Description
Technical field
The present invention relates to grinding device technical field, especially a kind of cement grog grinding implements equipment and its stirring dress
It sets.
Background technique
High energy ball mill is broken and grinding process core equipment, industrially leads tumbling ball mill processing to be used
Amount is big, but it is there are critical speed, and collision energy is smaller when ball milling.Stirring ball mill shell portion is fixed, blender companion
Main shaft is rotate together at high speed, and is driven the intracorporal abrasive media of cylinder to move together under the action of frictional force and centrifugal force, is made medium
Between, fierce and frequent collision, shearing and rubbing action occur between medium and wall surface, to cause the broken and solution of material
From.There is no revolving speeds to limit in stirring ball mill principle, and collision energy can achieve very high values when ball milling, realizes that high-energy is close
Degree input.
Stirring ball mill can be divided into vertical and two kinds horizontal according to agitating shaft mounting means, can be divided again according to grinding process
It is two kinds of dry and wet.It is vertical compared with horizontal, vertical agitating shaft using suspension installation, in mechanical milling process agitating shaft by
Dynamic impulsion effect swings agitating shaft excessive, works long hours, and is easy to appear card machine phenomenon and bearing seal failure.Dry method
Compared with wet process, wet process technique process is complicated, subsequent to carry out dehydration and drying and processing, finished product fabrication cycle are long.
A kind of stirring for mill-drying or non-dry substance according to disclosed in Chinese invention patent CN103567028B
Formula ball mill is equipped with grinding container, and agitating shaft extends about in grinding container center or center, multiple grinding element settings
On the agitating shaft.Fluid channel is arranged in stirring axis center in the stirring ball mill, is directed fluid into using fluid channel
It is connected to the spatial neighborhood of the last one grinding element of exit region upstream, fluid is with 0-50m/s speed in grinding container
It is mobile.The stirring ball mill is mainly applicable in wet grinding, and stream is radially through separator to separation of material and grinding
Medium, material are easy to accumulate at separator.Fluid is spurted by the tap that exit region upstream is arranged in agitating shaft
Grinding container, material simultaneously flow between exit region upstream, separator and outlet, optimize pumped (conveying) medium in grinding container
Flowing, alleviate putty problem, but consume energy it is higher.
According to disclosed in Chinese invention patent CN104053506A it is a kind of run stirring-type ball milling method and execute the party
The stirring ball mill of method, wherein separation system includes the stationary screen with free hole face, which is constructed so as to pass through
Separation system and products export leave the gas of agitation grinder by speed be about 10m/s to 30m/s, preferably 15m/s extremely
25m/s.The stirring ball mill is equally mainly applicable in wet grinding, drives the stream with viscosity to do by agitating shaft rotation
Grinding movement, to carry out the grinding of material under the high revolving speed of high fill-ratio.The discharge port of the stirring ball mill is arranged in cylinder
Body end center is equally unfavorable for material and is normally discharged using air swept mill form discharge, is consumed energy higher.
A kind of horizontal type dry internal classification agitator mill according to disclosed in Chinese invention patent CN202447150U, including cylinder
Body, agitating shaft, drive system, charging flapper, air cooling system, hierarchy system and base, the agitating shaft installation in cylinder,
End connects drive system, and cylinder is mounted on base, and charging flapper is mounted on cylinder one end top and connects with feed inlet, gas
Device for cooling is mounted in cylinder, and hierarchy system is mounted in cylinder upper part discharge port.The horizontal type dry internal classification agitator mill into
Material mouth is arranged on cylinder top, is unfavorable for normally being fed under high revolving speed high fill-ratio；Its agitating shaft is by main shaft and stirring
Disk or blade composition, are easy to appear the area Si Liao, especially under conditions of pack completeness is higher than 32%, abrasive media and material accumulation
In cylinder, agitator disk or lamina idle-run, abrasive media and material can not carry out effectively grinding movement.
In wet grinding, abrasive media and material form the stream with certain viscosity, the stream with viscosity
It is easily taken up by blender and does grinding movement in stir chamber；And in dry method grinding, dry abrasive media and material are formed
Stream, especially positioned at stir chamber middle and lower part stream be easy be detained and generate the area Si Liao.Under the conditions of the low filling rate of the slow-speed of revolution,
The area Si Liao that this horizontal type dry-process grinding generates is relatively fewer, but under the high speed conditions of high fill-ratio, blender will appear sternly
The idle running problem of weight can not be normally carried out grinding work.
Summary of the invention
It is an object of the invention to: aiming at the problem that existing horizontal ball mill is not suitable for clinker dry method grinding, especially
It is that existing horizontal ball mill the problem of a large amount of areas Si Liao occurs in the case where height fills high speed conditions, it is ripe that the present invention provides a kind of cement
