Grate Ball Mill for Mineral Processing
Large mill/Grinding Mill:
Mills are widely used in industries such as metal beneficiation plant, metallurgy, chemistry, building material, thermal power plant. Etc. They are applied to pulverize all kinds of mineral and rock. Normally they are classified as over-flow ball mill, grate ball mill, rod mill, raw mill, cement mill. Etc.
We have large mill manufacturing equipments of the best quality and the excellent techniques. With our completed technical detection and service system, we have developed the full series of different types of mill products.
The supporting form of mill:
The supporting forms of mills are classified as double main bearing, double slipper bearing and single slipper bearing. Small and medium tube mills usually apply the supporting form of main bearing ; large mill usually applies the double slipper bearing supporting or main bearing supporting at one end and slipper bearing at the other end. All these three forms are equipped with high-low voltage lubrication station. As to the large raw mill and cement mill, we applied the double-slipper bearing supporting structure, which shortens the mill span distance, making its excellent loading and stable supporting. And also the cylindrical barrel thickness is reduced, which saves the cost and easy to built and maintained. With respects to large drying coal mill, we apply the single slipper bearing supporting structure at the feed end to expand the hot-blast air entering section surface into the drying cabin, thus reduce the air resistance inside the mill.
Drive type of the mill:
According to the mill specification and requirements of processing set-up, there are single-pinion driving, centre driving, and double-driving on each side and so on.
Control and protection system:
The whole mill system is controlled by PLC, which realizes the routing inspection of the mill supporting unit and all bearing lubrication of the reducer, and the inspection of the machine body vibration, and also realizes the computer combined control with the control room.

Application and Description of Ball Mill:
A ball mill is a type of grinder used to grind or mix materials like ores, chemicals, ceramic raw materials and paints.etc, into extremely fine powder for use in mineral dressing processes, pyrotechnics, ceramics and paints.
Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other end. Large or medium-sized ball mills are mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts (pulleys and belts are used to transmit rotary motion). A rock tumbler functions on the same principle. Ball mills are also used in pyrotechnics and the manufacture of black powder, but cannot be used in the preparation of some pyrotechnic mixtures such as flash powder because of their sensitivity to impact. High-quality ball mills are potentially expensive and can grind mixture particles to as small as 5 nm, enormously increasing surface area and reaction rates. The grinding works on the principle of critical speed. The critical speed can be understood as that speed after which the steel balls (which are responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding.
Ball mills are used extensively in the Mechanical alloying process[1] in which they are not only used for grinding but for cold welding as well, with the purpose of producing alloys from powders.
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material.
