Production process of Glass grade silica sand processing line (Take the finished product 20-140 mesh as an example)
Preliminary consideration of the beneficiation process of this beneficiation production line is:
"raw ore - belt conveyor (material conveying) --pre-screen (screening, impurity removal) - —scrubbing machine (mineral surface impurities Removal and scrubbing) - desliming bucket (separation of mud and sand) - hindered settling machine (±20 mesh classification)— -20 mesh sand enters trommel ( Coarse particle safety inspection sieve)—concentrating bucket (adjusting pulp concentration)—hydraulic classifier (±140 mesh classification, 20-120 mesh material enters magnetic separator)—magnetic separator (reducing iron content) --dewatering screen - finished sand pile"
Equipment Introduction
1.pre-screen (screening, impurity removal)
1. vibrating screen: the excitation force can be adjusted at any time, which is convenient for modular design and use
2. The sieving machine structure trend is simplified, and it is reasonable to improve the equipment manufacturing technology level and equipment accuracy.
3. Screening machine has high screening efficiency, large processing capacity and long service life.
4. Pre-selected particles, turf, tree roots and other impurities larger than 4 mesh to improve production efficiency and quality.
2.sand scruber (mineral surface impurities Removal and scrubbing)
1. It is mainly used for the separation of slime and the removal of surface impurities. Pressurized scrubbing will purify the crushing rate, impurities, and non-rounded materials in advance, so as to reduce the crushing rate and purification.
2. Mild scrubbing, unique trough structure and impeller configuration, the scrubbing strength is improved by about 30% compared with the traditional scrubber with the same specifications.
3. Wear-resistant and corrosion-resistant, the tank is lined, and the impeller is made of wear-resistant materials, which has high corrosion resistance and wear resistance.
3.GTN Desliming bucket (separation of mud and sand)
Desilting Machine is a professional equipment for classification, desliming and concentration of quartz sand. Its shape is an upside-down cone. The ore feeding cylinder is set at the center of the liquid surface, and the bottom edge of the cylinder is submerged to a certain depth below the liquid surface. The pulp is fed into the central cylinder along the tangential direction, and flows out from the bottom edge after buffering. The outflowing pulp flows radially to the surrounding overflow weir. During this process, the coarse particles whose settling velocity is greater than the rising velocity of the liquid flow will settle in the tank and be discharged through the bottom grit. The fine particles enter the overflow tank with the surface slurry.
4.GSS hindered settling machine (±20 mesh classification)
Product introduction: The main function is to separate the + 20 mesh sand. The mixture of sand and water is fed from the upper part through a feeding trough, and moves downward in the cylinder under the action of gravity. There is a porous water spray plate at the lower part of the cylinder, and the rising water flow interacts with the falling solid particles to form gradually. In a fluidized bed, the particles of different particle sizes will fall down or move up at the hindered rate of the volume concentration. With the help of the electronic pressure sensor, the pressure of the fluidized bed can be measured and the opening of the discharge valve can be adjusted automatically. degree to ensure accurate grading for the required separation.
5. GSF hydraulic classifier(±140 mesh classification)
1. The material is subjected to the rising water flow in the cylinder, and the particle size is classified according to the specific gravity classification, which has high production efficiency and low energy consumption.
2. Equipped with an automatic control system, the adjustment of the operating parameters is simple, convenient and easy to control
3. The water tank below the cylinder is equipped with special devices. When the water is stopped, the ascending water hole is automatically closed, and the material in the cylinder will not block the water hole and enter the water tank.
5.GTGB high gradient magnetic separator
It uses 4500GS-15000GS permanent magnet magnetic block. The material passes through the belt and the magnetic material is adsorbed. Then the belt rotates to separate the raw material from the magnetic material. It mainly reduces the crushing rate and acid solubility.
6. GTLH high grandient vertical ring magnetic separator
1.4T magnetic field strength, to further removes iron oxide
7. GTTS dewatering screen
It is used to wash and dehydrate the ore. Because the water content after the finished product is too high, it needs to be dewatered through a dewatering screen to reduce the water to a controllable range. The reduction of the water content can improve the efficiency of the dryer.
8. Environmental protection circulating water treatment
Flocculation sedimentation method in physical and chemical method: After the primary sedimentation of the washing wastewater, the large particulate matter in the wastewater is removed, and the effluent enters the coagulation reaction tank. The pollutants dissolved in the water body polymerize to form larger aggregate flocs (commonly known as "alum flowers"). Because the proportion of the "alum flowers" is greater than 1, it precipitates at the bottom of the water body under its own gravity, so Separation of pollutants from water bodies
