Operator Responsibility The operator’s responsibility does not end with efficient production. The operator usually has the most daily contact with the equipment and intimately knows its capabilities and limitations. Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or through a casual attitude toward machinery formed over a period of months or years. Your employer probably has established a set of safety rules in your workplace. Those rules, this ma

Safety Circuit Standards Safety circuits used in industrial systems protect the operator and maintenance personnel from dangerous energy. They also provide a means of locking out or isolating the energy for servicing equipment. Various agencies have contributed to the establishment of safety standards that apply to the design and manufacture of automated equipment. The Occupational Safety and Health Administration (OSHA) and the Joint Industrial council (JIC) are just a few of the organiz

Examples: This example shows how to extrapolate a desired feed rate of 3 lbs./hr., based on the feed rates of 3 trial rpm settings. Observed Feed Rates Sample 1 = 2 pounds per hour @ 20 rpm Sample 2 = 4 pounds per hour @ 40 rpm Sample 3 = 6 pounds per hour @ 60 rpm In this example, a feed rate of 3 lbs./hr. would be about 30 rpm. 8 Calculated 7 feed rates 3 6 (lbs/hr) @ the 5 2 trial RPM 4 4 3 1 2 1 0 10 20 30 40 50 60 70 0 Trial RPM settings Additive F
