63· It mainly includes crushing process control, crushing appliance fault diagnosis, and automatic distributing control. Crushing Process Control To ensure the continuous, stable, and safe operation of the ore crushing production process, it is necessary to monitor the running state and parameters of key equipment (such as crusher and belt conveyor) in real time for …
514· Primary wet screening was selected to remove the fines which caused plugging of the secondary and tertiary crushers and blinding of the tertiary screens in 1972.
The jaw crusher product would then be split down by the same ratio, so as to maintain the correct ratios. The usual area of failure of primary samplers is over-coarse feed, but this one would measure the coarse fraction at the same time, thus resolving this issue. A more traditional approach is to use a sampling tower for lump (30 x 6 mm) iron ore.

Prior to passing into the grinding circuit, crushing of the ore is initially performed using primary crusher followed by secondary crusher. Subsequently, the output is directed to the next unit, namely rod mill as a feed together with water.
The Primary Crusher discharges into a Primary Crusher Product Pocket from which crushed ore is withdrawn under gravity into four parallel Secondary Crushers (36” gyratory) that operate in a choke fed mode. A conveyor train (1A/2A), is fed by …
A good examples of this condition, and hence where power-based equations would be applicable, are illustrated in Figures 1 and 2 which show a primary …
The ore from the primary crusher is conveyed to secondary crushers, such as cone crushers or impact crushers. This stage further reduces the size of the ore into smaller, more uniform pieces, usually less than 2 inches.

Used as the primary comminution unit in a grinding circuit. Rods are placed parallel along the length of the rod mill. Rods are 150mm shorter than the mill length. Breakage occurs more from cascading than cateracting. The product size distribution is narrower than a ball mill but significantly coarser. Most are overflow discharge type. Length-to-diameter= 1.4 to 2.3. Mill …
