1. Apparatur til adskillelse af faste stoffer fra borevæske, som indeholder faste stoffer, og størrelsessortering af de faste stoffer, hvilket apparatur omfatter en kurv (312), en vibrationsmekanisme (314), et første sigtedæk (318b) og et andet sigtedæk (318c) monteret under det første sigtedæk, hvor det første sigtedæk (318b) er anbragt i en opadrettet vinkel fra en tilførselsende til en udløbsende for kurven (312), idet det første sigtedæk omfatter en overløbskant (313), således at efter at en dam er dannet på det første sigtedæk (318b) og har nået en forudbestemt dybde, afgives borevæske, som indeholder faste stoffer, over den nævnte overløbskant (313) til det andet sigtedæk (318c) for tilvejebringelse af en parallel driftsmodus, kendetegnet ved, at en ledeindretning til at vælge en parallel driftsmodus eller en seriel driftsmodus er tilvejebragt, i hvilken strømning af borevæske, som indeholder faste stoffer, ledes på det første sigtedæk og derefter ledes borevæske, som er sigtet deraf, på det andet sigtedæk, hvor en strømningsbakke (317b) er anbragt imellem det første sigtedæk (318b) og det andet sigtedæk (318c), hvor ledeindretningen, for valg af parallel eller seriel driftsmodus, omfatter en bevægelig omdirigeringsbakke (320) og den nævnte strømningsbakke (317b).
2. Apparatur ifølge krav 1, hvor den bevægelige omdirigeringsbakke (320) er forskydeligt anbragt i skinner (321).
3. Apparatur ifølge krav 2, hvor skinnerne omfatter et ekspanderbart element (320p, 320s) for selektivt at fiksere den bevægelige omdirigeringsbakke (320) i skinnerne (321).
4. Apparatur ifølge ethvert af kravene 1 til 3, som yderligere omfatter en kanal (311) til at dirigere strømning af borevæske, som indeholder faste stoffer, fra overløbskanten (313) til det andet sigtedæk (318c).
5. Apparatur ifølge ethvert af kravene 1 til 4, hvor overløbskanten er forsynet med en fremspring (487a) til at forhindre faste stoffer i at passere derover.
6. Apparatur ifølge ethvert af de foregående krav, som yderligere omfatter et grovsigtedæk (318a).
7. Apparatur ifølge krav 6, som yderligere omfatter en strømningsbakke (317a) til at lede grovsigtet borevæske, som indeholder faste stoffer, til en tilførselsende for det første sigtedæk (318b).
8. Apparatur ifølge ethvert af de foregående krav, hvor omdirigeringsbakken (320) har en kanal (324) under denne til at lede sigtet borevæske, som indeholder faste stoffer, til det andet sigtedæk, således at når omdirigeringsbakken er tilbagetrukket, strømmer sigtet borevæske, som indeholder faste stoffer, igennem kanalen (324) ned på det andet sigtedæk (318c).
9. Apparatur ifølge ethvert af kravene 1 til 7, hvor omdirigeringsbakken (320) har en kanal (316a) under denne til at lede sigtet borevæske, som indeholder faste stoffer, til en sump (316), således at når omdirigeringsbakken (320) ikke er tilbagetrukket, strømmer sigtet borevæske, som indeholder faste stoffer, igennem kanalen (316a) til sumpen (316).

13. Apparatur ifølge ethvert af de foregående krav, hvor omdirigeringsbakken (320) omfatter et håndtag (320b).
14. Fremgangsmåde til at adskille faste stoffer fra borevæske, som indeholder faste stoffer, og selektiv størrelsessortering af de faste stoffer, hvor apparaturet omfatter en kurv (312), en vibrationsmekanisme (314), et første sigtedæk (318b) og et andet sigtedæk (318c) monteret under det første sigtedæk, hvor det første sigtedæk (318b) er anbragt i en opadrettet vinkel fra en indfødningsende til en udløbsende for kurven (312), det det første sigtedæk omfatter en overløbskant (313), således at efter dannelse af en dam på det første sigtedæk (318b) og opnåelse af en forudbestemt dybde, afgives borevæske, som indeholder faste stoffer, over den nævnte overløbskant (313) til det andet sigtedæk (318c) for tilvejebringelse af en parallel driftsmodus, kendetegnet ved, at en ledeindretning til at vælge en parallel eller en seriel driftsmodus, i hvilken strømning af borevæske, som indeholder faste stoffer, ledes til det første sigtedæk og derefter ledes borevæske, som er sigtet deraf, til det andet sigtedæk, hvor en strømningsbakke (317b) er anbragt imellem det første sigtedæk (318b) og det andet sigtedæk (318c), hvor ledeindretningen omfatter en bevægelig omdirigeringsbakke (320) og den nævnte strømningsbakke (317b), idet fremgangsmåden yderligere omfatter trinnet med at bevæge den bevægelige omdirigeringsbakke for at vælge parallel eller seriel driftsmodus.
