Stone Powder Production Machinery
Stone powder, also known as stone dust, rock dust, rock powders, rock minerals, soil remineralization and mineral fines, is a non-synthetic fertilizer consisting of finely crushed rock, containing minerals and trace elements, used in organic farming. Today, stone powder has a wide application in our modern daily life and modern industry. Every year, we send several sets of stone powder production machinery for our customers. To our pride, they all think highly of our mining machines. Here we focus on more details of the stone powder production machinery made by SBM.
Overview of Stone Powder Industry
As mentioned above, stone powder has a wide application. Common types of stone powder are usually made of limestone, but may also be basalt, a volcanic rock. The largest use of stone powder is in the production of paper, including ensuring the gloss on some grades of paper. Commercial grades of stone powder are supplied and transported as dry powder, semi-dry noodle or as liquid?slurry. Stone powder has also seen some use in?organic farming, as a?spray?applied to crops to deter insect damage, and in the case of apples, to prevent sun scald. Of course, the price of stone powder is also very inspiring, especially from China, where a great demand for stone powder is increasing due to the significant growth of national economy. It is no wonder there is a great demand for stone powder production machinery.
Production Process of Stone Powder
Stone powder production machinery is consisted of stone crushers, vibrating feeder, belt conveyor, vibrating screen, and stone powder production equipment. Typically, the production process of stone powder can be divided into two significant stages, including the crushing stage and grinding stage. Firstly, large stones are sent regularly by the vibrating feeder to the primary jaw crusher, and then they will be sent to the secondary jaw crusher to be crushed again. The crushed material then is sent by belt conveyor to vibrating screen to be separated. The suitable size can be sent to the VSI crusher, while unsuitable material is sent back to the secondary jaw crusher to be crushed again. The crushed material from the VST crusher is sent back to the vibrating screen to be separated. Then stone particles should be sent to the XZM Series ultrafine mill to produce micron stone powder. After that, the whole production process is finished. SBM can design different stone powder of different capacity according to customers’ particular requirements.
