Facts: Evans owned a mill located upstream from Merriweather's mill. Merriweather bought his property after Evans built his mill. When the stream that powered and provided water to the mills began to dry up, Evans' employees diverted all of the streamwater into their own well—causing Merriweather's mill to become useless.

Fuzzy goals and fuzzy constraints can be defined precisely as fuzzy sets in the space of alternatives. A fuzzy decision, then, may be viewed as an intersection of the given goals and constraints. A maximizing decision is defined as a point in the space of alternatives at which the membership function of a fuzzy decision attains its maximum value.

(cement). Normal temperature of kiln is to be maintained at 800-960 °C and a normal coal feeding is 10-20 t/hr. There are four basic processes in cement manufacturing. It starts with quarry where the raw material is extracted and crushed. Then it will be sent to raw …
Recently, electro-hydraulic actuators (EHAs) have shown significant advantages over conventionally valve-controlled actuators. EHAs have a wide range of applications where force or position control with high accuracy is exceedingly necessary. Besides the benefits, however, EHA is a highly complex nonlinear system which causes challenges for both modeling and control tasks. This paper …

The cement plant is one of the most energy-intensive industries, and the rotary kiln consumes significant share of this energy and the amount of consumed fuel has a direct effect on the finished product price (Radwan 2012).The cement plants consume high quantities of power which shape approximately 40% of the total production cost (Chatterjee and Sui 2019; Zanoli et al. 2016b).
Set a small diameter circle and a relatively high feed rate and you'll get lots of direction reversals to use for tuning… I got my mill X and Y axes up to 50 in/sec/sec or 0.13g's acceleration with the o-scope. Without it, I could only get to maybe 40'ish by ear. Z has the heavy mill head, so about half this much acceleration is ...
Cement manufac-turing is highly energy demanding, and is dependent on the availability of natural resources. Typically, the consumption in a modern cement plant is between 110 and 120 kWh per ton of produced cement [1]. The grinding stage represents about 40% of the total electrical energy consumption of the cement manufacturing.
