The effect of grate design on the behaviour of grate
01091986· A model for the effect of flowrate and viscosity of slurry on the holdup of slurry in a gratedischarge grinding mill has been developed. Given detailed specifications of the grate design (such as the area in the grate within which the holes are situated, the number of holes per m 2 and the hole size) and the flowrate and viscosity of the slurry flowing through the mill, the model provides
Converting a ball mill from overflow to grate discharge
The grate discharge arrangement removes this slurry pooling effect almost completely. Estimates of the increases in power draw possible with grate discharge ball mills range from 10% to 20%, according to mill size and other operating parameters. The figures from pilot tests and some operating sites are even higher, up to 25% more power draw.
Slurry flow in mills: grateonly discharge mechanism (Part
01072003· Discharge grates play an important role in determining the performance of autogenous, semiautogenous and grate discharge ball mills. The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate design––open area and position of apertures, as well as the performance of the pulp lifters.
