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 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 the preferred feeder for several reasons, but there are a few that are commonly seen throughout the industry. Aprons provide better feed control to prevent material feeding in ...

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 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.
Apron feeders are built for reliability and performance in any duty needed in mining. With over 120 years of experience in material feeding, has developed a global standard in apron feeders. Our robust design …
From the formula (4) and the design input parameters provided in Table 1, the unknown design parameters need to be completed are: D screw blade diameter, s is the pitch of the screw blade, N is the rotation speed of the screw assembly shaft. The design and calculation formula of screw blade diameter is as follows: ρC Q D K2.5 (5)
