Abstract
Aiming at the function and use requirements of contoured refractory aggregates with various particle sizes in the production process of unshaped refractory products and shaped refractory products, the invention provides a method for contouring a refractory aggregate. The method comprises the steps of: adding a crushed refractory aggregate (with particle size being not less than 0.5mm) and a refractory porcelain ball into an inclined ball forming mill, a V-shaped mixing machine or a ball mill according to a certain proportion, performing light and medium contouring on the refractory aggregate through co-grinding, and singly adding the crushed refractory aggregate in an edge runner (dry mill) for being ground to obtain the heavily-contoured refractory aggregate. The refractory aggregate is subjected to iron removal and ultra-strong negative pressure duct collection in the contouring and conveying processes, and the content of impurities in the refractory aggregate is further reduced, and thus various indexes of the contoured refractory aggregate can be stable.
Description
Technical field
The present invention relates to a kind of refractory aggregate (〉=0.5mm) contouring production method, the particularly fire-resistant contouring aggregate processing of the various degree of preparation mode.
Background technology
Present domestic indefinite form refractory product and typing refractory product, refractory aggregate prepares situation normally in process of production: utilize jaw crusher slightly to break, carry out fine crushing with double-roll crusher, gyratory crusher or standing crusher, through namely obtaining the various granularity refractory aggregates of downstream production usefulness after the screening.The refractory aggregate that this preparation technology produces, profile is irregular, the granularity aggregate of needle-like, the sheet of having mixed relatively largely, will reduce the product flowability in the indefinite form refractory product work progress for the downstream, thereby reduction bulk density, particularly gravity flow pouring material is more obvious to the influence of product physicochemical property; For the typing refractory product, with the percent defective that increases in moulding and the sintering process, and influence the physicochemical property of final products.
Summary of the invention
Complexity at present refractory products production process refractory aggregate granularity in preparation process, the purpose of this invention is to provide a kind of suitable refractory aggregate (〉=0.5mm) contouring preparation method, solved irregular refractory aggregate for the influence of properties of product and construction, thereby can shorten pug and mix the time improve production efficiency and product quality.
In order to achieve the above object, the present invention adopts following technical scheme to realize:
At function and the instructions for use of various fire-resistant granularity aggregates in indefinite form refractory product and typing refractory product production process, the present invention adopt with various granularity refractory aggregates (〉=0.5mm) and the refractory porcelain ball join by a certain percentage in the equipment such as nodulizer, V-Mixer or ball mill, by grinding altogether together, realize the slight and moderate contouring of refractory aggregate; With various granularity refractory aggregates (〉=0.5mm) join separately in the edge runner (chaser mill) and grind, realize refractory aggregate severe contouring.In contouring and course of conveying, refractory aggregate is carried out deironing and superpower negative pressure dust suction processing, further reduce impurity in the aggregate, guarantee that contouring refractory aggregate index is stable.
Compared with prior art, the invention has the beneficial effects as follows: by the produced various granularity aggregates of refractory aggregate shape trimming technology (〉=0.5mm), can improve the performance indications of downstream refractory product, can effectively improve workability to the indefinite form refractory product, can improve yield rate in moulding and the sintering process to the typing refractory product, thereby improve efficiency.Refractory aggregate behind the use contouring can shorten the time of mixing effectively, improves equipment operation rate; Improved the even distribution of refractory aggregate in pug mixes process simultaneously.
Description of drawings
Accompanying drawing is the technological process of production of the present invention and layout of equipment.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
As shown in the figure, refractory aggregate (〉=0.5mm) send in the bunker by artificial or conveying equipment.Material in the bunker according to the requirement of contouring degree, is adjusted the addition of every kind of material through bunker bottom feeding device by electric control system.A certain proportion of refractory porcelain ball is sent in nodulizer, V-Mixer or the ball mill by chute, carry out common mill, behind the certain hour contouring, refractory aggregate flows out along with materials flow exports through grinding machine, outlet is furnished with screening and superpower negative pressure dust exhaust apparatus, with refractory aggregate and porcelain ball separately, refractory aggregate also will measure and pack to the transition feed bin during by conveying equipment through superpower negative pressure dust suction and deironing apparatus, both qualified slightly and moderate contouring refractory aggregate.Equally refractory aggregate is transported in the bunker, adds edge runner (chaser mill) through feeding device again and grind separately, be equipped with superpower negative pressure dust suction and deironing again, both obtained qualified severe contouring refractory aggregate.
The present invention can also be used for the technological transformation project of old refractory aggregate production line except being used for grassroot project.
Above-mentioned accompanying drawing is described only to be the preferable case study on implementation of this patent; be not that this patent is done any type of restriction; every any modification, equivalent variations and modification of above case study on implementation being done according to the technical spirit of this patent is all within the category of the art of this patent protection scheme.
Claims (3)
1. will normally break the various granularity refractory aggregates that pulverize to produce (〉=0.5mm) and the refractory porcelain ball be lined with nonferrous high-abrasive material and tilting nodulizer (V-Mixer, ball mill etc.) in joining by a certain percentage, and separately with various granularity refractory aggregates (〉=0.5mm) join the shaping of carrying out certain hour in the edge runner (chaser mill) to grind altogether, the refractory aggregate that produces passes through deironing and superpower depression dust-removing again, obtain slight (moderate) contouring refractory aggregate, the latter obtains severe contouring refractory aggregate.It is characterized in that, by above-mentioned substance is ground together altogether, make refractory aggregate and refractory porcelain ball fully mix, or grind separately by equipment, the various degree contouring refractory aggregates that obtain meeting the requirements.
2. the refractory aggregate behind the contouring is transported to packaging system by conveying equipment and carries out quantitative package, it is characterized in that, refractory aggregate carries out deironing in contouring and course of conveying and superpower negative pressure dust suction is handled, and has further reduced the impurity content in the aggregate, guarantees that product index is stable.
3. determine granularity before porcelain ball additional proportion and refractory aggregate add shaping device according to the contouring degree.
