Detailed Product Description
Name:high chrome cast grinding ball
They are widely to apply in cement building materials, power industry. During the process of production, under the conditions of single warehouse as well as normal mining: 40 grams are needed by per tonne of cement as national standard; 30 grams as our enterprise; according to the feedback of the patrons, that's only need 18-19grams.
