Opis:: This article shows the results assessment of the impact of various reclamation methods with the use of mineral wool and municipal sewage sludge on chemical and biological indicators, which have an impact on the improvement of the quality of soil degraded by sulfur well mining. The results of the research showed that the type of waste together with it application method, had a beneficial effect on the shaping of the chemical and biological properties of soil. The most favorable effect was noted in the conditions of combining mineral wool with sewage sludge. At this work we used the PHYTOTOXIKIT biological test, as an indicator of the ecotoxicological effect of selected waste added, for the efficiency of the soil remediation process.

Opis:: The paper deals with the problem of water separation from a mixture of wet loose material using a worm, or auger, dewaterer, whose working element is a full auger with variable thread pitch, rotating in a fixed trough. The extrusion of water from the wet material suspension, consisting of a mixture of mineral wool tufts and granules, is effected in the auger dewaterer by entraining and compressing the wet bulk material through the threads, the varied pitch of the conical screw, and the rotation of the auger.The thread faces and thread edges of an improperly designed screw of the auger dewaterer by Advanced Metal Powders s.r.o. showed notable wear from the applied pressure of the packed wet bulk material (passing through the threads of the different pitch of the conical auger). Finding the cause of the severe abrasion and preventing excessive further wear of the auger was the subject of theoretical calculations and experimental verification tests, whose main conclusions are presented in this paper. The paper gives the relations that allow calculation of the volume of bulk material in individual sections of the auger dewaterer. The calculated values from these relationships, were verified and compared with the values read from the 3D CAD system for designing SolidWorks Premium 2012 SP 5.0 models.The percentage compression values of the loose material in the threads of differential pitch of the conical auger of the unsuitably designed auger-screw dewaterer by Advanced Metal Powders s.r.o. allowed us to define recommendations that, applied, would ensure malfunction-free operation of the auger-screw dewaterer.
