Path: Micronisers / SuperJet -Bottom discharge / Kompak series

SuperJet microniser Kompak-1 is the typical machine for laboratory and R&D applications.
In production since 1988, this machine was repeatedly improved in terms of versatility and compactness.
It is offered with two construction models: bench-top ( K1BPT), and self-standing ( K1BP side photo).

The modular design allows customization and interchangeability of different components such as the product feeding system, the microniser, the product collecting bin and a wide choice of ( optional) process controls.

All versions and construction models feature the following components:

  • SuperJet microniser with direct collection of the product from the grinding chamber, without risk of fiber contamination. It has a nozzle ring with optimized grinding angles, a horizontal venturi feeding system that avoids metal contamination and built-in, static classifying system that assures very narrow, particle size distribution
  • Twin-shaft feeder, volumetric type, with concave-profile, self-cleaning, screws, able to break the agglomerates and to assure an accurate feeding of poor flowing products, for the whole batch.
    The feedrate is controlled by a stepless, mechanical, speed variator.
  • High-efficiency, dust separator combining inertial and static effects. It is equipped with a membrane filter cartridge, reverse-pulse, automatic cleaning and final, safety HEPA that exhausts breathing air quality to the atmosphere.
  • Standard controls, integrated in the front panel, include process pressure regulators, pressure gages and differential gages to monitor the filters.
  • Full stainless steel construction, bright finish, with all product contact parts made of AISI316L, hand polished to pharmaceutical, mirror finish 360-400 grit, Ra 0.15-0.25µm

With this modular design, all versions can be equipped with the following options:

  • automatic controls and sound alarm that monitor continuously the factory air supply and the process lines and stop the operation in case of failure
  • high-precision, electronic pressure controls that monitor the microniser with proportional pressure regulators, specifically dimentioned for very quick response and steady operation
  • synoptic and LCD-alarm display with fault messages in plain english, to signal pressure drops on the microniser lines and across the filters
  • electronic motor controller allowing stepless regulation of feed speeds across the specified range and features current limiting to prevent overloading
  • sterilizing air filters for each process line, USDA-approved and certified
  • batch validation equipment including 4-20mA loop signals from pressure transducers and process recorder to document each event and alarm.
  • vacuum compensation system that avoids environment contamination in case of blow-backs.
  • replaceable internal linings include PTFE and hard-metal alloys, etc.

All SuperJet Micronisers can be customized according to the purchase and the product specification.
