filling in a laboratory ball mill would imply the maximum agitator shaft speed and 30min milling time. Keywords: fat filling, ball mill milling variables, physical properties, sensory characteristics, optimization. Fat fillings contain high amount of fat (30–40%) which presents a continuous phase and determines the consistency of the filling.
Ball Mill EnergySaving Principle Usually ball mill operates at fixed running speed, and the cylinder speed is determined by belt pulley and gear reduction mechanism (or hydraulic coupling). The rotating speed of ball mill directly affects the movement of steel balls and the grinding process of material.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50% of the mill volume and its size depends on the feed and mill size.

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
The process objective of the ball mill circuit control scheme is to maximise the grinding effort applied to solids delivered by the SAG mill. To prevent spillage and overload, the control scheme must allow the ball mill circuit to accept almost any amount of feed rate without overload.

The power ingesting of a grinding process is 5060% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.

These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a singlestage milling application to a semi autogenous ballmillcrushing circuit, and the application is well described. This refers to highaspect AG/SAG mills. Ball Charge Motion inside a SAG Mill
But many a neural network. When a new data comes we can real time systems, including the cement ball mill, either interpolate (inpaint) again and find the missing sample process variables nonuniformly. Hence, values or let the network predict and feed it back.
