Factors In The Selection Of Motors And Speed Reducers For Conveyor Drives ? Introduction

Conveyors constitute a critical artery, essential to the successful operation of most ore processing plants. Technological progress is permitting the recovery of metal from low grade ores which previously could not be worked economically. Significant in this progress are improved material handling techniques highlighted by the frequent and successful application of conveyors. From the standpoint of the plant manager the successful conveyors are those he never hears about. They continue to economically transport the loads applied to them, requiring only routine maintenance attention. When such conveyors are subjected to closer scrutiny you will find that they have been carefully selected and engineered to perform the required function under the anticipated conditions. Among the primary elements in a conveyor drive are the electrical motor and the speed reducer. The selection of these elements can be aided by the systematic consideration of several factors. These factors which focus attention on the critical operating conditions, will be individually evaluated and their effect upon the selection of the electrical drive system and speed reducer analyzed.
