blokmachine

A blokmachine, or block-making machine, is a piece of industrial equipment used to manufacture concrete blocks, bricks, pavers and other precast masonry elements. It combines a mold with a system to compact and eject the material, producing uniform blocks for construction and precast applications. Block machines may be manual, semi-automatic, or fully automatic and can handle different block shapes and sizes by using interchangeable moulds.

Most blokmachines use a cementitious mix of cement, aggregates (sand or gravel), water and sometimes supplementary materials such as fly ash or slag. The material is delivered to a hopper or mixer, then placed into the mould. A hydraulic or mechanical press applies high pressure to compact the mix, after which the newly formed block is released from the mould and moved to a curing area. Some systems include integrated conveyors, robotic handlers, or curing chambers as part of a production line.

Common outputs include hollow concrete blocks, solid blocks, interlocking blocks and paving stones. Mold designs and machine configurations determine block dimensions, reinforcement options, and surface textures. Curing methods vary from air curing to steam or autoclave curing, depending on the product and production setup.

blokmachines are used worldwide in construction and precast industries, offering increased production rates and better consistency compared with manual block making. They require regular maintenance, proper material handling, and adherence to safety standards to minimize hazards associated with high-pressure equipment.
