Title: Drying wet sand for ready mixed dry mortar - by mixing with fat lime and holding motionless during reaction
Inventor: WENCKER HANS
IPC: C04B2/06
Filed: 1979-11-16
Abstract: Sufficient white fat lime (quicklime) for complete conversion of the water, is added to the wet sand mixed with it and held motionless until reaction is complete. Movement of the mixt. is avoided since this causes release of heat, reducing the drying effect. The mixing is effected in a holding tank of such structure that particle movement is avoided. On mixing the material is densified by the weight of the column of material in the holding tank into which the material is poured in the direction of gravity. The method requires no fuel to provide energy for drying. The heat of reaction released drives off much of the water present in the sand, the remainder being removed by reaction.
