Apron Feeder drive systems can be supplied in electro-mechanical or hydraulic drive to match the duty and requirements of the application. The Apron Feeder comes with standard e-stop pull cords and a zero speed sensor. Optional features include a dribble belt or drag scraper to capture any material that may filter through the flights.
Late 19th Century: The first use of feeders dates back to this period, with apron feeders emerging as a solution for the handling and processing of materials. Early 20th Century: Utilized in cement and mining industries. First Quarter of 21st Century: Became the most widely used feeder for first-stage crushers. Apron Feeder Design and Components
7.4 APRON FEEDERS An apron feeder is essentially a leakproof, or non-leak, type feeder. The standard design allows 'f16-in. clear ance between the overlapping pans. These pans are at tached to two strands of roller chain, and the apron sup porting frame is designed to have stationary side plates to form the feeder sides. Apron feeders are ...
methods for determining feeder loads and power requirements are presented. The interaction between the flow pattern developed and wall pressures generated in mass- flow hoppers and the manner in which these influence feeder loads is discussed. A simplified methodology is presented for the design of belt feeders and feed hoppers with
Hybrid feeder is a combination of our Samson® Feeder with a heavy-duty Apron Feeder. Wide range of bulk materials: fine, sticky, high bulk density. With the lateral arrangement of the bearing chains and special shape of the plates, there is the significant reduction in the total height of the feeder. Protection against spillage is provided by
Drive Power Calculation of Heavy-Duty Apron Feeder For heavy-duty apron feeders, the calculation of power is very important in terms of drive, and it is more prominent in many aspects.In the current stage of mining and transportation, the requirements for transportation volume are constantly increasing. If there is a deviation …
This calculation method can avoid the possibility of overload on apron feeder during peak kiln load, but in the normal production process, due to the relatively low probability of kiln skin loss or punching, apron feeder will only work at 50% to 67% of its theoretical transmission capacity during most working hours. Resulting in an …
Apron feeders are volumetric-type feeders, which means bulk density is used to determine the speed and power needed to extract a certain tonnage per hour of the material. The minimum bulk density is used to determine the speed, and the maximum bulk density establishes the power (torque) needed for the feeder.
These design calculations go beyond industry accepted standards, and included detailed calculations for feeders, conveyors, inclined conveyors, deflections, shaft sizing including stress concentration factors and calculation of demand and motor power requirements. ... Apron Conveyor; Apron Feeder; Air slide; If there is a particular type of ...
Common feeders include screw, belt, apron, rotary ploughs and vibrating feeders. The rate of material being discharged is most commonly controlled volumetrically from these feeders; therefore, it is also critical to use the correct bulk density from test results to ensure the required flow rate is met.
Basic Apron Feeder / Belt Feeder Design Calculations If you would like more information, please fill out our Apron Feeder / Belt Feeder Design Calculations Form and we will do our best to offer our suggestions If you prefer a copy of our ...
Universal Apron Feeders are still designed and built with the same quality. Universal Apron Feeders are engineered to meet each customer's specific application, ranging from light-duty to severe-duty. They provide a positive, constant, metered material flow. Apron Feeders are ideal for a wide variety of
Vibratory feeders are used in gravimetric feeding systems to handle solids with particles that are loo large to be handled by screw, rotary-vane, or vertical-gate feeders, or in operations where the physical characteristics of the solid particles would be adversely affected by passage through these volumetric feeding devices. The discharge …
Located to form a bin bottom, Rexnord Apron Feeders permit drawing on stored capacity when and as needed. The heavy-duty design provides strength and ruggedness to withstand abrasion and high loading. Rexnord Apron Feeders – The Industry's most preferred feeder. Look to Rexnord for the right answer to bulk material feeding solutions.
The key to proper screw feeder design is to provide an increase in capacity in the feed direction [4]. This is particularly important when the screw is used under a hopper with an elongated outlet. One common way to accomplish this is …
Apron Feeders are a robust style of feeder that can be used to feed or extract material in a wide variety of applications. Apron Feeders excel at handling material that is beyond the scope of other feeders. ... Information critical to the power calculation and design of an Apron Feeder includes type of material, feed rate, size of material and ...

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.
