The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed. Product quality
You get a lot of powder with larger deviation from the hammering. A roller mill uses cylindrical rollers that grind the grain when it goes through them, which requires less horsepower then a similar capacity hammer mill. A roller mill gets a more consistent grind and smaller deviation then a hammer mill by rolling the grain instead of hammering it.
What is the difference between the two? Grinding process The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed.
Energy Saving and Noise Reduction. When the vertical mill is in operation, the grinding roller does not directly contact the grinding disc, and the vibration is small, the noise is low, and the sound is soft. Generally, it is about 80 dB, which is about 20 25 dB lower than that of the ball mill.
05/05/2020· There are many differences between vertical roller mill and ball mill,not only in production efficiency.Which equipment to choose depends on your actual production efficiency, site and budget. Vertical roller mill adopts three dimensional structure,which needs less space,ball mill is just the opposite.And vertical roller mill is cheaper than ball mill,if you
09/08/2016· Vertical grinding mill is mainly applied to ultra fine powder processing of medium and low hardness, Mohs hardness of 6 non explosive brittle materials. Ball mill is the material after being broken, and then smash the key equipment. Vertical mill belongs to "smash the bed," the grinding equipment; different with "single particle crush" the ball mill:
23/05/2014· A vertical roller mill is an energy efficient grinder that grinds items into incredibly fine powders used for ceramics, cements, pyrotechnics, etc.
03/07/2018· Because the vertical grinding mill method is reasonable, the grinding work is fully utilized by the materials, and the grading is timely, avoiding the phenomenon of over grinding of the materials, so the grinding efficiency is high and the power consumption is low the above). 3. The vertical roller mill allows a large amount of air to be passed,
The difference between vertical roller mill and ball mill The ball mill is generally composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The cylinder body is provided with an abrasive body, the cylinder body is made of steel plate, and the steel lining plate is fixed with the cylinder body, and the grinding body is generally a steel ball,
Operating a ball mill is quite simple as it lacks any moving mechanical parts within the mill. The system is quite versatile and is designed to accommodate variation in mill feed quantity and quality. On the other hand, the vertical roller mills is quite a complicated and sophisticated equipment with hydraulics that controls the rollers.
