Abstract
The utility model provides an ore discharge separator for a ball grinding mill. The ore discharge separator comprises a conical mesh cage, wherein two ends of the mesh cage are respectively to be a circular opening, the mesh cage is fixedly welded by lengthways round steel bars evenly distributed to be conical, the mesh cage is internally provided with a spiral steel bar, and the spiral steel bar is fixedly welded with the lengthways round steel bars; two ends of the lengthways round steel bars are respectively welded with a flat steel bar inside and outside; and the spiral steel bar is gradually thickened from one end to another end, and one thick end of the spiral steel bar is fixedly welded with a small-opening end of the conical mesh cage. The ore discharge separator is simple in structure, can be directly and fixedly welded at an ore discharge opening of the ball grinding mill, and can be used for discharging the ore in a classifying and separating way according to the size of volume, so that the large-volume steel ball or hard rock can not enter follow-up machining equipment, the follow-up machining equipment can be protected, the period for discharging the steel ball or the hard rock when the ore discharge separator stops can be further prolonged, and the work efficiency can be improved.
Description
Technical field
The utility model relates to the ball mill ore discharging separator, and it is a kind of device that hard rock or the steel ball of the large volume in ore discharge can be excluded, and belongs to mechanical field.
Background technology
Ball mill is one of widely used Super-fine grinder machinery in industrial production, is after material is broken, then disintegrating apparatus.Ball mill inside is placed with a plurality of a lot of steel balls that are placed with, during ball mill work, and the body fast rotational, steel ball inertia drops under Action of Gravity Field after rising, and impacts and treats comminuting matter.The direct ore discharge of material after ball mill is pulverized is further processed to following process equipment spiral classifier; often can mix the small ball that steel ball fragment, wearing and tearing are arranged and the hard rock that is not impacted pulverizing in ore discharge; steel ball fragment, small ball and hard rock can make grader helical rotation resistance increase, and even can cause the equipment breakdowns such as big and small blade and main shaft fracture, motor reducer damage.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model discloses the ball mill ore discharging separator, steel ball, steel ball fragment and hard rock that this device is can be with the volume in ball mill ore discharging larger are concentrated and are separated, and avoid entering in following process equipment cause damage of equipment.
The ball mill ore discharging separator comprises conical cylinder mould, and the two ends of cylinder mould are circular open, and cylinder mould is provided with the spiral steel bar for evenly being arranged into conical vertical round steel solid welding in cylinder mould, and the spiral steel bar is welded and fixed with vertical round steel.
The two ends of described vertical round steel inside and outside both sides respectively all are welded with flat steel bar.
Described spiral steel bar becomes close gradually from an end towards the other end, the osculum end solid welding of the end that the spiral steel bar is close and conical cylinder mould.
When this device uses, the big opening end of cylinder mould is fixed on the gape of ball mill, the gape of following ball mill rotates together, at first fine particle in ore discharge will drop down from the gap of cylinder mould, final larger particle can not fall down from the gap of cylinder mould, discharge from the other end outlet of cylinder mould, processed by centralized collection.This device is isolated bulky steel ball, steel ball fragment and the hard rock in ore discharge, has protected follow-up equipment, extends the service life of follow-up equipment, also avoids follow-up equipment regularly to shut down simultaneously and discharges steel ball, steel ball fragment and hard rock, increases work efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the state diagram that cylinder mould does not weld the spiral steel bar,
Reference numerals list: 1-cylinder mould, 2-flat steel bar, 3-vertically round steel, 4-spiral steel bar.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand the following specific embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model.Need to prove, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of particular elements geometric center.
See Fig. 1 and Fig. 2, this ball mill ore discharging separator comprises conical cylinder mould 1, the two ends of cylinder mould 1 are circular open, cylinder mould is provided with spiral steel bar 4 for evenly being arranged into conical vertical round steel 3 solid weldings in cylinder mould 1, spiral steel bar 4 is welded and fixed with vertical round steel 3.This device, the cylinder mould 1 vertical round steel of surrounding is lined up taper shape, the gap of big opening end is larger, and the gap of osculum end is less, during installation, big opening end is arranged on the gape of ball mill, after ore discharge entered cylinder mould, at first fine particle dropped down from the cylinder mould gap, and bulky particle is stayed in cylinder mould, follow the cylinder mould rotation and advance, finally concentrate from the other end of cylinder mould and discharge.The structure that spiral steel bar 4 is reinforced cylinder mould also has the effect of buffering to advancing of ore discharge.
The two ends of described vertical round steel 3 inside and outside both sides respectively all are welded with flat steel bar 2.Flat steel bar 2 is reinforced cylinder mould 1 structures, also facilitates cylinder mould 1 two ends to enter or discharge mineral aggregate.
Described spiral steel bar 4 becomes close gradually from an end towards the other end, the osculum end solid welding of the end that spiral steel bar 4 is close and conical cylinder mould 1.Make the osculum end gap of cylinder mould 1 less, the big opening end gap is larger, facilitates that in ore discharge, compositional classification separates.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme that is comprised of above technical characterictic any combination.
