HR 990 is made of selected high-quality raw materials, which is high density, high loading at high temperature and long service life.

Applicable field: large-size porcelain, tableware, polishing glazed tiles, water permeable brick, super-wide body kiln and so on.

We adopt Germany prescription with imported materials, will vacuum refining 3 times to make uniform and plasticity mud, air dry three times until qualified for moisture inspection. We pick top-grade body using slurry extrusion molding method, hanging sintering in the kiln which is 1600℃ more than 30 hours. We strictly control every production detail, prevent any pollution in the production line, and using CNC machining to improve accuracy.

We are committed to providing high-quality alumina ceramic roller which is with high-temperature strength, great thermal shock resistance, and the lowest straightness. Offering long life-service for your kiln, it would be the best choice of polishing glazed tile, rustic tile, large size porcelain tile, thick tiles, and wide-body kiln.
