Background
Mr. Martin are from Ghana, he needs the limestone grinding line. At first, the processing capacity is required to be 5 tons per hour, the raw material size is 5-100mm, the material is made by natural sodium borosilicate nacaB5o6 (OH) 6.5h2o or crushed, the humidity is 4%, the MOHS hardness of ulexite is between 1 and 2, and it is very sticky when wet, and the particle size after grinding is required to be 325 meshes. Finally, the packaging bag is packed with a 1.2-ton big bag packaging machine.
Solutions
According to client’s requirement, we choose the grinding mill 5R4119 which can meet above requirements. Firstly, raw material should be crushed by the hammber crusher to the size specified, then the crushed stuff is elevated into the hopper by the bucket elevator, through the vibrating feeder, evenly and continuously into the grinding chamber for power-processing. After this, the ground stuff is carried by the air flow from the blower into the separator for screening. The fine power is blown into the cyclone collector and are poured out through the output-powder valve as the final product and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The airflow system is closely sealed up and circulated under condition of negative and positive pressure. Because the stuff contain some moisture, and the heat generated during the grinding process makes the moisture evaporated, what’s more, the pipeline joints are not airtight and therefore the external air is sucked in, all these will increase air-current in circulation and disturb the circulation balance. The balance of the air current in circulation can be realized by adjusting the pipeline of extra air current between the blower and the grinder mainframe. After that, the powder carried by the extra air current will be collected by the dust filter. At the same time, the air current will be charged into atmosphere after purification.

Feedback
Mr. Martin's feedback on limestone grinding line: After the production line has been running for a period of time, we are very satisfied. First, the capacity can meet our requirements, and secondly, the granularity after grinding can also meet our needs. In this process, we are also satisfied with your service.
