Refinement of Materials and Products of Complex Configuration


Pneumoimpulsive installation is aimed at refinement of details of complex configuration. The key element of the equipment is impulsive pneumoacoustic radiator which should inject compressed gas into gas or liquid media in order to excite acoustic oscillations. Acoustic oscillations perform effective refinement of both outer surface and inner cavities and blind holes of the product up to 1mm in size. The refinement of items is mostly carried out without heating of the cleaning liquid.

Parameters of pneumoimpulsive installation:

  • Power source – 220 V, 50 Hz;
  • Volume of cleaning chamber – 30-500 l;
  • Power consumption of pneumoradiator – 50 W;
  • Power flow per 1kg of the refined products;
    • with water heating - 50 kJ;
    • without water heating – 15 kJ.

Innovative Aspect and Main Advantages

  • combines several technological activities (washing and refinement, wringing, drying) in one installation;
  • reduces power consumption due to the absence of stable operation and usage of the pulsed operation;
  • reduces the time of refinement;
  • increases the quality of refinement of the items of complex configuration with blind holes, inner cavities or channels;
  • reduces the cost of refinement;
  • makes it possible to refine not only the items of complex configuration but also dispersed materials (silica and molding sand, feldspars);
  • does not require usage of chemicals.

Areas of Application

  • Machinery engineering: refinement, washing and degreasing of the items from organic and non-organic contaminants.
  • Service: cleaning and washing of clothes, fabrics, furs.
  • Ore-dressing and processing field: dis-ironing of silica and molding sand, feldspars.

Stage of Development

Experimental-industrial model: experience of the installation application for industrial use.
