Investigation on measuring the fill level of an industrial ball mill
Zhang (2001) studied the fill level by measuring the energy consumption of the mill motor, but the wear of steel balls and the variation of ball load can seriously affect the power value of the mill. Kolacz (1997) proposed a method to measure the fill level by using a strain transducer. The transducer was installed at the middle of the mill shell.in the coal mills. While appropriate precautions differ at the various stages of the process, this article concentrates on appropriate detection methods for coal mills. Each generating unit at Merom has three Riley Power double-ended ball tube mills. The mills can each provide 65 tph of pulverised coal to the boiler, a total of 195 tph per boiler.COAL MILL Land Instruments International

Cold Rolling Mills
More information . In case of stainless steel, the process is more complex, with previous stages passing through a previous heat treatment of the coils, in bell furnaces, after the hot rolling process, reaching cold rolling mills with input thicknesses between 2.5 and 8.5 mm to be later cold rolled with target thicknesses between 0.25 and 6 mm. The cold rolling Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and Cold Rolling an overview ScienceDirect Topics
