Calcite is the most important rock mineral of the earth's crust and it accounts for over 40% of the total crust. It has trigonal system and three sets of complete cleavage. This mineral shows vitreous luster, even completely transparent to translucent. The hardness of calcite is 2.704-3.0, the proportion of 2.6~2.8. It has the function of strongly birefringence and the largest polarized light. Calcite has more than 200 kinds of species. It can be found in most countries, such as China, Mexico, Britain, France, Germany and the United States.
Quarry calcite mineral site is dependent on the geologic characteristics and the extent and thickness of the natural deposit. Open-pit mining and quarrying are most commonly used. Mining and quarrying stone generally require drilling and blasting, after which the rock is then transported to a processing facility on trucks and conveyors. The calcite quarrying plant mainly includes calcite crushing process and the grinding plant.
Calcite processing plants are generally constructed on the site of extraction. Processing of mined or quarried calcite requires primary and possible secondary crushing, depending on the sizes of aggregate needed. After crushing, the crushed stone and sand and gravel usually are sorted to size, moved by conveyors to bins or stockpiled. Then the crushed and separated calcite materials will be grinded by the grinding mill machine.
Calcite crushing process is the first mining stage of the whole production line. The main crusher machine made by SBM has jaw crusher, cone crusher, impact crusher, hammer crusher, mobile crushing plant and so on. As we all know, the calcite has the almost same content with limestone. According to experts, the calcite quarrying crusher machine can be used as the limestone crusher.
SBM professional crusher experts design the calcite crusher machine according this mineral's characteristics. The crushing machine involves jaw crusher and roller crusher. This step is followed by coarse screening to produce half to a single inch lumps for gravels and so on. Jaw crusher is the primary crushing machine it is mainly used to crush the large calcite materials into smaller size. For further smaller size materials, the secondary crusher machine can be used.
Cone crusher is the star product from SBM and it has large working efficiency. Combining the latest technological development with over 20 years' production experience, SBM cone crusher is suitable for hard and medium hard rocks and ores. It is the ultimate solution for secondary crushing to achieve uniform product size of calcite.
The sales performance shows that the cone crusher is welcomed by clients and we contact one customer to get the evaluation of calcite cone crusher "This cone crusher is the right machine to maximize my profitability. For high productivity, low operating and wear costs, long service life, and high product yield with desired fines, there is no better choice than a cone crusher from SBM."
Calcite grinding mill is used to get powder materials. The common grinding machine includes ball mill, Raymond mill and trapezium mill. The final grain size of ball mill can be down to 0.07 mm, the trapezium mill can grind the calcite powder to 400 meshes, and the ultrafine mill can grind the calcite powder down to 2500 mesh in diameter. Insisting the processing principle of "more crushing, less grinding", SBM suggests that the ball mill can help realize the grinding stage.
Ball mill is the most suitable machine for calcite powder plant. The refined powder fineness uniform through screening rate is up to 98%. The calcite ball mill has reliable operation because of the sealed gear box and pulley transmission smooth. The life-cycle of wear parts is about one year, which is 2-3 times longer than the other milling machine. Besides, the ring and roller are forged by special material with high utilization.
