Granite is one kind of igneous rocks formed by the condensate of magma below the surface. The main component of granite mine is quartz, feldspar and mica. The crushed granite rocks also can be used in cement or to be filled in Dams. In addition to being used as advanced architectural decoration project and the hall ground, Granite is also the best material for sculptures.
Granite Stone Crushing Process:
Big granite materials are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing. After first crushing, the material will be fed into cone crusher by belt conveyor for secondary crushing; then the crushed granite materials will be transported to vibrating screen for separating. After separating, the aggragates that can meet your requirements will be separated out as final products, while the other aggragates will be returned to cone crusher. This whole process can form a closed circuit for aggragates. Size of final products can be combined and graded according to your specific requirement.
Basalt is a very common igneous rock. It is the most common rock in the Earth's crust. Almost all oceanic crust is made of basalt and basalt is a common extrusion from many volcanic regions around the world.

DMAN Stationary Basalt Crushing Line In Jeddah
Project Background:
Location: JeddahRaw Material: basaltFeed Size: below 700mmOutput Size Requirement: 0-5mm, 5-10mm, 10-20mm, 20-30mmCapacity: about 250tph Working hours: 15 hours per dayInstallation Time: Late 2011
The costumer’s special requirement:
Most of the aggregates buyers need the final product with very cubic shape, it is hard to achieved by normal crushing machineThe capacity should definitely reach 250tphWe need all steel structure foundation for the whole crushing plantFast after sale service and short delivery time of spare parts (our people will visit client’s site and remind the plant operator order spare part in advance)
Highlight of Dingmandesign:
Stockpile before cone crusher, evenly feed material into cone crusher, avoid overloading or empty running of cone crusher, also the jaw crusher and cone crusher could operate separately.Stockpile before VSI crusher, avoid overloading or empty running of VSI crusher down, also the VSI crusher and other crushing machine could operate separately.Tertiary VSI crusher, used for aggregates shape trimming. The shape of final product processed by VSI will be more cubic, which ensure the aggregates sell good price.Two-way valve before VSI crusher, the customer choose shape-trimming the aggregates or not, according to the aggregates buyer’s requirement.Two-way valve on 20-30mm aggregates, the customer choose producing 20-30mm aggregates or not, according to the market demands.
Customer Feedback:
“Our aggregates sells very well because of the cubical shape, nowadays more and more clients cares more about the aggregates shape, e.g. the airport project etc, we are considering add new crusher to enlarge the scale of the existing plant. So far so good.”
Construction and demolition (C&D) materials account for almost 22 percent of the waste stream. Many of these materials can be reused or recycled, thus prolonging our supply of natural resources and potentially saving money in the process.
Common Construction and demolition materials include lumber, metals, drywall, masonry (brick, concrete, etc.), carpet, plastic, pipe, paper, cardboard, rocks, dirt, or green waste related to land development. Of these, metals are the most commonly recycled material while lumber makes up the majority of debris that still goes to a landfill.
Construction waste recycling is the separation and recycling of recoverable waste materials generated during construction and remodeling. Some materials can be recycled directly into the same product for re-use. Others can be reconstituted into other usable products. Unfortunately, recycling that requires reprocessing is not usually economically feasible unless a facility using recycled resources is located near the material source. The most important step for recycling of construction waste is on-site separation. Initially, this will take some extra effort and training of construction personnel. Once separation habits are established, on-site separation can be done at little or no additional cost.
Grinding Plant in Tunis
Materiel: dolomite
Grain size of finished product and capacity: 100 mesh ( d90% ), 325 mesh ( 10% )

Manufacturing Sand From Rocks With B-VSI-7611 in UAE
The introduction of B series Deep Rotor VSI cone crusher is born to resolve two problems in quarry field: the shortage of natural sand resources driving investors to resort to sand making machinery for artificial sand; the increasingly strict market demand for better aggregate shape.
Case StudyA quarry operator in the UAE plans to expand their crushing and screening plant in order to cope with an increasing demand in chip and sand in the market.The raw material is marble. They already have one primary jaw and a secondary impact crusher. Final products they required is 0-5mm; 5-10mm; 10-20mm (total 3 products). Yet, material comes out from the impact crusher are mostly above 20mm. The secondary impact crusher has been running at smallest discharge opening, yet still unable to yield products with required fines requirements.SolutionAfter consultation with Dingman engineer, they would like to add a B Series Deep Rotor VSI-7611 in the existing plant. This machine will further process the current outputs (20-40mm) into 0-5mm; 5-10mm; 10-20mm.The B-VSI is designed to produce find sand size product with good cubical product shape. After commissioning, the capacity of the plant is proved to be well increased to the capacity of 150t/h which lives up to his previous expectation.Advantage of B-Deep Rotor VSI Crusher Rotor is the heart of VSI, and the success of Dingman B-VSI should be attributed to the application of advanced design of its deep rotor.The deep rotor is about 50% bigger than that of normal rotor, which means there is a greater space between distributor and feed eye ring, as well as between the upper and lower wearing plates. Capacity in this way is increased at least by 30% compared to the traditional VSI crusher.
DMAN Stone Crusher in Angola
Case StudyA Crushing Plant invested by Chinese Government aims to crush Granite Stones for road construction. The detailed requirements are as following:Raw material: GraniteFeeding Size: 800mm Output size: 0-5mm, 5-20mm, 20-40mmProcuction ProcessThe raw materials are unloaded by trucks into the hopper. By vibrating feeder, raw materials are regularly fed into Primary Jaw Crusher which could reduce 800mm stones into approx.150mm. The half-finished products from Jaw Crusher will be conveyed by Belt Conveyor. #1 and piled up into the transmediate storage hopper. Another small Feeder under the stockpile will feed the stored materials regularly into Belt Conveyor #2 so as to transport the material to the following Cone Crusher S51''. After secondary crushing, products will be conveyed bt Belt Conveyor #3 & #5 to the Vibrating Screens for size separation: 0-5mm, 5-20mm, 20-40mm and +40mm. The unrequested products which are bigger than 40mm will be returned to the tertiary Cone Crusher S36'' by Belt Conveyor #4 for further crushing, while products with requested size will be piled up by Belt Conveyor #6. Natural fines from the grizzly bar of the vibrating feeder are conveyed by Belt Conveyor #7 as separate stone scrap.Flow Chart for This Crushing Plant
