Description
Technical field
The present invention relates to the attrition process field of granular materials, in particular to the ball mill of a kind of refractory material and its use
Method.
Background technique
Ball mill is the key equipment that material is broken and then is crushed.It, which is commonly applied to refractory material etc., to grind
The dry type or wet type grinding of property material, have many advantages, such as that performance is more stable, fineness of grind is high.Ball mill is by horizontal cylinder
Body, input and output material hollow shaft and mill first class sections composition, cylinder are long cylinder, and cylinder is provided with abrasive body, and cylinder is steel plate manufacture,
It is fixed by steel liner plate and cylinder, as shown in figure 4, abrasive body is generally steel ball, and is filled by different-diameter and certain proportion
Enter in inner cylinder.It is selected according to the granularity of grinding material, material is packed into cylinder by feeding of ball mill end hollow shaft, works as ball milling
When machine drum body rotates, abrasive body is attached to it on shell liner by cylinder due to the effect of inertia, centrifugal force and frictional force
Take away, when being brought to certain height, due to itself gravity and left, the grinding body image projectile of whereabouts
Equally the intracorporal material of cylinder is smashed.Material by feeding device through pan feeding hollow shaft spiral evenly into the first storehouse of grinding machine,
There are ladder lining board or corrugated liner, built-in various specifications steel ball in the storehouse, barrel body rotation generates centrifugal force and take steel ball centainly to
It is fallen after height, bang and abrasive action is generated to material.
The main function of steel ball is to carry out impact grinding to material, while also functioning to certain abrasive action in ball mill.
Therefore, steel ball carries out the purpose of gradation, seeks to the requirement for meeting these two aspects.The quality of crushing effect is directly to mill efficiency
It has an impact, and finally influences ball mill output, crushing can be reached and require the gradation for depending on steel ball whether reasonable, it is main to wrap
Include steel ball size, sphere diameter series, various specifications ball proportion etc..
There is following defects for ball mill used at present: when inner cylinder rotation, the movement of steel ball has randomness, distribution
Unevenly, the effect of grinding material is influenced；Further, since steel ball size, sphere diameter series, various specifications ball proportion do not conform to
Reason, is easy to cause abrasive grains degree uneven, grinding efficiency, grinding effect are bad.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
Summary of the invention
The object of the present invention is to provide a kind of ball mill of refractory material and its application methods, have and preferably grind
Effect is ground, production application demand can be preferably met.
The present invention is achieved by the following technical solutions:
A kind of ball mill of refractory material, comprising:
Pedestal, the pedestal are set on horizontal platform；
Body is ground, which includes outer cylinder and inner cylinder；Feed inlet is equipped at the top of the outer cylinder, bottom is equipped with discharging
Mouthful；The inner cylinder is connect with a drive member, which drives the inner cylinder rotation, is equipped with multiple steel in the inner cylinder
Ball, and the inner wall of inner cylinder is equipped with multiple grinding columns for protruding from inner wall, and the grinding column is distributed in the inner wall of the inner cylinder
On；There are gaps between the outer cylinder and inner cylinder to form interlayer, is filled with cooling medium in the interlayer；And
Lifting device, which is set to the weight that grinding body is supported between grinding body and pedestal, described
There are two lifting devices and the left and right ends of the grinding body are arranged in, by the lifting of two lifting devices to regulate and control
State the horizontal tilt degree of grinding body.
The specification of the multiple grinding column is all the same.
The specification of the grinding column has multiple, and height is distributed as 30-60mm, diameter 20-50mm.
There are four specifications for the grinding column, are respectively as follows: height 30mm, diameter 20mm, height 40mm, diameter 32mm, height
50mm, diameter 40mm, height 60mm, diameter 50mm.
Further, specification is height 30mm, the grinding column quantity of diameter 20mm accounts for the 12% of grinding column sum, and specification is
Height 40mm, diameter 32mm grinding column quantity account for grinding column sum 25%, specification be height 50mm, diameter 40mm grinding
Column quantity accounts for the 40% of grinding column sum, and specification is height 60mm, the grinding column quantity of diameter 50mm accounts for grinding column sum
23%.
The grinding column is staggeredly uniformly distributed on inner cylinder inner wall.
Further, the lifting device is raise-lower hydraulic cylinder structure.
The horizontal tilt degree of the grinding body is 0~80 °, since gradient is bigger, is fallen convenient for material is cleaner
Out；It avoids causing the material for making different cultivars when grinding different material next time to keep material component mixed due to mixing because of material remnant
It is miscellaneous, the final property for influencing product.
A method of using ball mill, the ball mill includes: pedestal, which is set on horizontal platform；Grinding
Body, the grinding body include outer cylinder and inner cylinder；Feed inlet is equipped at the top of the outer cylinder, bottom is equipped with discharge port；The inner cylinder
