On-line mill charge detection methods have been developed with two primary approaches, imbedding strain gauges and integrated circuitry with grinding steel balls [], and imbedding sensors on the mill shell/liner [,,, ].The former approach records the movements of the mill charge both in the rotating and the longitude directions of the mill.

One way to prevent cement from ending up in landfills after its shelf life is to regain its activity and reuse it as a binder. As has been discovered, milling by planetary ball mill is not effective. Grinding by collision is considered a more efficient way to refine brittle material and, in the case of cement, to regain its activity. There has been considerable research regarding the …

A strain gauge sensor that measure the deflection of a lifter bar when it hits the charge inside a tumbling mill is studied for different operating conditions in a pilot scale ball mill. The deflection of the lifter bar during every mill revolution gives rise to a characteristic signal profile that is shown to

To improve the process control in a method and a corresponding device for regulating the rotational speed of agitator ball mills which have a grinding chamber with grinding balls contained therein, a rotatably mounted agitator body arranged in the grinding chamber and a drive for the agitator body, the rotational speed n of the agitator body being measured, the torque M …

Highlights We compare strain gauge measurements and calculated stresses for a large ball mill. Measured stresses are lower than calculated stresses at the inboard plate flange. Liner stiffness is the cause of the lower-than-expected measured stresses. We show that mills can be assessed using FEA and modern fatigue design codes. We show that the plate thickness effect is …

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

A deflection profile is registered and the signal pattern is correlated to charge position and filling level. Charge measurements in industrial-scale mills - a ball mill at the LKAB iron ore beneficiation plant in Malmberget and an AG-mill at the Boliden Aitik copper mine plant - as well as a comparison with a pilot scale ball mill are presented.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...

As the ball mill rotates, the steel balls in the cylinder rise up one end of the inside surface of the mill and eventually tumble down to the bottom. The raw material is fed into the ball mill at the ends, and the steel balls impacting together eventually grind the material into a powder which is collected through slots at the center of the mill.

This strain can be measured by a strain transducer.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball …

The MKM-System is an on-line measuring unit used to detect abnormalities during kiln operation which can lead to mechanical failures on any rotary kiln system (with more than 2 Stations). The main objective is to detect such abnormalities (thermal or permanent kiln cranks, lack of tire play) at an early stage.

The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

The standard sub-sampling box is a modified Marchant design consisting of an approximately 27 x 27 x 15 cm box that is divided into 100 cells and has a water tight lid. Wash the sample from the sieve into the Marchant Box and fill with water to a depth just below the height of the walls dividing the cells.
