Quartz sand is a quartz particle made by crushing quartz stone. Quartz is a non-metallic mineral that is a hard, wear-resistant, chemically stable silicate mineral. The color of quartz sand is milky white, or colorless translucent, with a hardness of 7 on the Mohs scale. Quartz sand is an important industrial mineral raw material, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries.
Quartz sand is a hard, wear-resistant, chemically stable silicate mineral, according to its use, the common specifications are: 05-1mm, 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80 mesh, 100-120 mesh, 1000 mesh, 1200 mesh...
The fluidized bed ultrafine pulverizer uses a plurality of oppositely arranged nozzles to form a high-speed air flow, and then uses the high-speed air flow to accelerate the material to supersonic speed so that it collides with each other at the intersection of the nozzles to achieve the purpose of ultrafine grinding. The crushed material enters the classifier classification chamber with the updraft, and due to the high-speed rotation of the classifying rotor, the particles are not only subjected to the centrifugal force generated by the classifying rotor, but also by the centripetal force generated by the air flow. When the centrifugal force of the particles is greater than the centripetal force, that is, the coarse particles above the graded particle size return to the crushing chamber to continue to impact and crush, and the fine particles enter the cyclone separator and collector with the air flow to collect, and the gas is discharged by the induced draft fan.
Equipment features:
Green and environmental protection: low temperature without medium crushing, to ensure the high purity and physical properties of the product. The equipment operates under negative pressure and has no dust pollution.
High efficiency: The full use of jet energy can improve the crushing efficiency by 30% compared with the traditional jet mill pulverizer, and the grading accuracy is higher.
Low wear and tear of the equipment: the structure of "fluidized bed + vertical classifier" can process ultrafine powder with high purity and ultra-narrowness, avoiding the wear and tear of the grading part of "fluidized bed + horizontal classifier", especially suitable for ultrafine grinding of high-purity and high-hardness materials.
High output: When producing products with narrow particle size distribution, the yield is more than 1 times higher than that of traditional pulverizers.
Multi-purpose: one machine is multi-purpose, can be used as a pulverizer or as a classifier. The crushing particle size range is wide, and the particle size of the product can be 0Arbitrary adjustment in the range of 2-200 m.
Intelligent: The equipment can realize all automatic control, simple operation, stable operation, and excellent production environment.
Reasonable design: the structure of the equipment is compact, there is no storage and no dead angle in the crushing host, it is easy to disassemble, wash and disinfect, and it is convenient to replace the variety of crushed materials.
The whole system adopts automatic control, which can realize one-button start and stop, simple and convenient operation, and can be connected with the central control to achieve remote control.
