Product Details

The Mucon PromoFlow is the answer to the problem of non-discharging product from bins, silos or IBC'S.


The custom made internally 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, PromoFlow 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. Material converging towards the outlet of a hopper builds up forces within itself, which can cause it to become self-supporting.


Particle size, particle shape, material bulk density, moisture content and hopper design are some of the factors which determine whether or not a product will bridge, rat-hole or segregate upon discharge.


The Solution - To overcome the problem of poor material flow, the installation of a Promo-Flow 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? - Promo-Flow discharge systems induce vibration directly into stored 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 points where flow problems occur. The vibrators are attached to mounting brackets directly connected to the internal screens by large bolts, which pass through the walls of the silo.


Rubber isolation mounts attach the Promo-Flow discharge system to the silo, preventing leakage through the mounting holes. The whole unit is allowed to vibrate whilst imparting little or no vibration to the silo itself.


Sizes Standard and Super

  • 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.


  • Transmits vibration directly into the product, Shakes the contents, not the bin
  • Imparts little vibration to the silo itself


  • Easy to install
  • Whisper quiet operation
  • Can be fitted in any location within a storage vessel where a flow problem exists
  • Can be easily fitted to existing hoppers
  • Low air consumption
  • Well proven design with many satisfied users in a wide variety of applications
