    Companies tend to product quality win, unburned in the production process, quality and closely related to each process, so to maintain a strict quality control of each process.

        Crushing and screening of raw materials, to strictly control the particle size distribution of raw materials, the oversize material back from the new crusher for re-crushing. Raw ingredients into the car must be sifted, screened out unqualified coarse particles.

        According to local soil conditions, a reasonable choice mix. Weigh in strict accordance with the ratio of the amount of various materials, particularly cement materials, such as cement dosage should be weighed, not less, only more so as to ensure the quality of bricks children.

        Stirring the mixture, be sure to control the cement and clay (or lime and clay) together dry mix, time is generally 2-3 minutes, is easy to make because of the dry mix cement evenly dispersed in the soil. Then add wet mix for 2-3 minutes. Cement block to control moisture at about 10%. If uneven mixing, make bricks without some low-strength cement or adobe bricks small amounts, then formed. Easily weathered. When dry mix, experienced operatives, head side to see the available mix, even if the mixture stirred color, do not see the pure soil material, then stir, you can add water. Instead, mix up the colors very uneven dish, mix the cement does not open, it should continue to stir until the uniform color.

        Molding process should pay attention to two points, one from the hopper down to mix evenly fills the mold box, the mixture in the mold box can not be side higher. To adjust the height of the packing machine is good, high tonnage PRESS, the packing height is higher, the greater the intensity of the pressure out of the bricks, the second is pressed into a brick mold box from the top of the post, while taking bricks, operating workers should always carefully observe whether the fine cracks of the brick surface, because some small fine cracks. Such as continuous discovery of cracks, adjust the mix mix, should be added to the aggregate number of coarse particles, such as adding sand particle size less than 2mm. If adding sand, bricks as well as crack, then the machine exhaust is not, to adjust the machine speed, slow the speed of the machine, you can eliminate the cracks. Molding process is an important aspect of the waste will not pay attention.

       Finished curing processes. Cement Pastes finished before the factory generally require two weeks after the Nature Conservancy. Not subject to direct sun and rain during the curing Lynn. No yard shed, covered with plastic sheeting can be used on grass or brick.

        When the brick factory, the product must be tested. Test methods and standards, according to national building materials industry standard "non-sintered rod through dry adobe" execution (see Appendix 1). Test results must be documented, archived as technical information. Pastes to 28 days as a standard strength, the strength is less than 28 days or more tiles are used as reference. According to the test results, and to determine the grade level of the brick. Bricks were piled should level and indicate the date of manufacture. Transport loading and unloading at the factory, is strictly prohibited throw, collision avoidance beaten, not allowed to use dump trucks dump.
