The Kermetico Mini-Air Powder Classifier (Metal Powder De-Duster) For A Thermal Spray Shop
Classification Equipment to De-Dust Metal Powders for
Thermal Spray and Laser Cladding
The Kermetico Mini Air Classifier (MAC) separates fine particles or dust from the rest of the powder batch.
It is a simple, economical and efficient system to:
a) clean the powder of unwanted fines (for instance, in thermal spraying or powder metallurgy)
b) separate small-size particles (1 –20 microns)
A Principle Of Operation Of The Powder de-Duster
In the tower of the MAC, powder flows through a number of sloped plates by the force of gravity.
A controlled amount of air flows in the opposite direction (upstream), catching the fine particles and carrying them out of the tower to the cyclone of a dust collection system.
The air flow rate controls the size of separated particles.
The balance of the powder falls down into the steel bucket under the tower.
The air flow rate is controlled by a flowmeter.
An electromagnetic shaker provides stable and even flow of the powder through the de-duster.
A ball valve under the feeding hopper controls the rate of powder feeding into the MAC.

Our main business – designing and manufacturing HVAF and HVOF thermal spray equipment to improve a thermal spray job shop profitability. Please take a moment to review the following HVAF information.
The Description Of Our HVAF Process
The Kermetico HVAF (High Velocity Air Fuel) systems spray powders, heated and accelerated by the air-fuel gas combustion products.
When entering the gun, the compressed air cools the chamber and the nozzle assembly.
The mixture of pre-heated compressed air and the chosen fuel gas flows into the combustion chamber through the orifices of a catalytic ceramic insert.
The initial ignition of the mixture results in the heating of the insert above the mixtures’ auto-ignition temperature, and then the hot insert continuously ignites the mixture.
The spray powder is injected axially into a wide combustion chamber. The powder exiting the chamber is propelled into the nozzle of chosen length and configuration, where it is accelerated to a velocity that may be over 1,000 m/s (3,300 ft./sec.) When impacting a substrate, the spray powder particles form a coating.
