From the perspective of sludge treatment equipment supply, the equipment supply chain of sludge treatment can be refined and divided into tempering and wall breaking, sludge dewatering machine, conveying equipment, deodorizing equipment, digestion equipment, composting equipment, drying equipment, and incineration equipment according to demand. Among them, the technical content of dewatering machine, conveying equipment, and deodorizing equipment is relatively low, and tends to be general equipment; while the technical content of digestion equipment, composting equipment, drying equipment, and incineration equipment is relatively high, involving the company’s parameter setting for sludge treatment process, engineering experience, etc.; the highest technical barriers are still related technical equipment of tempering and wall breaking. Harmlessness and stabilization are the basic requirements of various treatment technologies, and the method is incineration and subsequent treatment of f

The LX SERIES spiral sand washing machine also named sand screw, screw sand washer, which was designed to provide bigger capacity and higher cleaning level than traditional ones. The input materials’ max size can be 30mm. Widely used for cleaning materials in the quarry, minerals, building materials, transportation, chemical industry, water conservancy and hydropower, cement mixture station and so on. They are ideal for construction sand producers, mining companies, salt/brine reclamation, and glass recycling. It is composed of the electric motor, big and small belt pulleys, triangle belt and gear reducer. The screw sand washer adopts inclination of 15 degrees. Under the water tub, three weir plates form the sediment pool. The spiral head is immersed in this pool, and the spiral is driven by electric motor through reducer rotating continuously. The fresh water is fed from porous plate at bottom of sediment pool, and the washed sand is discharged on the top side and delivered by belt c

For concrete cohesion, they believe that if there are fewer particles <0.075mm in the sand, the concrete will easily bleed, and the mixed concrete will be relatively dry and astringent. Therefore, the appropriate content of <0.075mm particles has certain benefits for the cohesion and water retention of concrete. When the mud content is 5% of the sand mass, the workability is good, but when it reaches 10%, the bleeding of concrete is more obvious. The mud content not only has some effect on the initial slump of concrete, but also has a great harm to the slump loss of concrete over time. In the absence of admixtures, it is generally believed that when the mud content in the sand is <3%, the workability of the concrete is less affected, but as the mud content increases, the slump of the concrete continues to decrease. When it is greater than 3%, the workability of the concrete will be greatly affected. https://www.lzzgmachine.com/service-parts/product-knowledge/retaining-fine-par

Tin oxide ore is one of the main sources of tin. Tin ore resources mainly include cassiterite (SnO2) and tin sulfide ore, while tin oxide ore mainly refers to cassiterite. Cassiterite is a mineral that is widely mined due to its relatively high tin content, generally in the form of quartz veins, pegmatites or placers. The best beneficiation method is to combine different beneficiation technologies to adapt to the characteristics of different ores, maximize the recovery rate of tin and reduce costs. The following are some beneficiation methods for tin oxide ore: Gravity separation: Due to the high specific gravity of cassiterite, gravity separation is a common method for separating cassiterite. Cassiterite can be effectively separated from light minerals through equipment such as jigs, shaking tables, spiral chutes, etc. Gravity separation is simple, low-cost, and suitable for coarse and medium-sized ores. https://www.lzzgmachine.com/solutions/beneficiation-methods-for-tin-oxide-ore.htm
