Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of device that automatically adds milling medium to grinding machine, change traditional overhead traveling crane handling and add ball mode, by steel ball storehouse, fan-shaped hydraulic gate, electronic scale, rubber conveyer and hydraulic push rod are set, realize steel ball auto-continuous addition.
The technical solution adopted in the utility model is: a kind of device that automatically adds milling medium to grinding machine, is characterized in that: comprise and add ball storehouse, add bottom, ball storehouse and be provided with fan-shaped hydraulic gate, hydraulic gate is controlled opening and closing by gate push rod; Add ball storehouse below and be provided with rubber conveyer, add ball storehouse and rubber conveyer intersection is provided with electronic scale; Milling medium enters grinding machine chute through rubber conveyer, and rubber conveyer and grinding machine chute junction are provided with guide baffle plate, and guide baffle plate is controlled its switching by hydraulic push rod.
The described top that adds ball storehouse is cuboid, and bottom is cone.
Described rubber conveyer is frequency conversion corrugated flange blet conveyor.
In the utility model, be provided with fan-shaped hydraulic gate adding ball storehouse bottom, whether unlatching or closing control by hydraulic gate add ball; Rubber conveyer connects the material feeding end of grinding machine, and rubber conveyer is chosen frequency conversion corrugated flange blet conveyor, adds ball speed, and control steel ball additional amount by electronic scale by adjusting the control of rubber conveyer operating frequency, and supporting electronic scale accurately shows the ball amount that adds.
The automatic device that adds milling medium to grinding machine that the utility model provides, the beneficial effect bringing:
(1) change traditional overhead traveling crane handling and add ball mode, by steel ball storehouse, fan-shaped hydraulic gate, electronic scale, rubber conveyer and hydraulic push rod are set, realized the accurate auto-continuous addition of steel ball, optimize different-diameter steel ball matching in grinding machine, improve ore milling product granularity qualification rate and ball mill ore grinding efficiency.
(2) each serial semi-autogenous mill designs separately steel ball storehouse, fan-shaped hydraulic gate, electronic scale, rubber conveyer, by steel ball being fallen to the main belt in ore deposit, realizes auto-continuous addition;
(3) by every mill feed end top hydraulic gate, automatically control steel ball and add corresponding grinding machine;
(4) effectively reduce labor strength, eliminated tradition and added the potential safety hazard that ball mode exists.
Below in conjunction with drawings and Examples, the utility model is described further.
