How Raymond mill power computing

Since the particle size of the fine ore particles become mechanical strength is increased, it becomes difficult raymond mill, and ultrafine Raymond process under control poor, low energy conversion efficiency, so fine grinding and ultrafine grinding lower power consumption increases rapidly. At present, industrial enterprises need to be resolved under the fine grinding and ultrafine Raymond power of computational problems. The following three-pronged approach to calculate the power consumption of ultrafine Raymond. A known standard ore work index, can be measured by grinding the ore test work index determination Under the same conditions, with the same ground Raymond were the same weight of standard test ore and minerals, to find out from the sieve analysis curve them to the mine and the product. Raymond used the same ground under the same conditions the same quality of the ore consumed two functions should be equal. Second, the doctrine of presumed power by the area under different crushing ratio Raymond in the same models, with the prolonged grinding, crushing ratio increases, the power consumption increases. With the in-depth study of the power law, the existing power doctrine can also find new uses. Third, computing power Raymond Several power school, only Bond's original power formula is used to directly calculate the grinding power, because the power consumption of the original Bond formula, feed particle size and particle size sieve analysis can be measured, and Bond work index, can be measured Bond predetermined way, so Raymond grinding power required can be directly calculated. If you want to reduce the cost of Raymond, only to solve the above three problems consume work, it can greatly reduce the mechanical consumption and wear, thereby reducing the cost of production fundamentally.
