The development of Loesche vertical roller mills for large capacity grinding is discussed. With 3+3 technology, the company is prepared to replace 2 to 3 ball mills in cement grinding plants with
It gives also a rough interpretation of the ball charge efficiency: Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):
Calculate Top Ball Size of Grinding Media Equation & MethodBall Mill Charge Metallurgist & Mineral Processing Engineer
Also with low ball charge slurry pool will reduce grinding efficiency. Beside lower ball charge will increase P80 of ball mill because
We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be

The ball mill is equipped with a classifying lining with a conical undulated shape. The absolute lifting height is quite similar to an industrial used liner plate. The discharge diaphragm is of the slotted type. The ball charge grading used during most of the test runs was an industrial standard grading with balls between 12 and 20 mm.
During the last decade, semifinishgrinding plants have been used more and more for the energy efficient grinding of highquality cement. In 1999, it was found that by decreasing the ball charge filling ratio it was possible to lower the specific energy demand for grinding significantly.
Abstract and Figures. The combination of a grinding circuit simulator with a model of ball wear in a grinding mill leads to a method to calculate, with a preselected accuracy, the makeup ball
Our PERI AutoCharge Mill Grinding Ball Charging System is designed to provide a controlled continuous supply of balls to maintain consistent ball loading in the grinding mill. Continuously charging grinding balls will allow your mill to maintain a consistent power draft, charge volume, ore feed rate, or consumption average (kg/t).
The second chamber is the fine grinding chamber. It is lined with classifyingtype mill shell liners and provided with finer ball charge. Classifying liners ensure that the ball charge is segregated along the length of the chamber keeping larger grinding media at the beginning of the compartment and smaller media towards the end of the
Key benefits. High reliability over a century of experience with 4000+ ball mills installed globally. Large throughflow area ensures low pressure drop across the mill. Horizontal slide shoe bearing design allows much simpler

Cement grinding operation may be performed in one of the following mill setups. Ball and tube mills. Vertical Roller Mills (VRM). Roller press with Ball mill. Ball Mill. Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 7080% of critical
was to locate the variation of ball filling in the mill. Ball Charge Program Abrasion In this section, ball abrasion was calculated via manufacture`s ball charge program. At the time of this research, mill ball charged, feed rate, and average moisture were 7 tons (ball size was 100 mm) per week, 720 t/h and 5%, respectively.
Costea et al. [13] developeda fuzzy logicbased control architecture in which the ball mill grinding process was considered as a single input and single output system (SISO) and the total feed
