Mucon Promoflow Dischargers

The Mucon Promoflow discharger is one of the most effective hopper and silo dischargers available.

How It Works

How It Works

Discharge problemsThe Problem

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

The Solution

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

How Does It Work?

Discharge-Aids-silo

The Mucon Promoflow discharge system introduces vibration directly into the product keeping it “alive” and thus reducing the strength of any bonding or locking of the particles, which may result in a flow problem.

Robust vibrators mounted externally activate vibrating screens mounted on the inside of the silo walls, at the point where flow problems occur.

Rubber isolation mounts attach the Promoflow discharge system to the silo preventing leakage through the mounting holes. The whole unit is allowed to vibrate while imparting little or no vibration to the silo itself.

Ideal For Existing Silos…

Promoflow discharge systems are easily fitted retrospectively to existing silos and hoppers and can be designed to fit most shapes and sizes.

Applications

Applications

Mucon Promoflow Discharges are used in all Powder Handling Industries and Applications where difficult flow powders and other solid materials do not easily discharge form silos and bins.

Range & Design Options

Range and Design Options

The Range

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

Super Promoflow 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.

Control Systems

Promo-Flow discharge systems should only be operated when the product is able to flow out of 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:

  1. Manual on/off
  2. Load dependent sensor
  3. Programmed control

Rib and Mesh ScreensScreens

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 available: 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.

PromoflowscreenshapesTriangular – 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.

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 flat or contoured.
