WhatsApp: +86 18037808511Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
WhatsApp: +86 18037808511The SAG grinding ball size is usually about 125mm. But more and more mining company adopt bigger size, like 135~150mm. ... if we choose the suitable grinding ball, the ball mill will work in high efficiency, meanwhile it will consume few gridning balls. ... it save a lot of operation cost for ore grinding. from long time experience of produce ...
WhatsApp: +86 18037808511Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
WhatsApp: +86 18037808511Gridtype ball mill: When a product with a fineness of and uniform fineness is required, it is better to use a gridtype ball mill. It can discharge qualified products in time, reduce the overgrinding of ore, and improve grinding efficiency. Gridtype ball mill is often used in the first stage grinding system.
WhatsApp: +86 18037808511Three "ores" were used in theBall Mill Grinding experiments. It is doubtful whether material more resistant to grinding can be found among the world's ores. When flotation was newer and regarded as the panacea in ore treatment, the TriState operators were critized for not grinding the entire mill feed to flotation size and thereby ...
