Product Overview

The cyclone for alumina is aiming at the classification of alumina industry. In view of the harsh working environment of high temperature, high alkali and strong abrasion in alumina industry, Haiwang adopts wear-resistant rubber, high aluminum ceramics and wear-resistant polyurethane materials, and combines the latest production process, to develop and produce: bauxite grinding classifying cyclone, aluminium hydroxide crystal seed separating cyclone, red mud concentration, sand removal and iron separating cyclone. Haiwang alumina cyclone is the preferred equipment for alumina industry classification with the virtue of its material characteristics and mature processing technology.

Technical characteristics

• The improved involute feeding chamber and spiral feeding chamber structure, single cone angle and multi-cone angle structure are used, which has the advantages of large processing capacity and high classifying efficiency.
• Wear resistant rubber, high aluminum ceramic and wear resistant polyurethane material can be selected, which can take into account the wearing and grading performance under different operating conditions. The best materials are optional according to different operating conditions with long service life.

Application

Raw Material Grinding Classification Cyclone

• Used for the raw material grinding classification of bauxite and tribauxite.
• Adopting the improved involute feeding chamber and spiral feeding chamber structure, the hydrocyclone has large processing capacity and high classifying efficiency.
• The overflow particle size of cyclone is fine, and the amount of fine sand returned is small, which is beneficial to improve the classifying efficiency.
• Wear resistant rubber and high alumina ceramic materials can be selected. The best materials can be chose for different working conditions.

Aluminium Hydroxide and Crystal Seed Classifying Cyclone

• Used for the aluminum hydroxide classification and aluminum hydroxide crystal seed classification in alumina plant.
• With the improved involute feeding chamber & spiral feeding chamber structure, and dual-body cyclone structure design, the cyclone has large processing capacity and high classifying efficiency.
• Solids content in the underflow of cyclone is high, fine particles in the underflow is small and the yield is high.
• Wear-resistant polyurethane material is used, with lightweight structure, high machining accuracy and good wear-resistant performance. The launder flow passing component is lined with wear-resistant rubber and make the lifespan longer than 10 years.
• The humanized cyclone platform operation is easy for valves ON/OFF and reducing slurry splashing.

Red Mud Concentrating, Sand Removal and Iron Classifying Cyclone

• The red mud concentrating and sand removal cyclone can reduce the treatment capacity of concentrator and optimize the feeding conditions of centrifuge and filter.
• The red mud iron classifying cyclone can further classify the coarse product and concentrate product in the red mud iron separation process and improve the separation index.

Wear-resistant Piping, Elbow and Lining Products in Alumina Plant

• The wear-resistant products adopt a unique molding process with a variety of liner material selectable. According to the specific environment of the site, different types of liners for cyclones, elbows, pipelines and flow passing containers with large area can be made, thus to ensure the production indicators at site.
