Cement clinker is the semi-manufactured material which needs to be ground into powder to make ordinary cement. Clinker contains aluminosilicate and calcium carbonate minerals in varying amounts. The production process involves heating a mixture of limestone and clay to around 1,500 degrees Celsius, which produces clinker nodules of 3-25mm diameter. These are then ground into a powder to produce ordinary Portland cement, the most commonly used type of cement.
There are numerous reasons why cement clinker is an essential component in the manufacture of concrete in the construction industry. Here we look at 10 reasons why you need to buy cement clinker today:
1. The manufacturing process for Portland cement requires that a source of calcium, a source of silicon, iron ore and small amounts of alumina and manganese are mixed with each other and heated to form a molten substance which is then fed into rotary kilns. This is how clinker nodules are produced.
Cement is one of the most common building materials used in manufacturing concrete. You need to buy the right amount of cement for your project, or you could end up wasting both time and money. Here are 10 reasons why you should buy cement clinker.
1. It is a key ingredient in concrete – Cement is a key ingredient in concrete, which is one of the most widely used construction materials in the world. It is a mixture of water, aggregate and cement that hardens over time. It has been used to build structures such as bridges, dams and homes since the ancient Romans.
2. It can be used for many different projects – Concrete can be used for many different projects, including buildings, roads and sidewalks. You can also use it to create flooring or walls inside buildings.
3. It’s easy to work with – Cement clinker is easy to work with because it has a long shelf life and doesn’t require any special tools or equipment for mixing or pouring into forms that have been pre-cast or cast on site using molds made from plywood sheets cut out using jigsaws (circular saws). You’ll also save money on labor costs if you buy your own bagged cement instead of paying someone else to
Cement clinker is the key ingredient in cement manufacturing. It is formed by firing a mixture of limestone, clay and other additives at a very high temperature. Clinker is usually ground into powder together with gypsum and other additives to form the final product, Portland cement. Most cement plants import all of their clinker, as it can be very expensive to produce domestically.
Here are ten reasons why you should buy cement clinker from your trusted supplier:
1) High Quality: The quality of the clinker you buy will have a direct effect on the quality of your final product. You’ll need to ensure that your clinker has been properly stored and handled from the time it was produced until it reaches you.
2) Good Price: The price of clinker varies widely depending on supply and demand in any given location. As such, importing clinker from another region or country may offer significant savings for your company.
3) Flexibility: When you buy all of your clinker from one source, you reduce the complexity of your supply chain and decrease risk. This flexibility allows you to focus more on growing your business than worrying about keeping up with market fluctuations and dealing with multiple suppliers in many locations.
4) Reliability: A good
Cement clinker is the building material used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills. Cement clinker is usually ground using a cement ball mill. This is essentially a large rotating drum containing grinding media – normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers, with different size grinding media. As the clinker particles are ground down, smaller media are more efficient at reducing the particle size even further.
Grinding systems are either ‘open circuit’ or ‘closed circuit.’ In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in order to control the setting properties of the cement. Clinker grinding uses a lot of energy and the cement becomes hot – this can result in the gypsum becoming dehydrated, with potentially undesirable results – see the link at

Cement clinker is the semi-manufactured material, which needs to be ground into powder to make ordinary cement. The raw material for producing cement clinker is generally limestone mixed with a second material containing clay as source of alumino-silicate. Normally, an impure limestone which contains clay or SiO2 is used. The CaCO3 content of these limestones can be as low as 80%. Second raw materials (materials in the raw mix other than limestone) depend on the purity of the limestone. Some of the second raw materials used are: clay, shale, sand, iron ore, bauxite, fly ash and slag. When a cement kiln is fired by coal, the ash of the coal acts as the second raw material. Cement clinker is made by pyroprocessing of kiln feed into the preheater-kiln system.
The raw mix is heated in a rotary kiln at approx. 1450 degrees Celsius to produce intermediate product called “clinker”. Then it goes through further grinding with gypsum added before being conveyed to silos for storage from where it is dispatched either in bulk or in bags to its final destination.
The main reason for using cement clinker is that
A cement clinker is a hard material produced in the kiln stage during the production of Portland and other types of hydraulic cement. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
It can also be used for cement grinding, where fly ash and slag are ground together with clinker to produce composite cements, or blended with other materials, including gypsum, anhydrite and limestone.
Clinker consists of various calcium silicates including alite and belite. Tricalcium aluminate and calcium aluminoferrite are other common components. These components are often generated in situ by heating various clays and limestone.
Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kiln at high temperature . The products of the chemical reaction aggregate together at their sintering temperature, about 1,450 °C (2,640 °F).
The most common use for Portland cement is to
