Liner

CIC’s equipment includes leading standardized heavy equipment and machinery products and related heavy machinery services, which can be sold directly to end customers, business partners, and EPC projects. As a professional heavy equipment companies, CIC serves multiple roles, such as, cement machinery suppliers, mining machinery manufacturers, grinding mill manufacturer, rotary kiln manufacturer, rotary dryer manufacturer, sludge dryer manufacturer and so on.

Liner is to protect the shell from direct impact and friction of grinding mill parts and is also used to modulate the motion of grinding material. It could improve grinding efficiency and productivity, as well as reduce wear resistant liner. CIC's mill liner spread all over the world along with CITIC's mills. For years, CIC's manufacturing ability is not only embodied in the supplying of mill  liners for certain mills with the detailed specification but also especially in the on-site mapping, model changing and efficiency improvement.

Introduction of Liner

CIC is a leading comprehensive mill liner supplier in China. For years, CIC's mill liner spread to all over the world along with CITIC's mills. With the property of leading technology and unique expertise, lower cost and higher availability, CIC's liner has won high approval from the customers.

CIC's manufacturing ability is not only embodied in the supplying of mill liners for certain mills with detailed specifications but also, and especially in the on-site mapping, model changing and efficiency improvement. CIC has the ability to offer solutions for all kinds of mills, such as cement mill, mine mill, ball mill liner, rod mill liners, ag mill liners, SAG mill, etc.

With several decades of development, CIC has become the Manufacturing Base of Liner of Semi-autogenous mills.

• Optimizing Manufacturing Process, Guarantee Liner Quality

Our high-quality liners manufactured by the advanced process have covered the wide marketing of semi-autogenous mills.

• Optimizing Liner Design, Eliminating Break of Liner

A main working function of the liner is to lift the milling ball to a reasonable height, then fall along with the right rack and smash against the material enrichment area at the bottom of the mill in order to crush the material effectively. So it is greatly important to reasonable optimizing the liner design and correct guiding the milling ball running track in order that guarantees the optimized operation condition in the mill and effectively protects the shell liner of the semi-autogenous mill, meanwhile, can eliminate liner break, prolong the service life and decrease effectively unit wear of liners and milling ball, and improve the hour production per machine.

• Focusing on Detailed Operating Condition, Improving Users' Benefits Optimizing

The liner design based on the wear forms of liners in different operating conditions maximally decreases the crashing function of the liners and effectively decreases the weight of scrap liners. Improving the shape of liners can effectively improve the relative motion state between milling balls and liners, then decrease liner wear by material and milling balls and prolong the liner service life while reducing the users' production cost.

Star Products

With better performance and property than the common ball mill liner replacement, low carbon martensite alloy steel and chromium-molybdenum steel mill liners have a unique chemical composition and super mechanical properties which won a great reputation from the final users.

Design Experience in Liner

In order to optimize material, structure and techniques, as well as to extend liner life, improve efficiency and reduce the cost, we will use the simulation casting software (MAGMA, Intecast CAE), discrete element method (DEM), finite element method (ANSYS) and 3D CAD (Solid Works) to carry out model selection and design.
