As the supporting equipment of cement rotary kiln, clinker cooler also called cement cooler is a kind of heat exchange device that transfers heat from high-temperature clinker to low-temperature gas. it plays an important role in the cement clinker production process and directly affects the cement product quality. clinker leaves the cement kiln usually at more than 1200℃ and it carries the heat rotary kiln.
Dec 06, 2016 when cement clinker is ground with a specified amount of gypsum, it will produce portland cement or when ground with specified amounts of gypsum and other materials it will produce blended cements. slipstick conveyors have found their way into this process replacing buckets or belts.Cement is the glue that holds the concrete together, and is therefore critical for meeting societys needs of housing and basic infrastructure. this paper deals with a case study of a reputed cement clinker processing plant, some changes in the process has been suggested, which leads to reduction in labor cost and production cost.Clinker grinding processing clinker grinding is the stage in which the final product stage in cement production ,it is independent of each other. in this stage, the cement clinker is added with an appropriate amount of the mixed material ,it is be ground to produce finished cement.Cement clinker production line. capacity: 200 t/d-1500 t/d type: cement cli nker grinding station materials: cli nkergypsumadditives equipment: cement millcement kilnbag filter cement cli nker production line cli nker grinding station acts as an individual production line in the last period of the cement production process. in the finished product period the cement cli nker is ground rotary kiln.Composition of cement . by one of two processes - dry process or wet process. the materials are then fed through a kiln at 2,600 f to produce grayish-black pellets known as clinker.1. high efficiency. cement grinding plant has high automation level, the operating process will adopt dcs central control system for adjustment, control and alarm in master control room, then the whole plant have less operator and also increase the working efficiency.
