Parameters of ball mill:
Ball mill is the material being broken in to smash the key equipment. It is widely used in cement, Portland products, new building material, refractory material, fertilizer, 52555 non-ferrous metal processing, convenient and ceramic lamp manufacturing industry of all kinds of ores and other materials may be grinding of dry or wet grinding. Ball mill is suitable for all kinds of ores and other materials, is widely used in mineral dressing, building materials and chemical and other industries, can be divided into dry type and wet type two kinds of grinding way. According to the row of ore in different ways, can be divided into grid type and overflow type two kinds.
Ball mill is a horizontal cylinder, in and out of the hollow shaft and grind the top of cylinder for a long cylinder, cylinder is equipped with the grinding body, cylinder for steel manufacturing, fixed with steel plate and cylinder, grinding medium, generally for the steel ball, and according to the different diameter and a certain proportion into the cylinder, the grinding medium steel section is also available.
With the particle size of grinding material selection, material since the hollow shaft ball mill feed end into the cylinder body, when the ball mill cylinder rotation, grinding medium because of inertia and centrifugal force effect, the effect of friction, making it attached to the cylinder liner was taken away by cylinder, when was brought to a certain height, be cast down by its own gravity, the whereabouts of the grinding medium like projectile of cylinder body of the material to break.
Material composed of feeding device through the hollow shaft spiral evenly into the mill the first storehouse, the cabin has a ladder plate or corrugated plate, built in all kinds of steel ball, cylinder rotate falling after the ball to a certain height, the centrifugal force is generated on the material and grinding effect. Material in the first warehouse after reaching coarse grinding, by monolayer partition storehouse board into the second warehouse, the warehouse with a flat plate, inside the steel ball, will further grinding material. Powder through the stripper plate, finish grinding homework.
Cylinder in the process of turning, grinding medium has slipped phenomenon, in the process of slide to the material to grinding effect, in order to effectively use of grinding, the material particle size and the larger general 20 grinding fine time, the mill cylinder body with every storehouse board separated into two parts, namely become two bin, material is steel ball break into the first warehouse, material into the second warehouse, steel section for material grinding, fine grinding qualified material from the discharge end of the hollow shaft discharge, material of feed particles small mill, such as sand ii slag, crude ash, mill cylinder body facility clapboard, into a single warehouse tube mill, grinding medium can also use the steel section.
Raw materials through the hollow shaft neck into the hollow cylinder grinding, the diameter of the cylinder is equipped with a variety of grinding medium (steel ball, steel rods or gravel, etc.). When the cylinder at a certain speed around the horizontal axis rotation, the cylinder is mounted on a medium and materials under the action of centrifugal force and friction, as the cylinder reaches a certain height, when their own gravity is greater than the centrifugal force, then falling mass ejection from the cylinder or roll, break ore due to the impact. At the same time, in the process of mill rotation, grinding medium between the sliding movement of raw materials and grinding effect. After grinding material through the hollow shaft neck.
