cement manufacturing process flow chart
Generally speaking, the cement industry production is Portland cement. Portland cement is a kind of delicate, usually gray powder, which consists of calcium (from limestone), silicate, aluminate and ferrite(clay).
Mentioned cement production people will say "two grinding burn",that means cement production process mainly includes three stages: raw meal preparation, clinker burning and cement grinding. The cement manufacturing process flow chart is shown as follows:
In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about 1.3 tons of limestone, more than 80% of raw material is limestone. Our company has a variety of limestone crushers for your choice, such as jaw crusher, impact crusher, cone crusher, VSI crusher and hammer crusher,etc.
According to availability and chemical composition, additional components could be added towards the raw mix. These are referred to as "Secondary" raw supplies.In the cement manufacturing process, each producing 1 tons of cement grinding material at least 3 tons (including fuel, clinker, gypsum, mixture and all kinds of raw materials).
The stability of raw material composition is the premise of clinker burning system. Raw meal homogenizing system stabilizes the raw ingredients into the cellar of the final control action. Clinker burning The rotary kiln is a cylindrical steel vessel, that is inclined for the horizontal at 2.5% to 4.5%. The kiln slowly rotates at 0.5 4.5 revolutions per minute to allow the material to tumble by means of the kiln to ensure adequate residence time in the kiln to accomplish the needed thermal conversion processes. The finely ground coal is fed for the firing end of the kiln exactly where it really is burned to create a gas temperature of around 2,000C. A preheater consists of several stages contained in a tall preheater tower, which utilizes the heat produced by the flame at the firing end from the kiln to preheat the raw supplies as they move by means of the various stages of the tower. Kiln systems with preheaters are a lot more fuel effective than extended kilns, making use of up to 50% less energy.
Once the clinker has formed, and has arrived in the firing end from the kiln, it drops into a planetary cooler, exactly where the clinker is cooled to roughly 100C above ambient. It's then transported to the clinker storage silos.
raymond roller mill - raymond grinding mill for getting coarse powder
In recent years, with the industrial production of more and more demand for powder, more and more grinding equipment appears in the market. The Raymond roller mill is used to grind various of materials for getting coarse powder. Its applicable materials include dolomite, limestone, barite, talc, diabase, quartz, gypsum, bentonite, etc. In general, these materials are non-flammable and non-explosive materials with Mohs hardness no more than 7 and humidity below 6%. Compared with traditional Raymond mill, the new Raymond grinding mill has less energy consumption. If you want to get the 25 198m powder, you can consider using this Raymond mill for sale. Welcome to choose our Daswell Machinery!
The application of the Raymond millsis wide. It can be widely used in mining, chemical industry, construction, metallurgy and other industries. But in recent years, with the rapid development of society, calcium carbonate is used more and more widely, such as rubber industry, plastic industry, paint industry, paper industry and so on. So grinding equipment that can produce high-quality calcium carbonate is becoming more and more popular.
The Raymond mill for saleis a kind of grinding mill machine. It can process heavy calcium carbonate into white powder, which plays a very important role in industry. Moreover, it can not only reduce the cost of various industries, but also improve the performance of the products used.
Raymond roller mill for saleis mainly composed of main engine, analysis machine, blower, finished cyclone separator, motor and other parts. Among them, the main machine is composed of frame, inlet volute, grinding roller, grinding ring and other parts. In addition, the Raymond grinding mill can be matched with jaw crusher, bucket elevator, feeder, electric control cabinet, etc., to form a complete grinding production line. Here is the flow chart of our machine.
Our DR series of Raymond fine grinding millis hot sale. Its models include DR-1280, DR-1300, DR-1500, DR-1700, DR-1900, etc. Different specifications of machine has different roller number and product capacity. Pick up a suitable model for your business. If you have no idea about choosing the models, welcome to consult us and we will provide you with professional suggestions.
When working, the material to be crushed will be added to the main engine from the feed hopper. The roller grinding device in the main machine revolves around the vertical axis and rotates itself. Due to the action of centrifugal force during rotation, the roller swings outwards and compresses the grinding ring, so that the shovel shovel the material to be sent between the roller and the grinding ring, and the purpose of crushing the material is achieved by the rolling of the roller.
