Pilot Scale Batch Mixers
Pilot Scale Batch Mixers
This series of mixers are designed for small scale production in pilot plants, research institutions, hospital pharmacies, etc. Light and easily operated, AX series models have a capacity of up to 50 liters.
The Silverson multifunctional AX5 laboratory mixer features a range of instrumentation invaluable where process validation and reproducibility is required and provides an accurate and easy means of forecasting the performance of larger Silverson machines under full-scale working conditions.
The AX5 is suitable for the widest range of applications - mixing, emulsifying homogenizing, disintegrating, dissolving - with an efficiency and flexibility unmatched by other machines.
Features:
- Powerful 1HP (0.75 kW) motor
- Touch pad controls
- Electric rise & fall bench stand
- Variable speed. Nominal maximum speed 6000 rpm
- Compatible with the DataLogger system
- Nominal capacity of up to 50 litres
How It Works
The advantages of Silverson’s high shear rotor/stator batch mixer over simple conventional stirrers or agitators stem from the multistage mixing/shearing action as materials are drawn through the specially designed Silverson workhead - the heart of every machine.
Stage 1
The high-speed rotation of the rotor blades within the precision-machined mixing workhead exerts a powerful suction, drawing liquid and solid materials upwards from the bottom of the vessel and into the center of the workhead.
Stage 2
Centrifugal force then drives materials towards the periphery of the workhead where they are subjected to a milling action in the precision-machined clearance between the ends of the rotor blades and the inner wall of the stator.
Stage 3
This is followed by intense hydraulic shear as the materials are forced, at high velocity, out through the perforations in the stator and circulated into the main body of the mix.
Stage 4
The materials expelled from the head are projected radially at high speed towards the sides of the mixing vessel. At the same time, fresh material is continually drawn into the workhead maintaining the mixing cycle. The effect of the horizontal (radial) expulsion and suction into the head is to set up a circulation pattern that minimizes aeration caused by the disturbance of the liquid’s surface.
