However, within the investigated parameter range no negative influence on the yield was observed. Up to 50% of VB,total can be taken over by the substrates in addition to 30% for the total milling ball volume. Scale-up factors of 15 and 11 were realized considering the amount of substrates and the reactor volume, respectively.
A waste disposal facility for process industries is an important factor, which influences the plant location. ... (humidity, temperature). Climates greatly influence human efficiency and behavior. Some industries require specific climatic conditions e.g., textile mill will require humidity.
THE INFLUENCE OF MILL SPEED AND PULP DENSITY ON THE GRINDING EFFICIENCY 89 Pilot plant description The milling pilot plant consists of two containers mounted on top of each other (see Figures 1 and 2). The bottom container holds the mill, the drive train, rollers and the high-tension cabinet. The feed boxes (fine and coarse feed) are built into the
2. Factors affecting demand. Some major factors affect demand in microeconomics. Besides price, demand for a commodity increases or decreases due to the factors below. a. Income. The demand for goods and services also depends on the incomes of the people. The greater the incomes, the greater their demand will be.
In drilling and milling, the surface is the outside diameter of the tool. In turning and boring, the surface can be defined on either side of the depth of cut (the starting surface or end surface). Cutting speeds are expressed in feet per minute (imperial) or meters per minute (metric).
Service factors for synchronous belts run a bit higher, ranging from 1.0 to 2.4. Another synchronous belt consideration Service factors for synchronous belts are higher than those for V-belts.
young people and adults even in developed countries. Some of the factors influencing child health and development are summarized in Figure 1. As evidence from Scandinavian countries and poor countries, such as Cuba and the Indian state of Kerala, has demonstrated, it is the elimination of these factors that will have most effect on child health ...

The degree of cleaning is influenced not only by the lint characteristics in intermediate products, but also by the mechanical handling of the fibre [3,4], because cotton has a lower degree of cleaning DC (%) if it is difficult to clean (bad cleanability) andor if the machine has a lower cleaning efficiency.
The efficiency of an enzyme is largely influenced by the pH value of its surroundings. This is because the charge of its component amino acids changes with the change in the pH value. Each enzyme becomes active at a certain pH level. In general, most enzymes remain stable and work well in the pH range of 6 and 8.
