Description

A kind of slag grader
Technical field
The present invention relates to a kind of slag grader, relate to specifically a kind of slag that is specially adapted to containing metal iron, also be applicable to the grader that the industry materials such as metallic ore, nonmetallic ore, metallurgy, chemical industry select powder simultaneously.
Background technology
The main component of slag is calcium oxide, magnesia, and next contains the oxides such as iron, silicon, aluminium, also has a small amount of metallic iron.Because of reasons such as its composition and treatment process, there is following problem in the classification of ground steel slag:
1, in the slag composition, calcium oxide content is the highest, and after overheated stewing PROCESS FOR TREATMENT with water reaction, have part calcium hydroxide to produce, have stronger cohesiveness after levigate, powder is difficult for breaing up, and exists fine powder and separates difficult problem with meal.
2, its distribution of particles of ground steel slag has and is bimodal shape, contain 20% superfine powder of left and right below 10 microns, because of fineness meticulous, powder easily absorption is agglomerating, also be wrapped in simultaneously metallic iron around, adopt common powder concentrator or O-SPA powder concentrator, ground-slag separates not thorough with iron particle in slag, and classification efficiency is low.
3, low because of classification efficiency, cause following three kinds of phenomenons: (1) qualified ground-slag does not have sorting to go out, return grinding machine again grinding can cause product to cross grinding, make the grain composition of product unreasonable, can not give full play to the activity of slag micro powder, both reduce product quality, increased again grinding pow consumption; (2) metallic iron through magneticly electing because of the surface adhesion fine powder, causes iron fine powder, the grain slag impurity content selected to exceed standard, and does not reach product requirement, has reduced added value of product; (3) too much because of ground-slag, can cause the bed of material thicker, in ground-slag, meeting wrapping portion metallic iron can not be by magnetic separation out; again be returned and carry out grinding again in mill, after certain hour, the enrichment in grinding machine of the iron in slag; can stop up grate plate, mill inner ventilation be worsened, when increasing abrasion; also reduced mill efficiency; grinding pow consumption rises, and also can produce full mill phenomenon, and production can not normally be moved; must irregularly shut down cleaning to grinding machine, just can keep production.Cause abrasion increase, power consumption to rise, operation rate, the operating cost height waits vicious circle.
In a word, the classification efficiency of powder concentrator is directly to have restricted the technology bottle diameter that the iron content steel slag dry method is processed, and does not break through and selects the powder technology just can not really realize the industrialized production that steel slag dry method is processed.
Summary of the invention
The present invention has taken into full account the powder characteristics of slag, the slag that a kind of efficiency of separation is high, disposal ability is large, energy consumption is low grader is provided, have that efficient is high, good seal performance, partition size is adjustable, be easy to the advantages such as maintenance, be easy to installation, reliable, thoroughly solve the technical barrier of slag ground-slag and iron particle classification.
The present invention is achieved through the following technical solutions:
Slag grader of the present invention comprises rack-mounted body, it is characterized in that: the body internal upper part is provided with rotor, and rotatable horizontal feed pipe is installed in the middle part of body, and in body, the bottom is provided with air distribution plate and meal bucket; Rotor is upwards aimed at the body top outlet inlet, and air outlet connects the sack cleaner air inlet, and the sack cleaner air outlet connects air-introduced machine; Feed pipe is positioned at one section of body and is the grid pipe, respective rotor above the grid pipe, below corresponding air distribution plate.
Slag grader of the present invention, preferred version be, also is equipped with on frame for the motor that drives rotor, and rotor is by angular wheel and main shaft connection for transmission, and main shaft is arranged on upper machine body, and main shaft is connected with motor.Meal bucket installed inside has wearing plate, and air distribution plate is positioned at above the meal bucket.Body is provided with access door.Be provided with the oiling pipeline to the bearing oiling in the main shaft that rotor connects.The angle of meal bucket taper bus and level is 50~70 °.
The present invention has the following advantages:
1. this separator adopts horizontal feed, has increased the time of staying that material has grader inside, makes material dispersion evener, has the function of charging and cloth, has greatly increased stock grading efficient.
2. this grader lower body is provided with air distribution plate, and the material of process primary election can pass through secondary material distributing, after coarse granule is subject to further clashing into and disperses simultaneously, can carry out secondary sorting, has improved classification efficiency.
3. the set feed pipe of this grader can be connected on ball mill top discharge pipe, need not to increase power, and the air distribution plate of dividing into simultaneously is that gravity and inertia by means of material carries out classification to the dispersion of material, selects powder kinetic energy little, can be obviously energy-conservation.
4. this separator can strictly be controlled the fineness of material by regulating the rotating speed of rotor, can adjust fineness of materials according to user's request, and easy operating is convenient to adjust.
5. this separator has taken into full account the large problem of metallic iron abrasion in the slag, and the body inwall has been installed wearing plate, and is for convenience detach, increased service life of equipment.
6. this grader feed pipe can set up charging aperture, but mounted motor drives simultaneously, is used for other grinding or the disintegrating apparatus of non-ball mill, applied range.
