Ore milling equipment medium demand on gradation in the first silo from Richard Mrax's blog

As is known to us all, the main function of the first silo in ore milling equipment is to impact materials, which is also the most critical step of the whole ore milling equipment process. It affects not only the ore milling equipment effect but also that of other silos. Experts in ore milling equipment point out that silo is determined by the size and mean diameter of steel balls as well as technical parameters. The parameters are decided by product fineness and, more importantly, by the property and grind ability of materials. Accordingly, whether steel ball gradation is proper or not hinges on material demand. In the process of the first silo impacting, the following points needs taking into consideration: 1. The steel balls of the first silo should have enough impact capability, which surpasses the extreme of material hardness. 2. Sufficient impact times should be kept. The load has a lot to do with the diameter of steel balls. Therefore, in the case of ample impact frequency, the diameter of steel balls can be reduced and steel balls added. Thus, the ore milling equipment efficiency can be enhanced. 3. The ore milling equipment should have due material storing ability. To ensure that materials are well ground, materials should stay for a while in the silo. Consequently, the flow velocity should be regulated to avoid material jumping phenomenon. The experts with SBM Mining Machinery summarize the gradation methods with extensive experience and expertise. Every method has some merits and demerits, however. SBM will strive towards better solutions as always.
