Dear Analysts, We are facing an issue on our cement plant. It's raw mill main drive motor of 4300kw. On no load condition, vibration is normal but as the feed come, vibration reaches to 4-6 mm/sec (fluctuating between 4 and 6) and whole vibration is on 85Hz (which is natural frequency of end shield bearing housing as told by manufacturer). According to manufacturer, this frequency is …
Rotary kiln equipment can be used for calcining many varieties of material v and has a wide application. Usually when encountering some waste which is difficult to deal with, it must strictly process to ensure safety with no pollution. At present, we find that the cement kiln can reduce the dangers of hazardous materials or pollution, and cement kiln is magical drying equipment.
Cement production in the world is currently about 1.6 billion ton per year. About 2% of the electricity produced in the whole world is used during the grinding process of raw materials .While total electrical energy consumption for cement production is about 100 kWh/ton of cement, roughly two thirds are used for particle size reduction .About 65% of the total electrical energy used in a cement ...
In cement production process, about 26% of the total electrical power is used in grinding the raw materials. During grinding process, the energy obtained from the rotary burner is consumed. In this study, the first and second law analysis of a raw mill is performed and certain measures are implemented in an existing raw mill in a cement factory ...
high vibration of vertical mill for raw material. Hi everyone! We have a problem with our rawmill (type: Vertical mill of Pfeiffer, capacity: 320 T/h) is that: Rawmill is difficult for start because of high vibration, sometime after starting ~ 8 - 10 hours the rawmill suddenly vibrated very high and stopped. the liner of table is worn quite much and same with roller tyres.
The vibration on the unit regularly The literature survey indicates that studies on industrial scale raw mill in cement industry under real working conditions are limited in number In this study the raw mill of a cement plant is considered and its specific energy consumption is investigated Effects of ball charge.

Raw mill is generally called cement raw mill, raw mill in cement plant, it refers to a common type of cement equipment in the cement plant.In the cement manufacturing process, raw mill in cement plant grind cement raw materials into the raw mix, and the raw mix is sent to the cement kiln to make cement clinker, next, clinker and other admixtures will be ground into finished cement by cement mill.
A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...
