  • Ball Mill Machine introduction


    Ball mill applies to grind all kinds of ores and other materials, widely used in mine-selection, building materials and chemical industry, etc. it can be divided into dry and wet two grinding ways. According to the different ways of discharging, it can be divided into grid type and overflow type.

    Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grindable materials.

     

    Ball Mill Machine Structure


    The machine is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbling process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition.
    Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.
     

     

    Working principle of Ball Mill Machine

     
    The Ball Grinder is horizontal cylindrical rotation device, driven by brim gearwheel. There are two chambers and grid. Material goes into the first chamber through the feeding inlet. Inside the first chamber, there are stage liners and ripple liners as well as steel balls. The shell rotates so as to generate electricity, and this force brings ball to a certain height and then balls drop down by gravity, the impact is the grinding force to the material. After the primary grinding, materials go into the second chamber through segregate screen. In the second chamber, there are flat liners and steel ball, after the secondary grinding, material is discharged from the discharging.
    Ball mill is an efficient machine for fine powder grinding and key equipment for grinding after the crushing process. There are two ways of ball mill grinding: the dry way and the wet way. It is used to grind many kinds of mineral ores and other materials, or to select mine. Ball mill is also widely used in the manufacturing industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other materials.

     

    Ball Mill Machine Features


    1. Rugged construction, reliable operation
    2 .Easy installation, adjustment and maintenance
    3. Large Capacity, continuous working

     

    Overview of Ball Mill Machine


    The ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the ball mill can grind various ores and other materials with dry type and wet type. There are two kinds of ball mill, grid type and overfall type due to different ways of discharging material.
