Abstract
The utility model proposes a kind of ball milling dry mill, comprise warehouse, center, described warehouse front end is provided with charging aperture, described warehouse tail end center is provided with discharge port, described ball milling dry mill charging aperture and discharge port are all widened to 30% of the warehouse diameter of grinding machine, and arrange a variable-frequency governor outside described grinding machine, described variable-frequency governor controls a feed belt, and described feed belt directly stretches into mill feeding mouth; Described ball mill body is outside equipped with a sealing and dustproof cover.The technical program does not use the charging of ball mill original spiral feeding cylinder, so charging aperture can be widened, to improve feed properties further, increases ball mill handling capacity.And the diameter of discharge port can be widened, the overall handling capacity improving grinding machine simultaneously.
Description
Technical field
The utility model relates to mining machinery field, refers to a kind of ball milling dry mill especially.
Background technology
Mine ball milling dry mill is the one of ball mill, is according to one of supporting equipment of the ore dressings such as mine quarrying slab, belongs to grate ball mill.
As shown in Figure 1, the ball milling dry mill discharging part of prior art is generally at the core of grinding machine warehouse afterbody, namely charging aperture is set at grinding machine warehouse front end core, arrange discharge port at warehouse tail end core, its charging aperture and discharge port diameter are limited to and account for less than 15% of grinding machine warehouse diameter.
Wherein, feeding part generally comprises blanking scraper-trough conveyer and spiral feeder, adopts feeding machine by spiral feeder charging.
But the mode of this employing feeding machine spiral charging is according to the charging of grinding machine rotational velocity during charging, there is charging rate slow, handling capacity size cannot adjust the shortcoming of change.
Further, because grinding machine is directly exposed to job site, airborne dust is large, seriously polluted.
Utility model content
In order to solve the problem, the utility model proposes a kind of ball milling dry mill, improve charging and discharging handling capacity.
The technical solution of the utility model is achieved in that
A kind of ball milling dry mill, described ball mill is storehouse formula grinding machine, comprises warehouse, rotating part, base bearing part, feeding part, gear cover part, running part and electric control system;
Center, described warehouse front end is provided with charging aperture, and described warehouse tail end center is provided with discharge port;
Outside described grinding machine, arrange a variable-frequency governor, described variable-frequency governor controls a feed belt, and described feed belt directly stretches into mill feeding mouth, and directly passes into warehouse;
Described ball milling dry mill charging aperture and discharge port all account for 30% of the warehouse diameter of grinding machine.
The technical solution of the utility model utilizes variable-frequency governor can arbitrarily control belt transfer rate, and then regulates charging rate.Adopt this feeding structure directly to mill feeding, make charging rate have adjustability, arbitrarily can control speed, thus effectively control the handling capacity of grinding machine.
And because the technical program does not use the charging of ball mill original spiral feeding cylinder, so charging aperture can be widened, to improve feed properties further, increase ball mill handling capacity.And the diameter of discharge port can be widened, the overall handling capacity improving grinding machine simultaneously.
The technical program changes grinding machine central bore in the past, is enlarged to and accounts for 30% of grinding machine warehouse, improve charging, and strengthen handling capacity, same mill diameter can double output, improves the production capacity of grinding machine, reduces production cost 40%.
As the further improvement to technique scheme, can a sealing and dustproof cover be set outside ball mill body, contaminated solution problem further.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is feeding of ball mill and discharging structure schematic diagram in prior art;
Fig. 2 is the overall structure schematic diagram of the utility model ball mill.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, existing feeding of ball mill, discharging structure are generally at the core of grinding machine warehouse, namely arrange charging aperture at grinding machine warehouse front end core, arrange discharge port at warehouse tail end core, charging aperture and discharge port diameter are limited to and account for less than about 15% of grinding machine warehouse diameter.
Its feeding structure generally comprises spiral feeder, adopts feeding machine by spiral feeder charging, namely with feeding machine, material is sent into feed inlet of globe mill place, makes it be sent in ball mill by spiral-tube spiral according to the rotational velocity of ball mill.
The mode of this employing feeding machine spiral charging is according to the charging of ball mill rotational velocity during charging, and there is charging rate slow, handling capacity size cannot adjust the shortcoming of change.
Further, because ball mill is directly exposed to job site, airborne dust is large, seriously polluted.
The technical solution of the utility model can be improved according to the existing ball mill structure for mine, adopts some New Measure, changes the part its structural design being not suitable for mine use, makes it utilizing status more reasonable, raises the efficiency.
As shown in Figure 2, ball milling dry mill of the present utility model is storehouse formula grinding machine, comprises warehouse, rotating part, base bearing part, feeding part, gear cover part, running part and electric control system;
Center, described warehouse front end is provided with charging aperture, and described warehouse tail end center is provided with discharge port;
Outside described grinding machine, arrange a variable-frequency governor, described variable-frequency governor controls a feed belt, and described feed belt directly stretches into mill feeding mouth, and directly passes into warehouse;
Described ball milling dry mill charging aperture and discharge port all account for 30% of the warehouse diameter of grinding machine.
The technical solution of the utility model utilizes variable-frequency governor can arbitrarily control belt transfer rate, and then regulates charging rate.Adopt this feeding structure directly to mill feeding, make charging rate have adjustability, arbitrarily can control speed, thus effectively control the handling capacity of grinding machine.
And because the technical program does not use the charging of ball mill original spiral feeding cylinder, so the diameter of charging aperture is not by the restriction of spiral feeder, charging aperture can be widened, to improve feed properties further, increase ball mill handling capacity.And broaden the diameter of discharge port, entirety improves the handling capacity of grinding machine simultaneously.
As the further improvement to technique scheme, can a sealing and dustproof cover be set outside ball mill body, contaminated solution problem further.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
