Although design calculations may indicate overcapacity, no conveyor in any crushing plant should be less than 0.5 meters wide and, in actuality, it is best to standardize on a minimum belt width of 0.67 meters throughout the crushing system. Design should be such that conveyor troughing and return idlers can be lubricated from one side. Barely are small conveyors designed and manufactured with walk-ways on both sides of the belt. In smaller installations some designers prefer to specify permanently self-lubricated idlers. The design of tail pulleys should be oriented toward ease of cleanup. The lowest point of any belt should be at least 0.6 meters above the floor. Rock deflectors or plows located immediately in front of tail pulleys above the returning belt can serve to prevent rooks from cycling between the belt and pulley thereby increasing belt life. In tunnels, beneath stockpiles, and in other locations below grade, provisions must be made to include the cleanup sumps and pumps. In addition, these locations should be protected from flooding. Counterweights and/or mechanical takeups must be positioned in accessable locations for ease of adjustments. Usually gravity takeups are preferred since they tend to be self-adjusting and minimize sideways belt movement. Conveyor layout must take into account wind direction and, for elevated conveyors, covers should be considered. Naturally, all conveyors must be equipped with emergency shutdown switches and all drives, sprockets, and gear trains must be provided with adequate guards. The emergency stop cable should run the length of the belt on the operating side. Conveyor interlock systems must be carefully designed and must be understood by all operational personnel.
