Hollow Block Machine


Hollow block



In some countries, it is called brick too and the machine, of course, is called brick making machine. It is also called block making machine and paver block machine as well. These are common names used for this machine, but the original name hollow block machine is more common.

A hollow concrete block is made of concrete, there are different standards of the mixture ratio of the mortar that is used to make hollow concrete blocks and there are different additives for the mortar as well. The mixture ratio determines the resistance and other characteristics of the hollow concrete block. Another factor is water, if it is drinking quality water it won’t cause any troubles but using low-quality water with many minerals dissolved in it can cause some white lines and spots appearing on the block when it is dried. These blocks are usually used to build walls and they are covered with plaster or other covering products almost in all cases, so it won’t be a big problem if your water doesn’t have good quality.

You may ask why we need these hollow spaces in blocks. Actually, it is because of air, air traps winter's colder temperatures or summer's heat between the walls of hollow concrete blocks and forms a barrier that blocks the heat and cold from affecting your home. So, you will spend less energy to reach the temperature you desire. Below you can see a hollow block sample.





Hollow block machine types and capacities

There are generally two types of hollow block machines:


The stationary hollow block machine is a bigger machine compared to the mobile hollow block machine, it has a large production capacity and of course, it is built in different capacities as well.

The capacity of the hollow block machine has an international standard:

The number of standard blocks that a hollow block machine can produce in one press determines the standard of the hollow block machine. Here are some examples:



  • A hollow block machine that produces 12 pieces of hollow concrete blocks in one press is called PRS-1200. 



The minimum capacity of the stationary hollow block machine is 4 pieces of blocks in each press. It is called PRS-400.

Necessary elements for establishing a hollow block factory

 1. Land dimension:



It is recommended to buy bigger lands if it is possible in your country because you may develop your business in the future and buy a ready-mixed concrete batching plant for construction purposes or even develop your own hollow block machine and add robots to your interlocking brick machine. In this case, you won’t need to buy land if you have enough budget to buy it in the first place. Different names are used for the hollow block machine, like interlocking brick machine or paver block machine to make you more familiar with the different names of this machine based on the use.


 2. Ingredients:


1. Powdered Portland cement

2. Reasonable quality water

3. Sand

4. Gravel

This is the basic ingredient list for the mortar that is feed to your hollow block machine. In some countries the ingredients are different but the size of the ingredient should be below 5mm. The most expensive material above is cement. It is stored in cement silos and added automatically in the automatic model and it is stored in 30kg packages added by hand in the semi-automatic model.





3. Labor force:


If the labor cost and land are expensive in your area, we recommend you buy an automatic hollow block machine.

 4. Hollow block machine:

The machine has different names, it is called hollow block machine, brick making machine, hollow block making machine, even brick laying machine. They all mean the same. It is very important to choose your machine wisely, the machine you choose should be able to produce hollow concrete blocks, paving blocks, tiles, roof gutters, curbstones, Asmolen and lawn stones by changing the molds.




Some of these hollow block machines are designed double-hopper system. The second hopper is for producing double-layered paving blocks and it doesn’t affect hollow blocks and it is explained in another article related to the paving blocks.

Below you can see the production process of hollow blocks. You can also visit our youtube channel for both animation and real videos.



5. Budget:

You should spend your budget wisely. You shouldn’t spend your whole budget buying the block making machine. Considering the expenses like shipment transporting the machinery and its insurance, using a lift to place your machine, buying aggregate and paying the personnel for a few months if you are selling your products in installments is very important.


 6. Electrical energy:

As the calculations show 20% to 30% of each hollow concrete block is profit. It depends on the country and the expenses of each country too, but this percentage is normally true. You can start your company by less budget by buying a semi-automatic hollow block machine and upgrade it in the future if you buy a machine which is upgradable.
