A rod mill was fed from a cone crusher at the rate of 250 t/h with a copper ore. The product size from the cone crusher is 12,000 μm. The rod mill, operating wet and in open circuit, produced a product 80% passing size of 600 μm. The product was then pumped to a ball mill, which was operated wet in closed circuit.
In the cement production process, coal preparation is an important part. After the cement burning coal required, subject to crushing grinding, made to meet the requirements of burning pulverized coal particle size, respectively, to the kiln and kiln decomposing furnace, in order to fully burn, sufficient combustion reaction capability.
For a rod mill–ball mill circuit, do not apply a mill diameter correction for the ball mill. If the rod mill feed is produced by open circuit crushing, use a factor of 1.2 for the rod mill stage only. If the rod mill feed is 80% passing 12 mm or less e.g. from a closed circuit crusher do not apply a rod mill efficiency factor.
You can starting a charcoal briquette business with straw rod making machine. There is a demand for the size of the broken material. Before entering the straw rod making machine, it is necessary for the straw and other materials to enter the straw rod making machine after being crushed by the straw crusher.
