To provide smooth increase of starting current and the motor shaft torque, starting resistors are used. "PPTG", Ltd. develops and manufactures liquid and oil starting resistorsessential in severe applications, which are noted for low cost of service and high operational reliability.
The motor drives a cement ball mill, and the operator is blaming the starter but I think that if it is not accelerating as it used to then the load has increased. Any thoughts? Also the starter used soda ash (sodium carbonate) to modify the conductivity fo the water, does any one know what the chemistry of the liquid should be?

Ball mill is typically used to grind and/or blend materials and it can be done wet or dry. It can be used to mix ceramic powders, disperse particles in solvents, homogenize ceramic slurries, etc. Ball mills operate by rotating plastic jars around a horizontal axis, partially filled with the material to be ground plus the grinding medium.

The use of VSDs makes it very easy to set the mill speed by just modifying this value on a touchscreen. But this is not only an option for new installations. In installations where SAG and Ball mills have been working for several years at fixed speed, but the speed regulation has been observed to be necessary VSDs can also be integrated very ...
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 starting point for ball mill media and liquid charging is generally 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 45% to 50% above the ball charge for total of 58% ...
A ball mill is a grinder which is used to grind, blend and mix materials like chemicals, ores, pyrotechnics, paints, mineral dressing process, paint and ceramic raw materials. Its working principle is impact and attrition. Ball milling have proved to be effective in increasing solid-state chemical reactivity and production of amorphous materials.

Liquid to liquid heat exchangers For high start duty applications it is often necessary to add a liquid to liquid type heat exchanger and circulation pump to a HLR starter. These require a cool water supply to also be available on site and can be of the shell and tube or plate type depending upon site conditions and space limitations.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
