Overview of Precast Concrete Wall Panel Machine
We are the first to develop, design, and manufacture the extrusion type of precast wall panel machine in China. This precast wall panel machine operates on the principle of extrusion, setting it apart from traditional pulling mold machines, pushing machines, and vertical wall panel molds. A significant advantage of this machine is the quality of the finished wall panel. The concrete wall panels produced are smooth and wrinkle-free, with a dense and compact interior that provides high strength.
Work Principle
The structure of the extrusion precast concrete wall panel machine is straightforward, primarily divided into three parts: the power system, extrusion system, and vibration system. The main motor, ranging from 5.5 to 11 KW, serves as the power unit for the machine. It transmits power to the extrusion system via the gearbox. The extrusion unit consists of three to twenty augers, with the number determined by the wall panel size and the number of holes required. These high-speed rotating augers effectively extrude and compact the concrete material, transporting it into the molding cavity of the machine. The molding cavity's upper section features a vibration device, where a high-frequency vibration motor vibrates and compacts the concrete through repeated tamping of the vibration plate. The wall panels are formed as they are extruded and vibrated, following the movement of the machine.
Materials
The raw materials suitable for this precast wall panel machine can include both ordinary concrete and lightweight concrete, without the need for foamed concrete materials. This flexibility means that raw materials are not limited by region or country. Specifically, ordinary concrete is made from cement, sand, fly ash, and crushed stone. In contrast, lightweight concrete incorporates a variety of aggregates. Commonly used lightweight aggregates consist of industrial slag, waste concrete building materials, ceramsite, volcanic rock, shale, expanded perlite, pumice, and more. It's important to note that wall panels made from ordinary aggregates are 30-40% heavier than those created with lightweight aggregates. Therefore, the choice of aggregates is influenced by the specific situation of the customer and the desired.
