How to increase the temperature of the ball mill in the lab?

[tuyetanh]

I want to grind the clinker with grinding aids such as CBA, HEA2. However, these grinding aids act only with clinker above 60 celcius degree. The temperature of the ball mill in our lab is 38 celcius degree. Please tell me how to increase the temperature of our mill in the lab up to 60 celcius degree so that I can study the effect of these grinding aids. Thanks a lot.

Could you not install a thermostat controlled heater in your ball mill ?

Attach heating plates to the ends of the ball mill, then you can use a imple power supply.
