flexlink calculation tool is another free conveyor belt design software for windows.using this free software, you can design different kinds of conveyor belts. creating or editing more than one conveyor belt design simultaneously is also possible as it opens each new project in a separate tab.
the calculation results can however differ from our calculation programme b_rex (free download on the internet under www.siegling.com). these differences are a result of the basically different approaches: whereas b_rex is based on empirical measurements and requires a detailed description of the machine, the calculation methods here are
1 calculation of ball mill capacity. the production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. there are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of
