Quartz stone, generally speaking, quartz stone is a new type of stone synthesized by more than 90% quartz crystal plus resin and other trace elements. It is a large-size plate that is pressed by a special machine under certain physical and chemical conditions. Its main material is quartz.
Quartz is a mineral that easily becomes liquid when heated or pressurized. It is also a very common rock-forming mineral, found in all three types of rock. Because it crystallizes at the latest in igneous rocks, it usually lacks a complete crystal plane and is mostly filled in the middle of other crystallization minerals. The composition of quartz is the simplest silica, glass luster, no cleavage surface, but with a shell-like fracture. Microcrystalline quartz is called chalcedony, agate or jasper. Pure quartz is colorless, but presents different colors due to impurities that often contain transition elements. Quartz is very stable and does not easily weather or change into other minerals. According to the degree of SiO2 crystallinity, it can be divided into crystalline quartz crystal, polycrystalline quartzite jade. Gloss: Glass luster. Color: no, white, with a touch of gray, yellow to orange, purple, deep purple, pink, gray brown, brown, black. Streak: white. Specific gravity: 2.65 ~ 2.66. Category: Metamorphic rock, which is metamorphosed by sandstone.

Quartz Processing Plant

Quartz stone powder is generally divided into coarse powder processing (0-3mm), fine powder processing (20 mesh -400 mesh), ultrafine powder processing (400 mesh - 1250 mesh) and micro powder processing (1250 mesh - 3250 mesh) Types of.
The first stage: broken
The ore quartz stone enters the first-stage crusher through the silo for coarse crushing, and the coarsely crushed material passes through the belt conveyor to enter a special number control sand machine, and the quartz stone is finely crushed to 40-80 mesh to occupy more than 60% fineness. Save ball mill wear and increase production.
Second stage: screening
The finely divided materials are sieved into a linear sieve, and the desired 6-10 mesh, 10-20 mesh, 20-40 mesh, 40-80 mesh finished products are sieved and sold as quartz sand, and the remaining materials are fed into the mill through a conveyor. Head warehouse.
The third stage: milling and powder selection
The material entering the grinding head bin is ground into a special ceramic ball mill through the feeder, and the ground material is transported into the conveyor to the high-efficiency classifier for classifying the quartz stone ultrafine powder 140 mesh, 325 mesh, 600 mesh, 1000 mesh. 1,1600 mesh. (The inlet and outlet of the ceramic ball mill are made of stainless steel, the inner lining is made of high-aluminum ceramics, and the grinding body is made of high-aluminum ceramics. The powder selection machine is made of stainless steel to ensure that the materials in the production do not contain iron and ensure the whiteness of the quartz powder.)
The fourth stage: dust removal and finished products
The mill is equipped with a pulse bag filter to collect the fine dust into the dust collector to meet the environmental protection requirements in the production. The finished powder is transported to the finished silo through the conveyor, and the non-standard material is returned to the mill through the conveyor. Continue grinding to form a loop that increases efficiency.
