effect of grate discharge area of sag mill grinding england series. descriprion:Once the slurry has made its way via the grinding media charge, its first stage of discharge is via the grate hence, in the absence of any subsequent restriction, the maximum flow capacity that can be obtained for a given mill is determined by the grate design here, the design variables are the …
The discharge grates of the SAG mill were identified as a key component in the SABC circuit, and their design is a crucial factor in the mill's performance [17,18,19,20,21]. The initial design of the grate section caused a serious accumulation of pebbles within the SAG mill which contributed to a decreased grinding efficiency.
