This M-40 SL is a used mixer and blender — sometimes referred to as a sigma mixer or dough mixer — designed to combine, knead, and homogenise viscous, dense, or heavy materials using a pair of intermeshing Z-shaped blades. Machines of this type are widely used across the food processing, rubber, plastics, adhesives, and chemical industries wherever thorough, uniform mixing of thick or paste-like substances is required.
This unit dates from 1990 and is located in Barneveld, Netherlands. It carries serial number 3714 and is constructed from mild steel throughout. The total vessel capacity is 400 litres, with a useful working capacity of 250 litres, and the trough measures 845 × 700 mm. The machine is fitted with a single Z-blade assembly and is driven by a 1.5 kW motor rated at 220–240/380–415 volts in an explosion-proof (Ex) configuration, which makes it suitable for environments where flammable materials or vapours may be present.
The blades operate at two arm speeds of approximately 15.5 and 20.0 rpm, and the unit is single-geared. Tilting of the trough is achieved hydraulically, and the machine is supplied complete with its hydraulic unit. A cover is fitted over the trough, and the vessel is equipped with a jacket rated for a working pressure of 4 bar, allowing temperature control of the batch through heating or cooling media. The main vessel operates at 0 bar. The specification notes that vacuum operation is also possible, broadening the range of processes and materials this machine can accommodate.
The overall footprint is 2.2 × 2.8 metres with a total height of 1.8 metres, giving a clear indication of the floor space and clearance required for installation.
