  Flotation machine also named as flotation cell is one of the necessary equipment for nonferrous, ferrous and other metal separation in concentrator. It also has good flotation effect for fluorite, talc and other stone materials, and is widely used in mineral processing, metallurgy, chemical industry and other fields. So what are the commonly used flotation machine models? How to choose the model?   BF flotation machine/flotation cell 1. What are the models of flotation machine? Up to now, the development of flotation machine has a history of several decades, and various technologies and processes tend to be mature. On the one hand, the quality and performance of the equipment have reached the international level, with the characteristics of high efficiency, energy saving and environmental protection; on the other hand, the model is also very perfect, resulting in a series of BF, SF, XCF and KYK flotation machines. 1 》 BF series flotation machines BF series flotat...

quartz sand powder for coating and painting High purity quartz sand powder has special optical properties that conventional SiO2 does not have. It has strong ultraviolet absorption and infrared reflection characteristics. The addition of silica powder to the coating can form a shielding effect on the coating, achieve the purpose of anti ultraviolet aging and thermal aging, and increase the thermal insulation of the coating. The hardness and adhesion of the UV curable coating are improved and the absorption of UV radiation is weakened by doping high-purity silicon powder into the UV curable coating. Thus, the curing speed of UV curable coating is reduced. High purity silica powder has a large specific surface area, shows great activity, and can form a network structure when the coating is dry. At the same time, the strength and finish of the coating are increased, the suspension of the pigment is improved, and the color of the coating can be kept unchanged for a long time. The amo...

Ultra-clear glass can achieve a transmittance of more than 91.5%, and its optical properties are widely used in solar power generation, solar thermal power generation, information display, architectural decoration, and smart agriculture. The iron content in the ultra-clear glass is 0.015% or less, and the high-quality ultra-clear glass for the photothermal glass for clean energy, the electronic glass for information display, and the like requires higher transmittance, and therefore requires silica sand has a lower iron content, which puts higher demands on the raw materials of glass. Among the ultra-white glass batch materials, quartz sand generally accounts for more than 60% of the weight ratio, which is the main factor affecting the iron content in the glass, and the melting temperature of the quartz sand is high, which determines the melting speed of the glass, so quartz sand in glass batch materials is the main research object. What are the requirements for the chemical co...

Quartz sand is mainly composed of silica, which is an important raw material for nearly 100 kinds of industrial products, such as glass, electronics and electrical appliances, optical fiber semiconductor, water treatment, mechanical casting, artificial quartz stone, daily ceramics, metallurgy, superhard materials, chemical industry, cement, functional filler, petroleum drilling, etc. Distribution of quartz resources China's quartzite deposits are mainly distributed in Qinghai, Liaoning, Shanxi and other places: quartz sandstone deposits are mainly distributed in Sichuan, Hunan, Jiangsu, Zhejiang, Shandong and other places; quartz sands are mainly distributed in Fujian, Guangdong, the south of Guangxi, the northwest of Hainan and the north of Shandong, and there are also the eastern part of the West Liaohe River, the middle reaches of the Yellow River and the banks of Panyang lake and Luoma Lake. Quartz sand production In terms of quartz production, China's qua...

Let's get to know silica sand today. With the rapid development of traditional glass industry, quartz sand is generally used to make flat glass, float glass, glass products (glass can, glass bottle, glass tube, etc.), optical glass, glass fiber, glass instrument, conductive glass, glass cloth and special anti ray glass. Especially with the development of global economy, the standard of building standardized management and the improvement of technology level of glass industry, all kinds of glass will be brilliant in the future construction. Quartz glass has low coefficient of thermal expansion, high temperature resistance, good chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, the best UV spectrum performance, visible and near-infrared spectrum performance, and has higher mechanical properties than ordinary glass. Quartz sand is an important raw material of quartz glass. With the increasing demand of glass industry, quartz sand ...

Quartz sand is an important industrial mineral raw material, non chemical dangerous goods, widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries.     In the market, silica sand is the most basic quartz mineral product, which can be divided into quartz sand, quartz powder, ultra-fine silica powder, cristobalite, high-purity quartz, etc. according to the different grade and processing degree of the ore body itself. Quartz sand mainly refers to river sand, sea sand and weathered sand with more silicon dioxide. In addition to the main component silicon dioxide, it also contains iron oxide, clay, mica and organic impurities. It is mainly used as raw material of glass industry and ceramic industry, and flux of metallurgical industry. Fine quartz sand can be used as abrasive for grinding glass, etc.     The main products of quartz sand...
