Description
Technical field
The utility model belongs to grinding attachment technical field, is specifically related to a kind of cylindrical ball mill.
Background technology
Current industrial conventional ball mill is as the grinding mechanism of ore reduction; When using ball mill, to need the rotational speed regulation of tank body in ball mill at certain rotating speed to ensure that inner abrasive media is in leaving state; This state and the abrasive media of leaving moves upward after certain altitude with inner tank wall and falls with parabolical track, finally pounds to material, and then realizes grinding of material.But, the wearability of the material of the liner plate selected, toughness is inadequate, and can make in process of lapping, liner plate is subject to the impact of abrasive media and causes cracked breakage, is mixed into the quality affecting ore materials in ore powder, and changes comparatively difficulty at liner plate in inner barrel; In addition, process of lapping abrasive media creates larger vibrations in the mode that cylinder inboard wall parabolically impacts downwards, and for span and all larger ball mill of stand under load, during long-term grinding, to occur to a certain extent bending for cylindrical shell.
In addition, existing babbit slip base bearing installs comparatively difficulty, and the error easily produced in the manufacture and assembling process of machine, comparatively be difficult to ensure and demonstrate,prove concentricity accurately, when grinding for a long time, high vibration degree makes axle center degrees of offset more greatly, and main shaft bearing portion is more easily damaged phenomenon.
Summary of the invention
The purpose of this utility model is to provide a kind of cylindrical ball mill, by repacking cylindrical shell, liner plate, main shaft bearing portion, make cylindrical ball mill under the work of long-term high strength, can the prolonged mechanical life-span, and the structure of its main shaft bearing portion, simpler relative to existing babbit slip base bearing, and more durable.
For achieving the above object, the utility model adopts following technological means to be implemented:
A kind of cylindrical ball mill, comprise driving section, cylindrical shell, end cap, main shaft bearing portion, feeder, discharging portion, frame, wherein, described cylindrical shell is that thickness 30-50mm Plate Welding is made, cylindrical shell has manhole, cylindrical shell and cover internal lay successively in the liner plate of chromium alloyed steel, potassium steel in carbon; The quill shaft of main shaft bearing portion is fitted with the cylinder roller bearing that outer ring has opening, the lubricating cup of open communication main shaft bearing portion, and described cylinder roller bearing is arranged on bearing block, and described bearing block both sides all have flange; Be parallel on the direction in cylindrical shell axle center, be symmetrically arranged with the otch that several are corresponding between flange with cylinder roller bearing outer ring, in otch, correspondence is provided with air compressing spring; Described driving section is connected by the drive pinion of the decelerator that transmission gear wheel is arranged with its side, and decelerator is by shaft coupling connection for transmission motor.
Preferably, described cylinder roller bearing is aligning cylinder roller bearing.
Further, described cylinder internal diameter is 1500-1800mm, and cylindrical shell effective length is 5000-5500mm.
Further, the driving motor of described driving motor to be driving motor be 100-150kW.
Further, described transmission gear wheel is positioned at the junction of cylindrical shell and end cap.
Further, described drive pinion and the shaft coupling of decelerator are positioned at same axis, and drive pinion engages the line in position and cylindrical shell axle center with transmission gear wheel, are 15 °-20 ° with the angle of horizontal plane.
Further, described drive pinion flange and transmission gear wheel assembly.
Further, described driving section also has air clutch, and described air clutch is connected with driving motor with decelerator by shaft coupling.
The utility model at least has the following advantages:
1. by changing the structure of main shaft bearing portion, adopting cylinder roller bearing to be fitted to outside quill shaft, can directly be installed by the mode of lifting to bearing block; Be parallel on the direction in cylindrical shell axle center, the otch that several are corresponding is symmetrically arranged with between flange with cylinder roller bearing, in otch, correspondence is provided with air compressing spring, because the vertical flexibility of air spring is large, cylindrical shell can be made greatly to reduce in axis direction skew; Under the machinery restriction of otch-air compressing spring-otch, and utilize the cooperation of multiple air spring, the transverse elasticity of air spring is more balanced relative to other stiffness springs, greatly reduces the axle center skew of cylindrical shell; And air spring has good absorbing high-frequency vibration and soundproof effect, can reduce noise to a certain extent.
2. by changing the structure of base bearing, and adopt the steel plate of suitable thickness to make cylindrical shell, internal diameter, the effective length of cylindrical shell can expand further, can carry more abrasive media and material; The liner plate of chromium alloyed steel in carbon, potassium steel is used to lay cylindrical shell and cover internal successively, can be cost-saving and reduce the spoilage of liner plate, by promoting amount of grinding and reducing maintenance time, in many aspects, effectively improve the grinding efficiency of material.
3. the starting process of ball mill is usually longer, the ball mill barrel increased to make own wt starts from inactive state, reach effective running status, the shaft coupling of drive pinion and decelerator is positioned at same axis, and make the line in drive pinion axle center and cylindrical shell axle center, horizontal by the angle of 15 °-20 °, the radial load of the binding site of transmission gear wheel and drive pinion and tangential force active force in the horizontal direction, less relative to the active force of vertical direction, reduce when changing running status into from inactive state, the initial moment that required driving motor provides.
4. preferred, be connected by air clutch between shaft coupling with driving motor, relative to the connected mode using driving motor-shaft coupling-ball mill across-the-line starting, the connected mode that driving motor-shaft coupling-pneumatic clutch-shaft coupling-ball mill starts at times, driving motor starting under no load drives shaft coupling, then to pneumatic clutch inflation, thus primer bulb grinding machine, the load to electrical network when ball mill starts can be reduced, extend the life-span of driving motor.
