In the article, a device for measuring the parameters of the rotational movement of the auger for dewatering solid waste is proposed based on the analysis of signal processing methods and measurement of physical quantities. It can be used in the development of high-performance special vehicles for transporting waste as the main link in the structure of machines for the collection and primary processing of solid waste. The structural scheme of the means and block diagram of the microcontroller control program algorithm for implementation of the device for measuring the parameters of the rotational motion are proposed. The main technical characteristics of the proposed means are given. The results of experimental tests for measuring the parameters of rotational motion are shown. The results of experimental studies, which are given in the work, confirmed the reliability of the measured parameters.

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.
