The Applications of Drum Granulation Equipment:
Any process that aggregates finely divided materials into larger
entities can be called a granulation process. In different
industries, this operation has different terms, such as
spheroidization, granulation, powder pressing, and so on. Although
pulverization can also make large materials into granular materials
with a certain size distribution, this is the reverse process of
granulation.
The Advantages of Drum Granulation Equipment:
The use of granular materials instead of fine powder materials, in
many industrial applications, can generally achieve greater
benefits:
1. Reduce material loss (such as powder compaction);
2. Reduce the harmfulness of irritating fine powder materials
(flaky caustic soda);
3. Improve the fluidity of materials (ceramic and clay granulation
feed);
4. Increase the loose packing density of materials to facilitate
storage and transportation;
5. prevent the formation of solid blocks (fertilizer granulation);
6. Convenient for metering and batching, quantitative packaging and
taking (tablets, synthetic resin, furnace feed);
7. Convenient to form a solid mixture (feed, sinter ore) without
west west blending;
8. Convenient to control product properties, solubility, porosity,
specific surface, etc. (food, catalyst, adsorbent);
9. Improve the appearance of the product and obtain the desired
structural shape (food, workpiece);
10.Multi-component powder separation (selective agglomeration of
pulverized coal).

Drum Granulation Equipment Working Principle:
The drum granulator is composed of under frame, cyclinder, driving
device, support & catch roller, coupling shaft etc. The chain
wheel drive support & catch roller by reducer at working, the
inclined cycliner slow rotating by support & catch roller under
the friction force, the mixed material risen through the cycliner
wall by friction force and centrifugal force, then rolling down by
gravity. It will rolling into a ball by relative movement betwenn
the rolling down material and rising material, the balls moving to
the lower side from higher side along cycliner axis when the balls
rolling along the circumference, then the final grain discharged at
lower side.
