Nowadays, energy-saving and commission reduction is an important policy in social tendency. For the mining process, the grinding stage is the most energy consumption one, so reducing energy consumption in the grinding stage is crucial to the mining process energy-saving work. Energy-saving Rod mill has been redesigned and developed in pre-fine-grinding for cement, which could inspire us in the use of rod milling machines in the mining process.
Pre-fine-grinding could reduce the particle size of the material before sending it to the grinding machine and prolong the grinding time and reduce the surface area of the material, which will increase the grinding quality. In order to meet the new cement standard, a particle size of cement should be appropriate. Some reformation of rod mill as follows:
(1) Fine grinding system assisting of rod mill and ball mill.
(2) Grinding medium changed from rod to rod and steel ball. Simplifying the process and reducing energy consumption.
(3) Changing ball mill system: removing centrifugal separation machine and change ball mill inside structure and process index, high-efficiency separation machine is used in the process line.
Xinhai has its own mine site research institute, rod rolling machine design institute, and mining process research institute to optimize mining process machines to meet the standard of energy-saving and commission reduction.
