Abstract
Aiming at function and utilization requirements of refractory aggregate in indefinite-form refractory products and definite-form products after refractory aggregate of various size fractions achieves premixing and granularity homogenization, the invention provides a granularity homogenization method of the refractory aggregate of various size fractions. The granularity homogenization method of the refractory aggregate of various size fractions includes the following steps of adding broken refractory aggregate (15mm-14mm, 14mm-13mm, 13mm-12mm, 12mm-11mm, 11mm-10mm, 10mm-9mm, 9mm-8mm, 8mm-7mm, 7mm-6mm, 6mm-5mm, 5mm-4mm, 4mm-3mm, 3mm-2mm, 2mm-1mm, 1mm-0.5mm, 0.5mm-0mm) to a weighting type distribution bin, adding the refractory aggregate to a moving trolley through a feeding machine according to a certain proportion, enabling the refractory aggregate to enter a mixing machine through the moving trolley to be blended and premixed, and measuring and packaging the refractory aggregate through delivery equipment, wherein deironing and superstrong negative pressure dust absorption treatment are conducted on the premixed refractory aggregate in the process of delivery, and the content of iron and other impurities in the refractory aggregate is further reduced. Therefore, stability of each indicator of the premixed refractory granularity-homogenized aggregate is guaranteed.
Description
Technical field
The present invention relates to a kind of each grade refractory aggregate granularity homogenizing production method, particularly each grade refractory aggregate premix preparation of batch mode of the low impurity of low iron.
Background technology
Present domestic indefinite form refractory products and typing refractory products, refractory aggregate prepares situation normally in process of production: utilize broken, obtain producing several size ranges (15～10mm, 10～8mm, 8～5mm, 5～3mm, 3～1mm, 1～0mm) the refractory aggregate of use after screening, without pre-mixed ingredients, participate in finished product production batching, the mixing in downstream directly.The refractory aggregate that this preparation technology produces, because size range is wider, the material supplier adopts different disintegrating apparatus can draw the refractory aggregate that size fractionated distributes, such as adopting double roll crusher and cone crushing, the same raw material goes out in 8～5mm grade scope, 8～the 7mm that obtains, 7～6mm, 6～5mm size-grade distribution ratio are different, and this difference has in various degree impact for the refractory products physicochemical property in downstream.
Summary of the invention
Complicacy for size-grade distribution in present refractory products production process refractory aggregate, the purpose of this invention is to provide the production method that a kind of suitable refractory aggregate is mixed in advance, solve the impact of size fractionated refractory aggregate for product performance and construction, improved production efficiency and quality product.
In order to achieve the above object, the present invention adopts following technical scheme to realize:
For function and the service requirements of various grade refractory aggregates in indefinite form refractory products and typing refractory products production process, the present invention adopts and joins by a certain percentage various grade refractory aggregates after refinement in mixing machine, by weigh, proportioning, mixing, realize the granularity homogenizing of refractory aggregate.Granularity be mixed in advance and course of conveying in refractory aggregate carried out deironing and superpower the aspiration of negative pressure process, further reduce impurity in aggregate, guarantee that the refractory aggregate index of granularity homogenizing is stable.
The production technique that also there is no at present refractory aggregate granularity homogenizing, the invention has the beneficial effects as follows: by the produced various granularity homogenizing aggregates of refractory aggregate granularity homogenizing process, can improve the performance index of downstream refractory products, can effectively improve workability to the indefinite form refractory products, can improve yield rate in moulding and sintering process to the typing refractory products, thereby improve efficiency.Refractory aggregate after use granularity homogenizing can shorten the time of mixing effectively, improves equipment operation rate; Improved simultaneously the use properties of product.
Description of drawings
Accompanying drawing is the technological process of production of the present invention and layout of equipment.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
As shown in the figure, (15～14mm, 14～13mm, 13～12mm, 12～11mm, 11～10mm, 10～9mm, 9～8mm, 8～7mm, 7～6mm, 6～5mm, 5～4mm, 4～3mm, 3～2mm, 2～1mm, 1～0.5mm, 0.5～0mm) send in bunker by artificial or lifting handling equipment refractory aggregate.Each bunker is furnished with LOAD CELLS, and the material in bunker according to proportion requirement, is adjusted the add-on of every kind of material through bunker bottom feeding device by electric control system.A certain proportion of refractory aggregate is sent in mixing machine by locomotive, be mixed in advance, after mixing through certain hour, the refractory aggregate that is mixed in advance flows out along with material stream exports through mixing machine, enter in handling equipment, the refractory aggregate that is mixed in advance also will measure and pack to the transition feed bin through superpower the aspiration of negative pressure and deironing apparatus during by handling equipment, both the qualified low impurity refractory aggregate that is mixed in advance.
The present invention can also be used for the technological transformation project of old refractory aggregate production line except being used for new project.
Above-mentioned accompanying drawing is described is only the better 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.
