Discharge of agglomerated solid products:

The powder handling is one of the core capability for pharmaceutical/chemical/food industries, SteriValves experience helps processes where powders and granules tend to aggregate.

One typical example is the agglomeration of powders or granules during the transport or the stocking in the warehouse. Sometimes the product tends to form lumps that may cause problems downstream. The lumps can easily block the product flow once that the product has to be transferred through a pipe or a pneumatic conveyor.

Another example is at the outlet of a wet granulator, where undesired blocks of product can form during the processing. When transferring the product into the dryer the lump can have a moisture content that is hard to remove.

When this requirement arises, the solution usually includes the intervention of an operator that has to manually break the lumps. Sometimes through the product is very hard and the operator is forced to use tools more or less compatible with the production procedures. For example in the pharmaceutical sector, the exposure of the product to a manual action is often regarded as problematic. In other sectors the operator intervention is either unpractical or dis-economical.

In other situation the process characteristics render the intervention only occasional and a continuous surveillance of an operator just to break the lumps is a pure waste of man labor.

The ideal solution would require a system that is compact enough to be included in an existing plant and available in various sizes suitable for the existing piping dimensions.

Rotocrusher is a sanitary stainless steel lump breaker driven at speed by a direct high torque drive system (electric motor, pneumatic rotor, pneumatic actuator) that meets rigorous safety and hygiene standards while seeking the ideal fragmentation ( Nominal diameters from ND 10mm to DN 300mm)

Its output covers a flow rate ranging from 750Kg/h minimum to 3 t/h maximum. The interlaced toothed rotor design allows free flowing of the undersize material to pass through the continuously changing gaps generated by the moving shaft. Thanks to its modular, compact construction, the crusher can also be employed as a pre-breaker in conjunction with a sieve, a mill etc.

Manufactured according to cGMP it is easy to clean and it is suitable for CIP and SIP.

Field of applications:

  • Dryer: to reduce the size of the lumps that keep high humidity content.
  • Granulation process: to reduce deliberately compacted material in order to obtain an homogeneous drying.
  • Pneumatic transfer: to reduce natural agglomerations that may block the flow.
  • Thermosensitive product
  • Limited space available.

SteriValves Srl:
Thanks to its close cooperation with the leading pharmaceutical manufacturers and OEM for the past 14 years, SteriValves understands the needs and complexity of the processes and thus is able to offer targeted solutions.
