Welcome: Beijing Better Carbon Excelsior
Graphite block (sheet) seal is a contact sealing device where the main sealing material is graphite block (sheet). At present, it is widely used in cement, mining and other rotary kiln in the kiln head, kiln tail and single cylinder cooler feeding device, which can be divided into two kinds of its structure, namely spring graphite block seal and heavy vertical graphite block seal.
The rotary kiln graphite sealing block(sheet) produced by BETTER CARBON has the characteristics of high temperature resistance, good thermal conductivity, high melting purity, strong corrosion resistance, and long service life. Our strong graphite resources and technical strength ensure that we can provide customers with a variety of products and services ranging from simple processing to highly difficult CNC processing.
For example, the cement rotary kiln is a thermal equipment operated under the state of negative pressure. The quality of the sealing state at both ends is directly related to the yield, quality and energy consumption of cement clinker. Moreover, due to the high surface temperature of the kiln body and the harsh working conditions, the maximum contact stress is> 300MPa, which is difficult to adapt to general lubricants. Tiny Carbon graphite block has stable high temperature resistance and good self-lubrication performance, which can better meet the requirements of rotary kiln seal.
