The raw material processing process includes two stages: one stage is the preparation of the raw material of the landscape brick; the second stage is the forming of the landscape brick body. The molding of certain landscape bricks is mainly achieved by the extrusion method, for other types of landscape brick molding is done after the extrusion method by the way.
The development stage of the landscape brick body has many important effects:
1, measure the various ingredients and mix well with the mixture.
2, the discharge of stones and other impurities (grass and roots, scrap metal blocks, etc.).
3, homogenization and wetting, so that the mixture to obtain the correct plasticity.
4. Break the raw material in order to obtain the desired particle size.
The preparation of the starting material can be carried out in dry processes such as powder, semi-wet (eg, mud) or wet (eg, mud). Wet preparation with mud is not commonly used in sintered brick and tile industry.
, In the dry preparation of raw materials, the water content of 10% level, semi-wet preparation of raw materials in the water content of 10% to 30%. The choice of preparation method is based on the water content of the raw material leaving the mining field, the molding process, the quality of the landscape brick body, especially the particle size of the raw material and the type of product.
