Pelletizing plant of the Gol-E-Gohar mining and industrial company consists of a burner, a dry ball mill (6.2 m × 13 m), and an air separator. The ball mill consists of a 2 m-long drying and an 11 m-long grinding chambers. The iron ore concentrate is fed to the drying chamber by a feed chute. It was found that when the feed moisture content increased from 1.3% to 3.5%, the throughput decreased ...

Two groups of feedlot cattle on two different mineral supplement trials were used to assess the relationship between temperament and cannon bone measurements. The cannon bones of approximately fourteen month old crossbred Bos taurus European, Continental, and British steers (n = 135), primarily Angus, Charolais, and Hereford breeds, and 54 Charolais x Hereford heifers were measured postmortem. ...

The effect of venipuncture on blood serum catecholamine concentrations was studied in five yearling Red Angus bulls. Treatments consisted of sampling jugular vein blood via indwelling cannulas in a squeeze chute every 10 min for 1 h; sampling jugular vein blood from an indwelling catheter before, during and after venipuncture simulation; sampling jugular vein blood by venipuncture in a chute af...

A two-dimensional depth-integrated theory is derived for the gravity-driven free surface flow of cohesionless granular avalanches over complex shallow basal topography. This is an important extension of the one-dimensional Savage–Hutter theory. A simple curvilinear coordinate system is adopted, which is fitted to the ‘mean’ downslope chute topography. This defines a quasi-two-dimensional refere...

In this paper, 2-D simulation of a 61 m long inclined snow chute flow and its interaction with a catch dam type obstacle has been carried out at Dhundhi field research station near Manali, Himachal Pradesh (India) using a commercially available computational fluid dynamics (CFD) code ANSYS Fluent. Eulerian non-granular multiphase model was chosen to model the snow flow in the surrounding atmosp...

A chute is characterized by a steep bed slope associated with torrential flow. This chute flow may be either smooth or stepped. The flow conditions in stepped channels are classified as nappe flow, transition flow and skimming flow. In this paper, hydraulic characteristics of flow regimes on the stepped channels are presented systematically under a wide range of discharge, channel slope and ste...
