Thickeners are widely used in metallurgy, mining, coal, chemical, building materials, environmental protection and other industrila sectors for sludge, wastewater, and waste residue treatment. The thickener is a solid-liquid separation device based on the action of gravity sedimentation. Usually, a cylindrical shallow groove with a conical bottom is constructed from a concrete, wood, or metal welding plate as a structural material. The slurry with a solid content of 10% to 20% can be concentrated by gravity sedimentation into an underflow slurry with a solid content of 45% to 55%, with the aid of a slow-moving (0.19 to 1.1 r/min) crucible installed in the thickener. The thickened bottom slurry is discharged from the thickener bottom.
2. Pressure Filter
The pressure filter utilizes a special filter medium to exert a certain pressure on the material so that the liquid is leached out. It is well known as a solid-liquid separation device and widely used in metallurgy, gas, paper, coking, pharmaceutical, food, brewing, ceramics and environmental protection industries.
The pressure filter has the advantages of high press pressure, good corrosion resistance, convenient maintenance, safety and reliability. The pressure filter has been widely used in various fields requiring solid-liquid separation.
3. Rotary Disc vacuum Filter
The disc vacuum filter is a group of discs formed by some fan-shaped plates. Each fan-shaped plate is a separate filter unit, made of a filter fabric covering the plate to form a filter chamber. It is widely used in copper, iron, gold, silver, tin, aluminum, lead, zinc, nickel, cobalt, palladium, molybdenum, chromium, ingot, sulfur, phosphorus, coal, silicon, quartz, mica, tin and other concentrates, tails Mineral dehydration and so on.
