Abstract

The utility model relates to a ball mill used for milling material. Except that the utility model is provided with a motor, a speed reducer, a roller, a charging spiral barrel, a discharging spiral barrel, a material lifting board and a roller gearwheel, the roller is also provided with a charging spiral barrel, a discharging spiral barrel, and a material lifting board which are used for accommodating the reversal work of the ball mill and are provided with spiral ribbed plates in opposite directions. Reverse rotation is realized, the problems of replacing accessories such as the gearwheel, pinions, the gear of the speed reducer, etc. in an overhaul after the long-term use and abrasion of the ball mill can be solved, the service life of the accessories can be extended by one time, and man-hour and maintenance cost can be saved.

Description

Bowl mill

The utility model relates to a kind of ball mill, is used for the machinery of grinding material, especially for the ball mill of building material industry.

The ball mill of prior art, use through long-term, the reductor of running part, pinion, cylinder discharge end gear wheel, can heavy wear, when these parts time spent again, all adopts the way of changing accessory or replacing ball mill and reductor at present, this way will be through dismounting, installation, debugging, both time-consuming, change a lot of funds of expense again, also influence is produced.Especially change gear wheel, difficulty is bigger.If adopt the ball mill reversal process, make the reverse side engagement of gear teeth face, can prolong the service life of accessories such as gear wheel greatly, delay the replacement cycle.But, also there be spiral gusset, the incompatible problem of lifting blade spiral gusset of charging and discharging spiral tube in this in the other direction except needs motor wiring commutation, liner plate are laid.At present, the precedent of still not having this method of employing.

Purpose of design of the present utility model is to overcome weak point of the prior art, and provide a kind of solve ball mill and use wearing and tearing for a long time after, need overhaul, change the problem of large and small gear, reductor etc., be convenient to realize the ball mill counter-rotating, prolong the service life of accessories such as gear wheel, delay the dual-purpose ball mill of rotating of replacement cycle.

Purpose of design of the present utility model can reach by following measure:

Motor is being arranged, reductor, cylinder 4, the feed auger tube 5 of cylinder and discharging spiral tube 1, advance, discharging spiral tube 5, the spiral gusset is arranged in 1, in cylinder 4, side near discharging spiral tube 1 has the lifting blade of installing side by side 2,6, lifting blade 2, the spiral gusset is arranged on 6, the cylinder discharge end has gear wheel 3, have on the cylinder inner peripheral surface in the ball mill of the liner plate 10 that is screwed, cylinder 4 has to adapting to ball mill counter-rotating usefulness, the spiral of its gusset advances for the opposite direction spiral, discharging spiral tube 9,7, with and the spiral of gusset serve as spiral in the other direction, near discharging spiral tube 1 one sides, the lifting blade 8 of An Zhuaning side by side, 11.

The utility model compared with prior art has following advantage:

1. be convenient to ball mill and adopt reversal process, after the solution ball mill uses wearing and tearing for a long time, need overhaul to change the problem of accessories such as large and small gear, reductor, make prolong one times the service life of accessories such as large and small gear.Reduce to change accessory such as large and small gear or change expending of man-hour that ball mill caused, fund, reduce producing influence.

2. simple, remarkable in economical benefits.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1,2 illustrates existing ball mill except that major parts of part such as motor, reductor, pinions--cylinder 4 with and on the structure of accessory, the structure when the dual-purpose ball mill of the utility model rotating is just just changeing.One end of cylinder 4 has discharging spiral tube 1, its other end is a feed auger tube 5, in the charging and discharging spiral tube 5,1 the right-hand screw gusset is arranged, present product generally all is the right-hand screw gusset, the lifting blade 6,2 that in cylinder 4, near a side of discharging spiral tube 1, band spiral gusset is arranged, install side by side, the cylinder discharge end has gear wheel 3, and the liner plate 10 that is screwed is arranged on the cylinder inner peripheral surface.Be to adapt to ball mill counter-rotating requirements of one's work, cylinder 4 need have spiral gusset in the other direction in it, i.e. the charging and discharging spiral tube 9,7 of left-hand screw gusset, with and the spiral of gusset become the lifting blade 11,8 of rightabout spiral with former lifting blade.

The cylinder that Fig. 3,4 shows the utility model ball mill with and go up the structure of accessory when the counter-rotating work.The charging and discharging spiral tube 9,7 that the left-hand screw gusset is arranged in cylinder 4 has been loaded onto, lifting blade are in the other direction spiral gusset, the lifting blade 11,8 installed side by side.For adapting to the needs of ball mill counter-rotating, the liner plate 10 in the cylinder 4 will be laid again by original rightabout, rolls in the other direction to adapt to steel ball.The processing of charging and discharging spiral tube 9,7 and former charging and discharging spiral tube 5,1 are basic identical, all are to use welded steel plate, and different only is that the gusset spiral is changed into left-hand screw by right-hand screw.The also available former spiral tube transformation of the way.Lifting blade 11,8 also only is that the spiral gusset is made into rightabout.

Fig. 5,6,7 shows existing ball mill, different near the lifting blade 6 of discharging spiral tube 1 and opposite direction spiral gusset lifting blade 11 structures.

Fig. 8,9,10 shows existing ball mill, different near the lifting blade 2 of discharging spiral tube 1 and opposite direction spiral gusset lifting blade 8 structures.
