Abstract
The utility model relates to powder mill equipment, in particular to a millstone of a vertical roller mill. The millstone comprises a millstone body, wherein the millstone body consists of upper and lower split millstone bodies independently cast, and the two split millstone bodies are connected and fixed by connecting pieces. The split millstone of the vertical roller mill is fabricated without limitation of the casting capacity and a processing condition, so that a requirement on casting tonnage of a blank is reduced, the probability of pouring deformation of a large casting is reduced, and the millstone is convenient to process, assemble and transport.
Description
Technical field
The utility model relates to a kind of milling equipment, especially a kind of vertical roll grinder mill.
Background technology
The vertical roll grinder that cement and metallurgical mine industry are used, be applied to pulverizing cement raw material, clinker, slag, coal dust etc.The major function of vertical roll grinder upper millstone is exactly the supporting material bed, and the power that grinding roller is produced transfers to the reductor of bottom, and the torsion of reductor is transferred to the grinding zone.Along with Vertical Mill large scale development trend, the mill size is originally larger, and weight is more and more heavier, is subject to the restriction of casting ability, machine tooling scope more and more obvious.The large mill of size is processing difficulties not only, and assembling and transportation also waste time and energy, and impact is produced.
The utility model content
The utility model is for the defect existed in background technology, provides a kind of simple in structure, is convenient to the vertical roll grinder mill of processing and transportation.
For achieving the above object, the technical scheme of this novel employing is: a kind of vertical roll grinder mill, comprise the mill main body, the mill split that described mill body is formed by upper and lower two independent castings forms, and between two mill splits, by connector, is connected and fixed.
The making of this split type vertical roll grinder mill is not subject to the restriction of casting ability, processing conditions, has reduced the requirement to the rough-cast tonnage, reduces the cast distortion probability of heavy castings, is convenient to processing and assembling, convenient transportation.
As preferably: two mill splits that form the mill main body are respectively upper millstone and lower millstone, and the two junction connects by the connecting bolt along its circumference uniform distribution.
As preferably: the bearing pin radially arranged is equipped with in the junction of upper millstone and lower millstone along its circumferencial direction.
The accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: upper millstone 1, alignment pin 2, connecting bolt 3, lower millstone 4.
The specific embodiment
Below in conjunction with drawings and Examples to this novel being described further.
This vertical roll grinder mill is comprised of upper millstone 1 and the lower millstone 4 that independent casting forms up and down, and two mill splits are cast respectively, processed.Referring to accompanying drawing 1, the junction of upper millstone 1 and lower millstone 4 is designed with the positioning spigot face, and connect by the connecting bolt 3 along this faying face circumference uniform distribution, in addition, along its circumferencial direction, the alignment pin 2 radially arranged also is housed in this junction, for location, rear whole all the other fitted positions of processing have been assembled.
Claims (3)
1. a vertical roll grinder mill, comprise the mill main body, it is characterized in that, the mill split that described mill body is formed by upper and lower two independent castings forms, and between two mill splits, by connector, is connected and fixed.
2. vertical roll grinder mill according to claim 1, is characterized in that, two mill splits that form the mill main body are respectively upper millstone and lower millstone, and the two junction connects by the connecting bolt along its circumference uniform distribution.
3. vertical roll grinder mill according to claim 1, is characterized in that, the bearing pin radially arranged is equipped with in the junction of upper millstone and lower millstone along its circumferencial direction.
