Perlite is an acidic lava erupted by a volcanic eruption, a vitreous rock formed by rapid cooling,[1] so named for its pearl fracture structure. Perlite mines include perlite, obsidian and turpentine. The difference between the three is that perlite has circular arc-shaped cracks formed by condensation, called perlite structure, with a water content of 2~6%;Density is 2.2~2.4g/cm3; Moh's hardness is 5.5-7;Turpentine rock has a unique turpentine luster, with a water content of 6~10%; Obsidian has a vitreous luster and shell-like fractures, and the water content is generally less than 2%.
The perlite powder processing adopts the grinding method, and its production line equipment includes jaw crusher, cone crusher, Raymond mill (main part), bucket elevator, electromagnetic vibrating feeder, classifier, pipeline. The specific process flow of the device is as follows:
1. The crushing stage
First, the large amount of perlite extracted is initially crushed by a jaw crusher, and then sent to a cone crusher for further fine crushing. The reason why the two sections are broken is to achieve sufficient dissociation of the useful material of the ore. The milling stage provides better ore raw materials.
2. Screening stage
The crushed perlite material is not very uniform, and the mill has a specified feed size. In order to prevent the bulk material from entering the mill and causing adverse effects, the vibrating screen is generally used for screening treatment to make the perlite mill. The powder index has increased significantly.
3. Grinding stage
Next, the sieved perlite scraps will be transported from the bottom up to the silo by the bucket elevator, and then sent to the Raymond mill for deep grinding by the electromagnetic vibrating feeder.
4. Powder selection stage
Finally, the powdered perlite powder will be classified by the classifier. The unqualified fine powder will be sent back to the main machine for re-grinding. The perlite powder meet the fineness requirements will enter the finished silo through the pipeline device, and the powder tanker will be used uniformly. Pack it out.
To cater to specific material characteristics and meet customer requirements, SBM provides a range of grinding mills, including the MTM, MTW, LM, LUM, and SCM series.
To ensure environmentally friendly production, various measures are implemented, including the adoption of dust removers and sealing at each component.
SBM's solutions are highly automated, characterized by the utilization of a centralized control platform. This allows for the monitoring and effective control of the entire production process, resulting in significant savings in labor costs.
