Lontto has over 30 years of experience providing worldwide brick and block-making machine solutions to construction projects. We’ve written this article to help you understand what a concrete block-making machine is, the different types of machines, and the manufacturing process.

What are the Core Features of Concrete Block Making Machines?

The core features of a concrete block machine include those used to mix concrete block ingredients, mold them into your desired block, and various control systems to allow you to alter the production process. The five main features of any concrete block-making machine are:

• Material handling system
• Mixing unit
• Molding system
• Compression mechanism
• Control system

What are Different Types of Concrete Block Making Machines?

The two types of concrete block-making machines are stationary brick-making machines and mobile block-making machines. Each type of machine is used for specific production niches, depending on the remoteness of your project, the production rate required, and your budget.

Stationary Block Making Machines

As the name suggests, stationary concrete block-making machines are typically immovable. They offer a high production rate, especially for the relatively small size they can occupy (around 800 square feet to 1,700 square feet). This makes a stationary block machine an excellent option for a construction project that requires more concrete blocks.

A stationary block-making machine uses a hard concrete floor for support, which may incur additional costs if your warehouse doesn’t include one. Stationary block-making machines also allow you to produce from more molds than mobile machines, including pavers, hollow blocks, and curb stones. In addition to variety, stationary block-making machines provide consistent, high-quality concrete partly due to automatic weighing systems.

Mobile Block Making Machines

Building a temporary stationary concrete block-making machine for your production needs is often time-consuming and costly if your construction is outside significant settlements and cities. Mobile block-making machines offer the versatility to move your production anywhere you need without pallets or heavy foundations.

You do have a tradeoff for this mobility, which comes in a reasonably simple working mechanism and production rate. Less capacity and fewer options for molds mean that mobile block-making machines excel in construction that has a limited budget, prolonged project time, and additional labor to help assist in the production process.

What is the Manufacturing Process of Block Machines?

The manufacturing process of block machines includes preparing the raw material mixtures into precise ratios to form concrete, transporting it to form blocks using concrete molds, and finally, curing the bricks to increase their strength and durability.

Material Preparation

Before producing your concrete blocks using block machines can begin, you must prepare the materials beforehand. The raw ingredients of cement blocks include Portland cement, sand and aggregates, and water. The cement acts as the primary binder of the block, which can be colored with additives and pigments.

The ingredients are mixed in a specific ratio, typically 1 part cement to 2 parts sand and three parts aggregate. Water is between 40% to 60% of the mixture’s weight.

Production Steps

Once the mixture is adequately prepared, you must ensure your concrete block-making machine works. Check if the vibration frequency is between 2,800 to 4,500 RPM, the hydraulic pressure is set for high compression, and the cycle time is between 11 to 25 seconds per operation.

What are the Production Capacities of Different Block Machines?

Concrete block-making machines have different production capacities, whether manual, semi-automatic, or fully automatic. Here is the production rate for each type of block machine:

• Manual: 2,250-3,750 blocks/8 hours
• Semi-Automatic: 4,000-12,000 blocks/8 hours
• Automatic: Up to 24,000 blocks/8 hours

Curing Process

The curing process for your blocks will depend on which curing technique you use for your blocks. These include wet, steam, membrane, or chemical curing.

In most cases, blocks will achieve 70% of their strength by day 7. This is why specific standards like the Federal Highway Administration Research and Technology require you to cure your blocks 7 days after placement.

Quality Control

Quality control is not the final step but the continuation of checks and balances throughout the concrete block-making machine process. This is essential for record-keeping, including material testing, production parameters, quality control measurements, and machine data.

A concrete block-making machine becomes an essential pillar for your construction project if you properly control the quality and quantity during the production process.

FAQs on What is a Concrete Block-Making Machine?

What mixes concrete in transit?

Transit-mixed concrete is mixed in a rotating drum mounted on a truck during transportation to construction sites. This ensures they're continually mixed during transport at a medium speed to reduce the chances of overmixing or the concrete beginning to set.

How many blocks can be produced in a day?

High-end models can produce around 18,000 concrete blocks every 8 hours, which is only possible by automatic block-making machines. This can be affected by using a hydraulic concrete block-making machine, worker availability, and the quality of raw products.

Understanding Cement Brick Making Machines

Cement brick making machines automate the process of converting raw materials like cement, sand and aggregates into uniform bricks. Machines in this category range from manual to fully automatic systems, addressing needs from small-scale to industrial manufacturing.

Manual models like the LT2-40 brick making machine depend on human operation. These machines suit limited production settings and require minimal technical skill. Typical outputs remain below 1,000 bricks per day, making manual options practical for small or emerging businesses.

Semi-automatic machines, such as the QT4-25C, include hydraulic systems and partial automation. Operators control block proportions and automate moulding functions while hydraulic mechanisms improve block density and finish. These machines produce hollow, solid and paver blocks for projects demanding moderate capacity.

Fully automatic systems, such as the QT4-15 and LT4-10, use PLC control panels to manage the entire production cycle. These machines mix, compress and mould blocks with minimal human interaction. High-capacity automatic lines deliver up to 4,000 bricks per eight-hour shift, supporting large-scale construction or consistent demand for cost-effective building materials.

AAC block plants, such as the Autoclaved Aerated Concrete systems, use a specialised process to create lightweight blocks with superior insulation properties. Automated AAC lines control mixing, moulding and autoclaving steps for consistent thermal and structural characteristics, ideal for energy-efficient projects.

Efficient operation, precision in block size and material mix, and scalable production define cement brick making machines. Selection depends on project size, required block types, labour availability and automation preferences.
