As we all know to live in this world we have to perform some activity by which we can earn money. There are many activities by which we can earn money and meet the standards to live in this society. And from one of them is franchise. Franc Small offices have unique needs, and thatincludes document shredding. Designed with the smaller business inmind, the Dahle 20314 is a cross-cut shredder that offers Level 3security and brings you into compliance with federal regulations. The
Equipment of grinding silica fume has extrusion mill, disc mill, raymond mill,jaw crusher, etc. These devices not only to high energy consumption and lowefficiency. Makes the production of silica fume stagnant. But the column millis a new type of vertical mill. Use medium speed pulsating, continuous repeatedlow-pressure roll grinding principle and scientific structure design, so it hasboth high pressure roller press roller mill performance, and with no defects.Reduction gear device so that the spindle is rotated when the motor driven,mounted on the spindle bearing and of several rollers mounted on the carriageto rotate in the ring tapered liner adjustable gap between the rollers and theinner liner, when the material from the inlet into the mill, due to the forceof gravity and upper pusher role, the material uniformly from top to bottom bylining four weeks, and roller repeated rolling into powder, the last from the milllower part of the automatic nesting. As the roller wheel relative to therevolution and rotation of the liner for the rule, and can vary with the sizeof the material layer thickness and the material particles flexiblefluctuations, and the rollers and the liner no contact, thus avoiding bothbetween subject to reasonable impact on energy consumption and wear, thematerials repeatedly rolling and grinding here, plus grinding roller and theliner material is selected to wear better wear-resistant alloy multi-elementsteel, to minimize the extent of the contamination of material processingmachinery iron powder processing.Silicon metal powder, also known asindustrial silicon powder, is silvergray or dark gray powder, with metal luster. Its high melting point, good heatresistance, high resistivity, is highly resistant to oxidation, known as the"Industrial MSG" indispensable basic raw material for many high-techindustries. Silicon large for smelting ferrosilicon alloy as a reducing agentfor the iron and steel industry as an alloying element in a variety of metalsmelting. Good silicon or aluminum alloy, the vast majority of cast aluminumalloy containing silicon. Silicon is the raw material of ultra-pure siliconelectronics industry, ultrapure semiconductor silicon electronic devices dohave advantages of small size, light weight, good reliability and long life.Silicon single crystal doped with specific trace impurities made of high-power transistors, rectifiers and solar cells is better thangermanium crystal .The main uses of silicon metal powder:silicon metal powder is widely used in refractories, powder metallurgyindustry, in order to improve the high temperature, abrasion and oxidationresistance. Its products are widely used in steel-making furnaces, kilns, kilnfurniture. In organic silicon chemical industry, metal powder is the basic rawmaterial of the silicone polymer synthesis, such as for the production ofsilicon monomers, silicone oil, silicone rubber, preservatives, so as toimprove the heat resistance, electrical insulation properties, corrosionresistance, waterproofing other characteristics.Industrial silicon powder made by pulling monocrystalline silicon processed is widely used inhigh-tech fields, integrated circuits, electronic components essential rawmaterials. The metallurgical foundry industry, silicon metal powder as anon-iron-based alloy additives, silicon steel alloy agent, and thus to improvethe steel hardenability. Industrial silicon powder can also be applied to somemetal reducing agent for the new ceramic alloy. Silicon metal powder is mainlyused for the basic raw material of silicone polymer materials (such as silicon,trichlorosilane, silicon, etc.).Source:http://www.mhcmp.com Article Tags: Silicon Metal Powder, Silicon Metal, Metal Powder, Silicon Powder, Widely Used
