The best selling product of Henan Qianjin Heavy Industry in 2022 -- hollow shaft of ball mill

Technology is introduced

Hollow shaft is an important part of ball mill barrel rotation, which mainly plays a role of supporting and connecting the barrel in the whole machine, and is the inlet and outlet of materials, and the shaft diameter is mainly subjected to bending force when working.

The rounded corner at the end of hollow shaft of ball mill is the place of stress concentration, which is prone to sand holes, pores and microcracks during casting.

Processing advantages

1, hardness is 30% higher than peers

Adopting professional heat treatment technology, the hardness of hollow shaft is improved and the impact resistance is enhanced.

2, the service life is far more than the peer 50%

It is made of high-strength steel. In the early stage of casting, professional engineers optimize the process structure of the hollow shaft according to the operation characteristics of the ball mill, which largely guarantees the stability of the hollow shaft under long operation and prolongates the service life of the hollow shaft.

3. Short production cycle

Qianjin cast steel itself is a large steel casting processing base, which can produce hollow shaft and other parts in large quantities, with short casting cycle and large output
