Abstract

The pulverising method includes separation e.g. of coarse . particles to be used in road building, and finer particles for further treatment e.g. for mixing mortar. Particles are classified in fractions of between 16/200 mm. Fine granules which are recovered after a cleaning process are added to the supply being fed to the crusher.

Description

Werkwijze voor het breken van bouw-en slooppuin.Method for breaking construction and demolition rubble.

Om gebroken slooppuin te kunnen toepassen als bouwmateriaal,betontoeslagstof of wegenbouwmateriaal,moet aan normen worden voldaan,hetgeen betekent dat storende verontreinigingen tenminste tot onder gestelde maximaal toelaatbare hoeveelheden dienen te worden verwijderd. Reinigingssystemen zijn bekend.Bij deze systemen wordt slooppuin na breken in contact gebracht met een middel,lucht of waterhoudende vloeistof,waardoor enerzijds hout en anderzijds fijne steenachtige fijne delen worden verwijderd uit het product of producten.To be able to use broken demolition rubble as a building material, concrete aggregate or road construction material, standards must be met, which means that disturbing contaminants must be removed at least up to the maximum permitted amounts. Cleaning systems are known, in which demolition rubble is brought into contact with a medium, air or water-containing liquid after breaking, whereby on the one hand wood and fine stony fine parts are removed from the product or products.

Bij de werkwijze volgens uitvinding wordt reiniging toegepast,alvorens het puin wordt gebroken en zonodig geklasseerd.Als scheidingsmiddelen zijn ook hier gassen en vloeistoffen toe te passen.In the method according to the invention, cleaning is applied before the debris is broken and classified if necessary. Gases and liquids can also be used here as separating agents.

Bij de gebruikelijke wijze van breken van slooppuin wordt puin toegevoerd aan een breker,welke het puin zo goed mogelijk op de productafmeting brengt,waarna wordt gereinigd.Als product wordt een materiaal geleverd in de fractiegrootte 0-45 mm.Gebruikelijk is om het puin te breken tot de maximale maat van 45 mm.In the usual way of breaking up demolition debris, debris is fed to a crusher, which brings the debris to the product size as closely as possible, after which cleaning is carried out. As a product, a material is supplied in the fraction size 0-45 mm. break up to the maximum size of 45 mm.

Bijvoorbeeld wordt aan de breker toegevoerd 200 ton puin per uur dat na breken wordt gereinigd.Bij reinigen verkrijgt men naast 180 ton product, 20 ton zeer fijn materiaal waarvoor geen directe toepassing bestaat en dat zich heel moeilijk laat verwerken.For example, the crusher is fed 200 tons of rubble per hour, which is cleaned after crushing. When cleaning, in addition to 180 tons of product, 20 tons of very fine material are obtained for which there is no direct application and which is very difficult to process.

Bij de werkwijze volgens uitvinding wordt veel grover gebroken en wordt grove fractie afgezonderd om te reinigen en om vervolgens te breken en uit te zeven in productfracties voor wegenbouw en/of voor toepassing in betonmortel.De hier vrijkomende fractie fijn materiaal wordt gestort op de voorraad, of wordt toegevoegd aan de stroom naar de breker,welke wordt gevoed vanaf de voorraad. De hoeveelheid,aan de grove stukken klevend,fijn materiaal wordt bij de werkwijze volgens uitvinding bepaald door het specifiek oppervlak van de grove delen,zodat deze hoeveelheid fijne steenachtige delen binnen bepaalde grenzen is in te stellen door het kiezen van de fractiegrofheid.Ten opzichte van de hoeveelheid fijne delen,welke bij de bekende werkwijzen vrijkomt,is de hier ontstane massa gering te noemen.Het is bijvoorbeeld mogelijk om bij een totale belasting van 200 ton, 100 ton grove fractie af te zonderen van 45 tot 120 mm met daarin ca: 1 gewichtsprocent aanklevend materiaal,zodat slechts 1 ton wordt teruggevoerd naar de voeding van de breker,of naar de voorraad.Doordat de totale gebroken puinhoeveelheid wordt verdeeld in een grove fractie en een fijnere fractie bedoeld voor wegenbouwmateriaal,kan goede kwaliteit betontoeslagstof worden vervaardigd uit de schone grove fractie.In the method according to the invention, much coarser is broken and coarse fraction is separated for cleaning and then broken and sieved into product fractions for road construction and / or for application in concrete mortar. The fraction of fine material released here is poured into the stock, or added to the current to the breaker, which is fed from the stock. The amount of fine material adhering to the coarse pieces is determined in the method according to the invention by the specific surface area of the coarse parts, so that this amount of fine stony parts can be adjusted within certain limits by choosing the coarseness of the fraction. the amount of fine particles released in the known processes is to be called the small mass that is produced here. For example, it is possible to separate 100 tons of coarse fraction from 45 to 120 mm with a total load of 200 tons, containing approximately: 1% by weight of adhering material, so that only 1 ton is returned to the crusher feed, or to the stock.Because the total crushed rubble amount is divided into a coarse fraction and a finer fraction intended for road construction material, good quality concrete aggregate can be manufactured from the clean coarse fraction.
