Production Methods for Different Diameters of Grinding Steel Ball

Production methods:
1) For miniature steel balls or small quantity- processing in small cycle
2) For precision balls with large quantity- processing in big cycle
3) For precision balls in fisrt lapping and second lapping with small quantity- processing on panel with muti grooves
4) For large steel balls- processing on panel with one groove
5) For steel balls with diameter over 200mm- processing one by one

Involved processes:
1) Diameter betwween 28mm to 50mm
Heating- Hot Heading/ Hot Rolling- Annealing- Flashing- Heattreatment- Grinding- Find Grinding- First Lapping- Second Lapping
2) Grinding Steel BallDiameter betwween 50mm to 80mm
Heating- Hot Cutting- Heating- Hot Heading-Annealing- Refining Surface- Flashing- Heattreatment- Grinding- Find Grinding- First Lapping- Second Lapping
3) Grinding Steel Ball Diameter over 80mm grinding ball
Heating- Hot Heading/Forging- Annealing- Refining Surface- Soft Grinding- Heattreatment- Grinding- Find Grinding

The characters of the forging production

(1) Forging can change internal organization of metal materials, granular crystal, improve its mechanical properties.

(2) Forging production must use many auxiliary heating equipment, forging equipment and other tools.

(3) Forging equipments mainly include: steam hammer, air hammer, forging hammer, machine hammer, jump hammer, spring hammer, belt drop-ham

Grinding steel ball processing technology

Grinding steel ball processing technology should meet the standard requirements of the product, make grinding steel ball has high service life, low noise, low friction and high reliability. Generally has the following several kinds of basic processing methods:

1) the pulmonary circulation processing technology for small grinding steel ball processing and production.

2) big circulation processing technology used in large batch, high precision of grinding steel ball production.

3) single disc groove machining process used in small batch, high precision after quenching grinding steel ball grinding and lapping.

4) single disc groove processing used in the production of larger diameter of grinding steel ball.

5) a single grinding steel ball processing technology for oversize grinding steel ball (diameter phi 200 mm) above the production.

Goldpro is one manufacturer & exporter of grinding media steel balls in China. supply different sizes of grinding steel balls, forged steel balls according to ore conditions for customers.

Grinding steel ball test goldpro

Industrial test of two different grades of grinding ball can be done either by dumping the factory and loaded with a new initial charge, or by completing the new quality on the old charge until the initial load is completely moved. Of course , the timing of different test and costs are associated with each solution. Before the test the behavior of the new load data can be accepted as representing the time required to completely displace the old charge ( washout period ) is when the new tax will reach equilibrium, must be determined.

In order to calculate the time required for each test solution , the right to use grinding media must be considered.

Over the years , there have been many investigations to determine the appropriate mathematical formula, or the right to wear, which accurately describes the wear behavior of grinding elements in rotary mills . For the law of wear basic equation can be viewed at the following:

W = weight of the grinding ball [g]

T = time [s]

K = constant proportional

D = grinding ball diameter [ mm ]

n = wear rate
