Cement crusher plant

Cement crusherplant

Cement crushers are stone crushers or rock crushers used for
crushing cement materials or cement related products in cement plants. Cement
is a most common construction materials used in modern industries through
cement production lines or cement grinding plants. In the cement plants, we
need cement crusher, cement mill, conveyors, feeding equipment etc.

Cement crushers
are the important cement machines used in cement production line. Generally it
is used in cement crusher plant. Big raw materials firstly are crushed by
cement crusher, then appropriate raw materials dust enter into the cement mill
for milling with stone milling machine.

Cement crusher plant application in industry

Invention of cement crusher plant provides a material basis for the
development of construction. From land engineering to water, underground
engineering, cement plays an important role. Cement has been invented for a
hundred years and it has always been widely used, becoming the most consumed
binder. In order to meet the needs of different construction, the increasing
varieties of cement have reached more than 200 kinds. And the cement mill is one
of the growing kinds.

The cement grinding mill varies from
traditional ball mill to new European trapezium grinding mill. Cement crusher
includes jaw crusher, cone crusher, impact crusher, etc. In cement mining, cement
grinding mill and cement crusher play a very important role. They can crush or
grind the cement to required fineness for industry application.

Cement crusher plant recommendation

In cement production process, cement
crusher is very important since most of the raw materials will have to be
crushed before being used to process cement, such as limestone, clay, iron ore
and coal, etc. Limestone is the largest amount of raw material during cement
production. Before limestone mining, limestone is generally of large size and
high hardness. Therefore the limestone crushing is very important in the whole
material crushing. Usually we choose jaw crusher for limestone crushing since
jaw crusher is of easy principle, convenient maintenance and low cost. However,
if the whole cement mining scale is of large size, we usually choose cone
crusher or impact crusher to assit jaw crusher and to be secondary or tertiary
cement crusher machine. Also cement conveyor is used to transport these
materials to next procedure, such as vibrating cement screen to screen out
required fineness. In some production sites, we use a whole mobile crusher to
complete the whole cement crushing and screening production, since the mobile
crusher is equipped with jaw crusher, impact crusher or cone crusher, vibrating
feeder, vibrating screen, etc.

Some ways to increase the cement grinding

1. To enhance the ventilation of mill ; to
improve the surroundings of mills to enhance the ventilation of mill is the
effective methods to increase the production capacity and to reduce the power

2. To adopt the new type of scaleboard
to improve the material of the mill parts. The new type easy grinding ability
spare parts are widely used nowadays for prolonging the service life of parts
and grinding media .

3. To add grinding aid to increase the
grinding efficiency; there have many kinds of grinding aids, most of them are
organic surface-active material. Some research has shown the grinding aid of ethanol,
butanol, butanol oil, and rolamine work out to be fine.

4. To reduce the temperature of cement
to improve the quality of cement .High temperature will cause the dehydrate
gypsum dewatering in cement processing, which will make cement false setting
and material cementation.


Cement Manufacturing Process

Cement Manufacturing Process

The cement manufacturing process begins when limestone, the basic raw material used to make cement.

Cement Manufacturing Process

Cement Manufacturing descripation

The limestone is combined with clay, ground in a crusher and fed into the additive silos. Sand, iron and bottom ash are then combined with the limestone and clay in a carefully controlled mixture which is ground into a fine powder in a 2000 hp roller mill.

Next, the fine powder is heated as it passes through the Pre-Heater Tower into a large kiln, which is over half the length of a football field and 4.2 meters in diameter. In the kiln, the powder is heated to 1500 degrees Celsius. This creates a new product, called clinker, which resembles pellets about the size of marbles.

The clinker is combined with small amounts of gypsum and limestone and finely ground in a finishing mill. The mill is a large revolving cylinder containing 250 tonnes of grinding steel balls that is driven by a 4000 hp motor. The finished cement is ground so fine that it can pass through a sieve that will hold water.

Tips for selecting cement crusher plant

Cement production line: is a production line that is composed of a series of equipment for producing cement. The processes for producing cement mainly include: crushing and prehomogenization, raw material homogenization, prehearing and decomposition, the burning of cement clinker, and the package of cement. Crushing: in producing cement, most of the raw materials such as limestone, clay, iron ore and coal need crushing. Limestone is the major raw material component of cement producing, and its granularity is much bigger, rigidity is relatively high. Therefore, the crushing of limestone plays a significant role in the cement production line.

There are several factors to take into consideration in selecting cement crusher plant. These factors are: the rigidity (mainly refers to compressive strength) of raw material, the corrosivity (with free quartz content), and the viscosity (water content and clay content). After the consideration of these factors above, you can then choose the crushing equipment that corresponds with the specific characteristics of the raw materials. The cement manufacturing processes mainly include 5steps: primary, secondary crushing; pre-grinding, raw material grinding; calcining; clinker crushing &grinding; cement grinding &conveying.

Primary and secondary crushing, as the first step of cement production line, is of crucial importance, so is the selecting of cement crusher plant. There are many types of crushers that can be used for primary and secondary crushing, such as jaw crusher, impact crusher, hammer crusher and cone crusher; a specific introduction about the difference of various types of crushers is as following:
Jaw crusher is a kind of primary crushing equipment which can be used for crushing various rocks, such as basalt, granite, marble, and other ores; while impact crusher has its unmatched excellent performance in secondary crushing, tertiary crushing, and material recovery. Hammer crusher, which can replace the traditional two-stage crusher and help simplify the process flow, and save infrastructure investment, is the best equipment for crushing limestone. Cone crusher is a kind of popular stone crusher; the hydraulic cone crusher can replace the spring cone crusher in mining and building industry.
