Pulp and paper mill situated in the complex terrain of northern Slovakia, in the close vicinity of the city of Ružomberok, continuously releases to atmosphere 30 kg of water vapor per second. Impressive clouds above the industrial complex have given rise to concerns from the side of local citizens, suspecting the emissions to be responsible for the local increase in precipitation. Therefore, a ...

Mark Duffy produced a complete set of grinding data on pilot-scale tower mill. Here these are analyzed in terms kinetics. The results show that the can be fitted with simple first-order breakage model, which is not normally observed any system, including other types machines such as tumbling ball mills and rod mills. model has only two parameters, making it possible to determine parameters usin...

An empirical study of the bivariate probability distribution characterizing a full set of two consecutive price increments x and y for a group of stocks at time scales ranging from one minute to thirty minutes reveals asymmetric structures with respect to the axes y = 0, y = x, x = 0 and y = −x. All four asymmetry patterns remarkably resemble a four-blade mill called market mill pattern. The fo...

A huge number of workers are employed in traditional rice mills where they are potentially exposed to dust. In this study a dust collection system was developed to capture the airborne dust in the rice mill. The feeding and sieving section of the mill was identified as major dust creating zone. The dust was captured by creating suitable air stream at feeding and sieving sections of the mill and...
