Abstract

1291691 Controlling mixing by viscosity MATERIALS & METHODS Ltd 22 Dec 1970 [7 Jan 1970] 732/70 Heading B1C [Also in Divisions C3 and G1] The mouldability of a foundry moulding composition made by mixing a sand, a binding agent such as clay, a liquid vehicle such as water and any other desired additive is determined during mixing of the constituents by measuring the load on the drive means of the mixer and comparing it with a predetermined standard load produced with a composition of the desired mouldability. The drive means for the mixer may be electrical and the load determined by measuring the drive current with an ammeter. The composition may include return moulding sand as a constituent and the temperature of the returned sand may be measured and the predetermined standard adjusted according to the temperature to allow for moisture loss during transportation of the mix.
