In the building construction industry, the usage of materials is inevitable. Cement, bricks, timber, newer innovative composites, green accredited, and other acclaimed materials are used to build and construct buildings, megastructures, and others. Almost in every country worldwide, there is a steady increase in demand for building materials, as the construction industry is growing at a rapid rate and Contractors said they were struggling with a building material shortage. Building materials can welcome health issues subsequently for occupants or to workmen involved in building services, maintenances, demolition, and refurbishment. Subsequently, there is a need to choose non-toxic building materials. Builders, contractors, dealers, or distributors, your customers are changing, and building materials companies are not keeping up with the pace of these changes. Therefore manufacturers need to cope with that change to meet customers’ needs. On the other hand, selecting the right construction materials might be a big challenge to some users. Created in 1986, Ruliba Clays Ltd, with its head office located in Kigali, 15 km from the town center on the road Kigali-Huye, near the River Nyabarongo. Currently, Ruliba Clays occupies the first rank in providing quality clay construction materials. Among the products they offer are Roofing tiles, Walling and partitioning blocks, bricks, Maxpans ( suspension floor units), Paving blocks, Ventilators, decorative grilles, and floor tiles. Currently, the company boasts of qualified and experienced personnel and machinery fitted to have the highest production capacity to meet the ever-growing demands of the fast-expanding construction industry in the region. The factory products satisfy the quality materials S-mark, certified and produced through a system that is ISO 9001 certified to ensure durability and strength for the house. Without further delays let us take through step by step the production process of Ruliba Bricks Raw materials, mainly clay and Kaolin, are extracted from quarries or borrow pits and transported to the main factory depot by trucks or Lories. From the raw materials depot, wheel loaders are used to feed feeder boxes. Two different box feeders are available one for clay and kaolin respectively. The two ingredients are mixed at this stage and conveyed to the crusher. The mixing ratio is predetermined by the operator depending on the intended use/desired product. Being made of big blocks, the mixture is crushed into smaller size particles then supplied to the next feeder, and then conveyed to the second mixer. The supplied mixture is remixed. Equipped with pressure and humidity sensors, this automated machine, will add the necessary quantity of water, thoroughly mix the mixture to the desired standard. A visual inspection is very critical at this stage as there should be non-desired materials allowed to enter the mixer. At the end of this stage, the prepared mixture is 50% ready. Small particles, evenly mixed, with controlled water content, are released and conveyed to the next machine for its final preparation where desired plasticity, pressure, and water content are achieved. The ready mixture is then forwarded to the extruder machine where the desired plasticity is achieved by removing excess water. The processed clay is then extruded into a continuous strip to be cut with wires to form the clay into its final shape. Depending on the desired product, an appropriate form is attached to the extruder machine. After the forming and cutting, the product must be dried. Natural and artificial drying mechanisms are both available within the factory. Natural drying, referred to as open-air drying normally takes seven days while artificial drying is also known as kiln drying can perform the same task in 24hrs. The heat is extracted from the firing kiln and transported through big pipes to the drying area where drying wagons are disposed of. Dried bricks, blocks, or tiles are then forwarded to the kiln for firing. Dried products are set to the kiln wagons and will automatically enter the kiln with perfect timing. The system is here synchronized as for every wagon entering the kiln there is another one leaving with fully burnt bricks. Every 40 min, automated doors are opened to let the wagon enter/exit the kiln. The kiln has three zones, namely: the preheating zone, firing zone, and cooling zone and it takes only 24 hours for every wagon to pass through. The final stage consists of product sorting. Products are sorted and classified under different categories for commercial purposes.
