In Rulmeca, both idle and driven rollers are available to set curve roller conveyors. The first are basically meant to guide and support the conveyed material around corners, especially on light radius curve, not having a driving force. The latter are driven by chains or round, toothed, poly-v belts, guided via pinion sprockets or grooves ...

1 HP = 0.746 kilowatts = 0.746 kW. A previous Rulmeca video showed how a 150 foot long conveyor with a 30 inch wide belt and a 10 HP drive system, originally installed to carry 575 tons per hour (tph) at 300 fpm, could be upgraded to handle 800 tph. Option one recommended that the conveyor be fully skirted while maintaining a 300 fpm belt speed.

A flux vector VFD drives each Motorized Pulley. They were originally programmed to drive the conveyor at 60 Hz. At that time, the reclaim conveyor, fed by six belt feeders, moved "high calcium" hard rock and a mixture of other ingredients at 500 tph at a nominal belt speed of 384 fpm during 10% of the available production time.

Rulmeca Technical Tip: Hopper Feeder Loading. This "technical tip" answers how to calculate the downward force a hopper will exert on a feeder conveyor. Downward Force equals the product of the active volume in cubic feet and the bulk density in pounds per cubic foot. The active parabolic volume may be approximated by a prism which …

This "technical tip" answers how to calculate the downward force a hopper will exert on a feeder conveyor. Downward Force equals the product of the active volume in cubic feet and the bulk density ...

0.276 x 15′ x (4″)2 = 0.276 x 15 x 16 = 66 lbs of material drag. To calculate seal drag, use this equation: 3 lbs/ft of board x 2 boards x board length of 15 feet = 90 lbs of seal drag. The total of these frictions equals 156 lbs. 66 lbs + 90 lbs = 156 lbs. Assume, in this example, that belt speed = 600 feet per minute.

This lesson presents arching theory, how to calculate hopper drag load, how to design hopper pressure relief, and how to calculate the power required to overcome hopper …

We solved the problem by installing a 50 HP drive system, designed to provide 50 HP at a 330 fpm belt speed at 460v/3ph/60 Hz. Available power when running the drive at 60 Hz or 30 Hz is now adequate. Required power at 330 fpm = 23.6 HP. Available power at 330 fpm = 50 HP at 60 Hz. Required power at 165 fpm = 20.3 HP.

Sometimes belt bounce would damage the belt and sometimes belt bounce would damage the feeder or feeder structure. Installation of both Rulmeca Motorized Pulleys was accomplished in one shift. As shown here, the drives are compact, only 24 inches in diameter. Each 75 HP model 630H internally-powered drive pulley weighs only 1,850 lbs …

This "technical tip" answers how to calculate the drag force exerted on a bulk handling belt conveyor by a mechanical belt cleaner. The Conveyor Equipment Manufacturers Association (CEMA) conveyor design manual states that belt cleaner drag may vary from 2 to 14 pounds per inch (lbs/in) of scraper-blade contact, depending upon the type of belt …

If the conveyor belt has a belt speed of 300 feet per minute (fpm), then we can calculate required power as follows. Required Power = 300 pounds of drag x 300 fpm of belt …

Here, the main factors related to the essential issue of selecting the right motor for the conveyor are the type of transported material and the operating environment. Mines, cement industries, sugar and salt plants, steel and power plants and ports are all constantly exposed to very critic and aggressive conditions: transportation of high load ...

Factors to Consider in Belt Feeder Design. Several factors influence belt feeder operation and reliability: Head Load. Head load is the single most important factor in belt feeder design. The head load is the amount of pressure put on the belt directly under the hopper opening as a result of the weight of the material resting on the belt.

estimation of loads on feeders used in conjunction with funnel-flow, expanded-flow bins and gravity reclaim stockpiles is discussed. The design of feed chutes for directing the flow of bulk solids from the feeder discharge onto conveyor belts is briefly reviewed. 1. INTRODUCTION . Feeders have an important function in belt conveying operations.
