Problems solved by technology
However, the vertical mill has the disadvantages of complex structure, large floor space, high cost, and high energy consumption for system ventilation. It also has the problems of large vibration and rapid wear of the roller surface. Due to the high pressure, the cakes that come out need to be punched. Dispersed classifier, resulting in complex system process
However, the particle size of the material discharged from the horizontal mill is not very uniform, and the appearance and shape of the fine powder are not regular enough, especially for grinding slag and cement clinker with poor grindability. If you want to improve the product quality of the powder And the proportion of qualified products requires further grinding, which will inevitably reduce the stability of the material layer and increase the overall energy consumption; and during the operation of the mill, the vibration is relatively large, and the safety performance and service life need to be further improved.

Embodiment Construction
[0029] The present invention will be further described below in conjunction with drawings and embodiments.
[0030]The present invention includes: a cylinder body 9, a pressure roller 4, a sliding support seat 2, a transmission device, a pressurizing device 5, a spherical grinding device 6, a material guiding device 7 and a scraping device 8. The pressure roller 4 is placed in the cylinder 9, and the inner wall of the cylinder 9 is provided with a cylindrical main liner 6-10 corresponding to the pressure roller 4. Both ends of the cylinder body 9 are respectively provided with inlet and outlet ports 12 and 3 . Two main sliding bearing seats 2-1 and two auxiliary sliding bearing seats 2-2 are correspondingly placed on both sides below the cylinder body 9, and the structures of the main and auxiliary sliding bearing seats 2-1 and 2-2 are the same as those in the prior art. , all contain support tile 2-3, support seat 2-4 on the spherical surface, support seat 2-5 under the sphe...

The invention provides a horizontal roll mill, comprising cylinder body, pressure roll, sliding bearing support, driving device, pressure device, material guide device and scraper device. The pressure roll is set in the cylinder body and two ends can be pressed and controlled by the pressure device which can add pressure in synchronization. The cylinder body is born by four sliding bearing supports which are set in asymmetry. The material guide device adjusting material lead on line and the scraper device, which can be adjusted conveniently, are set in the cylinder body. The cylinder body is driven by a big gear of driving device set in the middle of cylinder body. At the tail end of cylinder body a ball milling device comprising spherical mill roll, roll spindle, shaft sleeve, connecting plate and pin is set. The invention is provided with reasonable structure, small occupied area, low investment, low energy consumption, low wear consumption, low noise, high producing efficiency and good product quality. It is especially suitable for grinding to slag and cement clinker with worse grind ability and can satisfy the demand of high specific surface area of slag powder. It can grind slag thin to 430m<2> / kg in one time while it is provided with low flow speed of grinding material, small equipment wear and long service life.
Description
technical field [0001] The invention relates to a grinding device, in particular to a horizontal roller mill suitable for grinding slag and cement clinker. Background technique [0002] For a long time, in many industries such as building materials, metallurgy and mining, material grinding has always been dominated by ball mills. Due to its simple structure and strong adaptability to materials, the ball mill has been widely used in many fields of industrial production since its appearance in the early 20th century, and has become the first choice for people to grind various materials. The grinding principle of the ball mill is to use the material to be ground and the steel balls and steel sections mixed in the circular cylinder to impact, crush and grind the material during the process of being lifted and thrown, so as to achieve the fineness of the ground material. Purpose. However, due to the invalid collision between the grinding bodies and the impact of the grinding bo...
