GZL Series high output rolling granulator without any additive
Brief introduction
GZL Series high output rolling granulator without any additive is mainly used to make irregular granules directly from powder of
which the moisture content should be less than 10%. Without adding
any adhesive, the dry powder will be rolled/ pressed into flakes by
two rollers. Then the flakes will be crushed and sieved to make the
qualified granules. Because the dry powder is mechanically rolled
into flakes, the density of the granule products will increase 1.5
to 3 times than the powder.
Operation principle
The dry powder will be fed into the feeding hopper. After being
degassed and compacted, the fed material will be mechanically
introduced into two equal-sized rollers which are counter rotating
by screw feeder. The counter-rotating roller will press the
material into flakes. The flakes then will drop into a crusher
which will grind the flakes into irregular granules. A sieving
machine fixed at the bottom of the granulator will sift the
granules to sort out the qualified granules. The unqualified
granules will be re-granulated. The pressure needed for rolling can
be regulated through the hydraulic system.
Features
1. the feed dry powder is mechanically rolled into required shape
without any adhesive, so the purity of the product can be
guaranteed.
2. Direct granulating from dry powder make the next drying process
unnecessary which can considerably reduce the investment and
operation cost.
3. the bulk density of the granules can be considerably increased.
4. the scope of application is broad and the density of the product
can be easily regulated.
5. the machine is compact and convenient to operate and maintain;
the process flow is efficient and simple; energy-saving and low
failure rate.
6. the environment-friendly operation condition can considerably
increase the powder usage rate and save the cost for packaging.
7. the whole granulating process is conveniently controlled through
the control panel.
8. the main transmission parts are made by high-quality alloy which
can considerably extend the life-span.
