In the brick making process, the particle grading of the raw materials has a great influence on the grade of the product, the smaller the particle size is, the finer and more compact the product is, and the better the strength and other properties are, so in the actual production, the raw materials are often crushed into powder to improve the grade of the product. But powdered raw materials can produce the raise dust in mixing the in-process, seriously threatens personnel's healthy, makes powdered material contain certain moisture and can effectively reduce the raise dust, but the moisture content height can cause powdered raw materials agglomeration serious, can't make effectual dispersion mix between the different raw materials, can't make the product that the texture is homogeneous.

After the premixed raw materials enter the kneading bin 1 through the feeding hole 2, the materials are pushed and extruded towards the discharging hole 3 through the rotation of the main kneading roller 4 and the secondary kneading roller 5, the roller surfaces of the main kneading roller 4 and the secondary kneading roller 5 are close to but not in contact with each other, so that the agglomerated parts of the materials can be crushed in the pushing and extruding process, the kneading nails are arranged in a staggered mode, the materials can also move perpendicular to the surfaces of the main kneading roller 4 or the secondary kneading roller 5 in the moving process towards the discharging hole 3, the position moving states of the materials in the pushing and extruding process are different due to different positions of the materials, the originally agglomerated materials are fully mixed, meanwhile, the materials are extruded by the roller surfaces and kneaded by the kneading nails in the pushing and extruding process, and chemical reactions can occur on the surfaces of material particles, so that the affinity among the materials is improved, the materials are cured in the process, the product sintered by the treated materials is finer than the product made by the same-grade materials according to a common method, the internal prestress of the product is small, the product is not easy to crack, and the strength is also improved.
