Ball Mill Working Principle:
Ball mill is the key equipment of further Crushing after the materials being crushed. It is widely used in cement, silicate products new building materials, chemical fertilizer, Non-ferrous metal processing, glass-ceramic, etc.
All kinds of ores and other materials may be grinded by the way of dry or wet grinding. Ball mill is suitable for grinding all kinds of ores and other materials, and is widely used in mineral processing, building materials and chemical and other industries. It can be divided into dry and wet type grinding ways according to the row of ore different ways, which can divide the grate type and the overflow ones. According to the row of ore different ways, can divide the grate type and the overflow type two kinds. It can be divided into short tube mill, their ball mill, tube mill and cone type according to the barrel shape.
Ball mill is made of horizontal barrel, access to material hollow shaft and grinding pads. The mainbody of the ball mill is a low-speed rotary cylinder mounted on two large bearings horizontally. The ball mill rotary part is driven at reducing speed by motor through speed reducer and gearweheel or by low-speed synchronous motor through gearwheel. Inside the cylinder feed proper grinding medium-steel balls. The medium will be lifted to certain height under the action of centrifugal force and friction and drop or fall.
The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
