Shandong Ningye Machinery Equipment Co., Ltd. is one of the leading manufacturers and suppliers of large-scale thickener in China. With a professional production team, we are able to meet the needs of the majority of our customers. Please feel free to buy durable large-scale thickener at low price from our factory.
As a professional manufacturer of large-scale thickeners, we rely on mature production processes and R&D capabilities to create efficient, stable and energy-saving large-scale thickeners suitable for large-scale industrial production. The Large-scale Thickener is a core equipment for solid-liquid separation and concentration of materials such as slurry and sludge, based on the principle of gravity sedimentation. It can improve processing efficiency, reduce costs, and provide customers with integrated standardized and customized solutions.
A large-scale thickener is a large-scale solid-liquid separation equipment based on gravity sedimentation. It can concentrate suspended materials with a solid content of 10%-20% into underflow with a solid content of 45%-75%, and separate qualified overflow liquid at the same time, realizing material recovery and environmental protection discharge.
The product is widely used in fields such as ferrous metal beneficiation, non-ferrous metal beneficiation, coal washing, hydrometallurgy, chemical industry, environmental protection, and extraction of strategic minerals such as lithium, cobalt and nickel. It is suitable for the large-scale continuous production needs of customers such as large mines and metallurgical plants.
Product Structure Composition
The large-scale thickener has a scientific structure, and its core components are made of high-reliability materials and precision processing to ensure long-term stable operation. The main structures are as follows:
Tank Body:
Cylindrical cone-bottom structure, the material can be carbon steel, stainless steel or concrete according to the material characteristics. The cone bottom inclination angle is 6°-12° to prevent silting; the diameter can be customized, up to 58 meters, suitable for different production scales.
Transmission Device:
There are two types: central transmission and peripheral transmission, which can be selected according to needs; it adopts high-efficiency reduction motor and precision transmission mechanism, with low energy consumption and stable operation, and the rotating speed is 1/3~1/5r/min to ensure stable operation of the rake arm.
Rake Arm and Rake Teeth:
Made of wear-resistant composite materials, the cross-shaped rake arm is matched with 30° inclination rake teeth, which can fully scrape the underflow material; the key components are treated with wear resistance and corrosion resistance to extend the service life.
Feeding and Overflow Device:
The feeding well is optimized by CFD to ensure uniform material distribution; the annular overflow weir ensures stable discharge of overflow liquid, and the solid content of overflow liquid is ≤300ppm, which can be directly recycled.
Underflow Device:
Located at the bottom of the tank, equipped with underflow pump and flow regulating mechanism, which can accurately control the discharge speed and concentration; some models are equipped with underflow circulation and flushing functions to prevent blockage.
Control System:
Standard configuration of PLC automatic control, integrated with various sensors, real-time monitoring of operating parameters, automatic adjustment of relevant working conditions, can be connected to the customer's DCS system, supporting remote monitoring and data recording.
Working Principle
The large-scale thickener works based on the gravity sedimentation of solid particles, and the specific process is as follows:
Feeding Stage:
Suspended materials enter the feeding well through the feeding pipe, and are evenly distributed to the sedimentation area after shunting, avoiding impact on the sedimentary layer.
Sedimentation and Concentration Stage:
The materials are static in the tank, and the solid particles settle by gravity to form a sedimentary layer; adding flocculant can accelerate coagulation, and the unit area processing capacity is 15%-30% higher than that of traditional models.
Solid-Liquid Separation Stage:
The rake arm scrapes the deposited materials at the bottom to the underflow port for discharge, and the upper clear overflow liquid is discharged through the overflow weir to complete solid-liquid separation.
Intelligent Regulation Stage:
The control system collects parameters in real time, automatically adjusts working conditions, ensures stable underflow concentration and up-to-standard overflow, and realizes fault early warning and less manual intervention.

Core Performance Advantages
As a manufacturer, we optimize from the aspects of material, process and technology. The core advantages of the product are as follows, which are in line with the customer's production needs:
High Processing Efficiency:
Large single-machine processing capacity, the unit area processing capacity is 3-5 times that of ordinary models, and the efficiency is increased by more than 40%; flow field optimization and precise flocculant control further shorten the processing cycle.
Energy Saving and Consumption Reduction:
Optimized transmission and motor configuration, energy consumption is 10%-20% lower than that of traditional models; independent patented feeding dilution technology reduces flocculant dosage and operating costs.
Environmental Protection Compliance:
The overflow liquid is clear and can be recycled or discharged up to standard, and the underflow concentration is stable for subsequent treatment, which is in line with environmental protection policies and the "double carbon" goal.
Convenient Maintenance:
The top bridge is equipped with a hoisting channel, and the underflow system is designed to facilitate the replacement of accessories; remote fault diagnosis reduces maintenance workload, and vulnerable parts have strong versatility.
