Fly Ash Ball Mill

The fly ash ball mill is an essential piece of equipment used for crushing and grinding materials. It is suitable for both dry and wet grinding of various ores and other materials, making it widely used in industries such as ore beneficiation, building materials, and chemical engineering.


    The fly ash ball mill consists of several parts, including the feeding, discharging, rotating, and transmission parts ( reducer, small driving gear, motor, and electrical control). The hollow shaft is made of cast steel and the lining can be replaced. The rotary gear is processed by casting hobbing, and the cylinder is lined with a wear-resistant liner that provides good wear resistance.

    The fly ash ball mill's main engine includes a cylinder lined with wear-resistant materials, bearings, and drive components such as motors, transmission gears, pulleys, and V-belts, ensuring smooth operation.

    Working Principle

    The material is fed into the cylinder of the ball mill through the feeding end, based on its size. As the cylinder starts rotating, the grinding media sticks to the lining plates near the cylinder. Due to the influence of inertia, centrifugal force, and friction, the grinding media reaches a certain height as the cylinder rotates. At this point, the grinding media falls and crushes the materials within the cylinder.

    Stable output and reliable product
    The fly ash ball mill is designed with a wide discharge opening to increase the speed of discharged materials and minimize the pulverization of fly ash, resulting in a more consistent particle size distribution.
    Compact structure with high operational performance
    The mill adopts a center single-drive transmission method, which makes its structure more compact, improves grinding efficiency, and enhances operational reliability.
    Effectively reduce energy consumption
    The grooved ring design liner effectively increases the surface area of contact between the ball and ash powder, which enhances the grinding effect of fly ash and reduces the energy consumption of the ball mill at the same time.
    Reduced noise and long gear life
    Fly ash ball mill adopts the a large modulus alloy steel cast gear design, which effectively reduces the operation noise of the equipment and prolongs the service life of the gears.
    Automatic control
    The fly ash ball mill utilizes PLC automation centralized control, making the operation and maintenance easier and more convenient.
    Small friction, low energy consumption
    The fly ash ball mill utilizes a new lubrication structure, which reduces oil consumption to only 75% of traditional ball mills. This effectively minimizes equipment operation friction.
