Estromat 850

Mixer and Conveyor for Low Cement (LC) and Ultra Low Cement (ULC)

Casting Materials on the Basis of Bauxite, Corundum and Spinel, with SiC- and C-additives as well.

Batches up to 1,5 tons

ESTROMAT 850 with hose-outrigger


The ESTROMAT 850 has been especially developed as pressure vessel machine for the processing of refractory materials for the supply of casting ladles, blast furnace troughs and runners etc.

The big volume of approximately 850 l as against the so far used pressure vessels of 260 l as well as 600 l volume is very suitable for economical and reliable processing of pre-mixed refractory masses in Big-Bags of 1,5t.
