With the extensive use of quartz resources, high-quality crystal and vein quartz are decreasing day by day, and low-grade quartz resources are receiving more and more attention. LZZG has developed natural quartz sand and quartz sand purification processes for customers. High-purity quartz sand refers to quartz sand with a silica content higher than 99.9% (3N). Low-end, mid-range and high-end products are distinguished by silica content of 99.9%, 99.99% and 99.998%.

Indonesian kaolin has a long way to go from its origin to being usable in various industrial processes. Below we will see how it was created and where it comes from. Kaolin gravity separation equipment First, kaolin must be mined using water jets. The kaolinite is then centrifuged with a kaolin slurry, thereby removing the sand, and the kaolinite is ready for triple filtration, using 100 to 325 mesh screens. The kaolinite is purified and solidified after being filtered by a high-pressure pump and a filter press. In this step, a kaolin block with a moisture content of 33% to 35% is produced. If you want kaolin with a lower moisture content, it must be naturally dried until the moisture content is between 12% and 14%. This kaolin clay has a moderate moisture content compared to dry kaolin clay, which contains only 1-4% moisture.

The basis for selecting a hydrocyclone is: ① The volume of slurry required to be processed Q (m3/h); ② The classification particle size (or the maximum overflow particle size) d (mm). First, determine the diameter D of the cyclone based on Q and d. Generally, when the overflow is thicker and the production capacity is large, a large-sized cyclone is used, otherwise a small-sized cyclone is used. When the required production capacity is large and the overflow is very thin, small-sized cyclones can be connected in parallel to form a cyclone group.
