Granite block mining
Granite is composed of feldspar (usually potash feldspar and oligoclase) and quartz, with a small amount of mica (biotite or muscovite) and minor accessory minerals, such as zircon, apatite, magnetite, ilmenite, and sphene. Granite has greater strength than sandstone, limestone or Marble and is correspondingly more difficult to quarry.
Granite is a product for decorating walls or interior space of buildings. It is now one of the most essential building materials for the decoration, durability and protection of the buildings.
Granite block mining equipment
Gulin® is a famous granite block mining equipments manufacturer in China, and offer types of machines like crusher, grinding mill and screening machine for granite mining plant. We also design granite mining process flow chart for granite mine in India, Pakistan, South Africa, Sri Lanka, Nigeria, China, USA, Qatar, Ethiopia, Vietnam, Italy, Yemen, Ghana, Zimbabwe and Malaysia.
Granite mining equipment is used to mine granite rocks for aggregates production. These granite aggregates are used primarily for building foundations, road, bridge and pier construction.
The actual block splitting from the sheet granite rocks or boulders is mainly done manually or in some cases by semi-mechanized method whereas the other operations, such as removal of overburden, lifting and transportation of cut blocks, etc. are carried out by mechanized method. There are a very few mines which adopt the modern method of block splitting by using flame-jet burner and diamond saw for cutting. Heavy-duty derrick cranes of capacity to handle 50-tonne blocks from a depth of more than 60 m have brought revolution in granite quarrying by way of more output with less cost. The percentage recovery of granite is quite low, and it varies from 5 to 15% because of unscientific granite mining method.
Granite business plan
First of all, we need to design a granite stone quarry business plan. This plan should include not only where and how to mine granite stone, but also the marble market, consumer information, and the advantages and disadvantages compared with our competitor. A good plan allows us to take a more long-term. This plan requires some professional knowledge about mining granite stone and choosing mining equipments. The knowledge about mining granite stone we can learn from relative books, but how to choose the mining equipments, we need to refer to the advertisements, and even investigate the strength of the manufacturer and which brand is the best seller that customer frequently choose.
And then we should to take action to transfer the granite stone quarry business plan into practice. We need to determine the mining site, and then we need to select mining equipment manufacturer to co-operate. Someone may think that we need to consider which mining equipments we need, and then to choose the manufacturer. It is a misunderstanding. A mature mining equipment manufacturer, such as Shanghai Zenith Mining and Construction Machinery Co., Ltd., will not only provide us with the reliable machinery, but also help us to configure a cost-effective potash ore production line, such as select which type of equipments and how the contact and cooperate with each other, and so on. We can contact the manufacturers by e-mail or telephone, but the best way is to visit the factories, by which we can survey more realistic and more comprehensive. This step is the key process in preparing the potash ore mining plant.
