Marble crusher
- Marble basics
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. It is commonly used for sculpture and as a building material.
Marble forms from limestone with heat and pressure over years in the earth's crust. These pressure or forces cause the limestone to change in texture and makeup. The process is called recrystallization. Fossilized materials in the limestone, along with its original carbonate minerals, recrystallize and form large, coarse grains of calcite. Marble can be divided into three types: dolomite such as magnesite, forsterite, and calcite.
Marble does not split easily into sheets of equal size and must be mined with care. The rock may shatter if explosives are used. Blocks of marble are mined with channeling machines, which cut grooves and holes in the rock. Miners outline a block of marble with rows of grooves and holes. They then drive wedges into the openings and separate the block from the surrounding rock. The blocks are cut with saws to the desired shape and size. Uses of Marble
- Colorless or light-colored marbles are a very pure source of calcium carbonate, which is used in a wide variety of industries. Finely ground marble or calcium carbonate powder is a component in paper, and in consumer products such as toothpaste, plastics, and paints. Ground calcium carbonate can be made from limestone, chalk, and marble; about three-quarters of the ground calcium carbonate worldwide is made from marble.
Ground calcium carbonate is used as a coating pigment for paper because of its high brightness and as a paper filler because it strengthens the sheet and imparts high brightness. Ground calcium carbonate is used in consumer products such as a food additive, in toothpaste, and as inert filler in pills. It is used in plastics because it imparts stiffness, impact strength, dimensional stability, and thermal conductivity. It is used in paints because it is good filler and extender, has high brightness, and is weather resistant. However, the growth in demand for ground calcium carbonate in the last decade has mostly been for a coating pigment in paper. Marble crusher used in marble quarry
- In order to be used for buiding materials or industrial powder, marble must be crushed into small pieces. In this crushing process, we need marble crusher.
Marble crusher is the common marble mining machinery that used for crushing marbles into small size. In marble quarry, there are several mining equipmetns used in marble crushing and screening plant.
Vibrating feeder is the feeding machine that is used to feed stone materials evenly to the crushing machine. There are two types of vibrating feeder: inclined feeder and horizontal feeder. Some models have one motor, while the others have two motors.
Marble stone crusher machine has several types. Marble jaw crusher is the primary crushing equipment; it is used in primary crushing process in marble crushing plant. Impact crusher and cone crusher is the secondary crushing machinery. They are used in secondary or tertiary crushing process.
Vibrating screen is the Separator machine. It is used to screen out the suitable particles throuth screen with different sieve pore size. There are two kinds of screening machine: Circular Motion Incline Vibrating Screen and Linear Motion Vibrating Screens. According to the the screening requirements, we install different screen layers.
There is another marble crusher; it is not only used as crushing machine, but also the screening machinery. It is mobile marble crusher or portable crusher. It is installed crushing machine, vibrating feeder, vibrating screen and belt conveyor together. Marble crushing and grinding process
- Marble go through vibrating feeder into jaw crusher for primary crushing, after primary crushing, the marble stones fall into impact crusher or cone crusher for fine crushing. The final materials can be screened out the suitable marble particles using for buiding materials through screening machine. The unsuitable marbles return to the crushing process for re-crushing.
If you need stone powder, marble have to go through grinding process. We can use ball mill or scm ultrafine ginding mill as marble grinding machine. The finished size cans upto 0.005mm.
SBM is a professional stone crusher manufacturer in China, and has formed a complete product-chain that takes crushers and grinding mills as the main products, and vibrating screen, vibrating feeder etc as supplementary products. Now, our products have exported to many countries, such as USA, Libya, South Africa, Vietnam, Indonesia, Philippines, Pakistan, Brazil, Egypt, Zambia etc, and received high popularity.
