 What is the sand used in water purification systems? The sand used in water purification systems to filter out impurities is often called quartz sand or quartzite sand. Quartz sand is a siliceous mineral that has become one of the important filter media in water purification systems due to its high hardness, strong corrosion resistance, high density and stable chemical properties. What is the role of quartz sand in water purification systems? The quartz sand in the water purification system is mainly used to filter suspended solids, particulate matter and turbid substances in the water to ensure the safety and hygiene of drinking water. Quartz sand has the characteristics of large volume, high porosity, strong pressure resistance, and strong ability to capture pollutants. It can effectively remove impurities in water and make the water clear and transparent. https://www.lzzgmachine.com/service-parts/product-knowledge/what-type-of-sand-is-used-in-water-purification-systems.html

  Artificial sand is generally stored and dehydrated for 3 to 5 days to reduce the water content to within 6% and become stable. The artificial sand and gravel powder content varies depending on the initial moisture content. Generally, the stone powder content is in the range of 10% to 17%. When the initial moisture content of wet sand is 15% to 17%, the dehydration speed is fast within about 48 hours in the initial stage. Generally, the moisture content can be reduced to 8% to 10%. When the moisture content drops to 8% to 10%, it can be reduced to 6%. The dehydration speed slows down significantly around %, generally taking 3 to 5 days. Based on the daily production of 15,000 tons of finished sand and the daily sand consumption of 1 to 15,000 tons, the finished sand warehouse has a storage capacity of 50,000 m2, and the natural dehydration time is about 5 days. Measures to effectively control the  moisture content of artificial sand  in stacking sand bins 1. In the general system proc

  Dry sand making is a machine-made sand production process. The raw materials are sent to the crusher through the feeder for crushing. The raw materials are crushed to less than 5 cm and sent to the sand making machine for sand making. After the sand making machine, the raw materials are crushed into sand grains of less than 5 mm and transported. machine to the finished product pile. The production process does not require water. It mainly removes powder through negative pressure in the dust box or positive pressure in the powder separator or a combination of the two. It uses wind to remove powder, so that the powder content of the machine-made sand is low, and the dust will also be removed. Collected as a by-product, dry sand making is suitable for areas with severe water shortages. Dry machine-made sand has many advantages 1. To save water resources, sand plants can be built in areas lacking water resources. 2. The finished product has low moisture content. 3. The process is simple

 Recently, customer-customized sludge separation equipment was produced and delivered. It was sent to the Xinjiang oil field project site to help the customer’s project construction steadily advance. The R&D personnel of Longzhong Heavy Industry integrated the existing oilfield sludge treatment technology and developed a set of oilfield oily sludge separation equipment based on the actual situation of the customer’s project. The system uses scrubbing machines to fully stir and disperse, centrifugal separation, dehydration recovery and other technical processes to effectively separate the various phases in the oily sludge, truly realizing the four-phase separation of oil, mud, sand and water, and at the same time reaching the relevant national standards. Emission standards also generate economic benefits for enterprises.

Equipment in all aspects of domestic waste incineration slag treatment : iron remover, silo, crushing equipment, magnetic separation equipment, gravity equipment, gravity separation equipment, screening equipment, slag finished product collection tank, sedimentation tank, etc. Utilize the potential energy of gravity, use water as the medium and circulating flow, and set the equipment vertically from high to low; inject water and waste incineration slag into the crusher to form a material flow. Under the action of the gravity flow of the material, it passes through the crusher equipment, gravity equipment, and screening Equipment to obtain slag materials with fine particles, light weight and optimized components. After filtering through the collection tank and sedimentation tank, the dried fine-grained slag products are directly transported to the finished product warehouse; the clean water after sedimentation and filtration is again incinerated with garbage. The slag raw materials are
