Case Study Vibrating Screens Exciter Bolts Vibrating screens provide a vital service in the mining industry, they are critical to operating efficiency. They operate with exciters that generate very high G-forces typically 3-5Gs, consequently the structural bolting needs to withstand these forces.
Vibrating screen equipment in mineral processing has a tough job. The eccentric motion with high vibration coupled with heavy loads puts a strain on components, and especially bearings that are exposed to the elements and abrasive dust. Its an environment where equipment failure is often accepted as a cost of doing business.
NRM liquid vibrating screens use fine screen cloths, up to 120 mesh. Maximum liquid passing with minimum blinding is assured. Separation of solids from liquids is highly efficient. Model NRM screens are built for a long, productive life. The screen box and deck are made of welded, low alloy steel, reinforced with heavy-duty pipe.
Vibratory Screens. Circular vibrating screen or round vibrating screen is a multi-layer, highly efficient and new vibration screen machine that moves on a circular motion. It adopts drum eccentric shaft exciter and eccentric block to adjust the vibration amplitude, so that the screening line is long and the screening specifications are more.
