Machine for Grinding Granite

Granite is an igneous rock that forms when magma cools slowly beneath the earth’s surface, forming large, easily visible crystals of quartz, feldspar, and mica. In our modern life, granite is commonly used in the construction industry. Every year, lots of customers inquire SBM about our machines for grinding granite. Until now, we have designed and installed several sets of granite processing line for our honored customers both at home and abroad. To our delight, those granite processing machines are working well. We always have a belief that every customer who uses our mining machines can realise their fortune dream. Today, we are walking toward this dream. Here we focus on more details of our machine for grinding granite, also called granite grinding unit.

Overview of Granite Stone Industry

Granite is a common widely occurring type of?intrusive,?felsic,?igneous?rock?which is granular and crystalline in texture. This rock consists mainly of quartz, mica, and feldspar. Occasionally some individual crystals are larger than the groundmass, in which case the texture is known as?porphyritic. A granitic rock with a porphyritic texture is sometimes known as a porphyry. Granites can be pink to gray in color, depending on their chemistry and mineralogy. Due to its high hardness, wear resistance, the granite stone is used as a senior architectural engineering in addition to the hall outside the ground, or of the material of choice for outdoor sculpture. Nowadays, with the rapid growth of real estate, the annual demand for granite stone and powder has been increasing significantly. The market of granite is so inspiring that mining investors buy a certain number of machines for grinding granite from China.

Overview of Granite Stone Mining Process

Generally, the mining process of granite stone can be divided into three main stages, including the crushing, grinding, and packing. Firstly, large granite stones should be crushed by different kinds of crushers, such as the jaw crusher, impact crusher, and cone crusher, etc. As we all know, granite stone has a high hardness, so it will takes a long time to deal with them. Secondly, small granite stones are sent to the storage hopper by elevator, and then evenly sent to the vibrating feeder. Later, those granite particles should be classified by the vibrating screen. Thirdly, small granite particles should be grinded into powder. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end.

Machine for Grinding Granite

In terms of machine for grinding granite,so many mining applications have proved that SBM’s XZM series ultrafine mill can be performed as a high efficiency granite stone grinding unit in the granite quarry. Compared with other machines, it owns a higher capacity, efficiency improving by 40% under the same amount of power supply and fineness requirement of product. Secondly, there is no rolling bearing and bolt in the mill chamber, therefore, the bearing and sealing elements will not wear out easily, and bolts will not loosen, which can make serious damage to the mill. Every ultra-fine mill is equipped with pulse filter and sound absorber, making the mill reach international environment protection stands and reduce dust and noise greatly.

Besides granite grinding unit, SBM can also design and install an entire set of granite processing line for our customers both at home and abroad. Nowadays, our granite stone grinding machines have got a good reputation among our honored customers. If you have some problem in the investment of granite industry, please contact us! SBM will help you reach the SBM of mining business.
