The greatest challenge when developing a high energy ball mill is keeping the temperature under control as the enormous size reduction energy leads to considerable heat built-up inside the grinding jar. RETSCH solved this problem with an innovative integrated water cooling system.
Feb 10, 2014 Casting steel ball are most used in ball mill in metallurgy, cement, water coal slurry, new construction material and magnetic materials fields. Temperature of ball mill has an important impact on the quality of products. To understand the issue of temperature control of ball mill can better finish grinding. Temperature of ball mill is big issue.
Ball Mill Cylinders. Mill cylinders are typically supplied with a cooling jacket on their cylindrical portion for temperature control, especially when processing temperature-sensitive materials. For extreme temperatures, the ends of the cylinder can also be furnished with cooling apparatus. View a Reverse Engineered Patterson Ball Mill Cylinder ...
Further, Attritor tanks are all jacketed which allows for more precise temperature control during high energy ball milling. The savings in energy and the increase in grinding efficiency provided by Attritors are substantial. The graph below compares various mills during the high energy ball milling process.
Metso Outotec has designed, manufactured and installed over 8,000 ball and pebble mills all over the world for a wide range of applications. Some of those applications are grate discharge, peripheral discharge, dry grinding, special length to diameter ratio, high temperature milling oprations and more.
Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills dry basis is typically 75 vol.- ore and 25 steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
Horizontal Ball Mill slakers measure temperature at the discharge so control has some lag. Paste slakers and Batch slakers usually monitor temperature but it is not the control variable. Paste slakers use torque either directly via a clutch or indirectly via amp draw measurement to control the consistency of the paste in the slaker.
