Whatever the discharge problem,Mucon Discharge Aids offer both an efficent and effictive solution.

The easy to install solution to discharge problem:

shakes the contents-not the bin

The custom made intemally mounted screens are specially designed to transmit vibration directly into the product preventing material bridging,rat holing or segregating during discharge.Available in carbon or stainless steel and in Mini.Standard or Super configuration,promo-Flow is the silo discharge system which‘ SHAKES THE CONTENTS-NOT THE BIN’.

The problem

There are many reasons for powdered or granular materials not discharging from hoppers or silos as soon as possible.

Rat holing

Segregation

Ideal for existing silos:

Promo-Flow discharge wywtems are easily fitted retrospectively to existing silos and hoppers and can be designed to fit most shapes and sizes.

The Solution

The installation of a Promo-Flow discharge system will promote the folw of any product which is nomorally capable of flow,but which needs occasional or frequent help to get started or to keep it moving.

How Does it Work?

Promo-Flow dischage systems introduce vibration directly into the product keeping it “alive”and thus reducing the strength of any bonding or locking of the particies,which may result in a flow problem.

Robust vicrators mounted extemally activate vibrating screens mounted on the inside of the silo walls,at the points where flow problems occour.

Screens:

There are 52 standard sizes and shapes with an infinite number of variations.Screens can be either flat or curved to suit hopper contours and there are two types aviailable:mesh and rib cage.Both screen types can be made from either carbon or stainless steel.Optional finishes including plastic and epoxy coating are also available.

Rib Cage Screens:

These are high pressure water cut from either carbon or stainless steel plate with variable width ribs to prevent resonance.Rib cage screens are used for large particles and fibrous materials.

Mesh screens:

These are manufactured from expanded metal sheet and are stiffened by a metal framework.Mesh screens should be selected for all applications involving powder and granular materials up to about 20mm in diameter.

Triangular- —Suitable for most cylindrical hoppers when suitably curved to match the contour of the conical section.Also suitable for the converging section of rectangular hoppers,in which case the screens are flat.

Control Systems:

Promo-Flow discharge systems should only be operated when the product is able to flow out lf the silo at a rate greater than the feed rate induced by the vibrating screens.Some products only require an initial 'nudge'after standing for periods of time.Other products may require some aid to promote their flow,say after a spell of damp weather.On the other hand there are many products/hopper situations,which require continuous or frequent agitation of the products to keep it moving.

Accordingly three basic control packages are offered:

• Manual on/off
• Load dependent sensor
• Programmed control

The Range:

Mini Promo-Flow discharge systems are designed to fit the smallest of hoppers,bins and feed chutes etc.They are ideal for fitting into hoppers above tableting presses,metering feeders,extruders etc.

Standard Promo-Flow discharge systems are a range of general purpose models for a multiplicity of applications associated with average sized storage vessels and silos.

Super Promo-Flow discharge systems are designed for the biggest of silos and to cope with the most arduous of applications where the bulk density of the silo contents is high.The rubber isolation mounts are considerably more resilient to accommodate the increased loads.

Diamond- —Suitable for applications involving high bulk density materials where large areas of action are required,but where the loading on a triangular or rectangular screen would be too high.They can be flat or contoured as required.

Rectangular- —Suitable for use in chutes or flat sided bunkers.In extreme cases of 'bridging'they can be used on the parallel section of hoppers and can be either foat or contoured.

The number of screens required is determined by ensuring that the loading on the screen does not exceed the maximum rating for the appropriate screen size.
