Proper sizing and selection of an apron feeder can be a tough task For your operation if the size of your apron feeder is not selected correctly, then that can result in loss of production and profitability Martin Yester gives us some insight on how to make sure sizing and selection of your apron feeder will bring maximum results to your operation
High shear force will increase the starting torque of apron feeders a minimum of 100% — and 50% to 75% for belt feeders Coarse ore feeders withdrawing materials of greater than 305 mm in size may require additional starting torque (figure 5) In addition to starting torque, allowance should be made for filling pressure (figure 6)
Biomass Ram Feeders A reliable fuel feed system is critical to proper furnace combustion control and furnace operation As furnaces age, deteriorating feeders contribute to deteriorating combustion conditions, and in the most extreme case can jeopardize personnel and equipment

When sizing feeder drives, a major factor is the necessary starting torque High shear force increases starting torque compared to running torque, often by more than 100% on apron feeders and by at least 50-75% on belt feeders If coarse ore and larger materials are ,
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
Identifying the hopper shear length is a key component for correctly sizing and selecting an apron feeder and drive system (motor) But, how can this be determined? The hopper shear length is the dimension from the back plate of the hopper at the skirt line to the shear bar located at the exit end of the hopper

It will only provide a maximum torque before it slips This torque relates to a linear force If that linear force is greater than the frictional shear force between two sheets of paper, it strips the bottom sheet If the linear force is less than the frictional shear, the second sheet is unaffected
Jan 22, 2015· (see photo of belt feeder interface) Product Flow As product flows down through the interface, since the major principle stresses are more-or-less horizontal, the vertical stresses acting through the shear plane are relatively low This allows the belt to shear the product efficiently with a minimum amount of force
Consider these two plates that are bolted together The force F is trying to separate them as shown The bolt connecting the two is subjected to a shear force across the plane that separates the two plat There is shear only at this plane of the.
This subjects it to an even higher shear force, due to the higher speed of the apron roll and typically, a smaller gap than between the feed and centre rolls A knife blade then scrapes the processed material off the apron roll and the paste rolls down the apron This milling cycle can be repeated several times to maximize dispersion
