Special Application Bucket Elevators

These bucket elevators are designed for gently handling seeds, grain, oilseeds,
pulses and similar products where degradation of the seed
and damage to the germination quality of the material
is to be avoided. The bucket elevators are also ideal for
incorporation within the rice milling, maize milling,
rice drying, maize drying and similar cereal grain
and seed processing applications where attritional product
damage is to be minimized and where cross-contamination
 is prohibited.

Pneumatic Conveying Units

The vacuum conveyor is designed for industrial applications incorporating heavy-duty components and is the ideal transfer equipment, used for transporting powder and granular materials for feeding the materials directly into mixers, sifters and other processing equipment. It reduces the likely dust emissions and is GMP certified. It is widely used in the pharmaceutical, foodstuff, feedstuff, chemical and plastics industries and for general processing material handling applications. The capacity range is from 0.4-6 metric ton per hour.

Working Principle:

The vacuum conveyor consists of a vacuum unit (no oil, no water), feeding tube, PE filter, vacuum hopper, automatic control device, pneumatic discharging device and a compressed air pulsing unit.

The ZKS conveying units have the characteristics of low power consumption high capacity, low noise and reliable operation. It is the ideal type of equipment for transferring powder and granular materials to mixers and processing equipment including sifters, packers, reactors etc.

Note:

-Pneumatic receiver to be placed above hopper.
-Vacuum unit on the floor beside hopper
