Because the ball mill pulverizing system is non-linearity, long time delay and time-varying, the reliable and effective method for measuring the fill level was lacked at present. In order to reduce the influence by various factors on measuring the fill level and improve the measuring accuracy of the fill level, a novel characteristic variable is proposed.

The exact measurement of the fill level is the key and basic problem for automatic control and optimized operation of the coal pulverizing system. Because the ball mill pulverizing system is non-linearity, long time delay and time-varying, the reliable and effective method for measuring the fill level was lacked at present. In order to reduce the influence by various factors on measuring the ...

2009-11-1 Zhang (2001) studied the fill level by measuring the energy consumption of the mill motor, but the wear of steel balls and the variation of ball load can seriously affect the power value of the mill. Kolacz (1997) proposed a method to measure the fill level by using a strain transducer. The transducer was installed at the middle of the mill shell.

The ball will sink until the density of the material in the ball and in the thickener is the same e.g. if the ball is set up to measure the mud, the ball would sink through the clear zone, through the interface and float on the mud. Once the ball has touched mud, this point will be recorded as the mud level.

2018-4-20 However, all these level transmitters measure the level in either of the three ways: The weight of the fluid. The pressure head of the fluid. The position of the fluid in a container. If you look closely, all the pressure transmitters covered in this post take into account either of the three factors to give an appropriate measurement.

2017-2-20 All Grinding Mill Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

2021-6-20 Abstract. Seepage surface position of fill slope can fluctuate owing to rainfall and groundwater supply from behind the slope. Therefore, in this study, shaking-table tests of an unsaturated fill slope were conducted to examine the influence of the seepage surface position on the fill slope stability by comparing with previous results in the fully saturated condition.

It is a function of particle size distribution and shape but is also influenced by friction and other variables. Flow determines the time required to fill a die and thus determines the production rate that can be achieved.
