How to choose the right vertical sand mill & horizontal sand mill?
1. The temperature of the slurry at the pre -scattered stage is not high, but once the horizontal sand mill began, the temperature of the slurry in the grinding cavity exceeds the protection temperature, so that the sand mill was stopped. In the case, we can appropriately increase the speed of the feed pump, thereby shortening the stay of the …
