A Detailed Explanation of theMain Application Areas and Specific Scenarios of Slurry Pumps
As the core equipment for transporting solid-liquid mixtures, slurry pumps have a wide range of applications, mainly concentrated in industrial sectors that require the treatment of high concentration, highly abrasive, or highly corrosive slurries.

The following is a detailed explanation of the main application areas and specific scenarios of slurry pumps:

Ⅰ、 Mining industry (the most important and demanding application field)

Mining is the most widely used and harsh operating field for slurry pumps, which almost runs through the entire beneficiation process.

Specific scenario:
1. Ore mining (pit drainage and transportation): Used in open-pit or underground mines to extract accumulated water from pits containing sediment and gravel particles.
2. Grinding circuit: The crushed ore is mixed with water and transported to a ball mill or semi autogenous mill for grinding.
3. Cyclone feeding: The ground slurry is pumped to a hydraulic cyclone at a certain pressure and flow rate for classification treatment (separating coarse and fine particles).
4. Tailings transportation: This is the most classic application of slurry pumps. Transport the discarded tailings slurry after beneficiation over long distances to the tailings pond for storage. This is one of the scenarios that requires the highest durability and reliability of the pump.
5. Concentrate transportation: Transport valuable high concentration concentrates (such as iron concentrate, copper concentrate, gold concentrate) to the filtration or dewatering workshop after selection.
6. Sludge cleaning: Clean up the accumulated slag and sludge on the workshop floor and equipment bottom.

Ⅱ、 Electric power industry

Specific scenario:
7. Coal fired power plants - flue gas desulfurization (FGD) system: used for circulating and pumping limestone or gypsum slurry to absorb sulfur dioxide in the flue gas. This scenario requires the pump to have excellent corrosion and wear resistance performance.
8. Coal fired power plant - ash and slag removal system:
Ash conveying: The slag (bottom slag) generated at the bottom of the boiler and the fly ash collected by the dust collector are mixed with water and pumped to the ash yard.
Stone coal emissions: Waste materials (stone coal) discharged from coal mills during transportation.

Ⅲ、 Metallurgical industry

Specific scenario:
9. Steelmaking continuous casting/hot rolling process: Transport circulating water for cooling and purification, which contains a large amount of iron oxide scale (iron oxide chips).
10. Wet metallurgy: In the wet smelting process of metals such as copper, zinc, nickel, cobalt, etc., various corrosive leaching solutions, extraction solutions, and electrolyte slurries are transported.

Ⅳ、 Coal industry

Specific scenario:
11. Coal washing and processing: in the whole coal washing plant, it is used to transport raw coal slurry, middling coal, gangue and circulating water. The slurry pump is a key equipment for separating coal and impurities.
12. Coal slurry water treatment: a mixture of fine coal slurry particles and water generated during the transportation and washing process.

Ⅴ、 Dredging and River Management

Specific scenario:
13. River and port dredging: Installed on dredgers, it is used to extract sediment and silt from the bottom of rivers, ports, and lakes, and transport them to designated areas through pipelines. This scenario typically uses a slurry pump with a large flow rate.
14. Hydraulic reclamation: Pump the dredged sediment to the area that needs to be reclaimed, creating new land.
15. Reservoir dredging: Remove sediment from the bottom of the reservoir to restore storage capacity.

Ⅵ、 Building Materials and Ceramic Industry

Specific scenario:
16. Sand and gravel factory: Transport the mud water generated during the flushing process of sand and gravel.
17. Preparation of ceramic raw materials: Transport slurry of raw materials such as kaolin, clay, quartz, etc.
18. Cement production: conveying raw material slurry or processing kiln ash, etc.

Ⅶ、 Chemical and other industries

Specific scenario:
19. Alumina production: Transport high-temperature, highly abrasive bauxite slurry and red mud.
20. Phosphate fertilizer production: Transport highly corrosive phosphate slurry and phosphogypsum.
21. Salt Lake Lithium Extraction: Transporting highly corrosive salt lake brine.
22. Urban sewage treatment plant: used to treat sludge from primary and secondary sedimentation tanks, as well as to transport raw sewage containing a large amount of impurities (inlet pump station).

Summary

The core application scenarios of slurry pumps can be summarized as follows: they are almost everywhere that requires long-distance, high flow, and high head transportation of slurry containing solid particles. Its value lies in the ability to continuously and reliably handle media that are destructive to ordinary water pumps, and it is an indispensable "artery" in the production process of the heavy industry sector mentioned above.
