400L concrete mixer machine is an industrial-grade batch mixer designed for small to medium construction projects. It typically features a drum capacity of 400 litres, allowing it to process roughly half to one full 50kg bag of cement per single batch.Batch Capacities: Unmixed material volume is around 310L, yielding roughly 220L to 260L of wet, mixed concrete per cycle.Hourly Production: Average output ranges from 3 to 4.65 m3/h depending on labor efficiency and model type.Drum Speed: Rotates at approximately 30 RPM to ensure standard homogeneous blending.Mobility: Generally built with a heavy-duty reinforced frame mounted on 4 pneumatic tyres or towable wheels for easy job site movement.
