This standard prescribes the requirements for pan type concrete mixers, covering their nominal sizes, capacities, material specifications, design features, and power units. It ensures the equipment is standardized for efficient and uniform mixing of concrete, particularly for stiff or semi-dry mixes used in precast industries.
Specifies requirements for pan type concrete mixers used for construction purposes.

Practical Notes
Pan mixers are highly recommended for zero-slump or semi-dry concrete mixtures where traditional drum mixers struggle.
Regular inspection of the gap between the mixing blades and the pan base is crucial; excessive clearance leads to poor mixing, while too little clearance causes aggregate crushing and rapid wear.
Ensure proper calibration of the water dispensing unit attached to or used with the pan mixer to maintain exact water-cement ratios.
