Abstract
The utility model discloses a millstone structure of a vertical mill, which comprises a resistance ring, a lining plate and a base. The resistance ring is welded on the base, a material cushion is formed after materials are spread on a millstone, the lining plate is mounted on the base in an inclined manner, a certain inclination angle is formed between the base and the mounting surface of the lining plate, and the grinding pressure of a grinding roller to the millstone is perpendicular to the mounting surface, so that the base is well stressed. The millstone structure overcomes the shortcomings of a previous structure, the base of the millstone is evenly stressed, the bite angle between the millstone and the grinding roller is increased, and scouring erosion of a non-wear-resistant surface of the millstone is avoided.
Description
Technical field
The utility model relates to a kind of mill structure, relates in particular to a kind of Vertical Mill mill version.
Background technology
Current, in the Grinding Process in Cement Plants system, Vertical Mill is widely used occasions such as grinding raw material, cement, coal dust as a kind of main milling equipment.Vertical Mill has stable mechanism performance, higher abrasive efficiency and the life-span of growing.The big parts of in the Vertical Mill are exactly its mill device, and material cloth is spread on above the mill, through the rotation of mill, get rid of into the space of milling between the grinding roller and mill to material and mill.The liner plate installation form of present most of Vertical Mill mills lies against on the mill pedestal exactly, and the mill pedestal is uneven along the mill radial force; Nip angle between mill and grinding roller is too little, and material is difficult for getting into the zone of milling; Material directly contacts with the non-wear-resistant surface of mill on the mill, brush erosion mill.
The utility model content
The purpose of the utility model invention is to overcome above-mentioned weak point, makes the mill pedestal stressed evenly, increases the nip angle between the mill grinding roller, avoids the brush erosion of the non-wear-resistant surface of mill.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme: a kind of Vertical Mill mill structure, comprise resistance ring, liner plate and pedestal, and the resistance ring is the different ring-type flat steel bar of internal diameter, the ring ring is nested and is welded on successively on the pedestal; The certain angle of liner plate inclination is installed on the pedestal.
Resistance loop resistance block material material outwards throws away, and makes and forms one deck and the identical backing strap of resistance ring height on the mill, and the direct and non-wear-resistant surface friction of mill of material has been avoided in backing strap and the friction of the motion material above the backing strap, has effectively avoided the appearance of brush erosion.
The certain angle of liner plate inclination is installed on the pedestal, on the one hand, has increased the nip angle between grinding roller and mill, makes material get into the district's grinding of milling more easily; On the other hand, grinding roller has reduced the pressure of pedestal contact-making surface to the vertical and mill pedestal contact-making surface of power that mill applies, and the stress distribution that makes pedestal is with even, and the liner plate that tilts has simultaneously also prolonged material in the time that the district that mills is detained, and makes grinding more effective.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among Fig. 1: 1-resistance ring; The 2-liner plate; The 3-pedestal.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is done further explain.
A kind of Vertical Mill mill structure as shown in Figure 1, concrete scheme is: resistance ring (1) adopts flat steel bar to make, and divides inside and outside a few to be welded on the pedestal (3).The certain angle of liner plate (2) inclination is installed on the pedestal (3).
Claims (1)
1. a Vertical Mill mill structure comprises resistance ring (1), liner plate (2) and pedestal (3), it is characterized in that: said resistance ring (1) is the different ring-type flat steel bar of internal diameter, and the ring ring is nested and is welded on successively on the pedestal (3); The certain angle of liner plate (2) inclination is installed on the pedestal (3).
