Activation of the entire hopper section allows a shallow hopper design to be employed. This may be supplied with a low, controlled-volume injection during storage, to stabilise the flow condition whilst the material is static, and increase the degree of aeration by injecting a higher rate of air for discharge.
Hopper design problems are normally one of two types; either the material does not discharge adequately from the opening in the hopper or the material segregates during the flow.

Description: The Bag Dump Hopper provides a quick, easy and virtually dust free way of dumping and filling your process system with material received in paper bags. The design incorporates a baffle and bin vent (to attach to a central dust collector) or optional bin vent filter over the dump area
The weigh hopper which weighs the material before dumping onto the HDPE bags is of SS316 material.This powder is sticking on to the weigh hopper causing the inaccuracies. Can we use Teflon lining on the SS316 material to avoid the sticking problem or can any other coating material be used.
The best type of slide gates to install below surge hoppers are Roller Gates for sticky materials, or Orifice Gates if you need to seal differential pressures. Vortex Roller Gates used to close off material flow from a hopper in a flour mill.
Oscillating Plate Hopper. A n Oscillating Plate Hopper improves the flow and handling of especially difficult-to-handle materials. Placed along key inside flat surfaces of a hopper, oscillating plates reduce a material's arching tendency by a factor of two when compared to typical hoppers, allowing materials to discharge without arching or ratholing through outlets half the normal size ...

In a mass flow hopper, all the material inside the hopper moves down the walls and exits. The flow is based upon a first-in, first-out principle and is uniform and reliable upon discharge. Moisture content, temperature, age, oil content, and solid levels must be regulated to ensure effective flow.

hopper design for sticky material Hoppers - Visual Encyclopedia of Chemical Engineering. General Information/Equipment Design Self dumping hoppers are designed so …
The material was wet and slightly sticky, which made it stick to the walls of the hopper, so much so that the material would accumulate and create a blockage in the hopper. Production couldn't run smoothly, requiring temporary shutdowns so employees could manually knock down the material from the walls of the hopper.

A sticky or moist dust may require steeper sided hoppers, a factory applied non-stick internal hopper coating, or both. Dry, fine bulk type dust, agglomerative dust, and hygroscopic dust may require larger than standard hopper discharge openings, and rotary airlock valves may need to be larger in size.

Modern tools for hopper design Page 4 of 8 If the material segregates, for example, the hopper may have to cope with slugs of finer and coarser material, which may be more or less cohesive respectively.
The design of the hopper should not only focus on the movement of powder in and out of the hopper, but also consider its storage in the hopper to avoid arching. A number of studies on hopper angle have led to the conclusion that the most efficient angle for flow is between 45 and 70 degrees.
