Hollow Block Machine

Give you a brief history of hollow block manufacturing machines, Solid concrete blocks were first employed in 1832 by the builder William Ranger in England who patented his version of “Ranger’s Artificial Stone.” Several decades later in 1860, Hollow concrete blocks began to be used for wall construction.

However, in 1868, a builder named Frear founded what could be deliberated as the first stationary machine to build concrete blocks on the American continent. The current appearance of blocks was established when Harmon S. Palmer received its first U.S. patent for “Concrete Block Molding Machinery” in 1887.

Raw Material For Concrete Hollow Blocks

When speaking on Hollow Block Making Machine, you need to know some facts about the material used for these blocks.

As said earlier, the hollow concrete brick can be produced by hollow block making machine, and the product is mainly used to fill high-level framework because of its lightweight, sound insulation, good thermal insulation effect and others in its advantages.

  • Cement

Cement is a binder material, a substance used for the construction that sets, hardens, and adheres to other materials to bind them together. This is obviously the most important of all materials used in concrete blocks.

For your concrete blocks, it is advisable to always use a good cement from a good cement company. This is mainly to regulate aerated concrete slurry thickening time and to ensure a stable slurry casting.

Moreover, cement hydration, setting, and hardening can make your final product has a certain strength and better durability.

  • Fly ash 

Fly ash is a coal combustion product that is composed of the particulates that are driven out of coal-fired boilers together with the flue gases. Lately, methods of replacing partial cement with high-volume fly ash have emerged because of its ability to increase the workability of cement while reducing water demand.

You should note that concrete bricks are also essential to have low shrinkage values of other properties to have a high strength product.


  • Sand

Sand is a granular material composed of finely divided rock and mineral particles. As you know, sand is one of the most important raw material used for concrete blocks, and one of its uniqueness is that you can see it in large quantities from nature i.e., it is very common.

The quality and quantity of sand you use in the maker of your blocks determines the texture and hardness of each block.

  • Gravel material

Gravel is a loose aggregation of rock fragments. It is classified by particle size range and includes size classes from granules to boulder-sized fragments.

Gravel is an important commercial product, with a number of applications for the construction industry. You should note that small gravel are important for concrete hollow blocks.

The maximum particle size of gravel to be used for the successful maker of your hollow block cannot exceed 10mm。

The working system of a Block making machine is equal to the production of a Hollow block which involves four stages of manufacturing:

  1. Proportioning:

This is one of the most crucial aspects of blocks using the block making machine. It is the determination of the suitable amount of raw materials needed to produce the desired quality under given conditions.

According to academia.edu, the combined aggregate content in the concrete mix used for making hollow blocks should not be more than 6 parts to 1 part by volume of Portland cement.

If this ratio is taken in terms of weight basis this may average approximately 1:7 (cement: aggregate). However, there have been instances of employing a lean mix of as high as 1:9 by manufacturers where hollow blocks are compacted by power-operated vibrating machines.

The water-cement ratio of 0.62 by weight basis can be used for concrete hollow blocks. Contact us for more information including video and price now.

  1. Mixing

The thorough mixing of aggregates is important in hollow block maker machine. You must allow thorough mixing so that the water-cement paste will completely cover the surface of the aggregates.

The concrete mixer collects all the raw materials including water and rotates it for one and a half minutes (11/2). The product of the mixture is discharged into the mixer and consumed within 30 minutes, this prevents clinkers.

  1. Compacting

Compacting is the filling of air-holes with concrete particles without movement of water through the concrete. But if there are excessive compacting results in the formation of water pockets and layers with high water content and poor quality of product.

  1. Molding:

The wooden pallet is kept on the vibrating platform of the machine and the mold box is depressed on to the pallet. The mixed concrete is poured into the mold and evenly leveled. The motorized vibrating causes the concrete to settle down the mold by approximately 11/2 to 13/4 inches.

The stripper head is then placed over the mold to bear on the leveled material. Vibration causes the concrete come down to its limit position, then the mold box is lifted by the lever.

The blocks molded rests on the pallet and is removed afterward and another pallet is placed and the molding process repeated.

One of the keys featuring advantages of the block making machine is that it can accommodate different molds for producing blocks of different sizes.
