Hot rolling grinding ball production line

The rolling grinding ball production line has the following characteristics through multiple innovative designs:

1. Automatic feeding control, improved automation level, and reduced labor intensity for workers;

2. Adopting induction heating, environmentally friendly and pollution-free, uniform temperature, and high production efficiency;

3. The ball rolling machine adopts a cast steel semi closed frame, with good rigidity and no deformation of the base;

4. The rolling mill is equipped with an electric side pressure adjustment device, which is easy to adjust and operate.

5. Automatic control of quenching and tempering temperature for steel ball heat treatment to ensure quenching and tempering quality;

6. The produced steel balls have exquisite appearance, high hardness, and low damage rate.

The grinding steel balls produced by our company's steel ball rolling equipment have precise dimensions, round geometric shapes, high hardness, and good mechanical properties, as well as excellent qualities such as wear resistance, no deformation, and no cracking. Its characteristics are manifested as:

a、 Overall high hardness: surface hardness can reach 57HRC-67HRC, volume hardness can reach 56HRC-64HRC, and the hardness gradient distribution is uniform;

b、 High impact toughness: impact toughness greater than 12J/cm;

c、 Low damage rate: The anti stripping and anti crushing performance is more than 10 times that of general cast steel balls, with over 20000 impacts from falling balls. The actual damage rate does not exceed 1%, which is close to no breakage.

Main technical parameters of grinding steel ball rolling mill:

After thorough research by our company's engineering and technical personnel on the steel ball rolling production line, combined with the domestic and international steel ball market demand, we have developed and manufactured a new generation of steel ball rolling production line. We have also developed a series of automated complete sets of equipment for heating, rolling, and heat treatment, which are used to produce various specifications of steel balls with diameters ranging from 20mm to 125mm.

Main production process of hot-rolled ball mill steel ball production line (offline tempering)

1. After inspection, round steel bars are cut into steel ball blanks (usually 5000mm-6000mm) according to a fixed length.

2. The steel ball billet is heated to a suitable temperature in an induction heating furnace before rolling.

3. After being fed into the steel ball rolling mill, the red hot steel billet rotates and advances between two rolls with special spiral hole patterns, and is continuously rolled into steel balls. Each steel ball rolling mill can produce 30-200 steel balls per minute.   

4. When the red hot steel balls are cooled to the quenching temperature after rolling, they immediately enter the drum quenching machine for quenching. The steel balls are collected and cooled in a collection box, and tempered in an offline trolley type resistance furnace to obtain high and uniform hardness.

5. The products that have passed the inspection are sent to the finished product warehouse, packaged, and then sent to the customer.

1. Technical after-sales service with professional engineers for overseas equipment.

2. On site technical service guidance and training for operators to proficiently operate the entire equipment.

3. The warranty period is 12 months and online permanent service is provided.
