2020-04-26· C. Gear pump with adjustable speed motor for feeding of the mixture to the mill. D. Vertical ball mill, composed of a double walled grinding chamber, with thermostatic control also nocturnal, having internal lining, shaft, arms and grinding balls in special alloy with high resistance to mechanical abrasion.
2020-05-18· Ball Mill Motor Sizing Calculation Example. A 7 ft diameter dry grinding diaphragm mill has a 40 percent ball charge and a speed of 23.6 rpm. What is the horsepower per foot of length? The mill has 2 in. thick shell liners. From graph, Fig. 3, 12, mill having 6 ft 8 in. inside diameter will have 4400 lb of balls per ft of mill length.
The impressive speed of 2,000 min-1, so far unrivaled in a ball mill, in combination with the special grinding jar design generates a vast amount of size reduction energy. Thanks to the new liquid cooling system, excess thermal energy is quickly discharged preventing both sample and mill from overheating, even after long grinding times.
