The application of ball mill notions of mineral processing equipment
During a lot of mineral processing a ball mill is indispensable equipment in the ore dressing operation and this holds a position in the market. A ball mill is for all kinds of ores and other materials that may be either dry or wet grinding. It is widely used in cement, Portland products, new building material, refractory material, fertilizer, ferrous and non-ferrous metal ore dressing and glass ceramics production industry, etc.
In order to separate the gangue minerals in the ore to make various useful minerals separated from each other, you must first to assume a variety of mineral separation monomer. Mineral separation of monomer with only a broken method is difficult to achieve because the minerals are not uniform. Particle size of both a few millimeters mineral grains and a few microns particles are present. So, in order to make the mineral to monomer separation using the method of grinding doesn¡¯t work to the desired granularity in the best way. The grinding operation of the concentrator is the key in production operation.
The ball mill works because the ball is squeezed in the middle of the cylinder with the adjacent steel ball, so the couple can make the size of the friction force between steel balls. The steel ball, with the axis of cylinder for orbital motion, sets in the last fall area of cylinder body of the ore and produces a strong impact, crushing the ore. That is to say, the ore is mainly in ball mill cylinder body by grinding peel force, impact with the effect of extrusion and the ground. Ball mill works on the material from the feeder (hollow shaft into the cylinder body, when the ball mill cylinder rotates, grinding medium because of the inertia and centrifugal force. The effect of friction makes its post attached to the cylinder liner and it is taken away by cylinder. When it is brought to a certain height, due to the gravity of itself, it is dropped down and the whereabouts of the grinding medium is like a projectile of the cylinder body that causes the material to break.
Then, material composed of feeding device through the hollow shaft, spirals evenly into the ball mill which is the first warehouse. The warehouse has a ladder plate or corrugated plate. Built in are all kinds of steel balls, with a cylinder rotate falling after the ball to a certain height. The centrifugal force is generated on the material with grinding effect. Material in the first warehouse, after reaching coarse grinding, by the monolayer partition storehouse then board into the second warehouse with a flat plate, inside the steel ball, that will further grind the material. Powder through the unloading Bi board, finishes the grinding homework.
