The hydraulic classification is a mixture of mineral particles in water according to the sedimentation speed difference, and the mixed particle group with a wide particle size range is divided into a plurality of particle groups having a narrow particle size range. The classification process is based on their different speeds of movement in the water, where large, light and small and heavy ore particles have the same settling velocity and thus form a level of granularity. Therefore, the hydraulic classification is performed not only by the particle size but also by the specific gravity. The equipment used for grading is called a classifier, and the commonly used hydraulic classifier is a box type hydraulic multi-chamber classifier, which is also called a mechanical concentrating groove classifier. This classifier used in tungsten ore beneficiation plant, as the shaking of sorting before material classification. Suitable fractional particle sizes range from 2 to 3 mm, but are less effective for fractionation of less than 0.074 mm. 2 , the role and application of washing? What is the common washing equipment? Washing is used to treat ore and useful minerals that are bonded to the clay . The ore washing process includes two stages of dispersing the clay and separating the separated clay material from the particulate material. Usually washing process for iron ore clay, manganese ore containing gold, tin, tungsten, platinum, and other useful placer. It is also used to process sand and clay materials for construction. In metal concentrators, washing is generally done as preparatory work, such as jigging, hand picking or washing before crushing. Commonly used washing equipments include chutes, flat washing screens, cylindrical washing machines and trough washing machines. The CXK-160×763 tank type washing machine produced in China has a body size of 7630×1600 mm (inside length × inner width). The effect is better. When the ore particle size is less than 75 mm, the easy-washing ore production capacity can reach 70 tons/hour.

The company's standard cooling tower according to the international design conditions design, can also provide customers with non-standard operating conditions or specific sizes under the special, special design.
The circulating water pump suction port shall be located below the water level of the cooling tower catchment basin, and the cooling tower outlet pipe shall not be allowed to be higher than the maximum water level of the catchment basin.
Pipe mounts should be pipe racks and cooling towers should not be allowed to directly bear the weight of the pipes.
The rehydration pipe of the cooling tower should be provided with a support stand to avoid vibration of the pipe when the float valve is rehydrated.
Rehydration pressure should be below 5m water pressure, national standard
The flannage pressure is 1.0Mpa.
When two or more units are assembled, our company will provide a connecting balance tube to balance the chassis water level. The tower top inlet should be set with a conditioning valve in order to enter each
.The water level of the tower is uniform.
The noise is measured at dm1.13VL-W at the equivalent diameter of the cooling tower (Dm1.13VL*W), 1.5 meters above the ground height, wherein L and W are the shape rulers of the tower
inch long and wide).
The use of cellular continuous blister series of diversion,heat dissipation, water collection three-in-one native filler, the whole suspension, gravity cloth water, low drop of water, with cold effect
High, low energy consumption, less drift water, less noise and so on, floating water rate is less than 0.001%.
When connecting different types of towers, the bottom basin water level height of different types of towers must be taken into account, and the base height must be adjusted to maintain the water level balance of the towers.
