Cyclones

One of the ways to increase the efficiency and profitability of production when using powder coating is the recovery (return) of powder paint carried away with the flow of ventilation. It is known that in the best case only 60-70% of the paint is deposited on the product from unused 30-40%, only a smaller part remains on the walls and bottom of the spraying chamber, and the main part of the unused paint is carried away by ventilation. Given the high cost of paint, it is not difficult to calculate the economic effect of the use of recovery.

One of the main recovery methods is the use of CYCLONS. The recovery of paint is carried out by centrifugal forces in the upper cylindrical part of the cyclone and the deposition of powder in the lower part of the cyclone. Properly designed cyclone allows you to collect up to 90% of the airborne paint with a particle size of more than 1-2 microns. The use of exhaust filters after the cyclone allows you to return the cleaned air directly to the workshop, which positively affects the savings of heat carriers for heating in the winter, given that the approximate air flow rate for a two-post spraying chamber is 8-12 thousand cubic meters per hour.

It is worth noting that, along with the high efficiency of cyclones, they also have a number of disadvantages. One of the drawbacks is the difficulty in cleaning the air ducts and the cyclone itself when changing colors. The solution to this problem is to use the shortest possible air ducts with the possibility of opening the air ducts for dry and wet cleaning, and the device of hatches for such cleaning on the cyclone itself.

The specialists of our company will help you to correctly calculate and manufacture air recovery and aspiration systems based on the use of cyclones.
