Heat treatment plant can be used to do the quenching (air, water and oil and the other quench media),and tempering for different alloyed castings, like casting grinding balls, Hi-Mn alloyed hammer, liners etc. The working process is fully automatic, one operator is enough.

Fig. 4 is the hardness contrast of grinding media under different heat treatment process. From Fig. 4, it can be seen that the hardness of grinding media is the highest after quenching at 980 °C, and the hardness reaches 65HRC.

Grinding Media for the mining industry is highly engineered product. Factors such as size, density, hardness and composition all play a role in the grade of grinding media manufactured. Grinding media/ball stock is made from round bar which is forged into grinding balls.

QUENCHING MEDIA. The cooling rate of an object depends on many things. The size, composition, and initial temperature of the part and final properties are the deciding factors in selecting the quenching medium.A quenching medium must cool the metal at a rate rapid enough to produce the desired results.

Middle casting grinding media balls and low chrome casting grinding media balls just tempering. High Chrome cast grinding media ball(Cr over 10%) need quenching first then tempering. CADI grinding balls need isothermal quenching,then tempering. Ningguo Zhicheng offer heat treatment furnace from capacity 3ton per day to 25 ton per days.

Its advanced program can improve productivity and save energy. And compared with car-bottom heat treatment (quenching) furnace, it can save electricity 35%-50% more. The effect of quenching is better and can stabilize; For example, in the oil quenching conditions, it can ensure the grinding ball and cylpebs' quench uniformly.

For producing qualified casting grinding media balls, quenching is the very important process. After molding by the molding line, the balls HRC is low, about 40-50 degrees. It is much lower than what we needed for balls. So we need to do quenching. Quenching for balls has oil quenching, air quenching.

Quenching is the process of rapidly cooling a material (usually a metal) in order to obtain desirable mechanical properties like increased strength and hardness. Most people think quenching is just dunking red-hot steel into a bucket of water, but materials scientists can quench in water, oil, liquid nitrogen, or even air.

during the quenching and equalizing stages depend. upon the size of the ball (Camurri et al., 2008). The aim of this work is to pr esent the results of. the computer simulation of the heat ...

Advanced heat treatment is certainly the best-kept secret to the excellent quality of grinding media of RESMINER. It is the final and most essential operation for preserving and enhancing grinding media quality. We have created world-class cooling equipment that uses oil quenching or non-oily water-soluble quenching techniques, among other things.

Grinding media represents l ow hanging fruit for most miners. Most often, the grinding media in question are grinding balls. In some mid-cap mines, grinding media makes up ~10% of total mining operational expenses (OPEX) and significant savings can be achieved.
