We know that clay bricks are gradually being replaced by non-fired bricks. Compared with the consumption of traditional clay bricks, the use of non-fired brick machines to consume non-fired bricks can omit the firing process, simplify the process, reduce pollution, and help maintain the environment. So what is the process of using the cement brick machine to consume the non-burning brick? Today I will introduce several steps in the general production process of concrete block.
Crushing: Use the crusher to crush the original materials needed for consumption. Selection: sieving the crushed raw materials to ensure that the particle size of the sieved materials is 0~2mm. Ingredients: stop the ingredients according to the mixing ratio, the purpose is to interact with the original materials through the consumption process to generate certain hydration products and structures , So that the non-fired brick can reach the requested strength and other properties. The ingredients should be adjusted in time according to the unsteady changes in the quality of the original materials.
Grinding material: The effect of using wheel grinding equipment to dispose of raw materials is irreplaceable by other equipment. After the raw materials are wheeled, the averageness and adhesion are improved, the particle grading is more reasonable, and the appearance and dryness of the green body are The improvement can increase the strength of the brick. At the same time, wheel milling also stimulates the activity of fly ash in alkaline media, greatly improving and improving the quality of bricks.
Compression molding: The material after wheel rolling, stirring and rolling is sent to the silo of the brick press, and is pressed into bricks by the host machine. The pressure of forming and the speed of pressing have a great influence on the quality of the brick. In addition, the appearance quality of pressed bricks should meet the requirements of the rules. Curing: The bricks are stacked after being formed, and cured with water after 24 hours, 2 times a day in spring and autumn, 3 times a day in summer, and can be used after 20 days.
