Lubrication system is in the key part to reduce mechanical wear and tear, including the ball mill. Generally, you should replace all the old lubricating oil and clean the machine thoroughly after the mill was put into work as long as one month. After that you should change the lubricating oil about every six months for each time.
The amount of water to be. sprayed per hour is calculated based on the heat balance calculations which comes to be around. 2100 lit/hr. Water spray system is designed to control the cement mill temperature by spraying. water at the inlet and outlet of the cement mill. The system designed works on the temperature.

API Spec 10A (2019) has required standard water to cement ratio for neat cement systems, Table 2. The simplest way to achieve lowdensity slurries is by increasing the water content, however, such systems have stability issues, poor mechanical properties, and longer set times ( Kulakofsky et al., 2005c ; Sarmah et al., 2016 ).

Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set. Water spray is controlled with mill outlet gas or material temperature. A hardware interlock is recommended with mill main drive to avoid accidental spray in mill.
A lime/limestone spray dryer system injects a slurry of lime or limestone into the conditioning tower of the preheater. The spray dryer SO2 removal efficiency is between 5090%. A few wet scrubber systems have been placed after the particulate matter control device (PMCD) with all or a portion of the exit gases passing through them.
For example, if the fresh material is very hot, water injection, clinker >120°C, a water injection system is used at the mill inlet. In most cases, from a process engineering point of view, a water injection system in the second grinding chamber makes sense to control the steadily increasing heat, generated by grinding.

The invention discloses a water spraying device for a cement grinding mill, and relates to the technical field of cement device manufacturing. The water spraying device comprises a regulating water valve, an air compressor and a PLC control system. A tap water inlet pipe is connected with an electromagnetic valve controlled by the PLC control system.
The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110ºC 120ºC, cooling to below 80ºC is necessary to avoid this reaction.
Cement Manufacturing. In harsh cement manufacturing environments, the right nozzles, spray lances and highpressure spray guns can make all the difference on the bottom line. That's why cement plants depend on spray technology and expertise from Spraying Systems Co. We've worked with cement plants of all sizes all over the world, helping ...
