Vibratory Feeder - with V-shaped channel

LABORETTE 24

OVERVIEW

Reliable automatic feeding

The Vibratory Feeder LABORETTE 24 is ideal for automatic, uniform feeding of free-flowing materials into sample dividers, mills or mixers in your laboratory. The vibration, which is controlled by a microprocessor, conveys the sample material out of the funnel over the V-shaped stainless steel channel into the respective equipment. The flow rate can be individually adjusted; the vibration amplitude is precisely controlled – for absolute uniform feed of even smallest quantities. Safe and reliable.
The Vibratory Feeder LABORETTE with a V-shaped feeder channel made of stainless steel is ideal for a narrow directed material feed between 1 g/min and 1,500 g/min.

 

WORKING PRINCIPLE

Through vibration of a channel of stainless steel, free-flowing material is conveyed out of a funnel and to the open end of the channel in a uniform stream. The rate of flow can be controlled individually with a separate control device by modifying the vibration amplitude of the channel. Control of the vibration amplitude is performed by a microprocessor-controlled control unit with which even the smallest quantities of material can be conveyed with absolute uniformity.

FEATURES
  • As a standard, with polished stainless steel channel and funnel, PTFE-coating on request
  • Precisely controlled by microprocessor control with interface
  • Extensive choice of flow rates for smallest and largest quantities
  • Simple to clean due to easily removable components
  • Small footprint
  • Separate control unit for simple regulation of sample flow
  • Material bed height is variable, can be regulated by adjusting the funnel height according to the material
  • V-shaped and U-shaped channels easy to interchange
  • Maintenance-free electromagnetic drive and components
  • Recyclable, compact cast housing
  • Low energy consumption, only 0.1 kW drive power
