Description
Technical field
The invention belongs to ball mill technical field, particularly a kind of classifying lining board of ball mill.
Background technology
Ball mill is the key equipment that material is broken and then crushes；Ball mill is by horizontal cylinder, disengaging
Expect hollow shaft and mill first class sections composition, cylinder is long cylinder, is manufactured in cylinder equipped with abrasive body, cylinder for steel plate, there is steel
Liner plate is fixed with cylinder, and abrasive body is generally steel ball, and is fitted into cylinder by different-diameter and certain proportion, and abrasive body also may be used
With steel section；Material is packed by feeding of ball mill end hollow shaft in cylinder, and when ball mill barrel rotates, abrasive body is due to inertia
It is acted on centrifugal force, the effect of frictional force makes it be attached on shell liner and taken away by cylinder, when being brought to certain height
It waits, is left due to the gravity of itself, the grinding body image projectile of whereabouts is equally smashed the material in cylinder；
Ball grinding machine lining board is for protecting cylinder, makes cylinder from abrasive body and material directly impact and friction, while
The motion state of abrasive body can be adjusted using various forms of liner plates, to enhance pulverization of the abrasive body to material, is helped
In the mill efficiency for improving grinding machine, increase yield, reduce metal consumption；When being main to crush, it is desirable that liner plate is to abrasive body
Election ability is stronger；When using fine grinding as it is main when, the protrusion of liner plate is just weak to the election of abrasive body effect with regard to smaller, impact compared with
It is small, and abrasive action is stronger；Existing classifying lining board is typically all to set the inclined-plane of single angle, protrusion or recessed in liner plate ontology
Slot come play the role of adjust abrasive body motion state, the inclined-plane of single angle can only guide the movement of abrasive body single direction；
Protrusion and groove structure then mainly help the election improved to abrasive body and act on, but protrusion and groove structure are complicated, classification lining
Plate processing is more complicated.
Invention content
Goal of the invention：The deficiency that the purpose of the present invention is be directed in current technology provides a kind of classifying lining board of ball mill,
Including liner plate ontology, liner plate ontology is equipped with inclined surface, and inclined surface has along grinding machine axis direction and axis vertical line direction
Gradient automatically by steel ball by the descending arrangement in mill shaft line direction, while has preferable band on ball mill direction of rotation
Expect election effect；
Technical solution：To achieve the above object, the present invention provides a kind of classifying lining board of ball mill, includes liner plate sheet
Body, liner plate ontology are equipped with inclined surface, and inclined surface is gradient along grinding machine axis direction and axis vertical line direction, along grinding machine
High point is located at mill tail direction on axis direction, and high point is located at the direction opposite with grinding machine direction of rotation along axis vertical line direction；
Thus obtained inclined surface high point is located at the combination in above-mentioned two high points direction；
As a kind of improvement of this programme, the liner plate ontology upper inclined surface and horizontal direction angle are 20 ° ~ 45 °；
As a kind of improvement of this programme, the classifying lining board surface is provided with alloy wear-resisting layer；
Advantageous effect：The classifying lining board upper surface of ball mill of the present invention has hangs down along grinding machine axis direction and axis
With gradient inclined surface on line direction；Classifying lining board is of an inclined plane in grinding machine axial slices, and high point is in mill tail, low side direction
Bistrique；Steel ball on classifying lining board inclined-plane, the active force that its classifying lining board being subject in axial slices is given are vertical
With bevel direction, since inclined-plane high point is in mill tail direction, so the active force is biased to bistrique direction；When ball mill rotates, steel ball
Make the partial circumference operation of standard in cylinder, but when steel ball enters and leaves, under the action of above-mentioned active force, steel ball will
It is run to bistrique direction, in this way, all steel balls for being graded liner plate contact pour into bistrique direction one after another, is ground interior space and steel ball
Between frictional force restriction, so as to which steel ball be made in mill to form the low slightly inclined constructional surface of a head height tail；Due to big ball inertia
Bigger than bead, therefore in above-mentioned steel ball banking process, big ball is easier to occupy the point for wanting to occupy, i.e., big ball closer to
Bistrique, bead make way for big ball, it is achieved thereby that the arrangement of steel ball from big to small；
Classifying lining board is vertically with being equally of an inclined plane on the section of grinding machine axial direction, high point is in the negative side of cylinder direction of rotation
Upwards, the steel ball on classifying lining board inclined-plane, the active force that the classifying lining board being subject in axial slices is given are vertical
With bevel direction, due to inclined-plane high point in cylinder direction of rotation in the reverse direction, so the active force is biased to cylinder rotation side
To simultaneously because the presence on inclined-plane, improving the position of steel ball throw point, make steel ball that there is the gravitional force of bigger, during whereabouts
The impact energy of bigger has better crushing effect；
The classifying lining board can improve the position of steel ball throw point, be the impact energy that steel ball has bigger, can have
Effect improves ball mill crushing effect；And under the action of the classifying lining board, steel ball realized in ball mill in an axial direction by greatly to
Small arrangement, material by the different steel ball of diameter crush and grind layer by layer, and evenly, quality is more for obtained diameier
It is high；The classifying lining board is simple in structure, easily manufactured, and surface is provided with alloy wear-resisting layer, can effectively reduce classifying lining board
The abrasion and consumption of itself avoid frequently carrying out the replacement of classifying lining board, reduce time and cost of labor.

Figure, as shown in the figure, the high point of axial vertical line inclined surface 3 is located at the opposite direction in grinding mill barrel direction of rotation, axial vertical line tilts
30 ° of face 3 and horizontal direction angle；
In actual use, bistrique side is partial in axially inclined face 2 to the classifying lining board to steel ball application in grinding machine
To active force, all steel balls for being graded liner plate contact pour into bistrique direction one after another, by grinding friction between interior space and steel ball
The restriction of power, so as to which steel ball in mill be made to form the low slightly inclined constructional surface of a head height tail；Since big ball inertia ratio bead is big,
Therefore in above-mentioned steel ball banking process, big ball is easier to occupy the point for wanting to occupy, i.e., big ball closer to bistrique, bead
Big ball is made way for, it is achieved thereby that the arrangement of steel ball from big to small；Axial vertical line inclined surface 3, which applies steel ball in grinding machine, is biased to cylinder
The active force of body direction of rotation, simultaneously because the presence on inclined-plane, improves the position of steel ball throw point, steel ball is made to have bigger
Gravitional force, the impact energy of bigger during whereabouts, has better crushing effect；
