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 don't need high productivity,roller mill is a better choice. I think this note,which called what is the difference between vertical roller mill and ball mill can help you.
The k parameter (Donda & Rosa, 2013) was used to evaluate the vertical mills performance, when compared to the ball mills. RESULTS AND DISCUSSIONS Energy consumption Figure 5 shows the averages of net energy consumption per each mill in the regrind circuit on a monthly rate. The data was obtained from the automatic control system of the circuits.
Colloid Mills vs. Homogenizers: 2 Critical Differences. Particle size reduction is key to the synthesis of stable and high quality products like emulsions, suspensions, and dispersions, all of which are used in a variety of industries. From cosmetics to pharmaceuticals, and chemicals to biotechnology, the process of reducing particle size can ...
The difference between ball mill and vertical mill in cement grinding Over the last three decades the vertical roller mill has become the preferred ball mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system.
However, if the material has a very low viscosity, ball milling is a better dispersing process than using a high shear mixing (vertical) system. Since organic pigments are more difficult to break down to their primary particles compared to inorganic pigments, ball milling is …

comparison between cement ball mill - onesittingdegreein. cement vertical mill vs ball mill these differences between cement grinding and grinding of raw materials made, compared to a ball mill, a vertical roller mill is, Learn More, All of the discussion is based on comparison to ball mill, between cement mill, United States' First Vertical Roller Mill for Cement.
In a vertical mill the bed of material is subject to such a high pressure that individual particles within the bed are fractured, even though the particles are very much smaller than the bed thickness. Early issues with vertical mills, such as narrower PSD and modified cement hydration characteristics compared with ball mills, have been resolved.
Ball mills are fine grinders, have horizontal ball mill and vertical ball mill, their cylinders are partially filled with steel balls, manganese balls, or ceramic balls. The material is ground to the required fineness by rotating the cylinder causing friction and impact.
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 (VRM) is quite a complicated and sophisticated equipment with hydraulics that controls the rollers.
Ball Mills Mineral Processing Metallurgy. 20191224Working Principle Operation. The apparent difference in capacities between grinding mills listed as being the same sie is due to the fact that there is no uniform method of designating the sie of a mill for example a 5 x 5 Ball Mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all other ball …
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.
comparison between ball mill and roller mill. What's the difference between ball mill and vertical roller mill. By Jordan shu – Sales Articles, This article is …
The difference between vertical roller mill and ball mill . of the grinding material is poor; (4) The system power consumption is 80kwh/t, and the roller press system has a large circulation amount, and it has to be transported by the belt conveyor and the lifting conveyor, so the system is dusty; (5) System operation rate: 85%90% Vertical mill process features: (1) The structure is simple ...
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, and ...
The space occupied by the vertical mill is only 50%~70% of the ball mill, and the occupied physical space is relatively smaller. 5. Lower initial cost. The initial construction cost, running cost and maintenance cost of the vertical mill are only 70%~80% of …
Answer: Before understanding the difference between milling and broaching we should know the need of finishing. Whenever a machining process takes place on the surface various defects are formed such as tool's mark on surface of the workpiece and Scalling or pitting. Some of the defects that are...
