transcript: crushing, grinding, and polishing machine workers operate the equipment used to process materials such as coal, glass, grain, and rubber. these machine operators review work orders and load specified amounts of materials or mixtures into machines. workers sometimes break materials down to size using picks or other hand tools, to ensure equipment operates safely and the process usually, grinding only takes a few minutes so that the sample does not get warm during the process. if, however, longer grinding times are required, it is also possible to pre-select periods of intermediate cooling and the number of cryogenic cycles. all instrument parameters are retained during standby operation for subsequent processes.
