There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time. Different alloys are recommended depending on ore type and mill particulars in order to arrive at the most cost economic solution. Based on our world wide experience, AIAE can help select optimum alloy for specific application ranging from Chromium 10 to 32 % and Hardness ranging from 58 to 69 RC.

The Group Industries has developed a whole series of alloys specifically suited to the different impact and abrasion conditions that can occur, such as low abrasionhigh impact and high abrasionlow impact. The overall specifications of the The Group Industries grinding media are shown in the table below. Changing impact conditions can cause conventional grinding media to either work harden or cause spalling – thus shortening working life, increasing downtime and increasing costs.

n addition to simplified installation procedures, the facility to choose different grades and specifications improves reliability and extends the working life of the unit. Customers can specify international standards for alloys or opt for the higher standards of The Group Industries alloys. These latter castings are designed and supplied with guarantees for working life and separation efficiency characteristics.

• AdvantagesOptimum expansion of the ball charge. ,Optimum lifting action of the balls. ,Minimize the dead zone of the ball charge. etc.

Based on study of the existing mill operating conditions from maintenance and process point of view, AIAE designs mining liners for ball mills of different stage. i.e. single stage, primary, secondary, regrind etc.

Whether using cone crushers, hammer crushers, impellor crushers or vertical shaft impact crushers; The Group can supply wear parts that offer significant cost benefits when compared to conventionally formulated and manufactured components. This has been achieved through the use of alloys and techniques that can produce higher tensile, higher stiffness and extended fatigue strength characteristics – in fact increasing the fatigue strength by a factor of 2 or even more is not uncommon.
