one of the world’s leading experts on the design of overland conveyors david kruse of advanced conveyor technologies inc (ac-tek) was recently in south africa to speak at the beltcon 15 conference held in johannesburg in early september.
the most economical location of a horizontal gravity takeup is at the tail of the belt conveyor. but on long overland conveyors the reaction time for tension effect must be taken into account. therefore it is desirable to nave the takeup as close to the drive pulley as possible.
the design of a conveyor system started halfway the 1950's. it was however not until halfway the 1980's that the first useful design tool became available. in the early days of using dynamics of belt conveyor systems the attention was focused on an analysis of both the starts and the stops of long overland high tonnage/lift/speed conveyors.

belt analyst ™. belt analyst ™ is a classic static analysis belt conveyor engineering tool used to develop the core system design criteria of any belt conveyor necessary for every successful application. all calculations are included from the most critical power requirements and belt tensions to the selection of each major component.
noise reduction is a key trade-off area in conveyor design with gerard saying noise emission from idler rollers is mainly due to the steel tube used being seam welded and not perfectly round. “extruded poly rollers are round but cannot withstand the loads from the wide idler spacing required for overland conveyors.

surface crushing and conveying equipment single-source supply of crushing and conveying equipment from komatsu provides an integrated system for maximum availability and productivity. a material handling system simple or complex will perform only as well as its component parts the engineering that went into its design and its installation.
the kennecott mine in bingham canyon utah has five overland conveyors in its conveyor route. all the conveyors are driven by wound rotor motors with step resistors. two conveyors have regenerative sections and are each powered by four 1125 kw motors with head and tail drives. the drives use a binary stack with seven elements and 22 steps.
most risk analysis will identify the transfer chutes as the biggest risk in any belt conveyor. getting the material loaded and unloaded for a conveyor is often left to last in the design process but should be moved to a very prominent position as the ramifications of a poor or well designed chute is paramount to the long term success of material transport.
designed and manufactured in-house at our state-of-the-art facilities each lorbrand conveyor idler and conveyor pulley is built with revolutionary technology—from centrifugal self-cleaning seals to the use of finite element analysis (fea)—for truly …
