The chart above illustrates the distance/length requirement for the level of incline on an inclined conveyor. In addition to a lower profile, the "L" and "S" configurations of the steep incline conveyor allow it to replace multiple pieces of handling equipment; one S-type steep incline conveyor can replace two belt conveyors and a bucket elevator, significantly reducing the overall ...
Normally short in length, Screw Feeders are designed to regulate the volumetric rate of material flow from a hopper, bin or storage unit. The inlet is usually flooded with material ( load capacity) but by incorporating changes in the construction of the flighting (diameter, pitch, etc.) and the speed of the feeder screw, the material discharge can be governed to the desired rate.

Therefore, in high tension applications, it is often preferable to consider an Apron Feeder or a hybrid Apron Belt Feeder solution. These feeders utilise chain as the main tension member, allowing smaller diameter sprockets at the terminal ends when compared to a belt pulley designed for high belt tensions.
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.

One Technology Park Drive • Westford, MA 01886-3189 • Tel: (978) 392-0300 • FAX: (978) 392-9980 ... 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
Along with our other vibratory equipment, vibratory feeders are great problem solvers. Feeders are well-known for their ability to move material from point A to point B effectively. However, a well-designed vibratory feeder offers flexibility to the end-user and increased safety and efficiency in the process. Feeders can range from small base mounted …
We can break the screw feeder design down into a couple of broad categories, a simple screw feeder and a mass flow screw feeder. ... pitch through the inlet and feeder shroud. Assume a 2″ dia drive shaft and a 2 ½" (2.875″ OD) center screw shaft For the sizing calculation we want to calculate the worst-case scenario, meaning using the ...

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.
Therefore: SC = 1.50 X 3.75 X 333 ft 3 /hr SC = 1,873 ft 3 /hr. The Selection Capacity will be used to select the proper screw conveyor diameter and speed from the Capacity Table. With a recommended trough loading of 30A, the Selection Capacity must be less than the maximum capacity given in the Capacity Table.
The apron feeder with arched plates is the perfect equipment for conveying sticky raw materials such as gypsum, anhydride, clay or a marl-clay mix. The arched plates of the feeder form a surface perfectly matching the drive and tail sprockets, hence allowing cleaning of the plates with a scraper. Fitted with a weighing rail and a
Housing & End-plates. Rotary valves are made up of 4 main parts; cylinder (or housing), end-plates, rotor, and drive package. Magnum Systems' rotary valves are made from cast gray iron, stainless steel and or Hard Chrome. The reason the housings are made out of a cast mold is the strength it adds to the design that is not possible if just fabricated.
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 ore/rock, bulk …
