Description 

MATERIAL: Aluminum oxide in acidic solution of stabilizers and catalysts including Cerium and Platinum.

PROBLEM:

Scale-up to 3,000 gallon batch required 10 foot long drive shaft on 3600 RPM rotor/stator mixer. Required shaft steady bearing experienced abrasive wear in too short an interval between required maintenance.

RESULTS:

Vigorous mixing and re-dispersion of alumina slurry with stabilizers and active components of catalysts coating obtained. Meantime between required maintenance increased to 2x per year on 16 hour day/five day week basis.

AB MIXER:

Bottom-entering Model T-5-B Reversible Homogenizer with abrasion resistant 17-4 PH rotor and double mechanical seal with labyrinth and air purge.

EQUIPMENT
REPLACED:

Top entering high shear mixers.

BENEFITS:

80% of annual downtime eliminated, maintenance labor reduced by 75%, replacement parts costs reduced by 2/3 because sturdy and short drive shaft on Model T-5-B does not require a steady bearing in the rotor housing.
