The SAG mill is followed by two 20ft diam., 7,500hp geardriven ball mills. Another type of drive, less commonly used, consists of a motordriven speed reducer that is coupled to one of two ...Chat Online
Experience of manufacturing and installing over 2000 ore processing project globally and enjoys a high reputation in more than 160 countries and regions in the world.
The point where the mill becomes a centrifuge is called the quotcritical speedquot, and ball mills usually operate at 65 to 75 of the critical speed. application ball mill is the key equipment for grinding after the crushing process, and it is widely used in the manufacture industries, such as cement, silicate, new building material, refractory ...
The mill was loaded with 26.3 kg of 5mm steel balls, corresponding to 60 of the mill volume filled by a ball bed. a steadystate condition was established by feeding the sand at a given feed rate until the solid discharge rate attained the same value as the feed rate and the size distribution of the product did not change with time.
Cylindrical ball mills. the only cylindrical ball mills in common use are those of the grate discharge type, the most important being the marcy and the allischalmers mills. fig. 10 illustrates the construction of the marcy ball mill. the cylindrical shell and the feed and discharge heads are made of cast semisteel.
The machine is composed by feeding part, discharging part, rotation part and driving part reducer, small driving gear, electric motor and electric control. features 1. easy maintenance and operation 2. big crushing ratio, uniform end product size 3. simple structure 4. low operating cost. pictures show
Worldwide we have designed and built more than 1,000 tube mills. our driving force. the standard khd humboldt wedag mill is shellsupported on slide shoes and has a central drive. torque transmission is effected via the conical discharge end. this cone is welded to the mill shell and has openings for the discharge of material and exhaust gases.
Ball mill working principle center drive and side drive are two common drive modes for a ball mill. center drive grinding mill means the motor shaft extends along the axis of mill body while side drive has a motor located on the side of the mill and torque is transmitted via the girth gear which is bolted on the flange of the mill body.
Ball mill working principlemain parts of ball mill include feeding part, main bearing, rotating part, driving part big and small gear device, air clutch, main motor, slow driving device, jacking device, lubrication system and electric control system.
