Description

Pre-crushing device for high-purity quartz sand

Technical Field

The utility model relates to a quartz sand processing equipment technical field specifically is a high-purity quartz sand's reducing mechanism in advance.

Background

The quartz sand is quartz particles formed by crushing and processing quartz stones. Quartz is a non-metallic mineral, a silicate mineral that is hard, wear resistant, and chemically stable. The color of the quartz sand is milky white or colorless and semitransparent, and the Mohs hardness is 7.

Quartz sand is a variety of colorless, transparent quartz, known by the Greek as "Krystallos" and means "white ice" which they believe is durable and strong ice. Ancient Chinese believes that the crystal contained cold in the mouth can quench thirst. The quartz sandstone is consolidated clastic rock, the content of the quartz clastic rock is more than 95 percent, the quartz clastic rock is from various magma rocks, sedimentary rocks and metamorphic rocks, the heavy minerals are less, and the associated minerals are feldspar, mica and clay minerals. The quartzite is divided into two causes of sedimentation and deterioration, wherein the former causes are not obvious in boundary of detritus particles and cement, and the latter causes are quartzite ores with deep deterioration degree and pure quality. Vein quartz is formed by hydrothermal action, and is almost entirely composed of quartz, with a dense block structure. The mineral content in the quartz sand is greatly changed, quartz is taken as the main material, and feldspar, mica, rock debris, heavy minerals, clay minerals and the like are taken as the secondary materials.

The traditional double-roller crushing method is characterized in that materials are directly fed in from the upper parts of two rollers, the acting force of the rollers is gradually increased from the time of being bitten by the roller surfaces, after the materials are subjected to the high pressure of about 50-200MPa, the materials are discharged from the lower part of a machine in an ideal granularity, a large number of cracks are generated inside the discharged materials except for powdery materials with a certain proportion, the grinding energy consumption can be greatly reduced in the further crushing process, for the industry of high-purity quartz sand, the traditional crushing method has obvious defects, the high-purity quartz sand product does not need to be further refined and crushed or ground due to the fact that the high-purity quartz sand product needs to have a certain granularity or mesh number (40-180 meshes), the large particles are enabled to be subjected to larger overall force when the large particles enter the rollers, and small particles inside are also subjected to high pressure, so that micro cracks are generated on the sand product to a large degree, the roller pair has overlarge particles and larger abrasion on the roller surface, which can also cause the granularity of the quartz sand product to be too fine, the quartz sand particles with certain granularity after being crushed by the roller pair are not suitable to have crack structures inside or on the surface, otherwise, other elements or impurities are easily adsorbed inside the cracks and are not easily removed in the later acid treatment or water washing process, thereby greatly influencing the purity of the high-purity quartz sand product. Therefore, the invention improves the technical scheme and provides a pre-crushing device for high-purity quartz sand.
