study on vibratory feeders: calculation of natural,is complicated and the exact calculation of spring constant is difficult. in this paper, an approximate calculation is made and some relations between natural frequency and the setting condition of the spring are shown. these results will be useful for design, development and practical use of bowl-type feeders. 2..calculation method to design hoppers and silos,feeders are positioned after a hopper to control the discharge, dose the solid if necessary, or reach another unit operation while reducing the height of the installation (case of screw and vibrating feeders). 4 feeders are considered here and cover most of the cases in the industry : simple butterfly valves, pneumatic rotary valves or airlock rotary valves, screw feeders and vibrating tubes..everything you need to know about apron feeders,the apron feeder is the most robust feeder in the mining industry under 24/7 operation, with years between maintenance periods. an apron feeder and triple roll crusher. history of the apron feeder. apron feeders had been operating in the aggregate industry for a while when national iron company (nico) designed and developed their apron feeder.

apron feeders are designed and manufactured to handle heavy, lumpy and abrasive materials. its main function is to prevent surge loads to primary crushers, belt conveyors and other equipment. apron feeder consists of drive wheel device, tail wheel tension device,pan- chain device and transmission device. after the head sprocket is driven, the
in mining, the apron feeder carries rocks and minerals for crushing or further processing. at a factory, these machines may be used to add ingredients to a food or other mixture. because of their heavy-duty design, apron conveyors are also a popular choice for transporting concrete and stone for crushing, recycling, or mixing.
selection and calculation of apron feeder. 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 sufficient strength of the heavy plate feeder itself including rack, chain plate

normally, the optimal speed an apron feeder is 0.05 – 0.40 m/second (10–80 fpm). if the ores are non-abrasive, the speed can increase to above 0.30 m/second because there will be less wear. higher speeds would hurt an operation. if your speed is too high, you run the risk of accelerated wear of components. energy efficiency decreases due to

6) always need variable speed drive. so, maximum of variable speed range should correspond to capacity, which could be about 20% more than the guaranteed capacity. that means will normally run below maximum range by certain margin. this provides room for selection of speed during field trials / setting.
