Hollow Block Machine: Definitive Guide

Introduction:

Hollow Blocks are concrete blocks universally used in compound walls due to its low cost. These hollow blocks are more advantageous due to its lightweight and ease of exposure to air.

The blocks and bricks are made out of a mixture of cement, sand, and stone chips.

Typically the size of Hollow blocks are definitely following: 40cm(length) X 20cm(width) X 4 in(thickness) or 40cm(length) X 20cm(width) X 5 in(thickness). In general, a hollow-core concrete block is more than 50% solid.

A typical Hollow block

So in this article, you will be enlightened as we will be looking deeply and extensively into a Hollow Block Machine.

And Hollow Block production using your Hollow Block maker.

What is hollow block making machine?

A hollow block machine can be simply defined as a machine specially designed for the production of a hollow block. This type of machine can produce hundreds to thousands of hollow blocks in a very short time.

Hollow bricks making machine makes production easier for you as a producer of hollow blocks.

Because it requires less man-power and working hours and machine users have reviewed this that it can make your total production cost lesser.

Before the production of Hollow Bricks Plant, production of hollow blocks using traditionally inspired machines causes environmental pollution, which is as a result of the dangerous fumes they release into the air.

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 the first stationary plant 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.

Today you can see that Hollow Block machine has proven itself to be economically active and has been able to vanquish the fear consumers have when using blocks.

Raw Materials Used For Hollow Blocks

When speaking on Hollow Block machines, you need to know some facts about the materials used for the production of these Hollow blocks.

As said earlier, the hollow concrete block 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, 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 the production of modern blocks.

In the production of your hollow concrete blocks, it is advisable to always use a good cement from a good cement production 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 in the production of hollow concrete block, it is also essential to have low shrinkage values of other properties to have a high strength product. Therefore, you should use the fly ash, which is more fineness to give a better product as your output.

Sand-for-hollow-block

  • 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 materials used for the production of Hollow 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 production of your hollow blocks determines the texture and hardness of each block.

  • Gravel

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. You should note that both sand and small gravel are important for the production of concrete hollow blocks.

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

Advantages Of Hollow Block Machine

Concrete Hollow Block machine has major advantages as follows:

  1. High Strength of Block:

The effective hydraulic pressure systems present in your Hollow Block making machine produce each unit with high precision and accuracy.

You also get blocks which are highly rigid, vibration resisting and of high strength by the provision of close-grain structure to the block by the machine.

  1. Customizable:

The requirement of the design of block differs highly depending on the construction needs. Modern automatic hollow block making machines are integrated with advanced control systems which let you change the molding design as per the needs.

That is, you can customize the shape of your hollow block or even inscribed on it. Also, switching the machine between fully automatic and semi-automatic is also a possibility in these machines.

  1. Quick and Accurate:

Production rate per time of hollow block making machine really reduces the overall production time of hollow blocks. The hollow block machine was designed to give the fastest production you can ever imagine. Now, you can have 8000 blocks produced within a few hours using the hollow block making machine.

Obviously, this speed of production has proven useful in a variety of construction projects. Features that made the production of hollow blocks faster than others are; Because of hydraulic pressure systems, quick feeding system, quick molding cycles, and high production efficiency.

All these make the hollow block making machine preferable.

  1. Environment-Friendly:

Hollow block machine is very advantageous to the environment because it surmounts the pressure given by the enormous flame given off by other traditional block making machines.

Also, since hollow brick making machine makes use of industrial wastes like fly ash and other similar waste, it serves as a medium for the recycling of industrial waste which ultimately serves for the betterment of the environment.

  1. Low cost of hollow blocks:

Hollow brick machines are innovated so that they can reduce up to 40% of energy usage and this helps reduce the overall production cost on your part and also the low cost of hollow blocks on the consumer part.

  1. Efficient use of resources:

When talking about the advantages of a hollow block making machine, its efficient use of your materials/resources cannot be over-emphasized. In the use of your hollow block machine, your raw materials are precisely mixed in your desired ratio and proportion.

This means that with every kilogram of the raw material cab is accounted for in the production of the blocks, which is quite economical.

Working System of Hollow Block machine

The working principle of block making machine is to use slag, mine slag, pulverized coal ash, stone powder, industrial sand, industrial stone, industrial cement and other materials as raw materials, scientific ratio and water mixing and finally through the new type.

The concrete block making machine is pressed at high pressure so that beautiful cement blocks and hollow blocks can be pressed and colored pavement blocks can be manufactured.

The working system of a Hollow 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 in the manufacture of hollow blocks using the Hollow 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.

  1. Mixing

Thorough mixing of aggregates is important in production. 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 is excessive compacting results in 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 levelled. 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 levelled material. Vibration causes the concrete come down to its limit position, then the mold box is lifted by the lever.

The hollow blocks molded rests on the pallet and is removed afterwards and another pallet is placed and the molding process repeated. One of the key featuring advantages of the hollow block making machine is that it can accommodate different molds for producing blocks of different sizes.

  1. Conclusion

LONTTO hollow block machine working principle: the materials are mixed by concrete mixer, semi-automatic type machine need JQ350 mixer, Full type machine need JS550, JS750 concrete mixer. Then the materials are transferred to the hopper by belt machine. Then materials are distributed to the bottom mold. The upper mold press down according to the hydraulic press and strong vibration motors. After a few seconds, the hollow blocks are produced.

Maintenance of A Hollow Block Making Machine

You as a good manufacturer must be ready to take part in the maintenance of your Hollow block machine because by proper maintenance, your machine will have a long lifespan.

  1. Removing concrete residue when cleaning the mold requires the use of air compressor and soft tool. Do not heavily knock, pry and scrape the mold.
  2. When you want to install or change the mold of hollow brick machine equipment, collision should be avoided. Damages and deformations occur when there is mold and mold collision, mold and other parts collision and these must be avoided.
  3. Carefully adjust clearance, including the space of head and the mold core, head and sport plane, mold frame and line plate. Relative motion shall not interfere and brush touch
  4. You must check the condition of the mold size and welding combining site in use. If weld cracking occurs, you must speedily repair.

When you replace the old, you should clean and oil the rusty metal surface. Then you should flat it in dry and level off place to avert the gravity distortion.

How to buy a Hollow Block machine?

Investing in a hollow block making machine is a smart decision for any business that is looking to get off the ground quickly by producing high-quality products with a low overall production cost.

There are some laid down check-ups you must do when you are buying your hollow block making machine:

  1. The steel: It is always important to check the type of steel that was used to make the machine because it dictates the life of the machine. The quality of the steel used in some machines makes them use 30-40 years and will still be in operation. So it is always advisable for buyers to check this when buying.

  1. The pressure system: This part of the machine must be very strong and well built in order to produce blocks with high quality. When the pressure system of a hollow block making machine is not strong, blocks can be cracked and this causes collapsing before and after final production of blocks.
  2. Concrete mixing unit: This is the heart of the block making machine. If the machine is the brain and the brain can’t work without the heart, so a block making machine cannot work well unless the concrete mixing unit is very much okay. When buying a hollow block making machine, you have to check the quality of the concrete mixing unit.
  3. Have a plan for the machine: Always have a plan on the maintenance of any hollow block making machine you want to buy. Do your homework on any product, ensure to have a business plan and be realistic in your expectations.

Production time: When buying a hollow block making machine, you have to look into this critically. The production time of a machine affects production in a great deal. It determines the number of blocks to be produced within working hours.
