Product Detail

Product Introduction:
In practice, some materials are difficult to form and no binders are allowed to be added, which requires a ball press with a higher specific line pressure. Generally, we consider a ball press with a specific line pressure exceeding 20t/cm to be an ultra-high pressure ball press.
Main features:
Compared to high-pressure ball presses, in addition to possessing the basic characteristics of high-pressure ball presses, this series of equipment also has unique features, such as:
1. All motors and reducers adopt a direct connection structure for more accurate transmission.
The application of variable pitch spiral is essential, and the pre pressed spiral effect through precision machining will be better.
3. The sealing technology on both sides of the preloading spiral and the pressure roller is one of the important features of this equipment. Its sealing effect is better, ensuring that the material does not release pressure in a sealed environment under ultra-high pressure conditions.
4. Strengthened the self-control and protection capabilities of the equipment itself from the control system.

Principle of Ball Pressure:
The powdered material is compressed and formed between a pair of rotating pressure rollers, one of which is movable and provides pressure through a hydraulic system. The surface of the pressure roller has a customized mold. The material may be a single or mixed material, or it may require the addition of a certain binder.

Process flow:
The ball forming performance of different materials varies, and the selection of ball pressing machine and process is also different. In addition, the requirements for the final product are also important factors determining the process.
The balling performance of materials depends on the material itself, such as fineness, particle size, moisture content, composition, etc., which usually require testing to determine.
Not all materials have sphericity. If the bonding force between material particles is low, a suitable adhesive is necessary.
According to the physical properties of the material and the purpose of forming the ball, the selection of adhesive needs to be based on its bonding performance and usage cost. Various (liquid or solid) adhesives such as starch, bentonite, asphalt, quicklime, cement, water, flour, lignosulfonates, molasses, polymers, resins, sodium silicate, and new composite adhesives for specific purposes, etc.
The key process of ball pressing equipment is "continuous quantification", so continuous batching, mixing, and subsequent drying steps are usually required in the process (see sample booklet for details on batching and mixing steps).
In practice, Kaizheng Company has accumulated considerable experience and possesses complete turnkey system capabilities (including electrical interlocking and interface control). The integrated system forming unit is used to meet your specific needs.
Note: (The process may vary depending on the material and usage).
