Liming Heavy Industry have many pulverizers and crushers. The Liming Coal Pulverizers are speciﬁ cally designed for increased operating cycles and lower maintenance costs. Liming Sales Team supports all replacement parts and upgrades to suit customer individual needs. Replacement Parts:
• Airports Upper & Lower
• Eccentric Hubs
• Oil Seals
• Coal Shields
• Roller Hubs
Coal pulverize service fields : With 25 years of experiences, our services include mill inspections and performance evaluations including off-site grinding roller rebuild and refurbishment. As part of our quality-focused commitment to continuously improve coal pulverizer operability and maintainability, several major design upgrades have been made available for both the Liming pulverizers. These customized upgrades have assisted many of our customers in dramatically reducing maintenance budgets while improving proﬁ tability throughout the equipment’s long service life.
Dynamic Pressurized Rotating Classiﬁer The rotating classiﬁer offers coal ﬂow and ﬁneness control using variable speed drive. This new design will greatly improve output and increase the efﬁ ciency with added ﬂ exibility to process varying types of fuel in existing mills.
Rotating Airport Design: Our latest improvement in Liming air-coal ﬂow geometry reduces wear on the airport surfaces. The rotation of the ports reduces housing wear by spreading the wear more evenly over the entire periphery of the pulverizer. The 3-sided airport design results in a self-cleaning action of the gap area.
These new airports are two-piece rotating airports. The lower airport segment will be cast iron while the higher wear upper airport will be made of cast chrome-moly abrasion resistant white iron. The porting will be designed for the current ﬂow conditions operated at the plant. This design extends the total wear life and as a result, reducing required maintenance hours and parts replacement cycles.
High-Chrome Rollers and Grinding: Table Segments Rollers and Grinding Table Segments have become our standard offering and have dramatically increased durations between required change outs.
Next Generation Ceramic Tires and Segments: This new technology combining Ceramics and Iron brings a higher wear resistance and durability over High-Chrome Roller. Expected wear life may be doubled for the same size roller. Ceramic is imbedded in the high wear surfaces in order to maintain an even proﬁ le longer and reduce roller vibration during operation. As a result, ceramic rollers will decrease wear of internal components and with it maintenance cycles.
