Safety precautions should therefore he observed, and no work should be done on the mill until it has come to a complete stop. We have now reached the point where a half ball or rod charge can be added, and the mill run for another six to eight hours, feeding approximately half the anticipated tonnage.
a batch plant component, usually located under the hot bins, in which the aggregates and asphalt cement are weighed prior to discharge into the mixing pummel wet collector an asphalt plant dust collection system utilizing water and a high pressure venturi to capture dust particles from the exhaust gas of a dryer or a drum mixer. wet collected dust cannot be returned to the mix
Static electricity in the coal mill filter could ignite coal dust and cause a fire or explosion. Safety measures preventing static electricity discharge therefore need to be in place to reduce the potential for explosions and fires. These measures include using stainless steel or .
The rate of cooling from the maximum temperature down to about 1100˚C is important, with rapid cooling giving a more reactive cement. This occurs because in this temperature range the C 3 S can decompose back into C 2 S and CaO, among other reasons. It is thus typical to blow air or spray water onto the clinker to cool it more rapidly as it exits the kiln.
The temperature is important parameter that should be controlled in cement manufacturing. Therefore, the measurements were undertaken via infrared or noncontact thermometer from the outside of the mill discharge end. Such information was used to identify if the product of the stirred mill was in acceptable temperature limits . Grinding aids

Cement bulk loader is the equipment which conveys clinker(<=50mm) in silo to clinker bulk loading ship and truck. Bottom cement clinker bulk loading equipment is mainly composed if manual bar valve, motorized fan valve, hoisting device, flexible discharge device, dust suction hoses, capacitor limit switch, electric control system etc.
1. Grate plate temperature is too high . The reasons for the high temperature of grate plate are generally as follows: (1) the amount of cooling air is insufficient to fully cool the clinker;Or because the grate bed speed is fast, the clinker cannot be cooled in time.
