The choice between wet and dry milling is, in general, unimportant in smallscale milling but isajor technical problem when largescale milling in the metallurgical industries is involved. on purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling.
Wet mill is bothereal grain production process and the machinery used for wet milling. the wet milling process involves using water to break down grains prior to milling. this allows the individual parts of the grain to separate from one another for easier harvesting. the wet mill process isommon method of harvesting grain for food components, but dry milling is more.
Ball milling,hearforce dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls generally zirconia zro2 or steel balls, acting as grinding media and rotating shell to create centrifugal force.
There has beenell established truth that wet grinding is more efficient than dry grind ing. this should apply to ball mill grinding as well as autogenous grinding. it has been earlier shown that the effect of dry ball mill grinding increases considerably, when the fines are efficiently removed from the mill.
Wet milling of wheat is the process of separating flour into its components, primarily starch and gluten, using water in the process. this can easily be illustrated inousehold kitchen. take some flour and add enough water to formough ball and then knead the ball forew minutes to allow the gluten to form.
The terms wet milling and dry milling are overarching concepts that do little to actually describe the processes and forces involved. but some methods are only possible under wet conditions, and some require dry milling conditions. although the goal of both grinding methods is to reduce particle sizes toarget range, the processes are different.
The wetbulb globe temperature wbgt iseasure of the heat stress in direct sunlight, which takes into account temperature, humidity, wind speed, sun angle and cloud cover solar radiation. this differs from the heat index, which takes into consideration temperature and humidity and is calculated for shady areas.

Ball mills are the most commonly used piece of equipment for milling. however, vibratory mills, attrition mills, and fluid energy mills also are used. crushing and grinding typically are dry processes milling may beet or dry process. in wet milling, water or alcohol commonly is used as the milling liquid.

Wet milling, also known as wet grinding, isrocess through which particles that are suspended iniquid slurry are dispersed in that liquid by shearing or crushing. once the milling process is complete, these particles are ready for use or can be dried and separated for incorporation into additional products. wet milling is more complex.

Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparingide spectrum of powder materials and their alloys. in fact, ball milling process is not new and dates back to more than 150 years. it has been used in size comminutions of ore, mineral dressing, preparing talc.
A slight difference of condition between the two cases, however, is that with dry milling the fluid air fills the whole of the mill shell not occupied by the balls, whereas with wet milling the liquid occupies onlyart of the mill volume not occupied by the solid charge.
The ball mill system consists of one turn disc turn table and two or four bowls. the turn disc rotates in one direction while the bowls rotate in the opposite direction. the centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling.
