As we all know both the
Raymond mill and the
vertical roller mill are the common mining equipment which usually be used in stone powder grinding, however, compare with them, what difference between them?
First, the application VS.
Raymond mill and vertical roller mill has quite high market utilization, the application of the industry is more similar, such as metallurgy, building materials, cement, chemicals, refractory materials, pharmaceuticals, mine crushing mill. Vertical roller mill is more suitable for large-scale professional industries, such as cement and non-metallic mineral industry. Vertical roller mill comes with drying function, high cost performance in similar equipment; Raymond mill is traditional mill, the first mill, the quality is stable, more reassuring.
Second, the finish powder fineness VS.
Raymond mill has a long history, the grinding range of particle size is a bit coarse, adjusted between 30-325mesh; Vertical mill technology age is more recent, it is based on the Raymond mill, after technical improvements, particle grinding range will be finer, 325-3000mesh, and it owns drying system, reducing the moisture content of the material.
Thirdly, the internal structure VS.
Vertical roller mill is similar in appearance to the Raymond mill, but their internal structure is different so they work slightly differently. Running, vertical roller mill roller position is fixed after the adjustment, the roller itself is like a pinion to do the rotation movement, there is no direct contact with the disc, the bottom of the disc has been rotated, the roller and the mill gap in the material Rolling grinding. Inspection and maintenance, vertical roller mill roller can be released through the lever bracket. The internal structure of the Raymond mill and vertical roller mill vary greatly, Raymond mill spring plum rack mounted 5,6 uniform distribution of the roller, the roller around the central axis to do circular motion, the bottom of the blade raised The material is fed between the grinding roller and the side wall grinding ring. Raymond mill ring is fixed, it is the side wall of the mill.
