First of all, we need to know what the final product 0.2mm is like: Physical meaning: 0.2mm indicates the maximum allowable diameter of the particles (or the aperture through the sieve), that is, the size of all finished particles should be ≤0.2mm.
Definition of particle size standard
| Project | Parameter requirements | Test method |
| Target particle size | ≤0.2mm (D97≤0.2mm is more stringent) | ISO 3310 standard 80 mesh sieve |
| Allowable fluctuation | 70-80 mesh (ASTM E11) | Laser particle size analyzer auxiliary verification |
| Typical application | Building plaster/masonry gypsum | Screen pass rate ≥95% |
Baichy Heavy Industry's Raymond mill (YGM series) can usually meet the needs of 3tph (tons/hour) production capacity and 0.2mm (about 80 mesh) finished product particle size, but it needs to be confirmed in combination with specific models and technical parameters.
Baichy Heavy Industry's Raymond mill has a wide range of production capacity. When processing medium-hard materials (such as gypsum), by adjusting the roller pressure and fan speed, it can usually reach 3-10tph (depending on the material and fineness requirements).
Gypsum characteristics: Mohs hardness is about 2, easy to grind, and 3tph capacity is within the normal range for medium-sized Raymond mills.
0.2mm (about 80 mesh) is the typical fineness range of Raymond mills. The built-in turbine classifier can accurately control the discharge fineness (usually 80-400 mesh, i.e. 0.18-0.045mm). If a stricter particle size distribution is required, a secondary classification system (such as an airflow classifier) can be added.
Recommended models and configurations
YGM130 Raymond mill:
Capacity: 3-10tph (gypsum, about 3-5tph at 80 mesh).
Finished product fineness: 80-325 mesh (0.18-0.045mm).
Advantages: Energy-saving design, variable frequency control of the classifier, suitable for small and medium-sized production.
System matching
Pretreatment: Gypsum stone needs to be crushed to ≤25mm (jaw crusher is recommended).
Classification optimization: YGM's classifier is blade-type. If you need more precise control of fineness, you can consult Baichen whether it supports the installation of a turbine classifier (similar to the HC series).
Dust removal: It is recommended to use a pulse bag dust collector (to avoid gypsum powder dust).
Baichy Heavy Industry's YGM series Raymond mill can stably produce 0.2mm (80 mesh) gypsum powder with a production capacity of 3-10 tons/hour. It has a built-in partition classifier for precise fine control and supports partition and classification optimization. It is suitable for applications such as building plastering, masonry building formwork, etc., and provides urban crushing + powder metering solutions.
