What is silicon powder? Quartz powder (quartz sand) is also called silica micro powder. Its English name is quartz sand powder, silica flow, ground quartz. Silica micropowder is a kind of hard, wear-resistant and chemical stable silicate mineral. Its main mineral composition is SiO2. The color of quartz sand is milky white or colorless and translucent, hardness is 7, brittle and non cleavage, shell fracture, oil luster, density is 2.65, bulk density (20-200 mesh is 1.5). Its chemical, thermal and mechanical properties are obviously anisotropic and insoluble in acid. Slightly soluble in KOH solution, melting point 1650 ℃ . Quartz sand is a kind of product whose fineness is below 120 mesh (less than 120 mesh) after being processed. More than 120 products are called quartz powder. Production process of silica powder Quartz powder can be produced in two ways: quartz sand powder making plant ( dry method) and quartz sand powder making plant (wet method). Various conventional specif

Silica slab has the characteristics of pollution-free, wear-resistant, scratch-resistant, corrosion-resistant, durable, and rich in color. In the world, silica slab has become an emerging green tabletop material, which is widely used in public buildings and home building materials. The industrial chain process for silica slab is: The raw materials for silica slab are quartz stone, pulverized stone, quartz sandstone, feldspar quartz ore, argillaceous quartz sand ore. The quartz sand raw material is passed through the silica sand processing&sand washing plant to make silica sand, and then silica sand and resin are mixed and made into silica slab, which can be used for making countertops, sinks, floors, walls, furniture and commercial decoration. Silica sand processing & sand washing plant Upstream - silica sand processing plant I. What are the raw materials for silica slab? In theory, all quartz mines can be made into silica slab. However, at prese

The function of silica sand ball mill in beneficiation is to dissociate the useful mineral components after crushing to the state of monomer dissociation, so as to provide suitable pulp with suitable size and concentration for beneficiation operation. The final beneficiation index depends mainly on the quality of grinding products. Therefore, the grinding quality of the silica sand ball mill is particularly important. It must meet the concentration required by the separation operation. In order to meet the requirements, the operators of the ball mill not only need to know the routine operation and maintenance process of the ball mill, but also need to master the following knowledge. Silica sand ball mill Controlling feed size of silica sand ball mill The size of grinding particle of silica sand ball mill has a great influence on the productivity and energy consumption of ball mill. Generally, under the specified grinding fineness, the finer the feed particle size, the highe

At present, the crushing of ore mainly relies on the mechanical force. The most common ones are as follows: 1. Crushing method: When two crushing working faces are used to press the material, the material is crushed. The characteristic of this method is that the force is gradually increasing and the scope of the force is large. 2. Splitting method: The material is broken by wedging the sharp teeth into the splitting force of the material. Its characteristic is that the action range of the force is concentrated and local rupture occurs. 3. Breaking method: When material is broken, it is broken by bending force concentrated in relative direction. This method is characterized by not only the splitting force at the point of external force, but also the bending force, so it is easy to break the ore. 4. Grinding method: The crushing working face moves relatively on the material, resulting in the shear force on the material. This force acts on the surface of the ore and is su
