Bin Activator

Designed to promote flow of difficult materials from hoppers the Solitec Bin Activator comprises a Spun Steel dish onto which a domed baffle is positioned and this is supported by cross steel members with one or two out-of-balance motors inducing a vibration into the assembly. The kit is supplied complete with mounting ring (for attachment to silo by clients), inlet and outlet flexible sleeves and support clamps. To remove any vibration from being transmitted into the silo or supporting steel the complete assembly is suspended beneath the silo by suspension rods in rubber mounts.

Available in both Carbon and Stainless steel with size diameters ranging from 600mm to 3660mm, this well-tried and tested aid has proven the workhorse of Silo Discharge solutions. In some applications Bin Activators can give a level of control to discharge however we do not recommend this particular device as a control flow solution.


The Solitec Soliflo is an advanced bin discharger. Based on the proven principles of the Solitec Bin Activator. With this device the inner cone is raised and lowered automatically, creating an annular gap through which material flows. When the cone in its fully lowered position the Soliflo becomes a shut off valve.

Valve lift and vibration are induced through compressed air at 5.5 to 6 barg.

The Soliflo can be supplied both Round and Square through the size range 600mm to 2440mm and can be manufactured in Carbon steel, Stainless steel or a combination ensuring Stainless Steel parts contact with product flow. There are two types of Soliflo available to cater to most known applications:

  • Preset operating to predetermined increments. However, the flow rate from the preset Soliflo can be increased or decreased by manually adjusting internal collars, which control the lift of the cone.
  • Variable a timer in a remotely positioned control panel, which pulses the cone valve up and down thus adjusting the flow rate while the material is discharging, controls the throughput from the machine.

Screw bin discharger

Combining variable speed drives with a wide variety of configuration to suit the hopper shape and material characteristics, Solitecs Screw Bin Dischargers offer an efficient means of positive extraction and feed rate control.

Taper or straight screws in single or multi flight combinations, rectangular and circular shaped inlets and outlets. Specifications available are as varied as your needs. Our systems approach, considering all aspects of the installation, will reveal the precise Screw Bin Discharger for the application.

Ribbon bin agitator

Ribbon Bin Agitators produce a fully live bottom bin effect through a contra-flow action which continuously conditions material in store.

Standard length is normally 3 metres, in any multiple of twin-flights width. Through experiment and calculation, the ratio of height to width is chosen to produce maximum effect, generally with a fixed speed drive.

Continuous ribbon flights formed from round bar are frequently used whilst adjustable paddle blades can be specified to allow for on-site adjustments to cope with product changes.
