Inclined Plate Thickener

Product Introduction

The Inclined Plate Thickener is an efficient gravity thickening device designed with inclined parallel plates in the sedimentation zone. It is specifically engineered for the clarification and thickening of flotation tailings and is also suitable for processing various slurries containing solid fine particles, demonstrating its broad applicability and flexibility. Its unique inclined plate channel design not only enhances thickening efficiency but also ensures the long-term stable operation of the equipment.

Advantages and Features

Integrated Channel Design

Each sedimentation channel of the Inclined Plate Thickener integrates feeding, grading thickening, sand discharge, and overflow functions. This unified structure ensures stability and consistency across all grading and thickening channels, enhancing overall operational efficiency.

Modular Inclined Plate Sets

By combining and integrating identical inclined plate modules, the total settling area of the equipment can be flexibly adjusted. This allows for scalable equipment designs to meet different production needs.

Customizable Inclined Plate Channels

The inclined plate channels can be designed to accommodate variations in slurry properties and grading particle sizes, ensuring optimal performance under different operating conditions and improving processing effectiveness.

Automatic Cleaning and Anti-Blockage

The inclined plate modules use intermittent high-frequency micro-vibrations for regular automatic cleaning, preventing material buildup and inter-plate blockages. This feature ensures long-term stable operation of the equipment.

Efficient Material Removal and Discharge

A special material removal device within the thickening cone avoids material accumulation. It allows for high-concentration underflow discharge, with concentrations reaching up to 270%, meeting the requirements for concentrate and tailings dry discharge and enhancing resource utilization.

Multi-Functional Applications

The Inclined Plate Thickener is versatile, suitable not only for thickening and water recovery but also for classification and desliming. When combined with flocculant pre-treatment, it can function as a high-efficiency thickener, showcasing its multifunctionality and flexibility.

Working Principle

The Inclined Plate Thickener consists of an upper tank and a lower cone. The upper tank houses an array of inclined plate sets, which are made up of multiple independent inclined plate units.

Material enters the inclined plate units from both sides at the bottom. The overflow weir located above the inclined plate sets features throttling orifices that create a hydraulic back pressure for the external overflow, ensuring uniform loading across the inclined plate units and preventing radial turbulence.

The side-fed, semi-counterflow feeding method allows the descending solid particles and ascending clarified liquid to flow separately without interference. The thickened slurry sliding down the inclined plates enters the lower cone, where it undergoes compression and dewatering. The dewatered material is then discharged either by gravity or with mechanical vibration assistance.

The thickening process occurs within each individual inclined plate channel. Fine particle overflow or clarified water is directly discharged laterally from each channel’s overflow surface, shortening the overflow discharge path. This design effectively prevents fine particle short-circuiting and recycling issues, ensuring high grading and thickening efficiency. The water recovery rate typically exceeds 70%, significantly enhancing the overall performance of the equipment.
