Coal washing mud water treatment method

The washing process of Shaping Coal Washing Plant includes unclassified raw coal jigging sorting + coarse coal mud interference bed sorting machine sorting + coal mud flotation treatment-concentrated filter tailings and other processes. Therefore, the coal washing plant mainly produces coal mud water through pipeline dripping water, classification, desludging screen water, centrifugal dehydrator centrifugal liquid, final coal desludging screen water, jigging coal mud water desludging screen water and other processes.

If the slime concentration in the slime water is low, the slime recovery equipment and process cannot be used. In order to effectively recover the slime in the slime water, the coal washing plant generally chooses to concentrate the slime. The slime concentration equipment currently used in coal washing plants is usually a natural sedimentation type. Some will add chemical agents to promote slime concentration. The high-concentration slime slurry will be discharged from the bottom of the concentration equipment, and the overflow water containing very little slime will overflow from the top; ④ Whether the washing process is effective depends on the quality of the circulating water. Before the circulating water, it is an important process to clarify the circulating water by reducing the particles and ash in the slime water.

Maintenance and storage method of vibrating screen motor and common troubleshooting

The service life of the vibration motor determines the operating life of the entire screen. Therefore, in the normal production, we must always pay attention to whether the working state of the vibrating screen equipment is normal, whether the vibrating motor is in good working condition, timely check and solve some small abnormalities and faults, and do a good job of cleaning and maintenance, because this can greatly increase the vibration screening. Machine and vibration motor life. dewatering screens supplier Maintenance storage precautions during vibrating screen motor operation The equipment can not be completely dust-free, but also has a harsh environment and dusty conditions. The vibration motor is airless and heat-cooled. It relies on natural cooling, so it must be specially maintained. The following is the maintenance content. 1. It is necessary to pay attention to whether the vibration is abnormal during the use process; 2. Always check if the bolts used in the m...

Fine sand recovery system reduce the sand waste in sand wash

The fine sand recovery system consist of screw sand washing machine , vibrating screen , cyclone. The vibrating Screen was combined with cyclones. Ordinary sand wheel washer or screw sand washing machine can’t process fine sand below 3mm, we researched vibrating screen with cyclone machine. sand recycling system The cyclone is a separation and classification device. When the two-phase mixture to be separated is tangentially introduced into the cyclone from a periphery of the cyclone at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Lzzg's dewatering screen https://www.lzzgmachine.com and sand recovery machine have excellent performance. Compared with Yunnan's local ordinary vibration dewatering screen, the sand washing machine output is twice as high, which greatly improves the production efficiency of the whole line.

300t per hr chalcopyrite washing equipment

Chalcopyrite is a copper-iron sulfide mineral. It often contains trace amounts of gold and silver. Crystals are relatively rare and are tetrahedral-shaped, mostly irregular granular and dense massive aggregates, as well as kidney-shaped and grape-shaped aggregates. Copper yellow, often dark yellow or mottled. The streaks are black with a greenish tint. Chalcopyrite is a relatively common copper mineral, which can be formed in different environments, but it is mainly the product of hydrothermal action and contact metasomatism, and it can often form deposits of a certain scale. The origin is all over the world. In industry, it is the main raw material for copper smelting. In the field of gemology, it is rarely used alone, occasionally as a substitute for pyrite. In addition, it often participates in the composition of some colored stones, inkstones and jade. The high-efficiency spiral chalcopyrite washing machine is mainly used in the washing, grading, impurity removal, and the washing o...
