Ceramic Grinding Roller
For Vertical Roller Mill
www.qimingcasting.com
Ceramic Grinding Roller
Ceramic grinding rollers are made of wear-resistant industrial ceramic
particles (inlay) and high-chromium cast iron (matrix). It's a new type
of composite wear-resistant grinding roller produced through one-go
pouring & casting technology.
Matrix:High Chrome Cast Iron
Thickness of Embedded Ceramic:40mm-60mm

Consumption
Ceramic grinding rollers are considered as the best
wear-resistant solutions for vertical mills, and now
are widely used in cement, metallurgy, electric power,
construction, mining and other industries.
Longer Service Life
The service life of the grinding roller depends on the wear condition of its roller surface. The higher the
hardness of its surface, the greater its wear performance, hence a longer service life. It all depends on what
material to choose.
Ceramic grinding roller helps reduce:
Higher Production Yield
The surface of traditional grinding roller is getting smoother after frequent grinding between the roller
and the grinding material. Its friction coefficient, grabbing ability and its yield pervertical roller mill will
then all be noticeably reduced.

See what ceramic grinding roller will bring to you. Specially designed honeycomb structure that
significantly increases the bite force and grinding efficiency of the grinding material, increasing the yield
of the mill (per unit) by 5-10%.
The material of traditional grinding roller is usually high chromium cast iron or hardfacing. Due to the
characteristics of the material, the hardness is generally around HBW 650. Ceramic grinding rollers are
embedded with high-hardness, industrial wear-resistant ceramics in the wear area of traditional high-
chromium cast iron rollers. Its hardness can reach HV 2100, increasing the wear performance in the wear
areas and significantly extending the service life of the grinding roller.

The specially designed honeycomb structure enables the grinding curve of the grinding roller and lining
plate to maintain a sufficient grinding area, reducing the mills power consumption by about 7%.
