6.1 Treatment of solid waste products. In a well run palm oil mill, it is expected that each 100 tonnes of FFB processed yields 20 to 24 tonnes of crude palm oil and about 4 tonnes of palm kernels. Thus between 72 to 76 percent of the FFB comes out at various stages of the process as waste. The solid wastes that result from the milling ...

• Another crude but very effective way to measure tension in the unwind zone is the "fish scale method". This method works for the unwind zone only. It can only be utilized if there is a brake on the unwind station. Unwrap a small amount of material off the unwind roll. Set the unwind brake to the torque output normally set for a machine run.
When grinding cement raw material the metallic particles usually cause uniform wear throughout their entire service life so that the mill throughput only declines when mill parts are completely worn. Partial wear may occur if, for reasons of cement chemistry, free quartz sand needs to be used as concrete aggregate.
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
