Abstract
In the present era, many industries are demanding material transfer equipment that works maximally and cheaply. Belt Conveyor is one of the most efficient material transfer equipment compared to heavy equipment or other transportation equipment, because it can transport the material in large capacity. When designing conveyor belts, many industries want large transport capacity at low cost. One of the cost savings can be done with low motor power consumption. Many standards describe the effective tension calculation on the conveyor belt in detail with the parameters, since the effective tension calculation results are essential for determining motor power. This paper aims to analyze the effective tension on conveyor belts using CEMA 5th, CEMA 6th and DIN 22101 standards with case studies of 1000 TPH carrying capacity and 3 m/s conveyor speed. The difference between CEMA and DIN when determining the effective tension is on the use of coefficient of friction, because DIN uses a global coefficient of friction while CEMA uses different friction coefficients on idler, belt and material. This difference in coefficient of friction results in different ways of calculating the resistance being the accumulation of the effective tension. The result is an effective tension value using DIN 22101 standard of 22,148.16 N with motor power consumption of 66.5 kW, while effective tension value using CEMA 5th standard is 32.201.66 N with motor power consumption 96.47 kW, and effective tension value using CEMA 6th standard is 29,686.48 N with 89.06 kW motor power consumption.
Highlights
Material transport equipment is very important in this modern era of life, especially in helping a job to obtain maximum results
One of the cost savings can be done with low motor power consumption, where the motor power value is directly proportional to the effective tension value that occurs in a conveyor system
Problems to be investigated in this research include: effective tension calculation analysis on belt conveyor capacity 1000 TPH using standard Deutsches Institute Normung (DIN) 22101, Conveyor Equipment Manufacturer's Association (CEMA) 5th, and CEMA 6th, and determine difference of three standard in determining effective tension
Summary
Material transport equipment is very important in this modern era of life, especially in helping a job to obtain maximum results. The two most common design methods used to calculate the effective tension on the conveyor belt are the Conveyor Equipment Manufacturer's Association (CEMA) method [1] [2] and the Deutsches Institute Normung (DIN) method DIN 22101 Standard [3]. Based on these problems, it is necessary to conduct research that aims to analyze the effective tension on the conveyor belt using standard variations DIN 22101, CEMA 5th, and CEMA 6th. Problems to be investigated in this research include: effective tension calculation analysis on belt conveyor capacity 1000 TPH using standard DIN 22101, CEMA 5th, and CEMA 6th, and determine difference of three standard in determining effective tension
