An overview of feeder design and performance focussing on belt and apron feeders is presented The importance of correct hopper and feeder interfacing is stressed The objective is to achieve uniform draw-down in the hopper and procedures for achieving this objective are given For the belt and apron feeder, the required divergence angle for the interface …
Basic criteria that should go into properly sizing an apron feeder should include feed rate (peak and normal), material characteristics (such as moisture, gradation and shape), maximum lump size of the …
Apron feeder can be divided into heavy, medium and light apron feeder, which featuring in large granularity, bulk density and delivery capacity of conveying material, generally above 600U h. This also determines the …
Maintenance is easy. Only a short time is required to change the apron or conveyor chain. Total operation and maintenance costs are low. Capacities from 1.6 t/m for apron feeders for feeding crushed stone with varying bulk density, are available. Capacities and motor outputs vary depending on the length of apron feeder and the apron speed.
Motor capacities are designed taking that efficiency of the speed reducer, speed variator and the power transmitting system into account. Normal inclination is 80 upward. Fig. 1 shown the apron, conveyor chain and feed drum. Fig. 2 shows the various parts of einen select serious duty apron feeder. Design, dimension and power calculation for the ...
Two impact rails are typically used on feeders 60" (1524 mm) and wider that have direct impacting. (Note: no impact rails furnished with 24"and 30"widths). Heavy-Duty Chain Crawler tractor-type chain is used on all models of apron feeders. This chain features hardened links, pins and bushings, all made from heat-treated alloy steel.
- The AF apron feeder has heavy-duty roller supports throughout the full length of the feeder and a double set of rollers in the impact area - All rollers are fully automatically lubricated - A hydraulic take-up system ensures perfect and consistent tension-ing of the chain - Two apron feeders can be combined to form a raw material blending
McLanahan 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 requirement. ... Information critical to the power calculation and design of an Apron Feeder includes type of material, feed rate, size of material and more. ...
The most direct and effective way to reduce the chain tension is to control the feed thickness of the heavy apron feeders, and the following example shows the relationship between the thickness of the material layer and the circumferential force of the drive wheel. Design a 2 400X28000 heavy apron feeders, known: production capacity Q = 4500t / h, …
apron feeders brochure provides detailed information on the features, benefits and applications of 's robust and cost-effective apron feeders, designed to handle the most challenging materials in mining, aggregates and recycling industries.
wet, sticky or frozen operations, apron feeders work well across a wide variety of applications. "Tractor chain" style feeders – the industry's preferred design Tractor chain style feeders are the preferred design and set the standard for an almost maintenance free feeder. This style of apron feeders have dominated the market in
A tractor chain style apron feeder refers to the undercarriage chain, rollers and tail wheels that are also used in bulldozers and excavators. ... To conclude, it is important the correct "bulk" density and …
Dozer chain is typically used for its strength and reliability. Sprockets utilized by PPI work with standard chain sizes including: D2, D4, D6, D7, D9, D10, and D11. PPI produces the drive and idler shaft assemblies (not the apron feeder) for many of the largest OEM's supplying apron feeders to the market.

MEKA Apron Feeders provide reliable means of controlling the feed rate to prevent surge loads to the Primary Crusher or other plant equipment. An Apron Feeder is run at very low speeds and at a controlled feed rate as it absorbs the impact loads of the material falling from a dump truck or a front-end loader. Apron Feeders are of rugged, heavy ...
design of chain drive system in a heavy duty apron feeder of mobile crushing station. 2. THE THEORETICAL ANALYSIS An apron feeder bears huge loads in work conditions, and any speed fluctuation may cause immense impact loads and the damage of roller and sprocket. This section only focuses on the speed fluctuation originating from the polygonal
1.3.2 Apron feeders Figure-1E shows the apron feeder. The apron feeder is used for dealing with materials which are very hard, abrasive, tough and for lumps of larger dimensions; which are beyond the scope of belt feeders. The boulders of even 1.5 m edge length dimension can be handled, because such lumps will be falling and carried by steel …
