McLanahan offers a large selection of feeders that are designed based on a producer's material size, weight and desired throughput. The feeders deliver material to a conveyor belt or crusher at a rate that matches the capacity of that machine. McLanahan feeders can be incorporated into an extensive number of combinations to produce systems ...

material assumes while the material is at rest on a moving conveyor belt. Thus belt's ability to accommodate material is governed by surcharge angle instead of repose angle. In general, the surcharge angle is 5 to 15 degrees less as compared to repose angle. However, in some materials it may be as much as 20 degrees less. Abrasivity
