Description
Technical field
The present invention relates to crushing, grinding, mechanical force activating, mechanical force and chemical and mechanical alloy manufacture field field,
In particular to a kind of planetary 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.
