Working Principle

Working principle of feeding system: The feeding system will transport raw materials such as cement, sand, gravel, fly ash, etc. to the mixing system according to the pre-set ratio. For example, different raw materials are quantitatively fed into the mixer through belt conveyors, screw conveyors and other equipment to ensure that various raw materials can be accurately proportioned, laying the foundation for the production of hollow blocks with stable quality.
Working principle of mixing system: The mixing system is usually composed of a mixing shaft, mixing blades and a motor. The motor drives the mixing shaft to rotate, and the blades on the mixing shaft fully mix the raw materials entering the mixer. During the mixing process, add an appropriate amount of water to evenly mix raw materials such as cement, sand, and stone to form a concrete slurry with good plasticity and fluidity, ensuring that the slurry can evenly fill the mold in the subsequent molding process.
Working principle of molding system: The molding system is the core part of the cement hollow block machine, mainly composed of a mold and a pressure head, vibrator, etc. that cooperate with it. When the stirred slurry is fed into the mold, the vibrator will generate high-frequency vibrations to evenly distribute the slurry in the mold and remove the air in it, while squeezing and filling the particles in the slurry to achieve a preliminary dense effect. Then, the pressure head, under the action of the hydraulic system or mechanical device, applies a certain pressure to the slurry in the mold to further compact the slurry and form it tightly to form a hollow block body with a specific shape, size and pore structure.

Working Process

Raw Material Preparation

Raw Material Selection: Select cement with stable quality and suitable strength grade. Choose qualified sand and stone aggregates, and control their particle size and mud content. Industrial waste residues such as fly ash and slag, as well as admixtures such as water reducers and waterproofing agents, can also be prepared as needed.

Transportation and Storage: Use belt conveyors, screw conveyors and other equipment to transport raw materials such as cement, sand and stone to storage bins or hoppers for storage, facilitating subsequent batching.

Batching and Mixing

Accurate Batching: Weigh and batch various raw materials accurately through a batching machine according to the preset formula ratio. The batching machine is usually controlled by a computer, which can accurately control the dosage of each raw material according to different product requirements and types of raw materials.

Full Mixing: Feed the batched raw materials into a mixer and add an appropriate amount of water. The mixing shaft and blades of the mixer rotate to fully mix the raw materials, forming a concrete slurry with good plasticity and uniformity. This ensures that all raw materials are fully mixed, laying the foundation for the production of high-quality hollow blocks.

Molding

Mold Preparation: Select a suitable mold and install it on the molding machine according to the required shape, size and specification of the hollow block. The mold should have sufficient strength, rigidity and wear resistance to ensure the quality and accuracy of block molding.

Slurry Feeding into the Mold: Transport the mixed concrete slurry to the mold of the molding machine through a feeding device. Belt conveyors, screw feeders or hydraulic feeding devices are usually used to ensure that the slurry is evenly filled into the mold.

Vibration Compaction: Under the action of the high-frequency vibration of the vibrator, the air in the slurry in the mold is discharged, and the particles in the slurry are squeezed and filled with each other to achieve the effect of initial compaction. Meanwhile, under the action of the hydraulic system or mechanical device, the pressure head applies a certain pressure to the slurry in the mold to further compact the slurry, making it closely molded into a hollow block blank with a specific shape, size and hole structure.

Demolding

Demolding Operation: After the hollow block is molded and reaches a certain strength and hardness, the demolding system starts to work. The demolding system is generally realized by a hydraulic device or a mechanical device. The hydraulic cylinder is used to push the demolding mechanism to separate the mold from the molded block, and the block is ejected or pulled out of the mold to complete the demolding process.

Block Output: The demolded hollow blocks are transported to the designated position through a conveying device such as a belt conveyor or a chain conveyor for subsequent curing and processing.

Curing and Palletizing

Curing Treatment: Put the molded hollow blocks into a curing room or curing site for curing. The curing methods include natural curing and steam curing. Natural curing keeps the surface of the blocks moist at normal temperature, allowing them to reach the designed strength within a certain period. Steam curing accelerates the hardening process of the blocks and shortens the curing time by introducing steam to increase the temperature and humidity of the curing environment.

Palletizing and Stacking: After the curing is completed, the hollow blocks are inspected for quality. The qualified blocks are palletized and stacked by a palletizer or manually for storage and transportation. When palletizing, pay attention to the stacking method and height of the blocks to avoid damage or collapse of the blocks.

Finished Product Storage and Transportation

Storage Management: Store the palletized finished hollow blocks in warehouses or open storage yards. During the storage process, pay attention to measures such as moisture prevention, sun protection and rain protection to prevent the quality of the blocks from being affected by environmental factors.

Transportation and Distribution: According to customer requirements, use loading and unloading equipment such as forklifts and cranes to load the hollow blocks onto transport vehicles and transport them to construction sites or other usage sites. During the transportation process, ensure the stability and integrity of the blocks to avoid damage during transportation.
