Cement brick making machine is a mechanical equipment that utilizes industrial solid waste materials such as fly ash, slag, slag, and construction waste to convert them into high-quality bricks through a series of process steps. The following is the detailed production process of cement brick making machine:

1、 Raw material selection and preparation

The production process of cement brick making machine begins with the selection and preparation of raw materials. These raw materials usually include industrial solid waste as well as appropriate amounts of cement, sand, rice, stone, etc. The selection of raw materials requires strict control over their quality and ratio to ensure the quality of the final product.

Industrial solid waste, such as fly ash, slag, slag, and construction waste, needs to be screened and classified to remove impurities and ensure the purity of raw materials.

Cement: Ordinary Portland cement is preferred, with a strength grade of 32.5Mpa and a storage period of no more than three months.
Sand: yellow sand with a fineness modulus of 2.0-2.5 shall be used, and its mud content shall not exceed 5%.

Rice stone: It should comply with the provisions of GB/T14685, and should use crushed stone with a maximum particle size of 0-6mm. Its mud content should not exceed 1.5%, and the mud block content should not exceed 0.7%.

2、 Raw material crushing and grinding

After screening and classification, the raw materials need to be crushed and ground for better mixing and shaping.

Crushing: Use a crusher to crush the raw materials to ensure that their particle size meets the requirements for brick making.

Grinding: The crushed raw materials are sent to the gypsum silo for grinding processing, and the fineness of the processed raw materials needs to meet the requirements of the brick making process.

3、 Ingredients and Mixing

Batching and mixing are key steps in the production process of cement brick making machines.

Ingredients: A computer-controlled batching machine is used to automatically measure and transfer different raw materials and formulas into the mixer.

Mixing: The mixer is suitable for forced mixing of various concrete product materials. The mixing time needs to be strictly controlled, with dry mixing not less than 1 minute and wet mixing not less than 2 minutes. During the mixing process, water should be added according to the moisture content of the sand to ensure that the mixed material meets the production requirements.

4、 Forming and Pressing


The mixed material is sent to the molding machine for molding and pressing.

Molding: The molding machine adopts PLC computer intelligent control, and randomly adjusts parameters according to the needs of producing different products and materials. During the molding process, the material undergoes vibration and pressure molding inside the mold to ensure the consistency of the product's density and height.

Pressing: The molding machine uses multiple pressurization and exhaust processes during the process of pressing the brick blank, ensuring that the air contained in the powder is smoothly discharged during the pressing process, ensuring high strength of the brick blank and avoiding the formation of cracks.

5、 Demoulding and maintenance

The formed brick blank needs to be demolded and cured.

Demolding: The formed brick blank is demolded through a demolding mechanism. The demolded brick blank needs to be checked for slight missing corners, missing materials, cracks, and other phenomena. If there are any, manual on-site repair can be used.

Maintenance: After demolding, the bricks need to be cured, usually by watering. The maintenance time is adjusted according to the season and weather conditions to ensure that the bricks fully harden and solidify during the maintenance process.

6、 Packing and stacking

The finished bricks after maintenance treatment need to be packaged and stacked.

Packaging: Use a palletized packaging unit to package finished bricks, ensuring that they are not damaged during transportation and stacking.

Stacking: The packaged finished bricks are transported to an open space for stacking and waiting for shipment. During the stacking process, attention should be paid to the stability and safety of the bricks.

7、 Equipment maintenance and oil temperature control

In the production process of cement brick making machines, equipment maintenance and oil temperature control are also very important links.

Equipment maintenance: Regularly maintain and upkeep the equipment to ensure its normal operation and extend its service life.

Oil temperature control: Friction heat is generated during equipment operation, leading to an increase in oil temperature. In order to prevent damage to equipment caused by excessive oil temperature, a series of measures need to be taken to control the oil temperature, such as increasing cooling facilities and maintaining oil cleanliness.
