Wirtz – OxMaster Paste Mixers – OxMaster 500 KG Mixer

The OxMaster Paste Mixing System is a 550 KG lead paste mixing system that gives guaranteed high capacity, efficiency, and provides an environmentally safe working place for operators.

OxMaster’s mixers were the first designed specifically for the battery industry. Our mixers have been installed for over 30 years and many are still in service. OxMaster’s design starts with a single piece tub weldment and a crosshead design that provides its users with low maintenance, long term corrosion resistance, and high shear mixing. From this basis, numerous improvements in mechanical durability, electrical and controls features, and process capabilities have been made. OxMaster’s experience and design flexibility make it the most reliable and economical mixer available today.

The mixing tub is a unique pan type / high shear system that uses a cross-head design that ensures the mixing blades strike a fresh paste surface at 120 times per minute. Batch sizes can range from 200 Kg (440 lbs) to 500 Kg (1,100 lbs) of dry oxide per batch with typical cycle times ranging between 10 and 25 minutes depending on chemistry, climate, mixing process, and cooling features.

Mixer configurations can be tailored for high automation or batch to batch consistency based on the variety of features that we offer as options. Our systems feature no compromises in structural and stainless steel construction. They are strong and reliable with the lowest maintenance and longest life of any mixer today. Once you decide upon an OxMaster mixer you can plan to use if for a lifetime.

Highest Quality Paste

Paste by measurement is defined by cube weights and penetration readings. Paste made by an OxMaster mixer is characterized by the start of the crystalline formation in the paste known as the “crunch” you feel when you take a handful of prepared paste and squeeze it in your hands. Acid addition, sulfation and not over mixing are the keys to the best paste.

*These are very general specification and will change based on the exact configuration of the system that is ordered.
