The screw press sludge dewatering machine is a high-efficiency solid-liquid separation device based on the screw extrusion principle. It has been widely used in municipal and industrial wastewater treatment since the 1960s. Working Principle The core principle of the screw press is a progressive dewatering process combining screw extrusion and dynamic/static ring filtration, mainly comprising five stages: Flocculation and Mixing: Sludge is thoroughly mixed with a high-molecular-weight flocculant (such as PAM), causing fine particles to agglomerate into larger flocs. Gravity Concentration: The flocculated sludge enters the concentration section, where most of the free water is squeezed out under gravity within the wider gaps between the rings. Screw Extrusion Dewatering: The concentrated sludge is pushed into the dewatering section. As the screw shaft rotates, the gap between the dynamic and static rings gradually narrows, while the back pressure plate creates mechanical resistance, continuously increasing the pressure on the sludge and forcefully…

Tailings recycling has become an inevitable choice for the high-quality development of the mining industry in various countries. Its necessity is reflected in multiple dimensions such as resource security, environmental protection, and economic benefits, and it is a key measure to "turn waste into treasure and harm into benefit." Our tailings recycling machine was developed to meet this need. It is an environmentally friendly device specifically designed to recover fine sand from tailings or fine sand lost in sand washing wastewater. It can effectively solve problems such as serious fine sand loss, unreasonable gradation, and environmental pollution in traditional wet sand making processes, with a fine particle recovery rate of 85%-95%. The system mainly consists of the following core components: Washing Tank: Collects the sand-water mixture, serving as a buffer and mixing container. Slurry Pump: High-pressure pump that delivers the sand-water mixture to the hydrocyclone; it is the core power source…

This thickening tank is an improvement on the internal feed cylinder structure of traditional vertical flow sedimentation equipment, which greatly improves sedimentation efficiency. The tank body is circular in plan, and suspended solids settle into the conical sludge hopper at the bottom of the tank under gravity. Clarified water is discharged from the overflow weir around the top of the tank. The overflow outlet is equipped with a scum filter and baffles to ensure the quality of the effluent. This thickening tank is a solid-liquid separation device based on gravity sedimentation and chemical action. It can increase the concentration of mineral slurry wastewater with a solid content of 2% to 15% to slurry with a concentration of 60% to 70% through gravity sedimentation and chemical action. At the same time, clear water overflows from the top of the tank, thereby achieving the purpose of wastewater purification and solid-liquid separation.

A hydrocyclone group is a classification and separation device composed of two or more hydrocyclones connected in series or parallel. When a single hydrocyclone cannot meet the required throughput or classification fineness, using a hydrocyclone array can significantly improve the overall performance and is widely used in mining, power, chemical and other fields The hydrocyclone group mainly consists of the following components: Individual hydrocyclone: Each assembly contains several hydrocyclones Grit chamber: Collects coarse particles discharged from the underflow of each hydrocyclone Overflow chamber: Collects fine particles or liquids overflowing from each hydrocyclone Liner material: Selected according to the characteristics of the medium, such as rubber, polyurethane, or high-alumina ceramic Auxiliary components: Including valves, regulators, pressure gauges, feed pumps, etc. Key advantages: Fine particle size classification: Achieves over 80% fine particle size products with a content of -0.074mm (-200 mesh). High classification efficiency: 5-10% higher than traditional spiral classifiers. Large processing capacity: Single…

Center-driven thickeners are solid-liquid separation devices widely used in mineral processing, metallurgy, chemical engineering, and environmental protection. They are primarily used to concentrate low-concentration mineral slurries or liquids into high-concentration underflow, while simultaneously obtaining clarified overflow water.Compared to peripheral-driven thickeners (typically over 53 meters in diameter), center-driven thickeners are more suitable for small to medium-sized applications (usually under 24 meters), featuring a compact structure, simple maintenance, and low investment costs. Advantages: High-efficiency concentration capacity: High throughput per unit area, employing flocculation technology to significantly improve settling speed; hydraulic drive with stepless speed regulation; Multi-point synchronous drive: large equipment uses four hydraulic motors to jointly drive the slewing bearing, ensuring balanced force distribution; Automatic rake lifting protection: when resistance increases or oil pressure exceeds the set value, the rake frame is automatically lifted, and the equipment stops when the shutdown pressure is reached to prevent damage; intelligent control; optimized structural design.…

In the back end of processing operations such as mines, aggregate processing, ceramic raw material processing, silica sand production and processing, and various metal mine tailings, sewage treatment processes are often equipped. However, in the sewage treatment process, it is often encountered that a certain proportion of the catalyst solution is added. Since the entire production process is a continuous operation, it is required that the addition of agents should also be continuous and should be added regularly and quantitatively. The automatic dosing machine was developed to meet this demand. Reduced footprint; local display and low-level pump stop protection; allows for both manual and automatic dosing adjustments; compact structure; safe and convenient commissioning and operation. Fully automatic mixing and dosing saves manpower. Continuous drug supply reduces preparation time and dosage.  

A horizontal screw centrifuge, also known as a horizontal spiral sedimentation centrifuge, is a highly efficient continuous solid-liquid separation device. It separates the solid and liquid phases in a suspension through the centrifugal force field generated by high-speed rotation. Its separation factor can reach 1,000 to 40,000 times that of gravity, making it the preferred equipment for large-volume processing and continuous operation in fields such as mining, environmental protection, and chemical engineering. Working Principle Based on the principle of centrifugal sedimentation, continuous separation is achieved; Centrifugal force field formation: The drum rotates at high speed, and the suspension enters the drum cavity through the hollow shaft; Layered separation: The denser solid particles are thrown to the inner wall of the drum to form a solid ring layer; the less dense liquid phase forms a liquid ring layer inside the solid ring layer; Differential speed discharge: The screw conveyor maintains a…
