Description
Technical field
The present invention relates to a kind of integration apparatus system, especially relate to a kind of integration apparatus system for mineral material grinding classification ore dressing, belong to metallurgical production equipment de-sign manufacturing technology field.
Background technology
In Proccessing technology, a classification often important operation prepares, and the quality of classification directly has influence on the height of the technical-economic indexes such as the concentrate grade of the production capacity of grinding machine, product quality and follow-up sorting operation and the rate of recovery.In ore dressing classification field, about classifying equipoment is all generally carry out graded operation by the active forces such as gravity, centrifugal force and mechanical oscillation and principle, ore dressing is divided into usually gravity hydraulic classification equipment, centrifugal force hydraulic classification equipment and high frequency fine screen three major types.Wherein the main representative of gravity hydraulic classification equipment is spiral classifier, and the main representative of centrifugal force hydraulic classification equipment is hydrocyclone.
Spiral classifier is a kind of the most frequently used flat flow hydraulic classification equipment during ore dressing classification is produced.Vary in size by means of solid grain, proportion is different, the principle that thus sinking speed is in a liquid different carries out mechanical classification.Thin ore particle swims and becomes to overflow in water, and rough grain is sunken to bottom land, utilizes flight to screw in mill feeding mouth and returns and regrind.
For adapting to different partition size requirements and the difference of operation property, spiral classifier is divided into immersion, high-weir type and low weir formula three kinds by size.Be usually used in ore grinding closed cycle to carry out by the operation of 0.3-0.15mm grade-classification ore pulp.Due to equipment, to there is classification area little; The qualified grain size ore particle separated is long on horizontal cross flow path, easily causes secondary settlement; And helical blade rotates and causes the impacts such as ore pulp disturbance, the defect such as cause poor product quality and classification efficiency is low.Classification efficiency, generally at about 30%-50%, the highlyest also only reaches 60%, and sand setting concentration can reach more than 80%.
The mainly centrifugal sedimentation of hydrocyclone operation principle, when two-phase to be separated or three-phase mixed liquor enter after in cyclone from cyclone material inlet with certain pressure, produces the strong rotational shear turbulent motion of strong Three-Dimensional Elliptic.Because the density of particle is different, its centrifugal force be subject to, centripetal buoyancy, fluid drag etc. vary in size, and by centrifugal sedimentation effect, most crude particle and heavy phase are discharged through cyclone underflow opening, and namely most of fine grained is gently discharged by overflow pipe, thus reach the object being separated classification.The mode of operation of hydrocyclone comprises: classification, concentrated, dehydration, desliming, desanding, washing, super-fine classified etc.
High frequency fine screen drives screen frame to do rectilinear motion by the electrical vibrator that two direction of motion is contrary, and two electrical vibrators are applied to making a concerted effort by the center of gravity of screen frame on screen frame, and therefore on screen frame, the exciting force of each point is in the same size.Ore pulp feeds from mine distributor top or bottom, is evenly divided into multichannel through mine distributor, then through entering multiple ore feeder respectively to ore deposit flexible pipe.Ore feeder is sprinkled upon compass screen surface upper end equably ore pulp.Material on compass screen surface is owing to being subject to the vibration of the little amplitude of high-frequency continuously, the compass screen surface tilted is done continuous print jump, make material dispersion, fine becomes undersize through sieve aperture in the process of mixing well, and the material being greater than sieve aperture makes continuous print skip-forwards on the compass screen surface tilted, finally jumping out screen cloth becomes oversize.
No matter be which kind of equipment above-mentioned and ore mill are supporting, all be unable to do without the existence of water.And take horizontal roller mill as " the dry milling grading technology " of grinding attachment, if use above equipment supporting with it, the moisture content of material returning horizontal roller mill must be caused large, and ore viscosity in grinding machine is large, affect grinding machine normally to produce, effectively cannot organize production.
Summary of the invention
