How to make silica sand washing plant more cost-saving, water treatment technology can be achieved!

silica sand should be recycled and reused after the treatment of water quality. Back-cleaning can make the use of silica sand filter material more fully and not waste. The principle of back-cleaning and utilization of filter material is very simple, which is the friction process.
1. Technical requirements for silica sand water treatment.
  1. The sum of breakage and wear rate of quartz sand filter material should not be greater than 1.5% (percentage by mass, the same below). 
  2. The density of quartz sand filter material should not be less than 2.55g/cm3, except for special requirements for density in use. 
  3. Quartz sand filter material should not contain visible soil, mica and organic impurities, and the water leaching solution of filter material should not contain toxic substances. The content of slime should not be more than 1%, and the content of light substances with density less than 2g/cm3 should not be more than 0.2%. 
  4. The burning reduction of silica sand should not exceed 0.7%. 
  5. The hydrochloric acid solubility of silica sand should not exceed 3.5%.

2. Particle size of quartz sand filter material: 
  1. In quartz sand filter material of various particle size ranges, the particle size smaller than the specified lower limit should not be greater than 3%, and the particle size larger than the specified upper limit should not be greater than 2%. 
  2. The effective particle size of quartz sand filter material is determined by the user.

The backcleaning of silica sand filter is automatic. The backcleaning equipment is equipped in quartz sand filter. This automatic cleaning reduces the production cost to a great extent. It is the most fundamental to make full use of existing resources to achieve no waste.

Real thing!Quality requirements for quartz sand for ultra-white glass

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

Is the flotation processing ineffective? Have you taken these eight factors into consideration?

In the process of flotation by flotation machine , there are many factors affecting the flotation effect, including iradjustable factors and adjustable factors. Non-adjustable factors refer to the nature of ore. Adjustable factors include grinding fineness, pulp concentration, pulp acidity and alkalinity, reagent system (prescription), pulp temperature, water quality, flotation time, etc. Do you know how these factors affect the flotation process? flotation machine 1. Ore properties Ore properties mainly include chemical composition, mineral composition, structure and structure, occurrence state of useful and harmful elements, physical and chemical properties of ore, etc. The fluctuation of raw ore grade will increase the difficulty of controlling flotation process conditions. Among them, the oxidation rate of ore has a great influence on flotation, mainly as follows: A. The oxidation of metal minerals and gangue minerals will change the original mineral and ore structur

Study on high purity sand washing plant

1.Application Status of  high purity silica sand  High  purity silica  sand refers to silica sand with SiO 2 content higher than 99.9%, which is chemically stable and insoluble except HF. Other acids, slightly soluble in KOH solution. It is difficult to purify silica sand because of its various impurities, complex occurrence and different distribution. The earliest raw material for producing high purity silica sand is natural crystal, but with the gradual depletion of natural crystal resources, it has become an inevitable trend to extract high purity silica from ordinary silica sand. High purity silica sand is widely used in high-tech industry. In the semiconductor industry, wafers with excellent thermal properties at high temperatures can be made from molten silica o produce high-tech heat pipes with good thermal stability at high temperatures. In the communications industry, silica glass made from silica sand is the basic material for optical fibers and other photoelectric devic
