Abstract
INTRODUCTION Hebel brick or lightweight brick is a type of building material replacement for red brick, has a light weight compared to other bricks. Because of its various advantages, hebel bricks are increasingly sought after and in demand, especially by housing developers. Hebel brick is used as the main foundation in making the walls of the house. This is because hebel bricks are economical, lightweight, efficient and fast enough to be used in the construction of housing projects, apartments, hotels and other property projects. One of the materials used in making hebel bricks is sand. The water content of the sand used will affect the quality of the hebel bricks made. The less water content in the sand, the better the quality of hebel bricks will be made. To get sand with a little water content, it is necessary to do the drying process. And this fast drying process is carried out using a rotary dryer machine with a heat source for drying it from biomass energy. Therefore, this rotary dryer machine is designed to meet the need for dry sand with little water content. This rotary dryer machine is made by calculating the capacity of the dried material, rotary dryer rotation, the distance of moving material in the rotary dryer, the travel time of materials starting from entering to exiting, the motor power needed to rotate the rotary dryer wall and how much heat is needed to dry the sand. And from these calculations can be analyzed the performance of this rotary dryer machine, to determine the suitability between design calculations and test results. RESULTS AND DISCUSSION This rotary dryer machine is made to dry sand as raw material in making hebel bricks. This machine is designed for a capacity of 2 tons/hour. This rotary dryer machine has a length of 4,631 mm, width of 2,238 mm and height of 2,655 mm. The components in this rotary dryer machine, including: rotary dryer shell, inlet hopper, outlet hopper, base frame, gear motor, sprocket, and biomass furnace. The design of this rotary dryer machine is shown in Figure 1 below: Figure 1. Rotary Dryer Design. Keywords: Hebel brick, Dry sand, Drying, Rotary Dryer, Biomass Energy, Heat. References 1.
