Pneumatic low-velocity conveying |
| |
 Newly introduced, this innovative system conveys materials with a fragile size and / or shape, all of which were previously thought to be too difficult for pneumatic conveying. Depending on the form and structure of the bulk product, feeding demands special attention. This method of conveying allows for metered feeding. Lumpy bulk materials are conveyed in the suction stream into the receiver by the vacuum generated, then gently separated and emptied. The separator is often designed as a cyclone, using a secondary filter upstream of the vacuum generator, and demand sensor for demand signaling. |

Advantages |
| |
  Gentle conveying of fragile bulk materials
Conveying without destroying sensitive particle structure
Feeding of filling machines without increase in bulk weight
Conveying of heat-sensitive products without damage |
|
| |
Best for conveying |
| |
Frozen vegetables, onion rings, mushrooms, noodles, sweets, nuts, tea, chocolate chips, tablets, capsules, pellets, plastic mouldings, bottle caps, electronic parts etc. |

Pneumatic
semi-dense phase conveying |
| |
 Ideally
suited for batch or continuous feeding of processing machines with powdery, particularly light or abrasive
products. Wave-like conveying occurs, caused by accumulation of the
product in the lower half of the pipe. For gentler conveying, the
velocity can be reduced to almost the saltation point. |
|
| |
Advantages |
| |
 Very gentle conveying solution for product and pipe
Optimum line loading for the respective conveyed product
Dust-free process
Automatic demand and level control |
|
| |
Best for conveying |
| |
Styrofoam, aerosil, glass-fiber reinforced granules etc. |
|
| |
Pneumatic
dense phase conveying |
| |
 This is most gentle method of pneumatic conveying. It is especially suited for batch of continuous feeding of processing machines with moist, high-fat content bulk materials that tend to stick together with finished mixtures, or delicate particle structures, or very fine and light products. At the feeding point (sack, barrel, container, or silo) the conveyed product is transferred by means of timed air impulses through the conveying line and into the receiver in which product slugs and air cushions alternate.In the receiver, the conveyed product is gently separated from the conveying air, and emptied into the downstream processing machine. A level sensor on the machine hopper functions as the demand signal. The filter cleans itself automatically. |
|
| |
Advantages |
| |
Extremely gentle and segregation-free
Highly energy-efficient due to low air and product speed
No abrasion and destruction of particle structure
Optimum line loading to the respective conveyed product |
|
| |
Best for conveying |
| |
Milk powder, cocoa, cosmetic mixtures, baking mixtures, instant powders, carbon black, aerosil etc. |
