Diseño y construcción de una secadora de arenas para la producción de morteros en la hormigonera Hormicen

Abstract

The technical Project is based on the design and construction of a dryer of sands for the production of mortars in the cement mixer HORMICEN, to ensure the design of the dryer was carried out research on the different elements of machine, such as: burners, types of industrial dryers, as well as fuel types, composition of sand, aggregates and mortars, types of mortars, among other fundamental aspects for the implementation of the project. Next is to take all the specifications given by the concrete mixer including the sizing, the load capacity, production volumen, operating time, ease of handling, maintenance, among others. This was a grain size analysis of sand through technical specifications [10] and compared to standards suitable for this purpose (ASTM C33), the importance of the rudimentary process automation to increase the volume of production [1]. The importance of the creation of an industrial dryer is already used in different materials for sand as in our case, the most important is the removal of moisture from the material in partially low percentages. The drying of the sand for the production of dry mortar lies in that sand is exposed to environmental conditions in which moisture is directly involved with the material, the moisture makes the final result by previous processes result whit a setting of a prematurely, causing so the product does not serve for the construction. Once all the aspects of design and analysis was carried out the construction of all the constituent elements of the dryer. Whit the tests to check the operation of the machine was obtained the expected results and the satisfaction of the company.
