All Apron Feeders include an electric motor, a reduction mechanism and often a speed adjusting device. The feeder is driven by a conventional frequency-controlled electric motor and a planetary reducer, or by a hydraulic drive.
Generally, apron feeders are a high-torque low-speed application, and many older models use multiple reducers, chain and sprocket sets, open gearing, countershafts, etc., to achieve the necessary mechanical advantage. Spare parts inventory requirements are high and older parts can often become obsolete and difficult to source.
Examples of feeders include a belt feeder for coal, a vibratory pan feeder for applying seasoning to chips, and an apron feeder for ore under a stockpile. ... Also, while conveyors typically operate at a constant speed, feeders are always capable of varying the speed of operation. As a result, feeders are capable of modulating the discharge ...
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. With sealed-for-life undercarriage components and oversized head shaft bearings, the maintenance requirements on a McLanahan Apron Feeder are minimum.
In the case of belt and apron feeders, a tapered opening is required as illustrated in Figure 1. The triangular skirtplates in the hopper bottom are an effective way to achieve the required taper. The gate on the front of the ... flow rate is then controlled by varying the speed of the feeder. An alternative
Anti-friction spherical roller bearings are fitted to the head and tail shafts and housed in heavy duty plummer blocks. Bearings are grease lubricated and a grease reservoir is included in the design of the bearing housings and end caps. The Apron Feeder has a remote mounted electrically operated automatic greasing system as standard.
The drive system is available as an electro-mechanical and hydraulic drive and features an optional variable speed drive (VSD). With a segmented drive sprocket for easy exchange, you also benefit from easy maintenance. Our Apron Feeder SAF's pans are welded from high wear resistant steel.
Apron feeders are a volumetric type feeder, which means bulk density is used to determine the speed and power (torque) needed to extract a certain tonnage per hour (tph) of material.
Apron feeders are variable speed from zero to maximum to regulate the feed to your plant + Directly load Unrestricted performance. Our Apron feeders allow direct dumping onto the apron plates even when empty of material + Heavy duty Built to last.
apron feeders are equipped with lubed-for-life chains and . rollers ranging in size from D4 to D11, ensuring a high degree ... The speed of the apron feeder is controlled via a frequency converter, allowing the speed to be infinitely reduced to 25% of the nominal speed. With hydraulic drives, the speed ...
Agnico Eagle approached in 2020 to replace the first of three originally installed apron feeders of a different brand at its Meliadine site after three years in operation due to their high operating cost. Following this first successful replacement with 's high-quality, durable, and reliable apron feeder, the second apron feeder ...
Apron feeders are designed to be ran at variable speeds to extract from storage and feed downstream at a controlled rate of speed for maximum efficiency. The material could vary depending on factors such …
Apron feeders are typically designed to run continuously up to 50 FPM (0.25 m/s) whereas belt feeders would be up to 100 FPM (0.50 m/s). Under normal operation, the speed range used is normally a 3 or 5:1 turndown.
Osborn apron feeders accurately control the feed rate to prevent surge loads to the primary crusher or other processing equipment. These feeders feature a rugged, heavy-duty construction and are designed to handle feed sizes of up to 60" (1,500 mm) where no fines removal is required or where fines are removed by a separate vibrating grizzly.
In thyssenkrupp apron feeders the drive shaft is journaled in heavy-duty, double-row spherical roller bearings and housings. thyssenkrupp apron feeders are equipped with either hydraulic or electric motors. All drives are designed to allow starting even under load. From top: Apron feeder RKF 3.0 x 8.3 - D10 during shop assembly
Apron Feeders are available in six chain sizes, 16 standard flight widths, and an infinite . range of lengths - all designed to meet a customer's application requirements. ... Speed of the belt is approximately 20 ft/min (6 m/min). Drag Scraper To capture fine wet material that may filter between the flights, a drag scraper can be . provided ...
Considerable speed reduction from elec-tric motor to drive sprocket is obtained, in this case, applying the hydrostatic transmis-sion and one stage reducer. The application of variable displacement hydraulic pump enables the speed regulation of apron feeder so that during start of drive, the apron feeder works with a minimum speed, and nominal
