The determination of the specific energy depends among others on the mode of grinding operation. For a grinding process in a circulating mode (multi-passes), the specific energy can be determined as follows: (1) SE = ∫ 0 t N τ − N 0 d τ m P Where m P is the mass of the solid product, N(τ) is the power at the time τ and N 0 is the no-load …
Introduction. Calcite is one of the most abundant simple salts in the earth's surface and in sedimentary rocks; it occurs in the form of armours and skeletal frames of marine creatures. It is the prime constituent of limestone, chalk etc. In igneous rocks, calcites are present in the form of fine-to-coarse grains.

Accordingly, the grinding optimization method can be proposed, that is, after the sequencing of tin grinding for 4 Min, another 4 min grinding is conducted to sort the sulfide ore. This process can alleviate the conflict of cassiterite overgrinding and sulfide ore undergrinding, and the grinding energy can also be utilized most efficiently.
