Material compacting apparatus
Abstract
Abstract A MATERIAL COMPACTING APPARATUS INCLUDING OPPOSED COMPACTING ROLLS MOUNTED FOR LATERAL DISPLACEMENT TO VARY THE SPACING BETWEEN THE ROLLS DEPENDING UPON THE PRESSURE EXERTED DURING COMPACTING. A HOPPER IS POSITIONED ABOVE THE ROLLS FOR HOLDING THE MATERIAL, AND A FEED SCREW IS LOCATED WITHIN THE HOPPER FOR FEEDING THE MATERIAL TO THE ROLLS. CONTROL MEANS ARE PROVIDED FOR VARYING THE DRIVING ACTION OF THE FEED SCREW WITH THE VARIATIONS DEPENDING UPON ANY TENDENCY OF THE PRESSURE APPLIED BY THE ROLLS TO VARY. THE FEED SCREW IS HYDRAULICALLY DRIVEN AND SIGNALS ARE APPLIED TO THE FLUID DELIVERY MEANS FOR VARYING THE FEED SCREW PRESSURE. VARIATIONS IN THE DRIVING FORCE OF THE FEED SCREW ARE DESIGNED TO OFFSET THE FORCES TENDING TO VARY THE SPACING BETWEEN THE ROLLS WHEREBY A CONSTANT ROLL SPACING, AND THEREFORE A PRODUCT OF CONSTANT THICKNESS CAN BE ACHIEVED.
