The machinery platform
Ample space is provided on the machinery platform for access to the mixer
inlets and other components, so that cleaning is an easy matter.
Rotary distributor
The individual aggregate silo compartments are filled from a rotary distribu-
tor or, on larger installations, a rotary distributor belt.
Weighing systems
The cement, water, aggregate and admixture weighers all supply precise
measured values to the control system. All weigher systems are suitable for
calibration. Rapid, accurate batching is essential if mix formulae are to be
complied with despite high output rates.
Up to six cement-screw inlets can be accommodated at a single cement
weigher. The aggregate weigher has protective rubber mats to prevent wear.
Other forms of material delivery
Additional batching devices can be used to supply steel, synthetic fibers,
micro-silicate slurry (compacted or loose) or dye to the mix.
