Limestone is a sedimentary rock, is a crystalline structure, layered structure, the major rock-forming mineral calcite. (It may also contain a clay, dolomite, magnesium carbonate, iron oxide, silicon oxide, and some organic impurities.). Most limestone fine texture, hard, strong weathering resistance. Limestone is widely distributed, both around, easy mining, processing easier. On the construction works for the foundation, exterior walls, piers, steps and pavement.
The first stage: primary crushing, you can use PEW European version of the jaw crusher
Raw material through the hopper, vibrating feeder evenly by the feed, fed to the jaw crusher for primary crushing, after primary crushing material after sieving and conveying the fine material from the feeder belt together to counterattack Crusher.
Jaw crusher is mainly used for a variety of ores and bulk materials of medium-grained broken, can be broken compressive strength of up to 320Mpa materials, sub-coarse and fine broken broken two kinds. It is the primary crushing device of choice.
The second stage: in fine crushing can be used HPT multi-cylinder cone crusher
Delivered to the back-breaking in crushing the material after crushing back-breaking, using round vibrating sieve material through the back-breaking crushed sieved: the larger particulate material returned to the impact crusher again broken; grain size according to the needs of qualified materials, grading by conveyor belt to a different stockpile for storage or directly to the construction site by truck.
HPT series of multi-cylinder hydraulic cone crusher device structure is optimized, significantly enhance the performance and capacity of crushing equipment. Hydraulic lubrication systems supporting the design to ensure reliable operation of the equipment at the same time, the operation control is more intelligent and more humane.
The third stage: crushing plastic, can be used VSI5X series sand making machine
VSI5X series of new VSI series sand making machine, Sand is developed on the basis of a number of independent patent property rights of a new generation of products, set three kinds of crushing modes in one, has become the industry's core sand equipment.
The fourth stage: after washing the sand, you can use the XSD series sand washing machine
Commonly known as bucket wheel sand washing machine, the company is using high efficiency sand washing equipment Sand with advanced technology development and production use.
