Oppressive Balling Machine product description
GGZ series dry high pressure pelletizing machine is the second
generation of dry roller pelletizing machine which is researched
and designed by our company on the basis of absorbing the advanced
technology from abroad. Due to the adoption of dry extrusion and
forced feeding technology, the powdery material with water content
<5% can be compressed into granule shape. It has the
characteristics of high pelletizing rate, good shape of granule,
high strength, less dust, easy cleaning and maintenance. It can be
widely used in medicine, chemical industry, soda ash, fertilizer,
feed, plastic additives, food, cosmetics and other dry powder
granulation occasions. 1,Materials are forced to be compressed
and molded by mechanical pressure, without adding any wetting
agent, product purity is guaranteed.
2, dry powder direct granulation,
without subsequent drying process, more conducive to the
convergence of the existing production process and transformation.
3,High particle strength, the specific
gravity of the pile can be increased by 1.5-3 times, especially
suitable for increasing the specific gravity of the product pile of
occasions.
4,It can control the environmental
pollution, reduce the waste of powder and packaging costs, and
improve the product transportation capacity.
5,Compact structure, easy maintenance,
simple operation, short process flow, low energy consumption, high
efficiency, low failure rate, suitable for a wide range of raw
materials.
Oppressive Balling Machine working principle
Powder material from the hopper through
the spiral feeder quantitatively and uniformly added to the main
hopper, so that it maintains a stable material level, and then by
the longitudinal cone screw machine for pre-compression of the
powder, and sent to the two pressure rollers formed in the molding
cavity; two pressure rollers uniformly distributed on the surface
of the same shape of the mold, through the power transmission, so
that the two pressure rollers at the same speed, synchronization,
phase rotation, the conveyor of the powder is bitten into the
roller cavity forced compression, extrusion, powder After
compression and molding, the powder will fall down under the action
of elasticity and gravity, and a small amount of non-dislodged
material will be scraped down by the scraper. By changing the roll
surface mold form, can get ball, strip, flat ball material,
according to the particle size requirements of the sieve, grading,
meet the quality requirements of the granular products transported
away, sieve the fine powder back to the main material warehouse to
form a closed-circuit cycle of granulation.Oppressive Balling Machine Technical Parameters
