Rulmeca is specialising in the development, production and sales of belt conveyor rollers/idlers, motorized pulleys, fabricated pulleys and other components for the worldwide bulk handling industry.And we, CIEIEC is the global strategic partner of RULMECA , providing high-quality belt conveyor rollers, pulleys and other products for global cement plants.Rollers In the overall design requirements of a set of belt conveyor device, the idler will account for a large part of the investment.Choosing high-quality rollers with a guaranteed service life can ensure the good operation of the equipment andensure uninterrupted conveying operations.Facts have proved that considering the overall economic situation of todays modern conveyors, its life and efficiency largely depend on whether high-quality rollers are used, or more precisely, whether rollers made of high-quality materials are used. Rulmeca pays great attention to the requirements of the sealing system, and all roller designs have undergone strict laboratory tests to ensure the high efficiency of transportation.PulleysRulmeca has always used the most advanced technology and the highest quality materials to design and manufacture pulleys. This good practice is supplemented by a quality assurance system that has passed ISO 9001: 2008 quality system certification, which helps to produce high-quality products with reliable performance, long life, and low maintenance costs.

CIEIEC specializes in providing customers with best quality cement equipment and spare parts. Here we introduce our stepping cooler exported to our overseas customers. If you need coolers or have interests, please contact me!1.The advantages of stepping transmission wayHigh conveying efficiency, small load on the transmission system.Smooth hydraulic transmission, low failure rate.Adjustable pushing stroke to adapt to large changes in system output.The driving frequency is low, only 3～5 times per minute in normal production.2.The technical points of the stepping cooler No leakage grate structure, reducing investment cost.Modular design and manufacturing needs short installation time, having good interchangeability and strong versatility.Efficient fixed module improving the heat exchange efficiency of the inlet section.and reducing the accumulation of clinker at the entrance of the cooler.Wear-resistant sealing structure can be used both two sides, prolonging the actual service life twice.The roller support structure is safe and reliable, the maintenance and replacement are convenient.Vertical seal has good sealing effect and long service life.

As is known ,the feeding device of the cement raw material into the mill basically uses the split wheel lock air (rotary feeder), most of the use effect is not ideal, because the raw material is sticky, the phenomenon of material blocking often occurs. In response to the drawbacks of traditional unloading valves, our company has developed a new generation of QRW series of rotor-type bulk material dosing devices, which are accurate in measurement, wide in adjustment range, compact and fully enclosed, high temperature resistance, long service life, low failure rate , and low maintenance cost. It is widely used in building materials, metallurgy and other fields. The feeding system of the QRW flange special mill is developed by our company to slove the disadvantages of the traditional vertical mill feeding lock valve, such as easy accumulation, blocking, and air leakage. The feeding device has unique anti-jamming technology, good at air locking and material drying . The equipment has simple structure, small maintenance workload and low power consumption.The benefits of this equipment is listed as below:1) The equipment installation need small space, the modification is simple and need short short time to finish;2) Effectively prevent equipment sticking and jamming, improve system operation rate, effectively reduce sticking and hardening of viscous materials, and reduce cleaning work;3) If it stops under extreme conditions, it can start normally after reverse rotation, reducing the impact time of the accident;4) Reduce the number of process failures and shutdowns, increase the continuous operation time of the raw meal system, and reduce power consumption;5) Reduce breakdown damage and operation wear, reduce maintenance workload and costs;6) Good air lock firstly can improve the powder separation ability and separation effect of the fine powder in the mill, thereby increasing the output of the system by 5-10% per hour, and further reducing the power consumption of the grinding; Secondly , it can improve the drying capacity of the system, improve the adaptability to the water entering the mill, alleviate the decline in output due to material moisture, and reduce the impact on the full-load production of the firing system; Thirdly ,it can effectively reduce the operating load of the vertical mill circulating fan and the exhaust fan of the kiln tail, and the electricity saving per ton of raw material can reach 0.3 ~ 3kwh.7) Stable continuous operation is conducive to the stability of raw material quality, which in turn improves the output quality of the firing system and reduces coal and electricity consumption;8) The transformation benefit is significant, and the investment recovery period is less than half a year.

CIEIEC specializes in providing customers with best quality cement equipment and spare parts. Here I would like to introduce the technical advantages of ZTA (Zirconia Toughened Alumina) cermet composite grinding roller. 1. Long service lifeThe Vickers hardness of ordinary high chromium cast iron is about 700HV, and the hardness of ZTA (Zirconia Toughened Alumina) ceramics can reach 2100HV. The service life of ZTA cermet composite grinding roller with composite casting technology is 2-3 times of ordinary high chromium cast iron grinding roller. 2. Higher mill working efficiencyThe ZTA cermet composite roller sleeve and liner have a special honeycomb ceramic grinding layer design, which increases the friction coefficient between the material ,the original smooth appearance of the roller sleeve and the liner can be better maintained during using life , so that the grinding roller and the liner can better fit and run. The mill has higher working efficiency, which can increase the grinding efficiency by more than 15%.3. Energy savingAccording to user feedback, ZTA cermet composite roller sleeves reduce the unit power consumption of the mill by 1kWh/Ton compared with high chromium cast iron roller sleeves. This is due to the special negative pressure casting infiltration composite casting process of ZTA cermet composites. 4. Reduce the mill maintenance frequency and reduce equipment maintenance costThanks to the great improvement of wear-resistance of the ZTA cermet composite roller sleeve and liner working surface, the number of mill downtime is greatly reduced, and the synchronous maintenance of the mill is realized once every two years, greatly reducing the maintenance workload and equipment maintenance cost.
