If you know any 3 values (Pulley sizes or RPM) and need to calculate the 4th, enter the 3 known values and hit Calculate to find the missing value. For example, if your small pulley is 6" diameter, and spins at 1000 RPM, and you need to find the second pulley size to spin it at 500 RPM, Enter Pulley1 Size 6, Pulley 1 RPM 1000, Pulley 2 RPM 500, and hit Calculate to find the second pulley diameter.

Belt Feeders. FEECO offers heavy-duty belt feeders that are capable of handling nearly any material. Belt feeders are commonly used when material that is either stockpiled or loaded (at an uncontrolled rate) in a bin or hopper needs to be introduced into the system at a controlled feed rate.

[PDF]The feeding of bulk solids onto belt conveyors is normally controlled by a gravity flow hopper/feeder combination and, in the majority of cases, the solids are finally directed onto the belt through a gravity flow chute. The feed hopper may be a part of a surge bin as in Figure 1(a) or a part of a stockpile reclaim system as in Figure 1(b).

A beltweigher or belt weigher is a piece of industrial control equipment used to gauge the mass or flow rate of material travelling over a troughed (cupped) conveyor belt of any length which is able to adequately contain the material being weighed. These are also known as belt scales, dynamic scales, conveyor scales, and in-motion weighers. Many such check weighers or feed weighers are an ...

Calculation of Conveyor Speed. Conveyor Speed can be most conveniently calculated, by use of the nomographs supplied on pages. To use this nomograph – first locate the two known values (screw diameter, and required capacity, in cu. ft. per hour), then with a straight edge connect these two points.

Apron Feeders must always be employed to ensure that the feed to a crushing machine is drawn at a constant rate from the bin which serves it. Of the many designs in existence by far the most widely used are the apron and pan feeders, although the Ross Chain Feeder is .

[PDF]How to Design Efficient and Reliable Feeders for Bulk Solids by John W. Carson, Ph.D. and Greg Petro, P.E. A feeder is an extremely important element in a bulk material handling system, since it is the means by which the rate of solids flow from a bin or hopper is controlled. When a feeder stops, solids flow should cease. When a

• Feeding jaw crushers and belt conveyors • High-abrasion applications frequently found in reclaim circuits apron feeders should not be mistaken for "pan or belt feeders" that are typically used in light duty operations not requiring the benefits of a true crawler tractor-type feeder. The feeder is offered in various models ...

[PDF]Belt weighfeeder with metering hopper: Belt weighfeeders with metering hoppers have a controlled feeder which adjusts the amount of material on the belt. These metering hoppers, which may be chutes, augers, radial vane rotors or conveyor belts, feed precisely the right amount of material to the conveyor belt.

Motor Sizing Calculations This section describes certain items that must be calculated to find the optimum motor for a particular application. Selection procedures and examples are given. Selection Procedure First, determine certain features of the design, such as drive mechanism, rough dimensions, distances moved, and positioning period.

Continental weighfeeders are self-contained belt feeders with a controlled drive system, belt scale, speed sensor and integrator. They are designed to operate in either the shearing or wild flow modes of weighfeeding. In a shearing application the weighfeeder is designed to .

At MERRICK, we custom design and manufacture loss in weight feeders, belt feeders, volumetric feeders, and more that offer the reliability and accuracy that are required for cost-effective material handling. Our selection of loss in weight feeders includes: Single / Double Screw Discharge Rapid Change Over (Orbital) Integrated Scale (Model 570)
