Abstract
A kind of barrel lining board which can make the ball mill more effectively crush, crush and grind the material, it can make the material and the grinding body naturally graded; according to the device, the Archimedes spiral grooves are used for lifting materials in the circumferential direction, and the helicoids are used for natural grading in the axial direction, so that the grinding dead angle in the mill is reduced, the grinding area is increased, and the working efficiency of the ball mill is improved.
Description
The utility model relates to a kind of ball mill liner plate, is specially adapted to produce the cement ball mill.
Known ball mill liner plate has flat liner plate, protruding liner plate, ladder lining board and trench liner etc.Flat liner plate is to promote material by static friction, and grainding capacity is good, but grindability is poor; Protruding liner plate promotes material by boss, and grindability is good, but grainding capacity is poor; The ladder lining board working face is the Archimedes spiral type, the drag coefficient of material is equated, hoisting depth even to, improved milling capacity, but the grinding dead angle arranged between the liner plate, influenced mill output; Common trench liner highly reduces the band material, thereby has influenced grindability because abrasive body breaks away from the angle increase.
The purpose of this utility model provides a kind of liner plate, and it can carry out more effective fragmentation, pulverizing and grinding to material, increases work efficiency and grainding capacity, cuts down the consumption of energy.
The purpose of this utility model is achieved in that the liner plate working face circumferentially adopts the Archimedes spiral type, and the working face rear portion is curved, and the working face top is the bidirectional screw face, and top longitudinal center line lead angle is 5 to 30 degree.The liner plate working face has circumferentially adopted Archimedes spiral type and rear portion curved, is to grind the dead angle in order to remove, and makes effective line segment steepening of Archimedes spiral, like this, has improved the hoisting power to material and abrasive body, has increased effective milling area; Axially adopt the bidirectional screw face to be used in combination with groove, increased grading effect, ventilation in the grinding machine makes material be flowed to low material level by high charge level, material is moving to the mill wake flow by bistrique, big material and abrasive body under action of centrifugal force many segregations in cylindrical shell, the axial screw classification makes to flow to and slows down, and goes into the nature classification, and the obvious segmentation of fragmentation, pulverizing and grinding in the mill is carried out.
Below in conjunction with accompanying drawing the utility model is described further.
Accompanying drawing 1 is a three-view diagram of the present utility model.
Among Fig. 1: 1, liner plate working face front portion
2, liner plate working face top
3, liner plate working face rear portion
4, the circumferential grooves of liner plate
5, liner plate installed surface
6, the liner plate installed surface alleviates groove
Liner plate working face front portion is the Archimedes spiral type, and liner plate working face top is the bidirectional screw face, and liner plate working face rear portion is curved.
Owing to adopted such scheme, overcome the shortcoming of flat liner plate, protruding liner plate, ladder lining board and common trench liner, fragmentation, pulverizing and the grainding capacity of ball mill all are improved.
Claims (4)
1, bipitch staged trench liner plate is characterized in that: (1) circumferentially is the Archimedes spiral type at the working face of liner plate; (2), liner plate axially is classification bidirectional screw face; (3), the working face rear portion is curved; (4), liner plate assembled arrangement in ball mill, row groove circumferentially.
2, according to the described structure of claim 1, its feature circumferentially is half garden arc of the curved and middle usefulness of Archimedes spiral type and rear portion at working face and connects.
3, according to the described structure of claim 1, it is characterized by the working face top is the bidirectional screw face, and top longitudinal center line lead angle is 5 to 30 degree.
4, according to claim 1,2,3 described structures, it is characterized in that liner plate assembled arrangement in ball mill, form circumferential grooves, groove centre-to-centre spacing equals average abrasive body diameter and adds 2 to 15 millimeters.
