Ball Mill For Grinding Lime Mortar.Ball Mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes. It works on the principle of impact sie reduction is done by impact as the balls drop from near the top of the shell.
Our products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
Besides there is some other auxiliary equipment like Lab testing equipment waste sand recycling machine pouring ladle car for balls forming sand mixer balls selection machine etc. For lab testers such as the spectrometer Rockwell hardness tester falling ball test machine and microscope plays a vital role during the producing process.

Ball compression is a measure of a balls hardness. A standardied method has been developed to measure this property ASTM F1888. The test apparatus is depicted in Fig. 3.1. The test involves measuring the force to displace a ball 0.25 inches in 15 seconds between flat platens. The ball is compressed twice once along each ear axis.

The grinding balls surface hardness defines on two diametrically opposite platforms. Four measurements perform at each platform for the hardness determination by Rockwell method. The first three measurements perform at the vertices of imaginary equilateral triangle with a side length from 5 to 8 mm. These measurements are tentative and the results dont record in test report.
