Abstract

The utility model relates to a mineral dressing device for graphite, which is a fine-grinding regrinding machine for the graphite. The utility model uses a motor to drive a belt and a main shaft; a cylinder body is provided with a medium inside; the main shaft is a hollow shaft; the top part of the main shaft is provided with a feed inlet; the lower part of the cylinder body is successively provided with a first-segment impeller and at least three double-suction closed impellers inside from bottom to top; the closed impellers are embedded in the first-segment impeller. The machine has convenient and reliable operation and self-suction function; the utility model adopts the closed impeller, and thus the utility model has lifting function, and can increase the linear speed of the medium, causing the strip flowing area of the original machine to be changed into a laminar flowing area, and increasing the self circulating quantity of impellers; grinding concentration is as high as 40 percents, increasing production efficiency.

Description

Graphite correct grinding regrind mill

The utility model relates to a kind of graphite mechanical beneficiation equipment, definite a kind of graphite correct grinding regrind mill of saying so.

At present, graphite correct grinding regrind mill is to utilize differential ore dressing principle, and impeller belongs to unshrouded impeller, graphite correct grinding regrind mill as the patent No. " 91226764 ", though alternative 3-4 traditional table grinders, ore milling concentration still is 20%, can not further enhance productivity again.

Goal of the invention of the present utility model is to provide a kind of ore milling concentration up to 40%, production efficiency height, effective graphite correct grinding regrind mill.

The technical scheme of utility model is achieved in that graphite correct grinding regrind mill structure mainly comprises motor, belt, belt pulley, upper shell and lower shell are equipped with medium in the cylindrical shell, upper and lower cylindrical shell is connected as a single entity by ring flange, one side of upper shell has discharging opening, and opposite side is equipped with motor; Its structure also comprises main shaft, bearing body, first section impeller, double shrouded wheel, double suction double shrouded wheel; On the upper shell upper spindle bearing body is housed, a first section impeller and at least three double suction double shrouded wheels are housed in the lower shell of main shaft bottom from bottom to top successively; Double shrouded wheel is inlayed and is contained in the first section impeller, and double shrouded wheel and first section impeller are with main shaft and are threaded; Main shaft is a quill shaft, and its top has charging aperture, and screw thread is arranged at the bottom; First section impeller is discoid, and there is ladder hole at the center, and the less hole of internal diameter is a screwed hole, inlays in the bigger hole of internal diameter double shrouded wheel is housed, and the disk two sides of first section impeller and the middle part of dish are distributed with the identical blade of shape and position.

The utility model machine gravity height is low, and is easy to use and reliable; Adopt hollow spindle guide ore deposit, regrind mill has self-suction function; Adopt double shrouded wheel, have enhanced feature, and can improve the linear velocity of medium, also make the bar stream district of original machine become the laminar region, increased the self-loopa amount of impeller; Ore milling concentration has improved production efficiency greatly up to 40%, and is effective.

Fig. 1 is the structure diagram of graphite correct grinding regrind mill;

1 lower shell, 2 upper shells, 3 main shafts, 4 bearing bodies, 5 belts, 6 belt pulleys, 7 motors, 8 charging apertures, 9 double shrouded wheels, 10 first sections impellers, 11 double suction double shrouded wheels, 12 media;

The structural front view of first section impeller 10 of Fig. 2; 14 is blade;

The structure vertical view of first section impeller 10 of Fig. 3; 13 is ladder hole.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Shown in Fig. 1-3, in the cylindrical shell of graphite correct grinding regrind mill medium 12 is housed, upper and lower cylindrical shell 2,1 is connected as a single entity by ring flange, and a side of upper shell 2 has discharging opening 15, and opposite side is equipped with motor 7; On upper shell 2 upper spindle 3 bearing body 4 is housed, a first section impeller 10 and at least three double suction double shrouded wheels 11 are housed in the main shaft 3 bottom lower shells 1 from bottom to top successively; Double shrouded wheel 9 is inlayed and is contained in the first section impeller 10, and double shrouded wheel 9 and first section impeller 10 are with main shaft 3 and are threaded; Main shaft 3 is a quill shaft, and its top has charging aperture 8, and screw thread is arranged at the bottom; First section impeller 10 is discoid, and there is ladder hole 13 at the center, and the less hole of internal diameter is a screwed hole, inlays in the bigger hole of internal diameter double shrouded wheel 9 is housed, and the disk two sides of first section impeller 10 and the middle part of dish are distributed with the identical blade 14 of shape and position.Double shrouded wheel 9 and double suction double shrouded wheel 11 all adopt the structure of double shrouded wheel in the present water pump.

When the charging aperture 8 of 40% concentration ore pulp by main shaft 3 upper ends adds, ore pulp flow to along the main shaft of hollow and is contained in main shaft 3 bottoms, by double shrouded wheel 9 graphite is got to first section impeller 10, first section impeller 10 together dished out graphite with medium 12, medium 12 produces speed difference with graphite, and the blade exit place forms zone of positive pressure, and forms negative pressuren zone between two impellers, make machine have self-suction function, reach better grinding efficiency.
