How to Improve the Quality of Grinding Material

The grinding operation is useful minerals in the ore and gangue to monomer dissociation, and the smooth progress of the selection, the most important prerequisite for higher beneficiation indicators. Good grinding quality should be grinding to give flotation to provide useful minerals and gangue in the ore can achieve up to monomer dissociation, without producing mill, stable grinding for flotation conditions concentrated fineness of grinding of minerals. There are many factors that affect the quality of ball mill grinding, Some factors affecting this: 
The main factors affecting the quality of the grinding: ore hardness and feed size, machine speed to the size and stability of the ore, the mill specification model, the number of balls, the size and proportions, ball mill liners, mill speed, grading, sub- level machine spindle lift height, leaf plates and blades in good condition, the level of the overflow weir, the opening level of the classifier, the size of openings in the level of the size of the ball mill to the mine water size, mill Pai mine mouth water size.
Milling work daily adjustable parameters need to focus on are: ball mill to the mine water (including the size of the anti-sand slot rinse water), add water the size of the ore mill Pai mine mouth to mine, and so on.
Ball mill (ball mill) to add water to the mine: the ball mill to the mine water increases, the shorter the residence time of ore in the mill, smaller grinding row of ore concentration, particle size coarsening; on the contrary, the ball mill to reduce the amount of water, or The residence time in the mill relative growth, the concentration of grinding larger, thinner granularity.
  Ball mill (ball mill) row of ore and water: The ball mill discharge mouth water content increases, anti-sand grading machines increases, so that the overflow concentration is smaller, thinner granularity; the contrary, the ball mill discharge mouth water content decreases, grader anti-sand decreases, so that the overflow concentration of larger particle size coarsening.
Ore factors: the stability of the ore directly affect the quality of grinding, but also affects the fineness of the classification overflow. To the small magnitude of the changes in the amount of ore, the grinding and classification operations to stabilize the quality of the product of grinding and classification is like, the smaller the change in amplitude, the more stable operation of grinding and classification, the better the quality of the product of grinding and classification. Otherwise, the deterioration in the quality of the product of grinding and classification.
