Bulgur milling using roller, double disc and vertical disc mills
The roller mill had the highest milling yield (99.19%). Smooth and glassy particle surface was obtained due to the sharp-to-sharp operational principle of the roller mill (cutting effect). The quantity of coarse (/2.20) bulgur particle was higher than that of middle (2.20/2.00) and fine (2.00/0.50) bulgur particles.

Vertical Roller Mill Operation in Cement Plant
The cement rotary kiln. When operating the vertical roller mill, the operator must control the inlet and outlet air valves to make the air volume of the system in a balanced state, so as not to affect the air pressure at the back end of the rotary kiln. We are AGICO, a professional cement equipment manufacturer and cement plant contractor.
operational principle of master roller in vertical r
2.1 Principle of vibrating rollers The eccentric masses of a vibrating drum are shafted concentrically to the drum axis, resulting in a mainly vertical loading of the soil. This implies the main characteristics of vibrating drums, the lager compaction depth and higher ambient vibrations compared to oscillating rollers. 2.2 high compaction.
