of the disc under the action of centrifugal force, the material crushed overflow from the edge of the disc, and was from the nozzle ring (the wind ring) speed up the hot air to the vertical mill with one of the efficient separator, coarse separation after sorting returned to the disc, re-grinding; powder with the air out of the mill, in closed systems dust collection device down, that is the product. Not hot air from the coarse particles with unexpected materials and metal parts from the wind into the ring at the sink, the scraper scraped from the plate, the outer loop of the bucket lift machine feed mill for regrinding.
Grinding of raw materials requires considerable energy. In the tube mills that were used for grinding, energy efficiency levels were low. Therefore, the vertical roller mill has been introduced in the market. The vertical roller mill has the installation space is smaller compared with tube mills and it has high energy efficiency. The vertical roller mill is a kind of crushing equipment which saves energy and is highly efficient. Vertical roller mills have integrated the crushing and grading into a single whole, satisfying the requirements of the consumers. The key purpose of a vertical rolling machine is to perform the powder crushing manufacturing of materials such as kaolin, calcite, wollastonite, feldspar, limestone, glaze, fluorite, light dry stone coal, potassium salt slag, vermiculite, barite, slag, mica, brucite, spores, garnet, quartz, etc. Vertical roller mills can also be used in non-metal mining areas with Mohs hardness of less than seven degree, such as in mining metallurgy, electronics, chemical industry, food, medicine, agriculture, daily chemicals, buildings, and so on.

The grinding barrel and shaft adopts forced water circulation and the mechanical seal adopts oil cooling system,which ensure the best cooling effect.
Amy Halloran likes flour. Her book, "The New Bread Basket," is about the farmers, millers, bakers, and brewers who are reviving regional grain production.
In short, with portable saw mills, you have the option to do your woodworking and manage the mill in an easy manner. It will allow you to increase your productivity as a diy user.
Smarter process control ensures consistent grinding to the correct size whilst the mill is in operation. All this is done in a dry process, reducing the oxidation of the float product.
solve the major problem which current domestic crushing industry can not solve. Fineness can reach at 5 to 10 microns.
