which type of crusher is suitable for processing granite | fote machinery

With the development of the stone crushing machine, the occurrence of new materials and advanced techniques, more and more granite crushers are manufactured in the market, and the differences in their prices are widening.

Granite is a kind of igneous rock, also known as acid crystalline plutonic rock, which belongs to hard stone. It is made of feldspar, quartz, and a small amount of mica. Granite is dense and has a granular structure.

The main component of granite is silicon dioxide, which has a hardness of 6 to 7 according to Mohs hardness. Natural granite has different shapes and needs to be crushed to meet the demand for materials in various fields.

The color of granite depends on the colors and distributions of feldspar, a small amount of mica, and the melanocratic mineral. The colors are usually gray, red, roseate, or gray alternating with red.

After processing and polishing, the surface of granite will form a beautiful speckled pattern with different shades of color. The pattern is characterized by fine and uniform grains, with star-liked mica highlights and sparkling quartz crystals.

It is often used as the primary crushing equipment of granite and the large granite can be crushed to a particle size of less than 100 mm. During the crushing process of granite, a piece of granite is crushed by shearing, breaking, splitting and extrusion which makes the finished product more solid.

During the working process, granite jaw crusher runs stably with lower faulty rate and longer service life. It also has the advantages of small investment, large crushing ratio, wide applications, and high working efficiency.

It not only realizes the selective crushing of materials but also significantly increases the product fines ratio and cube content, greatly reducing the needle-like materials and the wear on the parts.

In addition, the cone crusher also uses a modular design. Through the replacement of the cavity type, it can realize the conversion of coarse, medium and fine crushing, improve the production efficiency, and also meet the large production demand.

The discharge port, screen and key parts of the cone crusher are equipped with a spray system, which can humidify the dry material, increase its weight, and effectively inhibit and reduce dust pollution.

The dilution of noise first passes through the environmental protection layer built into the cone crusher. This wear-resistant buffer layer not only dilutes the noise but also protects the machine and reduces the noise around workers.

However, the hammer and counter-attack plate of the impact crusher are easy to wear. Especially when crushing hard rocks such as granite, the wear is more serious and the wear parts need to be replaced frequently, which not only increases production costs but also extends downtime.

The granite aggregate processed by the sand making machine has a solid shape, strong adhesion and long durability, and is widely used in highways, railways, bridges, airports, real estate and other fields.

If the material requirements are low, the jaw crusher and the cone crusher are required to crush the granite. Or else, the sand making machine should be added for the final shaping of the material.

The granite sand making machine is stable in operation. the failure rate is very small, the output of sand making machine is huge, and the finished products are uniform with cubic shape, which is favored by downstream users.

The semi-mobile granite crushing plant is mainly designed to eliminate the problems that occurred in the actual crushing site for users. The integrated unit installation and flexible movement solve the obstacles of crushing operation for the customer, and the operation saves much time and effort.

The equipment adopts a half vehicle-mounted structure with tires as the chassis. The flexible collocation allows it to be used in combination with different crushers to meet the different needs of customers.

Mr. Paul from the UK sent his feedback: "since the introduction of this semi-mobile granite crushing machine in our plant, the output of our entire production line has stabilized. Our company is very grateful for the benefits this equipment provides for us."

Based on the traditional semi-mobile crusher and combined with the properties of granite, the portable granite crushing plant is specifically designed. It has significant advantages in both structure and performance, arousing the attention and favor of users at home and abroad.

Portable granite crushing plant is mainly composed of four parts: feeding system, crushing system, screening system and conveying system. The purpose of the feeding system is to feed granite materials into the crusher or the screening machine; the crushing system is used to crush granite; the screening system is used to granite gravel screening; and the conveying system is used to transport the finished gravel products.

The materials that larger than the particles are returned to the sand making machine and continue to be crushed. Small substances are sent to the sand washing machine for cleaning. The cleaned materials are sent to the finished product pile by the conveyor.

The finished product of the sand and gravel treated by the production line has a uniform particle size, good granular shape and low output rate of stone powder, which can fully meet the demand of strict requirements.

Granite is a material with high hardness and high silicon content, which is difficult to crush in actual crushing operations, or it is relatively high in crushing cost. If an unsuitable crusher is selected, the damage speed of the wear parts will be accelerated, and it will need to be replaced even in a few days, and the running cost will increase.

Since granite is a brittle material, the improper crusher will increase the content of the needle-like material and increase the internal crack of the finished product, thereby reducing the application range and increasing the production cost.

Two or more crusher types will be used in the granite crushing process, so the combination of crusher is especially important. A good production line will make the crushing process run more smoothly, and save labor power and material resources while increasing production.

The crushing of ore cannot avoid the generation of dust. The diffusion of dust will not only pollute the environment, but may cause downtime if it is slightly inadvertent. Therefore, when the crusher is selected, its sealing system and dust control methods should be perfect.

Under the background of environmental protection, reducing noise interference is also one of the channels for environmental protection. Therefore, when choosing a crusher, noise issues should also be taken into account.

zimbabweans in granite mining areas see little revenue from prized stone

Trucks carrying slabs of black granite drive toward a weigh station at the Nyamapanda border post in a town on Zimbabwes border with Mozambique. Most of the black granite mined in Zimbabwe is exported to its neighbor to the east.

Trucks carrying slabs of black granite drive toward a weigh station at the Nyamapanda border post in a town on Zimbabwes border with Mozambique. Most of the black granite mined in Zimbabwe is exported to its neighbor to the east.

In 2016, Zimbabwe exported $45.5 million in granite, and the countrys black granite is particularly valued. Theres just one problem: Zimbabwes miners and mining communities are receiving a pittance of the revenue generated by their natural resource.

Trucks carrying slabs of black granite drive toward a weigh station at the Nyamapanda border post in a town on Zimbabwes border with Mozambique. Most of the black granite mined in Zimbabwe is exported to its neighbor to the east.

Loads of black granite are a near-constant sight here, where the stone is mined and loaded for transport to Mozambiques Port of Beira. From there, most of it is shipped to wealthier nations for cutting and polishing, and then it is sold to builders, who prize it for countertops, floors, facades and more.

But as Zimbabwes government works to create a system that ensures that it benefits from all the gold and other resources extracted from beneath the earths surface, the miners and their communities receive only a small fraction of the value of their black granite.

And the companies that blast blocks of the stone from quarries often companies not based in Zimbabwe do more harm than good to local people and to their environment, people who live near the quarries say.

We dont see economic and social benefits, says Peter Sigauke, chief executive officer of the Mutoko Rural District Council. Black granite has been mined since 1972, [and] the mining companies are not building any infrastructure.

Granite makes up 1.6 percent of Zimbabwes total exports, far below gold (32 percent of the countrys total exports) and raw tobacco (14 percent). In 2016, the country exported $45.5 million in granite, according to data collected by the Observatory of Economic Complexity at the Massachusetts Institute of Technology. Fifty-six percent of that granite goes to Mozambique, and the rest goes to Italy, Belgium, Spain and other countries. From there, black granite winds up all over the world, including in high-end buildings such as Denmarks Royal Danish Library, the facade of which is built entirely from the stone.

The Royal Library in Copenhagen, Denmark was built with black granite from Zimbabwe. It's just one of many examples of how the prized stone is used around the world, but people in the areas where the granite is mined say they earn very little the mining process.

Until late 2017, when long-time President Robert Mugabe was pushed from office, the government required that Zimbabweans hold at least 51 percent of the shares in every mining company operating in Zimbabwe, and at least 10 percent of those Zimbabwean-owned shares were to be given to local residents through what is known as the Community Share Ownership Trust.

The Mutoko Rural District Council tried in 2010 to get some of the unpaid revenues in court, but Ignatius Chombo, then Zimbabwes minister of local government, public works and national housing, instructed the council to withdraw the case in exchange for taking in $1 per metric ton, Sigauke says.

In the past, Sigauke says, that brought in between $160,000 and $200,000 each year, but thats based only on proven exports. Sigauke says that one international company has exported granite for nearly two years without paying the development levy, by claiming that the granite slabs are samples that need to be tested. Sigauke declined to name that company.

The money the council receives is far less than what it got prior to 1996, when black granites status was changed by the Zimbabwean government from a natural stone to a mineral, Sigauke says. As a natural stone, both mining operations and royalties for black granite were managed locally, he says. Now that black granite is considered a mineral, the central government manages mine licenses and other regulatory details and collects the royalties.

People in Mutoko say they dont see any benefits from the granite. The areas roads are mostly gravel, save for the commercial center, and even that section has just a few shops, a business center and fuel stations. Most of the area lacks electricity.

Edward Muvuro, human resources manager for the Natural Stone Export Company, which has mined black granite for decades, says local people dont know the full story of how the company aids the community.

He says that, in addition to employing local people most of its 800 workers are from the area, he says the company has pledged $1 million to the community. It has built schools and hospitals and is now building homes for teachers, Muvuro says. Thats on top of paying fees for a handful of academically gifted students at each school, he adds.

Muvuro also downplays the value of the granite mined in Mutoko. Nearly all of it is exported in raw form, he says a far cry from the polished, high-price version on display at the Royal Danish Library.

In general, Muvuro says, a 1-square-meter (10.8-square-foot) slab of raw granite that is 8 millimeters thick (.31 inches) sells for $50 to $60. Its usually more expensive to buy black granite that is processed and polished in Zimbabwe than to buy slabs that are processed and polished elsewhere, he says, because the equipment used elsewhere is more efficient.

This year, Zimbabwes Ministry of Finance and Economic Development instituted a 5-percent tax on the sale of all raw granite, to encourage the granite industry to process the stone in Zimbabwe. But buyers are wary of black granite that comes in any form but raw, Muvuro says, because some sellers use artificial hardeners, which can crack over time.

Sigauke says local authorities should be involved in the processing of permits so that, before mining begins, the authorities can carry out environmental impact assessments and ensure that contracts are brought before local councils.
