Abstract
The utility model provides a kind of ring roll grinder wear resistance mill, including mill, grinding ring, abrading-ball；The mill is mounted in grinding machine by main shaft, and the grinding ring is fixedly mounted in grinding machine, and the abrading-ball is movably arranged in mill, is equipped with wear-resistant components on the contact surface of the abrading-ball and mill.The utility model grinding machine grinds abrading-ball generation centrifugal force by the ore between abrading-ball and grinding ring by mill rotation; it is wear-resistant ceramic that mill easily-worn position, which installs abrasionproof component; it is that the wear-resisting property of mill greatly improves; and due to the presence of wear-resistant components; the material of mill requires to reduce; the manufacturing cost for reducing mill reduces the dosage of mill and shuts down the data of replacement mill, realizes the double effects of consumption reduction synergy.
Description
Technical field
The utility model relates to a kind of ring roll grinder wear resistance mills.
Background technique
Ore particles are processed into miberal powder by ring roll grinding machine, its working principle is that milling spindle band movable grinding disc, straight pin, mill
Ball, high speed rotation.Because of the loose fit of abrading-ball inner hole and straight pin outer circle, abrading-ball is made to generate centrifugal force, spherical outside surface acts on
The grinding ring Internal Spherical Surface of fixed static, ore particles enter between two spherical surfaces, and by the shock of abrading-ball, rotation is milled into powder.Mill
Ball impact, mill ore particle while, biggish vibration rotation can be generated and rubbed with mill.Though the material of the two is all high alloy
Steel, because the structure of mill needs to consider have certain toughness, hardness is slightly lower, and the abrading-ball scale of construction is big in addition, and revolving speed is high, therefore mill easily quilt
Abrading-ball is ground away.In production process, it has to often shut down replacement mill, cause production cost to increase and drag down production efficiency, tear open
Dress be not easy also bring along security risk.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of ring roll grinder wear resistance mill.
The utility model is achieved by the following technical programs.
A kind of ring roll grinder wear resistance mill provided by the utility model, including mill, grinding ring, abrading-ball；The mill passes through
Main shaft is mounted in grinding machine, and the grinding ring is fixedly mounted in grinding machine, and the abrading-ball is movably arranged in mill, the abrading-ball and
Wear-resistant components are installed on the contact surface of mill.
The mill is mounted on main shaft by flat key.
The mill includes upper millstone and lower millstone, upper millstone and is fixed on lower millstone, upper millstone and lower millstone combination
Side afterwards is machined with notch, and the both ends of notch are machined with pin hole.
The abrading-ball is mounted in notch by straight pin, is fixedly mounted in the pin hole of notch.
The abrading-ball is bead type, and abrading-ball is movably arranged on straight pin, the upper and lower ends burnishing surface of abrading-ball and notch
Upper and lower ends are in close contact.
The wear-resistant components include sheath, and sheath one end is machined with cavity, and cavity upper end is opening, and cavity bottom is machined with
Air hole, cavity is interior to be filled with filler.
The open edge of the sheath is set as groove.
The filler is one of aluminium oxide or zirconium oxide or combinations thereof object.
The utility model has the beneficial effects that: grinding machine makes abrading-ball generate centrifugal force for abrading-ball and grinding ring by abrading-ball rotation
Between ore grind, it is displacement that the abrasionproof component on mill prevents abrading-ball from generating in centrifugal force effect, vibration, right in rotary course
Mill generates abrasion, and since the presence of abrasionproof component, the material of mill require to reduce, reduces mill manufacturing cost,
Reduce the dosage of mill and shut down the data of replacement mill, realizes the double effects of consumption reduction synergy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is partial enlarged view at A in Fig. 1；
In figure: 1- mill, 11- upper millstone, 12- lower millstone, 13- wear-resistant components, 14- notch, 131- sheath, 132- are filled out
Fill object, 133- air hole, 2- grinding ring, 3- abrading-ball, 31- straight pin, 4- main shaft, 41- flat key.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
A kind of ring roll grinder wear resistance mill, including mill 1, grinding ring 2, abrading-ball 3；The mill 1 is mounted on by main shaft 4
In grinding machine, the grinding ring 2 is fixedly mounted in grinding machine, and the abrading-ball 3 is movably arranged in mill 1, the abrading-ball 3 and mill 1
Contact surface on wear-resistant components are installed.Grinding machine is rotated by mill 1 makes mill generate centrifugal force for abrading-ball 3 and grinding ring 2
Ore is ground, and the abrasionproof component on mill prevents abrading-ball from ground in displacement process to mill generation under the action of the centrifugal force, and
Due to the presence of abrasionproof component, the material of mill requires to reduce, and reduces mill manufacturing cost.
The mill 1 is mounted on main shaft 4 by flat key 41.
The mill 1 includes upper millstone 11 and lower millstone 12, upper millstone 11 and is fixed on lower millstone 12, upper millstone 11
Side after combining with lower millstone 12 is machined with notch 14, and the both ends of notch 14 are machined with pin hole.Make the centrifugal force direction of abrading-ball 3
Radially consistent with the inner groovy of grinding ring 2, the abrasive power that the ore inside grinding ring 2 receives is maximum.
The abrading-ball 3 is mounted in notch 14 by straight pin 31, and straight pin 31 is mounted in pin hole.The abrading-ball 3 is
Bead type, abrading-ball 3 are movably arranged on straight pin 31, and the upper and lower ends burnishing surface and the upper and lower ends of notch 14 of abrading-ball 3 are close
Contact.Under the action of not interfering abrading-ball to generate centrifugal force, additionally it is possible to so that abrading-ball is rotated, reduce the abrasion of abrading-ball.
