Product Description

 1. Grinding ball production line is mainly used for the production of grinding ball matched with the ball grinding machine (widely applied to mine, cement and power generation industries). In past times, grinding ball production is manually produced. With the development of technology, now the automatic and intelligent production line has gradually replaced the traditional methods and has become the hot research direction to save energy, reduce consumption, reduce labor intensity, improve operating environment and control grinding ball quality.

2. Solved problems: On the basis of grinding ball production mechanization, automatic and intelligent technical upgrading is carried out. The main technical problems of the production line include: 

  •  In respect of the connection between single machine structure design and tie line, design and improve the safety of production control by virtue of systemic simulation technology.

  • solve the problems of poor operating environment, low production efficiency, high energy consumption, and quality instability, etc. 

 3. Function: 

  • The output of the single machine, single production line, and a single shift is about as high as 5000 ton/ year.

  • The technological yield of grinding ball is about 76%.

 4. Key technological and innovating points:

  • Double-station integrating sand-shooting technology is used to ensure the casting system and integrating the forming of product sand shooting.

  • The resonance cleaning mechanism is applied to achieve a high shake-out effect.

  • Automatic and intelligent mold temperature control is implemented, in accordance with technological mold pre-heating requirements different specifications of grinding balls.

  • Automatic and intelligent vertical insulating casting system technology is applied.

  • Integrated technology is applied to achieve automatic cleaning by metal mold assembling blowing and sending the used sand.

 Main characteristics of XN-TF-90II (Horizontal Parting) High Chrome mill ball casting production line 

1. It is applicable to the production of 40mm-150mm chromium forging ball and austempering ball product with the average machine-hour production capacity of about 2 tons/h.

2. Applied with ductile and open operational technology and principle, it has higher automaticity. There are four working stations in total and requiring five workers in a production line. 

3. Casting method:casting with bottom constant-temperature casting machine or multi-point casting ladle.

4. The equipment possesses over ten patents, which mainly embodies in:
Double-station core shooter
Integrated riser molding
Automatic sand shakeout
Automatic purging and intelligent temperature control design (sand shooting mold temperature control of mold condensate case unpacker) and other patents and technological innovations.

5. The overall production line can be equipped with dust-collecting and smoke-extracting environmental protection devices to satisfy the working environment for modern enterprises.
