Vacuum conveying provides for a non electrical , non mechanical, ATEX approved means of moving product up to
100 metres with no dust. It is suited to any environment in the process industries. When used in conjunction with the
Sievmaster vacuum sieving units, it is second to none in giving the user complete control over hazardous or dusty
materials that can cause harm to operators. A brief description of how the system works is below please click on the
Sievmaster link above to see how we have installed this simple system into many facilities.
A) Suction point - the place or machine, where the material is taken from to be transported, e.g. silo, FIBC / IBC, granulator, dryer, loading hopper, manual suction lance etc.
B) Vacuum Conveyor
C) Product Unloading Point - the place or machine, to which the material is conveyed or fed into, e.g. reactor, Big-Bag, mixer, press, container, bag filling machine
Vacuum conveyors transport powder, dust, pigments, granulated material, tablets, capsules, small parts etc. in a suction air stream under vacuum through hoses or pipes. They are easy to install and to operate. Even if leakages occur, no product can get into the environment because of the vacuum.
1. The vacuum pump generates a vacuum in the Vacuum Conveyors separator tank. Air rushes in through the hose/pipe and the suction inlet from the feeding point . The bulk material is aspirated and then carried in this air stream.
2. Inside the separator tank a filter module separates air and product. The transported material is kept and collected in the separator. With fine dust a cyclone element inserted into the separator provides higher transportation capacities because of a lower load of the filter elements.
3. When the separator is filled with product, the vacuum pump switches off, inside of the vacuum conveyor the pressure is balanced to surrounding area within tenths of a second. The separated material discharges from the vacuum conveyor through the discharge element and falls directly into the unit or tank to be charged.
4. Along with the discharging the filter module is cleaned automatically by an air shock system. The occasional filter cake is released from the filter unit. We can offer piston vibrators and fluidizing units to improve the discharging for sticky or highly bridging bulk materials.
5. After unloading the product the discharge element closes and the whole conveying cycle starts again.
