2、 Performance of quartz sand dryer

The new energy-saving quartz sand dryer independently developed is designed using modern methods, and the equipment is in a natural balance state during operation, with the main unit working quite smoothly It is a green and environmentally friendly drying equipment. Not only does it provide customers with a wide selection, reasonable matching, reliable quality, and high cost-effectiveness of drying equipment, but it also helps them design processes and is responsible for later installation, commissioning, and maintenance services.

3、 Application of quartz sand dryer

Widely used in metallurgy, mining, building materials, coal, refractory materials, ceramics and other industries, it is suitable for drying materials with different hardness and high humidity, such as quartz sand, shale, quartz sand, construction waste, etc. in various regions

Obviously, it has a very prominent effect on the drying requirements of internal combustion and other industry materials, especially for brick factories.

4、 Characteristics of quartz sand dryer

1. The quartz sand dryer requires the moisture content of the material, and it should not be blocked during the production process, with high fineness.

2. The noise generated during quartz sand is greatly reduced, and the equipment operates smoothly without the need for foundation installation.

3. This device incorporates bidirectional gap adjustment technology, which allows for free control of the particle size of the equipment's discharge, making production more user-friendly. The design of the quartz sand dryer is very unique and easy to maintain, requiring only one person to complete

5、 Working principle of quartz sand dryer

Dry and wet materials are transported to the hopper by a belt conveyor or bucket elevator, and then enter the feeding end through the feeding pipeline through the feeding machine of the hopper. The slope of the feeding pipeline should be greater than the natural inclination angle of the material, so that the material can flow smoothly into the dryer. The dryer cylinder is a rotating cylinder slightly inclined from the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, coming into counter current contact with the material. There are also cases where the heat carrier and the material flow together into the cylinder. As the cylinder rotates, the material moves to the lower end under the action of gravity. During the forward movement of the wet material inside the cylinder, it is directly or indirectly heated by the heat carrier, allowing the wet material to dry, and then sent out through a belt conveyor or screw conveyor at the discharge end. There is a copying plate installed on the inner wall of the cylinder, which is used to pick up and sprinkle the material, increase the contact surface between the material and the airflow, improve the drying rate, and promote the advancement of the material. Thermal carriers are generally divided into hot air, flue gas, etc. After passing through the dryer, the heat carrier generally needs a cyclone dust collector to capture the materials carried in the gas. If further reduction of exhaust dust content is required, it should be discharged after passing through a bag filter or wet dust collector.

quartz sand

Quartz sand is a non-metallic mineral that is hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white or colorless semi transparent, with a hardness of 7. Quartz sand is an important industrial mineral raw material and is not a hazardous chemical. It is widely used in industries such as glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical fluxes, metallurgy, construction, chemical industry, plastics, rubber, abrasives, etc.
Purification method of industrial quartz sand:

1. Scrubbing and desliming refers to the use of mechanical force and the grinding force between sand particles to remove thin films of iron, bonding and muddy impurities minerals on the surface of quartz sand, as well as further pulverize mineral aggregates that have not yet formed monomers, and then achieve further purification of quartz sand through grading operations.

2. Magnetic separation is mainly used to remove magnetic minerals from quartz sand. For example, weak magnetic minerals such as hematite, limonite, and biotite can be removed by a strong magnetic machine, while strong magnetic minerals such as magnetite can be removed by a weak magnetic separator. (Related reference magnetic separator)

3. Flotation is used to remove impurities such as feldspar and mica from quartz sand that cannot be removed by magnetic separation, further improving its purity. (Related reference flotation machine)

4. Acid leaching, which utilizes the characteristic that quartz is insoluble in acid (except HF acid), while other impurity minerals can be dissolved by acid solution, can achieve further purification of quartz.

5. Microbial leaching. It refers to the use of microorganisms to leach thin film iron or impregnated iron from the surface of quartz sand particles, which is a recent development
