Instalación y pruebas de funcionamiento del parque circular de prehomogeneización de caliza en la empresa Unión Cementera Nacional UCEM S.A. -planta Chimborazo.

Abstract

The objective of the present graduation work is the installation of the circular limestone pre-homogenization park within the new clinkerization line in the company Unión Cementera Nacional UCEM S.A., in the Chimborazo plant. For the elaboration of the technical project it was studied the functioning and the elements that constitute the system of pre-homogenization of the limestone, same that occupies from 80% to 85% within the necessary components for the elaboration of the Clinker, this is considered as the fundamental element in the manufacture of Portland cement. During the installation, the assembly sequence supplied by the manufacturer was applied, in this case Polysius, a German company that supplies equipment for the cement industry. It was used mainly welding processes GMAW and FCAW in the joining of the elements in a definitive way, while, in removable joints, the bolted joints system was functional applying the tightening torque established in the manual, according to the diameter and quality of the joints of each bolt. In the transfer of the components to the field and its final location, tow trucks of one hundred tons of capacity are used, permitting the element to be transported, one to three were used according to the case. When verifying the correct installation, performance tests are performed to detect possible anomalies in the operation of each component of the equipment, respecting the safety standards established for this process. An equipment with a storage capacity of 31,000 tons, a stacking capacity of 1200 tons / hour and 400 tons / hour of non-shelled stacking was obtained, which is higher than the one currently used. It is advisable to follow the guidelines for use, supplied by the manufacturer and a thorough maintenance plan to ensure that the equipment within the clinkering line increases its useful life.
