CEMA C5 specifications. SERIES 3000 DIMENSIONS FOR CONTINUOUS OPERATION, HIGH CAPACITIES, AND HEAVY, ABRASIVE MATERIALS Continental series 3000 belt conveyor idlers are for continuous operation, high capacities, and heavy, abrasive materials where lump size is limited by the width of the belt. Troughed belt idlers may be furnished with ...This type of structure is available for 36" up to 72" belt widths. The idlers attach to the steel frame using bolt-on, clamped or pin and cuff components. Rigid rail structure is known for its easy and quick installation. Depending on speed and tonnage requirements, rigid rail structure comes in CEMA B through CEMA E+ arrangements.

The CEMA historical method allows the designer to select an appropriate percentage of sag between the carrying idlers, to prevent lumps or material from coming out of the conveyor belt. The three values CEMA provides are 3%, 2%, and 1.5% sag Those percentages are based on material lump size, the proportion of lumps vs. fines, and the idler ...The information presented in this book is intended to cover the basic principles of belt conveyor design and to include such formulas, tables, charts and recommendations as are required to design most belt conveyors. The material is arranged in the order most convenient for the use of an experienced conveyor engineer.

ANSI/CEMA Standard No. 402-2003 (R‐2015) –Belt Conveyor – Unit Handling Conveyors III FOREWORD Belt conveyors--conveyors which use a belt as a carrying medium--are used for the controlled movement of a great variety of regular or irregular shaped loads, from light and fragile to heavy and rugged unit loads.CEMA agrees with the second bullet point above and adds four other economic points. Beyond 1 km distance, the ton-mile cost of transport by belt conveyor may be as low as 1/10th cost by haul truck. Estimated operating maintenance cost per year for a belt conveyor is 2% of the purchase cost plus 5% of the belt cost.
