Rubber Track Undercarriage

Machine stability and engine life are adversely affected if operated on slopes greater than 3-to-1. On a flat surface (Illus. 1), machine weight is spread through the roller wheels to the full ground contact area of the track. Minimal machine weight is applied to the track lugs. However, on slopes (Illus. 2), machine weight will shift, and the

Scale up in froth flotation A state of the art review

Feb 08, 2019 This review indicates that current scale-up rules governing the design of flotation tanks focus mainly on pulp zone kinetic parameters and neglect the effects on the froth zone, despite the importance of froth stability and mobility in determining flotation performance. Froth stability and mobility are closely linked to the distance the froth needs to travel, which increases with tank diameter.
