1. Introduction to High-pressure Roller Ball Press
Zhengzhou Tianci Heavy Industry Machinery Co., Ltd.'s high-pressure
double-roller ball press machine is a professional equipment
engineered for compacting powdered materials into dense granules.
It boasts extensive industrial applicability, covering the
agglomeration, pelletization, and briquetting processes of diverse
materials, including aluminum chips, activated carbon, alumina,
bauxite, caustic soda, charcoal, clay, coke breeze, coal, cryolite,
chemical fertilizers, plastic powders, limestone, pigments, urea,
and potassium fertilizers.

The core functional values of this equipment lie in suppressing
dust emission, optimizing material bulk density for capacity
control, facilitating material recycling and reuse, and enhancing
the logistics and transportation performance of materials.
Designed with targeted process requirements, this machine is mainly
used for pressing dry powder materials into granules with a
particle size of 3 mm or above, ensuring stable granule forming
quality and meeting the subsequent production and application needs
of various industries.
In order to meet the requirements of material forming, the
pre-pressing screw adopts an electromagnetic speed-regulating motor
with manual speed regulation. The user can appropriately change the
speed of the pre-press according to the ball forming situation to
achieve the highest ball forming rate and maximum production
capacity. The pressed material is screened by a screening machine,
and the qualified granules on the screen are packaged. The material under the screen can be
returned to the silo to be mixed with new material and then pressed
into granules.
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 material from the pre-pressing screw is forced into the center
of the rollers through the ball-pressing nozzle. The rollers,
rotating at equal speeds and in opposite directions, compress the
material. The unit pressure within the material gradually
increases, reaching its maximum value at the line connecting the
centers of the rollers. After the material passes this line, the
unit pressure gradually decreases, causing the material to enter a
ball-dropping state, until the balls are completely dropped .
If the speed of the main machine and pre-press is adjusted
appropriately, this machine can form in one go. When the screened
material is returned and mixed with new material for pressing,
there should not be too large lumps in the returned material, and
it is better to break it into 2-3mm pieces. Once too large lumps
enter the returned material or the proportion of the returned
material and new material in the mixture is greater than 50%, the
speed of the pre-pressing screw should be slowed down, otherwise
the motor will easily overload.
