1. Introduction to High-pressure Roller Ball Press
The high-pressure double-roll ball press, manufactured by Zhengzhou
Tianci, is a specialized piece of equipment engineered to compress
powdered raw materials into dense, solid pellets.Its industrial
applicability is exceptionally broad. It is capable of processing a
diverse range of raw materials—including aluminum turnings, activated carbon, alumina, bauxite,
caustic soda, charcoal, clay, coke breeze, coal, cryolite, chemical
fertilizers, plastic powder, limestone, pigments, urea, and
potassium fertilizers—for agglomeration, granulation, and briquetting purposes.

The core value of this equipment lies in its practicality: it
minimizes dust emissions, optimizes the bulk density of raw
materials for precise output regulation, enables raw material
recycling and reuse, and streamlines raw material transportation.
Tailored to specific process requirements, it is primarily used to
compress dry powder raw materials into pellets with a diameter of 3
millimeters or larger. The pellets produced exhibit consistent
forming quality, meeting the subsequent production and application
demands of various industries.
2. raw materials and materials used in briquetting
2.1 Applied raw materials
Aluminum chips, activated carbon, alumina, bauxite, caustic soda,
charcoal, clay , coke chips, coal, cryolite, fertilizers, plastics, limestone,
pigments, urea, potash salt...
2.2 Material requirements
2.2.1 The particle size of the material can be between 30 and 200 mesh.
2.2.2 Hard metal objects are not allowed in the material, otherwise the
roller surface will be damaged.
2.2.3 The material supply must be sufficient. It is advisable to use an
adjustable speed screw feeder and adjust the supply of new material
by observing the return material volume.
3. Brief description of working principle
The pre-pressed material discharged from the pre-pressing screw is
forced into the central area of the rollers via the ball-pressing
nozzle. The rollers, operating at equal rotational speed but in
opposite directions, apply compressive force to the material.
During this process, the unit pressure acting on the material
increases progressively, peaking at the line connecting the centers
of the two rollers. As the material passes this center line, the
unit pressure decreases gradually, inducing the material to enter a
pellet-dropping phase until the pellets are fully discharged.
With proper adjustment of the main machine speed and pre-pressing
speed, the equipment can achieve one-step pellet formation. When
the screened return material is mixed with fresh material for
re-pressing, the return material must be free of excessively large
lumps; it is recommended to crush the return material into
particles of 2-3mm in size. In cases where oversized lumps are
present in the return material, or the proportion of return
material in the return-fresh material mixture exceeds 50%, the
rotational speed of the pre-pressing screw shall be reduced.
Failure to do so will likely result in motor overload.
