Country sales & marketing manager at sovereign logistics, florence tuei comments; as a project team, we undertook detailed preparation and planning for this delicate move, adopting global recommended standards for the transport of cement mill parts.The machinery was packed in steel frames to safely and firmly secure the equipment for transport.A total of 20 trucks were utilised for the move a combination of low-loaders and standard trucks.The parts are for a 145mtn/hour opc cement grinding plant.
The clinker extracted from the silo is taken to the cement hoppers.Via rbc.Gypsum & pozzolana also comes to the hopper building via the unloading hopper & rbc.Then the feeders provided below the hoppers regulate the flow to the cement mill.The hoppers are on load cell and they have a level indicator to stop the flow when the bin is full.
The latest professional mqx superfine ball mill, the new mill is designed with the traditional cement mill and mining and metallurgy mill different, in line with the requirements of the german ultra-fine filler grade mineral processing.Optimize the aspect ratio to prevent over-grinding, achieve the best grinding effects and grate plate grinding the end of the material, the material smooth up grinding phenomenon, the cylinder need not cooling.The hard minerals can be used without pollution iron design, lining and grinding media, alumina ceramic, quartz, silex or special materials.
The rotor rotates of our impact crusher with a high speed driven by power motor when the machine is working.When the materials get into hammer effect area, they are impacting to break with the hammer on the rotor and then threw to the impacting position to take another crushing.After that they spring back to hammer impacting area from impact wrist plate to take crushing again.China cement mill this procedure repeats itself.The materials get into 1,2,3 impact cavity from big to small to take repeated crushing.When the material is crushed to the required size, it's discharged from the outlet.The material's discharging size and shape can be changed through adjusting the gap between impact frame and rotator.
The modern plants have also taken adequate care to prevent the environmental pollution and dust nuisance to its surrounding areas.The cement mills have electro-static precipitators (esp) installed to check the dust emissions.The bag filters and glass bag houses are located at various locations to prevent dust emission and to ensure healthy and hazard-free atmosphere.
This cement mill project incorporates the stages of design and redesign of new steel components for the improvement of the grinding process, engineering, manufacturing, supply, supervision and final validation of the assembly.
(a coating is an agglomeration of the material on the lining or balls due to superficial forces and the forces generated by static electricity which happens for cement as well as limestone.This happens if fines below 2 micron are produced in the mill.It reduces the grinding efficiency of the mill.In case of cement mills, the 2nd and 3rd chamber it disturb the classification of the media in the classifying liners and reduces the attrition efficiency of the small balls due to non contact with material).
Grinding aids can give benefits of 5-15 per cent in production but need to be continuously evaluated for cost effectiveness.Unfortunately, their cost has risen more rapidly than the cost of energy in recent years and the economic balance has to be re-evaluated.The benefit of aids on cement flowability has to be considered, along with the added scope for reduction of cement clinker content with some modern additives.Correct timing on the maintenance of a first chamber cement mill lining and the successful implementation of an expert system on a cement mill both offer benefits in terms of power consumption (see case studies panel).Accurate process measurements are also key to energy saving opportunities.Air compressors are another area for attention.Often, these are multiple units operating on a cycle of on- and off-load.Replacement of one (of three) with a variable-speed type (see table 2) can provide rapid payback.Even lighting and buildings offer excellent opportunities for power savings.Table 3 shows the 40-80 per cent energy savings that can be achieved by simply replacing old lighting systems.Buildings such as the new italcementi group research and innovation centre (i.Lab) in bergamo, italy, demonstrate that good building design creates significant savings.
Having an independent audit of your cement mill can identify opportunities for productivity improvements, including increasing production or lowering energy consumption.It is common to achieve a 5-10% gain in production by following mill audit recommendations.
The cement mill is the key equipment for re-grinding cement clinker after pre-grinding by system ingredients.It plays a vital role in the cement production line and cement production process.Cement mills are mainly used in cement, silicate products, new building materials, refractory materials, glass ceramics, and other production industries.
