Knauf PFT - HM 24 screw mixer

HM 24 The clever mixer for bagged and silo goods

The horizontal PFT screw mixers of the HM series - also called mortar mixers - continuously and fully automatically mix all ready-mix dry mortars based on cement (e.g. masonry mortar, jointing mortar, levelling compounds, adhesive/reinforcing mortar) to produce an application-ready material. All-round qualities, easy to work with and maintenance-friendly belt drive characterise the machine. Depending on the series version, screw mixers can be used either with bagged goods only, or optionally with bagged or silo goods or only with silo goods. The HM 24 400V is the all-rounder among PFT screw mixers. Not only can the machine be used to process any lime and cement-based ready-mix dry mortar with a grain size of up to 4 mm; thanks to PFT modular technology, the machine is set up for the desired filling in no time at all, be it bagged goods, silo/container or pneumatic filling by means of an injection hood and PFT SILOMAT conveying system.
