20 Apparatet omfatter en silo 1 med en tragtformet sektion 2, der er forsynet med et understel 3. Siloen er med en skillevæg 4 delt i to kamre henholdsvis 5 og 6. Kammeret 5 har et pâfyld-ningshul 7 for tiIslagsmateriale, medens kammeret 6 har et pâ-fyldningshul 8 for bindemiddel. Ved bunden af den tragtformede 25 de! 2 findes en transportsneg 1 9 sammen med et blandekammer 10, hvilken transportsneg! 9 drives med et konstant omlobstal af en elektromotor 11. Ved bunden af kammeret 6 findes en an-den transportsneg! 12, som stâr i forbindelse med blandekam-meret gennem et faldror 13. Transportsneglen 12 drives af en 30 elektromotor 14 med en trinlos variabel hastighedsregulator. Blandekammeret 10 er forsynet med en studs 15, som indeholder en doseringsventi1 for det tilforte vand.The apparatus comprises a silo 1 having a funnel-shaped section 2 provided with a base frame 3. The silo is divided into two chambers 5 and 6 by a partition 4, respectively. The chamber 5 has a filling hole 7 for additional material, while the chamber 6 has a binder loading hole 8. At the bottom of the funnel-shaped 25 they! 2 there is a transport auger 1 9 together with a mixing chamber 10, which transport auger! 9 is driven by a constant orbital number of an electric motor 11. At the bottom of chamber 6 there is another transport screw! 12, which communicates with the mixing chamber through a trap tube 13. The conveyor screw 12 is driven by an electric motor 14 with a continuously variable speed regulator.

5 transporteur bindemidlet fremt tii blandekammeret 10 gennem roret 13. Fremforingshastigheden for den anden transportsnegl 12 kan vælges efter onske ved hjælp af den trinlost variable hastighedsregulator for elektromotoren 14. Storrelsen af den 5 indstillede hastighed, hvormed den anden transportsnegl 12 drives, bestemmes eksperimentelt pà en sâdan mâde, at der op-nâs det onskede blandingsforhold mellem ti 1 siagsmateriale og bindemiddel for den aktuelle fugemortel eller betonmortel. Hastigheden for transportsneglen 9 og for blanderen i blande-10 kammeret 10 forbliver imidlertid konstant hele tiden.The conveyor binder advances through the mixing chamber 10 through the pipe 13. The feed rate of the second conveyor screw 12 can be selected after Wednesday by means of the infinitely variable speed regulator for the electric motor 14. The magnitude of the 5 set speed at which the second conveyor screw 12 is driven is determined experimentally. in such a way that the desired mixing ratio between ten liters of saw material and binder for the actual grout or concrete mortar is obtained. However, the speed of the conveyor screw 9 and of the mixer in the mixing chamber 10 remains constant throughout.
Mortel kan tilberedes pâ ovenanforte màde ved en kontinuerlig procès. Dosering af tilslagsmaterialet og bindemidlet kan ske uden brug af ventiler. Folgelig har dé to transportsnegle 9 og 15 12 en dobbelt funktion, nemlig dosering og transport.Mortar can be prepared in the above manner by a continuous process. Dosing of the aggregate and binder can be done without the use of valves. Consequently, the two transport augers 9 and 15 12 have a dual function, namely dosage and transport.
Udlobet ved bunden af tilslagsmateriale-kammeret 5 kan lukkes ved hjælp af en skydelem 20, sâledes at blandekammeret fâr mu-lighed for at blive tomt. Efter at skydelemmen 20 er blevet 20 lukket og tilferslen af bindemiddel stoppet, tommes blandekammeret 10 og det spules rent med vand.The outlet at the bottom of the aggregate chamber 5 can be closed by means of a slider 20, so that the mixing chamber has the opportunity to become empty. After the slide 20 has been closed and the binder is stopped, the mixing chamber 10 is emptied and rinsed clean with water.
For at kunne betjene skydelemmen 20 i frostvejr er der nær ved den kant, som understotter 1emmen, monteret en elektrisk var-25 meledning. Desuden er der i den overste de! af tilslagsmateriale-kammeret tilvejebragt et varmeelement 21 for at forhindre eller eliminere enhver sammenklumpning af tilslagsmaterialet.In order to operate the slider 20 in freezing weather, an electric heating line is mounted near the edge supporting the latch. Besides, there are in the top ones! of the aggregate compartment provided a heating element 21 to prevent or eliminate any clumping of the aggregate.
&rodannelser i bindemiddel-kammeret er forebygget ved tilveje-30 bringelsen af et pumpestempel 16 med tværgâende arme 17, som bevæger sig op og ned i kammeret. Denne op- og nedadgâende be-vægelse af stemplet 16 fremkaldes ved hjælp af en knast 18.& root formation in the binder chamber is prevented by the provision of a pump piston 16 with transverse arms 17 moving up and down the chamber. This upward and downward movement of the piston 16 is induced by a cam 18.
