To calculate this, multiply the number of times you use your treadmill over the course of a month by the maximum treadmill wattage. For example, if you use a 600-watt treadmill for 18 hours every month, your treadmill will use 10.8 kilowatts. With this formula, you'll be able to easily discover this cost on your electricity bill.
Energy consumption for grinding wheat straw, corn stover, and rice straw increases when screen opening size are changed from coarser to finer (Arthure et al., 1982).

The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by …
feeding (e.g., making metering into the mill difficult), grind-ing (e.g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the bag filters). There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and
Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power ...

In the process of grinding hammer mills are used to realize the shredding using impact between grain and hammer. This process is complex, fragmentation of the grains depends on a number of factors, such as grind material, its moisture, mesh size and mode of operation of the mill. These factors inluence energy consumption in the grinding process.
