With the growing demand for construction materials in Nigeria, Asphalt Unity Construction turned to Sandvik Construction in order to help them achieve increased production capacity. The company, based in Nigeria, began operations in 2009, and is now one of the leading construction companies in the eastern region of Nigeria. The company’s main material application is crushing basalt and granite to be sold on to building contractors. The basalt is commonly crushed for use as an aggregate in construction projects such as road base, concrete aggregate, asphalt pavement aggregate and railroad ballast. With a focus on delivering high quality, in recent years the company has looked to become more competitive. Having already experienced what Sandvik stationary crushers can produce, they decided to consider the Sandvik Construction Mobile Crushers and Screens portfolio to help them achieve their annual production target thereby meeting the industry demands in the Nigerian Delta State.
To meet their high capacity requirements of up to 700 t/h, Asphalt Unity Construction chose the UJ640 jaw, together with the US440i and UH640 cone crushers to work alongside two QA451 Doublescreens (Fig.). The required product sizes are 0-25 mm and 0-35 mm, so the combination of jaw and cone crusher means the abrasive material can be broken down easily to these levels, with the jaw breaking down the material and the cone providing the shaping. Following the success of the mobile screens and crushers on its basalt application, Asphalt Unity Construction is looking to expand its fleet of equipment to help the company reach a new goal of 1500 t/h. With high production capacity machines available, the Sandvik Construction Mobiles product range will put them in the ideal position to achieve this aim.
