Cement, additives, and water are all going through a weighing system before ending up in the mixer. The Haarup skip hoist and mixer stand for quality, combined with an excellent water measuring system and controls from Sauter, a batching plant, was built of outstanding quality, especially for the region.The block and paver machine RH 600-3 VA produces with a production board dimension of 1.400 x 700 mm. The capacity of this block and paver machine is matches the size of the island. A big board machine would exceed the current demand requirements. This block and paver machine will manufacture segmental concrete pavers and slabs, concrete hollow and full blocks, kerb stones, with a height of 25 mm up to 300 mm. The RH 600-3 VA also has the ability to make various other concrete products, but they are currently not needed on Bonaire, such as grass blocks or segmental retaining walls.To maintain simplicity, a forklift rack system is utilized to store the production boards for product curing. This system offers the advantage of scalability as the plant grows.The plant can start with a minimal number of racks and production boards. When sales are growing, so can the number of product boards and racks. Ideal for emerging countries or small islands. CBKF started with 1.000 production boards but in the first year they upscaled that number twice because of the high demand for the products. It was also determined that product packaging should be performed in a cost-effective manner, thus a manual cuber was installed on the dry line. Lifting the products with an electrical hoist with a pneumatic 4-sided clamp from two production boards and manually guided to the cube. When the cube is ready, manual strapping is applied and the cube is brought to the yard.A production board buffer is accommodating the cross conveyor of the empty production board return next to the RH 600-3 VA to prevent waiting times due to a lack of production boards. The block and paver machine receives an empty production board either directly from the cross conveyor delivering a production board to the board magazin or from the buffer when the cubing process is not ready. Also in reverse, when the cuber is ready to cycle and the block and paver machine is not ready, the buffer can take a production board out.To build up a new market, CBKF installed the RH 600-3 VA. The block and paver plant started in August 2022 its production. Bonaire lacked a modern concrete block and paver plant, and importing high-quality concrete products was both costly and challenging. CBKF identified a market opportunity and had consistent demand from the beginning. Within the first year, it became evident that the CBKF achieved remarkable success, to the extent that the cubing area could not Manually operated, pneumatically working 4-side clamp ATZ-P4Hess Cuber Servo 600
