The system is designed for loading, unloading and transporting bulk materials with a particle diameter of 8 mm. VAC® system is operated in conjunction with the abrasive material receiving hopper, connectable to the cascade-type abrasive material separator that is installed on the abrasive jet system model BLASTCOR® BM- 200. For long-term trouble free operation of the filter element in front of the vacuum unit is installed cyclone-type separator (to remove fine dust particles). System components are installed on flat surface with a minimal distance from each other. Suction vacuum hoses are connected with quick connection. Abrasive material is poured into a hopper manually (when installing the vacuum system on the surface, designed for abrasive blasting work), or conveyor system, installed in the chamber for abrasive treatment of the products, which is located above the hopper.
The abrasive material is fed through a suction tube on vacuum hose to the abrasive material cascade separator, where step by step it is cleaned from dust and large particles and falls under gravity in to the receiving cup of the blasting installation. The contaminated air is cleared in two stages. The first stage - a stationary cyclone separator, in which is made pre-cleaning of dusty air from large dust particles and dirt. The second stage – the filter element made of polyester, purifying the air.
Abrasive dust particles and other contaminants that are laying on the walls of the filter element are periodically shaken off with a short pulse of compressed air in the tapered receptacle for collecting dust. On the bottom side of the receiver is installed disc shaped valve with “A” tightness class. After the end of the operation cycle and after turning off the vacuum unit, turn the rotary bolt handle and remove the accumulated dust from the conical receiver.
WARNING: The main parameters that affect performance: the length of the suction hose of a vacuum, number of bends and operator qualification.
