Paver block machine

Paving Blocks


First, we need to have detailed information about paving blocks, then we can talk about paver block machines also known as interlocking brick machines.

You may ask What a paver block or interlocking block is, paver blocks are manufactured to be laid on the floor, they are made of different materials with different shapes.

Paving blocks are made of different materials in different countries but generally, they are made of the materials below:

  • Powdered cement
  • Water
  • Crushed stone
  • Sand
  • Additives

Paving Block Advantages


The benefit of paving block over other materials is that each individual paving block can later be lifted and replaced, also they are cheaper compared to other materials.

Paver blocks are formed in paver block machines. These machines use vibration and pressure in the molds to form the paver blocks. So they also bear more pressure compared to other materials.

Note that block making machine and paver block machine are different from each other. A paving block machine is a double-hopper machine that can produce double layer blocks, but a hollow block machine is a single-layer machine that can only produce single-layer blocks. If you are interested in this subject you can read our article hollow block machine or concrete block machine.

Both of these machines can almost produce 600 different shapes including hollow concrete blocks, paver blocks, solid blocks, curbstones, roof gutters, lego blocks, and etc. So don't get confused when you hear different names:

  • hollow block machine
  • block making machine
  • paving block machine
  • concrete block machine
  • interlocking brick machine

Paver Block Machine Mold


A concrete mold is a metal hollow container that is made of high-quality steel. For paver block machine each mold has two pieces

  • Upper mold
  • Down mold

They are also called male and female molds. The down mold has hollow spaces and the upper half fills the gaps of the down mold. When the upper mold comes down it fills the hollow spaces on the down mold. Hydraulic power is used to make movements in the machine.

High-quality molds for paver block machines have a guarantee of about 60.000 to 80.000 presses. When you pour mortar in the down mold of the paving block machine and press the other upper half to it with pressure and vibration the concrete takes the shape of the mold.
Mostly ST-53 or Hardoax metal sheets are used to produce concrete molds.

Some of the available molds are:

  • Hollow concrete block molds in different sizes and shapes
  • Different Paving blocks with different dimensions, thicknesses, and shapes
  • Different types of curbstone molds
  • Asmolen molds
  • Tile molds

To purchase a mold for your machine, you need to ask a mold manufacturer to produce it for you. We also produce all types of molds you just need to contact us. It normally takes 2 to 3 weeks to produce a high-quality mold. It is because of the cutting shaping and two times of hardening and machining as well.
If you are interested in knowing more about molds or order your mold you can also contact concrete block molds.

Interlocking Paving Blocks


Interlocking means they lock each other when they are laid on the ground. The idea of interlocking paving blocks originated in the Netherlands. They replaced the brick on the surface of the streets with paving blocks for the first time. At that time there was no paver block machine and they have produced them manually and by hand.

These paving blocks are more durable than asphalt, easy to repair and maintain. Paving blocks are even resistant to earthquakes. If you are interested to learn more about this subject you can read our article interlocking brick machine.

 

Paver Block Machine


 Generally, we have two types of paver block machines as explained below.

  • Single-hopper machine:

The single-hopper machine can only produce single-layered paving blocks. This means if you want to have a smoother surface you need to apply it to the whole mortar of the paving block. If you also need colored paving blocks, again you need to color the whole mortar of the paving block. This will charge you extra costs to the final price of the paving blocks compared to the double-hopper paving block machine. Single-layer machines are also called brick making machines or block making machines.

  • Double-hopper machine: 

The double-hopper machine has two mortar hoppers, it enables you to produce double-layered blocks. The first layer is the coarse main mortar and the second layer is the surface of the paving block. You only need to apply your desired quality to the top layer. The upper layer can have different thicknesses and different colors depending on customer demands. These machines are also called paving block machines.

Paver Block Machine Capacity


As mentioned above the paver block machine is a machine that can produce different concrete products like concrete hollow blocks, paving blocks, curbstones, asmolen blocks, tiles and roof gutters. You only need to change the molds in order to produce different products.

To calculate the capacity of the block making machine there is a standard way. The capacity of the paver block machine is determined by how many square meters it can produce in 8 hours. the smallest machine produces 300 m2 in an eight-hour shift. If you need to determine the paving block machine’s capacity in the total number of paving blocks that it produces, you need to know that in each square meter of the paving block there are normally 36 paving stones.

In the table below you can see the production capacity of different machines:

Paver Block Machine Production Process


To produce paving blocks, first, you need to provide your paver block machine with aggregates like cement, water, sand, and additives. They are stored in special compartments with an unloader cover under them. By this container and the weighing conveyor belt, they are weighed and then delivered to the mixer of the machine.

 

 

Cement is also stored in cement silos and water is added through a pump and a digital counter. The water is measured by liter when it is being added to the mixer. In the mixer, all the materials are mixed and after the water is added to them, they form the mortar needed for the machine. This mortar has a standard ratio for each of the ingredients.

It is important to add the materials by the standard ratio because it affects the strength of your product and saves you money as well by using the right amount of cement. Cement is the most expensive ingredient in the mixture needed for the interlocking brick machine.

The mortar is then carried to the hopper of the paver block machine. If you have a double-hopper paving block machine then the same process takes place again and this time additives like color are added to form the upper layer.

There is an unloader cover on both hoppers that lead the mortar to the mold cart. This part of the machine moves above the mold to fill the mold with the mortar. After it fills the mold with mortar, vibration takes place to fill the small gaps in the mortar. By vibration, the mortar shrinks and it should be filled again. For this reason, the mold filling machine moves back and forth again to fill the mold for the last time.

Some paver block machines do the filling process and vibration at the same time to save time in the process.

When the mold is filled with mortar for the second time it is time for the hydraulic press of the concrete paving block machine to push the upper mold to the down mold with 120 bars of pressure.

The press is done over the surface of the pallets. After the mortar is formed, both molds move up so the pallet can be delivered out.

Talking about the pallets for the concrete block machine, they are optionally made of wood, metal or plastic. They have different sizes related to the capacity of the machine. The smallest pallet is 50cm in width 100cm in length and with a thickness of 4cm. The pallets with the products on them are then delivered to the curing section. This can be done whether manually or automatically.

Pallet System of The Machine


The pallet input system differs in manual and automatic paver block machines as well. In the manual system, the products should be collected from the surface of the pallets by hand and then pallet should be placed in the pallet feeding robot of the paving block machine.

In the automatic system, after the products are dried you first need to put them in the pallet feeding system in the paver block machine, then they are divided and they come out on the rails of the machine one by one. This is where the products are collected by hand or optionally by a robot and then the pallet is guided to the press of the concrete block making machine. Then the cycle repeats itself again.

In the manual system, the pallets are taken to the curing section with special handcarts and it is done one by one while in the automatic system five of them are collected on top of each other by the paving block machine then they are carried to the curing section by a forklift.

It is recommended to buy automatic paver block machines for the countries that the land and labor costs are expensive because the automatic system requires fewer workers and less curing area. For the countries that land and labor cost are cheap, the manual system serves better. Here is a video of one of our paving block machines. for more videos, you can also visit the Bess youtube channel.
