The basic principle of limestone Ball Mill grinding operations

Limestone ball mill is one of the important equipment in mining, metallurgy, chemical industry production. Master the basic theory of limestone ball mill grinding process, and explore its law of grinding operations , to identify factors that affect the productivity of the limestone ball mill, to improve limestone ball mill work efficiency has an important significance.

Limestone ball mill grinding process
Most grinding operations within many equipped with were cylindrical grinding media, due to the continuous rotation of the cylinder and the grinding media brought to a certain height, and then fall by its own weight, thus creating the desired impact crushed material . Meanwhile, due to the grinding media in the barrel along the cylinder axis for the revolution and rotation, so that the grinding media in contact with the cylinder interval between squeezing and grinding forces generated, so that the ore milled.
Grinding operations, who add water called wet grinding, no water is called the dry grinding. Grinding operations use more hardness and a large proportion of forged (or cast) manufactured balls and long sticks, while softer ground ore, sometimes using gravel.

The basic principle of Limestone ball mill grinding operations
Ball in a limestone ball mill operation, the main cylinder rotation speed depending on the speed may be, at low speeds, the ball was taken to a small height, weight and then by the natural angle of repose of the horizontal grinding decline in the role this time is the ball movement the sum of the impact and grinding stripping force generated when a limestone ball mill of this work system called diarrhea fall.

Increasing the rotational speed of the limestone ball mill, the ball under the action of centrifugal force, the lifted height increases, to a certain height to leave the tube wall along a parabolic orbit after the fall, because the ball has a certain height of drop in the level of the initial velocity, so have some momentum and impact, the ball continues to move, this grinding system called Paola type . Mill operation is basically in accordance with the truth.

Further increase the speed of the limestone ball mill, when a certain speed limit is reached, the ball is rotated together with the barrel under the centrifugal force, without departing from the cylinder wall, which do not occur in the grinding action, the operation is called a centrifugal limestone ball mill,
