WhatsApp: +86 18838072829Introduction. The ball mill is the key equipment for grinding the minerals after the ore is crushed. With the continuous development of the industrial level, the development of ball mills is also moving towards the trend of largescale 1 to the large shock force generated during the operation of the large ball mill, the foundation of the ball mill will vibrate 5, 6.
WhatsApp: +86 18838072829Type of ball mill: • There is no fundamental restriction to the type of ball mill used for organic synthesis (planetary ball mill, mixer ball mill, vibration ball mill, .). • The scale of reaction determines the size and the type of ball mill. • Vessels for laboratory vibration ball mills are normally restricted to a volume of 50 cm3.
WhatsApp: +86 18838072829For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied.
WhatsApp: +86 1883807282912. If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is increases. During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 ton/hr of powder and energy requirement of the ball mill is about 16 kwh/ton.
