STAIRS Design & Construction

"A Stair is a system of steps by which people and objects may pass from one level of a building to another." A stair is to be designed to span a large vertical distance by dividing it into smaller vertical distances, called steps. Some of the functional requirements of staircases are;


INTRODUCTION Stairs is a set of steps which give access from floor to floor. The room or enclosure of the building, in which stair is located is known as staircase. Staircase provide access & communication between floors in multi-storey buildings and are a path by which fire can spread from one floor to another.

Spiral Classifier for Mineral Processing

In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn't lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do. As it is revolved in the slurry the spiral is constantly moving the coarse backwards the fine material ...
