WhatsAppعرض المزيدA ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods. A tube mill is a revolving cylinder of up to five diameters in length used for fine pulverization of ore, rock, and other such materials; the material, mixed with water, is fed into the chamber from one end

WhatsAppعرض المزيدA ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical

WhatsAppعرض المزيدWe recommend a mixture of 1:2:3 for ball mill and rod mill foundations. The proper water to sand ratio should be carefully regulated since excess water increases the shrinkage in the concrete and lends to weaken it even more than a corresponding increase in the aggregate. Between 5½ to 8½ gallons of water to a sack of cement is usually recommended, the lower amount to be used where higher
WhatsAppعرض المزيدMost of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections. On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear driven rather than being driven by ring motors (gearless drives).
