At DustMASTER, we offer a full line of refractory mixers that are designed to hold up to the most extreme industrial environments. Available refractory mixers include our Prashak horizontal shaft paddle mixers, our flagship Turbin Mixer XL series as well as planetary mixers with motors ranging from 7.5 hp up to 100 hp. All are up to the challenge of mixing dry, semi-dry and low-moisture refractory castable materials. These batch style mixers are available with capacities from 3 to 81 cubic feet, with a maximum batch weight of 12,000 lbs. All components from the paddles and mixing shafts to the V-belt drive system are constructed of rugged materials and designed for maximum durability. The interior is lined with abrasion resistant steel and cast Ni-Hard to increase equipment life.
