The discharge port device is reasonable in structural design, can be used for automatic classification and sand returning, and replaces conventional classification equipment; the production cost is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of ball mill discharging mouth device, belongs to ball mill technical field of structures.
Background technology
At present, existing ball mill discharging mouth only plays discharge effect, there is no the effect of classification and sand return, must coordinate the classifying equipoments such as spiral classifier or hydrocyclone could arrive classification and sand return effect.Mainly there is following shortcoming: 1, during closed circuit grinding, because classifying equipoments such as adopting spiral classifier or hydrocyclone has increased production cost, comprising: equipment purchase, maintenance, floor space, capital construction, the electricity charge, depreciation, the expense such as artificial; 2, during open-circuit grinding, owing to not using the classifying equipoments such as spiral classifier or hydrocyclone, make grinding particle size wayward, rough cannot returning, causes next ore dressing effect bad, and wastes mine resources; 3, closed circuit or open-circuit grinding no matter, enters in next stage equipment if be mingled with ironware, steel ball or other foreign material in ball mill discharging, makes next stage equipment produce fault, causes the serious consequences such as maintenance, stopping production, thereby drops into a large amount of human and material resources and financial resources.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design is provided, and can realize automatic classification and sand return, substitutes traditional classifying equipoment, reduce production costs, and the ball mill discharging mouth device of enhancing productivity.
The utility model is achieved through the following technical solutions:
Ball mill discharging mouth device, its special character is to comprise the clasfficiator 2 connecting with ball mill discharging mouth 1, clasfficiator 2 comprises that part stretches into the sand returning machine 3 of discharging opening 1 inside, between the inwall of the outer wall of sand returning machine 3 and discharging opening 1, there is interval, sand returning machine 3 is open column shape, load displacing screw 5 for delivery of ore pulp is installed on the outer wall of the remainder of sand returning machine 3, the outer cup of load displacing screw is provided with for leaching the screen cloth 6 in thin ore deposit, and the inside of sand returning machine 3 is provided with for by the rough returning charge spiral 4 being recycled in ball mill;
The outside of described discharging opening 1 is provided with crusher discharge end cover 7, is provided with for fixedly base bearing 9 and the main box seat 8 of sand returning machine 3 on crusher discharge end cover 7.
Ball mill discharging mouth device of the present utility model, reasonable in design, ore pulp in ball mill is expelled in screen cloth by the interval between sand returning machine outer wall and the inwall of discharging opening, discharge by screen cloth in thin ore deposit, roughly by load displacing screw, drain into end and dig spoon place, dig spoon and will be rough under the rotary action of ball mill dig to sand returning machine inside, by the returning charge spiral rotary in sand returning machine to ore grinding again in ball mill barrel; The utlity model has following beneficial effect: 1, can independently complete the task of classification and sand return, replace traditional classifying equipoment, save floor space, reduce some unnecessary investments and later stage expense; 2, easy to the control ratio tradition classifying equipoment of grinding particle size, only need to change the screen cloth on clasfficiator surface, can reach the object of controlling grinding particle size; 3, due to clasfficiator surface parcel screen cloth, the ironware, steel ball or other foreign material that in ball mill discharging, are mingled with can not be entered in next stage equipment, effectively protected next stage equipment, reduced maintenance, stopping production, thereby saved a large amount of human and material resources and financial resources; 4, manufacturing cost is lower, has reduced the maintenance cost in later stage.During maintenance, only the screw of junction need be unclamped and can pull down, replace with new classification sand returning machine; 5, the transformation of old ball mill is very easy to, only original discharging opening need be pulled down and installed classification sand returning machine; 6, this equipment can be widely used in the ore dressing plants such as iron ore, gold mine, copper mine, at part iron ore, gold mine, selects factory's test, has obtained good effect, the satisfactory requirement that has reached user.
Accompanying drawing explanation
Fig. 1: the structural representation of ball mill discharging mouth device of the present utility model;
Fig. 2: the installation diagram of ball mill discharging mouth device of the present utility model and ball mill;
The A of Fig. 3: Fig. 2 is to perspective view.
The specific embodiment
Below with reference to accompanying drawing, provide the specific embodiment of the present utility model, be used for the utility model to be described further.
The ball mill discharging mouth device of the present embodiment, with reference to accompanying drawing 1-3, comprise the clasfficiator 2 connecting with ball mill discharging mouth 1, clasfficiator 2 comprises that part stretches into the sand returning machine 3 of discharging opening 1 inside, between the inwall of the outer wall of sand returning machine 3 and discharging opening 1, there is interval, sand returning machine 3 is open column shape, load displacing screw 5 for delivery of ore pulp is installed on the outer wall of the remainder of sand returning machine 3, the outer cup of load displacing screw is provided with for leaching the screen cloth 6 in thin ore deposit, and the inside of sand returning machine 3 is provided with for by the rough returning charge spiral 4 being recycled in ball mill; The outside of discharging opening 1 is provided with crusher discharge end cover 7, is provided with for fixedly base bearing 9 and the main box seat 8 of sand returning machine 3 on crusher discharge end cover 7.
Operation principle: ore pulp flows into clasfficiator 2 by discharging opening 1, the screen cloth 6 that meets ore dressing requirement order number at clasfficiator 2 surface parcels, meeting the requirements of ore flows in next stage equipment through screen cloth 6, do not meet the requirements of rough be graded the load displacing screw 5 arranging in device be threaded to end dig spoon 10 places, dig spoon 23 digs to sand returning machine 3 rough under the rotary action of ball mill, by the returning charge spiral 4 in sand returning machine 3, be threaded in ball mill barrel ore grinding again, so circulation makes ball mill classification sand returning machine complete the task of classification and sand return.
Advantage of the present utility model and effect:
