ATTRITEC

ATTRITION CELLS MIXER AND AGITATOR

Attritec attrition cells are used to remove contaminants bound to surface of sand. They are most commonly used within circuits producing high-value and high specification sands for industries including glass manufacture / foundries / frac oil production. For example within the glass sand sector Attritec is often used to remove iron contamination on the surface of silica sand particles.

The attrition cells usually find their ideal location before the hydrocyclonic process of the slurry and their applications are as follows:

  • contaminated sites (soil-washing): the soil particles are washed in order to disgregate the contaminants from their surface
  • Pre-flotation treatment of the slurry: the washing of the particles before the flotation process guarantees an increase in the selectivity and a reduction of consumption of reagents
  • Mechanical preparation of minerals
  • Separation of grains of sand from minerals and cement purposes
  • Removal of clay and iron stains from silica sand intended for the glass industry
  • break-up of balls of clay and bituminous material andfor the recovery of valuable minerals which may be present on the sand grains
  • For intensive conditioning, the salt industry (refining), abd for lime slaking

3D VIEWER

Friction is generated by agitators inside the machine. The machine has two or more cells according to the retention time needed to achieve the optimal separation.

Attritec components:

  1. steel plate box
  2. drive shafts made of high resistance stainless steel
  3. double easy removable 
  4. impellers made of wear resistant steel
  5. separation diaphragm between the chambers
  6. replaceable, wear-resistant coating made of rubber sheet
