A kind of planet mill tube of side discharging ball mill
Technical field
The utility model relates to crush, grind, mechanical force activating, mechanical force and chemical and mechanical alloy manufacture field neck
Domain, in particular to a kind of planet mill tube of side discharging ball mill.
Background technique
Ball mill has had more than 100 years history as traditional milling equipment.It refines system as by solid material
The important equipment of powder is widely used in the departments such as metallurgy, chemical industry, cement, ceramics, building, electric power, medicine and national defense industry.
Ore dressing department especially in metallurgical industry, grinding operation are even more to have highly important status.
Milling barrel of planetary ball mill both can be horizontally mounted or be vertically mounted on public turntable.The main distinction of the two
It is that the motion mode of mill tube is different.The cylinder of general milling machine is only around fixed center axis rotation, and planet mill tube is complexity
Plane motion, on the one hand, motor drives the rotation of public turntable, and it is at this time " revolution " that mill tube mounted thereto, which rotates with it,
Transport motion;On the other hand, due to the effect of gear or V -- belt Drive, mill tube is also around the central axis of itself " rotation " opposite fortune
It is dynamic.This existing revolution of mill tube has the plane motion of rotation, referred to as planetary motion again.The planetary motion of mill tube is planet ball
Grinding machine is different from the basic sign of general milling machine.It is considered as the combination of a kind of general milling machine and centrifugal ball mill and
A kind of new architecture to grow up.
Planetary high-energy ball mill can crush material, be ground, be widely used in metallurgy, mineral products, chemical industry, medicine,
The fields such as geology.Planetary ball mill is equipped with multiple ball grinders on same spindle turntable, and each ball grinder is in addition to around main shaft
Rotation, that is, planetary motion are also done while revolution.Other opposite ball mills have higher impact force and hit frequency
Rate preferably can realize broken and welding to powder, be the important equipment of mechanical alloying method in material preparation, material preparation
Process belongs to powder metallurgy under nonequilibrium state, using high-energy impact prolonged between material, abrading-ball and ball grinder, grinds
Pressure makes material repeated deformation, cold welding, broken, refinement, constantly exposes fresh surface, make each element atom phase counterdiffusion
Or solid-state reaction occurs, to realize the complicated physical and chemical process of Elements Atom grade alloying.
Planet mill tube is horizontal to be mounted on the traffic cycle placed perpendicular to ground level, when operation, planet mill tube not only this
Body rotation will also follow traffic cycle to revolve, and form planetary motion.During the motion, the bottom surface that ball grinder is not fixed,
Abrading-ball and the abrasive material collective effect by revolution centrifugal force, rotation centrifugal force and gravity in perpendicular in mill tube.Machine rotation
When turning, the size of each point institute stress and direction are all constantly changing in tank so that abrading-ball and abrasive material in running at high speed mutually it
Between fierce collision, squeeze, substantially increase grinding efficiency and grinding effect.Especially ball grinder is in horizontal crouch and puts mode, and
Due to rotation, the bottom surface that do not fix avoids the knot bottom phenomenon of a part of raw material.
In recent years, since energy expenditure increases, the decline of the grade of ore, reduces construction investment and producing cost is the world
The serious problem that various countries' mine faces is the main tendency of modern dressing plant's construction, ball using high-efficiency large equipment
The enlargement of grinding machine and reduction vibration and noise are defects of the existing technology.
Disclosed above- mentioned information are used only for enhancing the understanding to the utility model background in the background section, therefore
It may be comprising not constituting the information of the prior art known to a person of ordinary skill in the art in home.
Utility model content
In view of this, the shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts, a kind of side is provided and pellet
The planet mill tube of grinding machine can significantly improve the service life of crushing efficiency, discharging efficiency and device.
To achieve the above object, the planet mill tube of discharging ball mill in side provided by the utility model includes:
Connecting shaft is connect with the sun gear of ball mill, and planet mill tube is revolved with sun gear, while being carried out certainly
Turn.
Mill tube ontology, mill tube ontology include the chamber that gathers materials for the grinding chamber of ball milling and for collecting the material after ball milling,
The side wall for chamber radial direction of gathering materials is equipped with relief hole.
Cover board is detachably set to mill tube bodies top.
Liner plate, liner plate are made of anti-abrasive material, are set on grinding cavity wall, lining of the grinding chamber close to the chamber side that gathers materials
Slit is provided on plate.
Further, the liner plate is removably mounted on grinding cavity wall;Backing surface has bulge-structure.Liner plate
On slit can be one or multiple.
Liner plate can be integrated formed structure, be also possible to be spliced by muti-piece liner plate, the liner plate is detachably installed
In grinding cavity wall.
When having multiple slits on liner plate, the slit is radially distributed from less to more, by slot number at subcircular
Few, slot number remoter from the center of circle is more.
The liner plate includes the side plate for being set to grinding chamber side wall, the bottom plate for being set to grinding chamber bottom surface and is set to cover board
On top plate, multiple slits are provided on bottom plate, space between the side plate, bottom plate and top plate forms grinding chamber
Side plate, bottom plate and top plate in grinding chamber all can be integrally formed, and can also have muti-piece.
For the dynamic balancing for keeping planet mill tube revolution and rotation, the connecting shaft is hollow structure, can be reduced significantly altogether
Vibration.
It is provided with driving member in the connecting shaft, driving member is connected cooperation with the central axis of sun gear, enables connecting shaft
Enough rotations.Meanwhile the kind of drive of the driving member can be Synchronous Transmission or differential gearing.
The utility model has the beneficial effects that
The planet mill tube of the side discharging ball mill of the utility model uses the discharge method of side discharging, avoids entire connection
Axis penetrates through and carries material, can rotate more stable, greatly reduces noise and vibration, while can go out by connecting negative pressure
Expect that device realizes that continuous discharge, material are not necessarily to discharge more efficient by longer tapping channel.
