Cement brick making machine


Cement Brick Making Machine


Generally, a cement brick making machine is a machine that uses vibration and pressure on the mortar and molds to produce hollow concrete blocks. This machine is also called a hollow block machine and has different automation levels and different capacities. We will discuss them one by one in this article.

You may ask why cement is used instead of concrete in the name. It is because usually, people don’t know the difference between concrete and cement, Cement is the powder that is used with other raw materials and water to form the concrete in the shape of mortar. 

About the brick, this is true as well. Before hollow blocks, people only used bricks and when these hollow blocks were created, people started to call them the cement bricks. It is not a correct name but it is commonly used.

People also call these machines in different names when they produce different products. For example, when the block making machine produces paver blocks it is called a paver block machine.

When the machine produces hollow blocks it is called a hollow block machine.

The other difference between these two machines is that hollow block machines are single-hopper machines and paver block machines are double-hopper machines. You can click on their names to read more information about them.

Cement Brick Making Machine types


Brick making machines have different types but globally it is categorized into two main types

  • Mobile brick making machine
  • Stationary brick making machine

 

Mobile Brick Making Machine


A mobile brick making machine is also called the bricklaying machine. It is way simpler than the stationary cement brick machines. It is cheaper as well, but the capacity and mold options are lower as well. This machine is capable of moving after it lays the bricks.

Talking about the pros and cons, this bricklaying machine moves after it lays concrete blocks. This machine doesn’t need pallets. It produces the hollow blocks on the ground, this is an advantage but every machine in the world has its disadvantages as well. This machine is not a paver block machine it means it cannot produce concrete paving blocks and the capacity is low compared to stationary cement brick making machines.

The capacity of the mobile brick laying machine is between 2225 and 3750 pieces of standard hollow concrete blocks in eight hours.

The standard hollow block is a block with the dimensions 20cm(W) x 40cm(L) x 20cm(H)

This machine is manufactured in three different types as shown below:

The main difference between these cement brick making machines is their speed. The full-automatic brick making machine can produce faster than the other machines but it’s a little bit expensive as well.

Totally to operate this cement brick making machine you need 4 workers on the field, one worker will operate the machine, two workers supply the mortar needed for the machine and one delivers mortar from the mixer to the machine.

The capacity of the mobile brick laying machine is shown in the table below:

 

Machine Name Size 3 Machine Size 4 Machine
Manual Brick Laying Machine 2250 Hollow Blocks 2750 Hollow Blocks
Semi-Automatic Brick Laying Machine 2500 Hollow Blocks 3250 Hollow Blocks
Full-Automatic Brick Laying Machine 2750 Hollow Blocks 3750 Hollow Blocks

Stationary Cement Brick Making Machine


As the name represents this machine is stationary. It is designed to produce different capacities and different types of concrete products. This machine uses pallets and molds to produce cement blocks.

First, aggregate is transferred to the field to supply the cement brick making machine then the machine automatically or manually delivers this aggregate to the mixer. Water and cement are added to the mixer in this step, then the mortar is formed. Mortar is then delivered to the machine and the machine uses molds and pallets to produce hollow concrete blocks. we use Siemens plc in our machines.

When concrete blocks are formed, they need to get dried before they can be used.

To transfer the pallets to the drying section two choices are available:

  • Manual pallet collecting system
  • Automatic pallet collecting system

Each of both has advantages and disadvantages over another, manual pallet collecting system is cheap and simple, but it required more space to get dried because pallets are collected and delivered one by one, it consumes more time as well because it is done manually and slowly.

On the other hand, the automatic pallet collecting system is more expensive but it is done by robots that are mounted on the stationary
concrete block machine. Pallets containing the produced wet blocks are first stored on top of each other, when they reach five, they are delivered to the drying section to get dried. By this system, you need less space for the drying section (five times smaller). Then the dried pellets are brought to the pallet feeding part of the machine and a robot takes the dried concrete blocks and delivers them to the euro pallets. It is true that the automatic cement brick making machine is expensive, but the advantages far overweigh the price.

Stationary cement brick making machine has some special options which can be added when ordering. for example, you can add a second hopper for the machine. with this option, you can produce two-layered paving blocks with different colors to make the paving blocks or other products more appealing. this machine is also called the paver block machine.

The smallest stationary cement brick making machine can produce 4 pieces of standard hollow blocks in one press. standard block means a block with the dimensions of 20cm*40cm*20cm(height). This machine is called PRS-400.

The next stationary cement brick making machine can produce 6 pieces of standard hollow blocks in one press. this machine is called PRS-600.

There are bigger sizes as well. The biggest size of the stationary machines is PRS-2400.

The smallest stationary brick making machine can produce 4000 pieces of hollow concrete blocks and The biggest stationary cement brick making machine can produce 24000 pieces of hollow concrete blocks in eight hours.

The mortar Used In Producing Hollow Concrete Blocks


The basic mixture of the mortar is 4-to-1 or 5-to-1 mixture. It means for every five parts of sand you need to add one part of cement and then you should add water until it you achieve the texture you want for your cement brick making machine. To produce a mixture that can be used in a cement brick machine you generally want a thick, creamy mixture that will stick but also endure the blocks' weight.

When adding water, you need to be more careful because too much water will make it difficult for the sand particles to bond with cement in the concrete.

You should also be careful with the amount of cement you are using for your cement brick making machine. to much cement will cause cracks on the hollow concrete clocks when they are dried. you can sometimes go as low as three shovels of sand to one shovel of cement, anything beyond that does not provide you with a quality mortar that cures slowly and hardens the best.

Sand helps the hollow concrete blocks to withstand the weight of the wall. So make sure you use the right ratio in your mortar.

These days it is very important to make hollow blocks lighter in weight.

It can be achieved by mixing a lighter aggregate, such as perlite, vermiculite, or Styrofoam to reduce the overall weight.

Like always it has advantages and disadvantages. It is not as strong as the old mixture but it has better insulation than the traditional concrete.

 This concrete is often used for countertops and rooftop decks, where a lighter weight is more important than a higher strength. it is also used for walls where insulation is more important than strength, such as offices.
