ball mill. 1. sag mill is the primary tool for grinding. sag mill is used before the other mills. ball mill is a secondary, and it is used after the sag mill. 2. sag mill breaks the raw material into pieces for the further grinding. ball mill is used to grind the pieces of raw
short conversion time, vertical mill can convert different raw materials on the same two mills in a very short time to produce different products. (ball mills require longer cleaning times.) 10. low wear. there is no direct contact between metals during operation, so metal consumption is small.
vertical roller mill vs ball mill first of all, from the appearance point of view, there is a big difference between the vertical mill and the ball mill. the vertical mill is presented vertically and three-dimensionally from the ground, while the ball mill is lying horizontally on the ground and covers a relatively large area.
if you do not need a deep primary grind, a retrofit/conversion might be of value. a very high impact opportunity to increase your ball mill tonnage. a conversion is cheap in price as you can read in the footer. the cost of a ball mill conversion from overflow to grate discharge is ‘fairly’ affordable at $65,000 for a 13′ x 15′ mill.

the biggest characteristic of the sag mill is that the crushing ratio is large. the particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. the calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s
home / horizontal vs vertical mill selecting the right high-performance media mill for your application is not always simple. whether you are manufacturing pigmented inks, technical ceramics, coatings, cosmetics, pharmaceuticals or nano-scale high-tech products, it is important to find the mill that will save the most time and money over the life of the equipment.
depending on the abrasiveness of the raw materials and the particle size of the product, the ball mill consumes 3 to 4 times more energy than the raymond mill. the ball mill also consumes about 30% more energy than the vertical mill, but the fine powder of the raymond mill and the vertical mill. the content is lower than the ball mill.
are too large to be fed into the tube (ball) mill. (5) ground materials are dried by the flue gas from the kiln. fig.2 schematic process flow of vertical roller mill for grinding of raw materials vertical roller mills are adopted in 20 cement plants (44 mills) in japan.
hlm vertical roller mill. top equipment of blast furnace slag, composite dust and limestone large-scale processing. high capacity, advanced technology, high efficiency. max feeding size: 50mm. capacity: 5-700t/h. fineness: 200-325 mesh (75-44μm)
1. coal vertical roller mill can handle all types of coal. coal vertical roller mill is used for grinding and drying all types of coal. 2. reducing the power consumption of the raw material preparation effectively. according to the display of material production measured data, it can be saving electricity above 30% use of vertical roller mill
the vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. it is increasingly used as a solution for efficient grinding. within the cement industry, vertical roller mills are becoming more important as more cement producers look to increase their use of clinker substitute

however, the unit cost for wear parts for a ball mill is much lower than for a vertical roller mill. for a ball mill grinding opc to a fineness of 3200 to 3600 cm2/g (blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 eur per ton of cement.
re vibration vertical roller mill. there are a number of reasons for high vibrations in vertical roller mills, such as: 1. failure of the grout or cement material under the steel beams embedded in the foundation top, which allows oil to penetrate, further degrading the concrete. the anchor bolts, which are typically large in diameter, continue
