Brick making machines are classified to semi-automatic and manual machines as follows:
Manual brick making machine
Manual brick making machines are cheap and best if only a small quantity of bricks is required. Because it is manual, the mixing, filling, and pressing activities are done physically. Hand-operated machines have small production capacities ranging from 500 to 1000 bricks daily. The low output has also been compensated by their low space requirements. These machines are portable and appropriate for small-scale constructions, do-it-yourself projects, or remote areas lacking electrical power. Moreover, as a consequence of their simple design, they are relatively easy to maintain. As such, if low-cost, low-output structures are needed, a manual brick making machine is the best option.
Automatic brick making machine
Automatic brick machines generally yield a higher output than manual machines. While more costly than manual machines and often requiring electrical energy or diesel, the production is more effective because raw bricks accomplish better homogeneity and density. Automatic machines are able to produce between 2000 and 2500 bricks daily with a large capacitance, which is suitable for significant developments such as residential estates or commercial complexes. Though they might require more space for installation, they provide the advantage of reduced labor costs and higher work efficiency. These machines also have the capacity of including extra features, such as automatically curing set and automated material transport mechanisms.
Semi automatic brick making machine
Semi-automatic machines are somewhat a blend of manual and automatic machines. Even though these machines use some power, some parts of the production process are done manually. They are suited for medium brick production requirements, typically ranging from 1000 to 1500 daily. Semi-automatic machines are likely to be relatively cheap and suitable for medium-sized corporations or projects. They could also work well in locations where electrical energy might not be constantly available. The margin pays for lower expenses, unlike in large automatic plants where the expenses are a lot.
Thermal insulating bricks, structural bricks, paving bricks, and entity bricks are made using brick machinery.
Construction industry
Bricks play a fundamental role in the building industry as structural units. They are widely used for general walls, partitions, and roofing. The brick maker machine can produce a variety of bricks with specific required property values and dimensions to meet different building standards. In this regard, bricks have strengths and longevity, making them ideal for supporting structures. In the case of using concrete bricks, these contribute higher strength and help in reducing the overall costs of construction.
Road construction
Paving bricks display immense utility in roads and literal path construction, as they provide a durable and aesthetic hard surface. Also, they are easily replaceable, and any individual brick can be removed without having to displace the entire structure if a single brick is damaged. Paving bricks come in colorful and textured designs that improve the general appearance of roads, driveways, and walkways. Nowadays, eco-friendly permeable paving bricks are manufactured, which aid in stormwater management and reduce runoff.
Fire protection
Industrial applications find use in firebricks, or fireclay bricks, which can withstand higher temperatures. They line furnaces, kilns, and fireplaces since they do not easily melt or deform when exposed to high levels of heat. Chemical industries, metal smelting plants, and glassworks also use these fire-resistant materials for safer and efficient production processes. This is the same case as thermal insulating bricks, mitigating heat losses in industries and reducing energy costs.
Outdoor landscaping
Bricks are used in outdoor landscaping because they are quite versatile and come in different colors and textures. They are constructed into patios, walkways, and garden walls. Since they are durable, outdoor bricks can withstand changing weather conditions. What is more, they allow the implementation of ecological designs that will permit water absorption and drainage. Retaining walls constructed out of brick machinery help in soil erosion control besides providing structural support in inclined areas.
Infrastructure affected by fire
Bricks, as building materials, are essential in the construction of structures that are required to be fire-resistant, such as schools and hospitals. Even though the intended purpose of firebrick is to afford more protection, even common bricks contribute to some extent by limiting the spread of flames and smoke. Brick structures are preferred in crucial public facilities due to their strength and toughness, ensuring long-term safety.
Production capacity
Commonly applied machines are also cement brick machines production to produce about 600-700 units per hour. However, higher-capacity machines can produce more than 4000 bricks hourly. The quantity cap is affected by the sort of machine and the nature of the bricks to be produced, either automatically or manually.
Hydraulic pressure
Cement bricks machines apply a pressure range of 1000 to 5000 psi when molding the mixture to attain average strength. Bricks utilized in structural support usually carry a higher pressure compared to those for facade application. Automatic hydraulic pressure regulation permits optimum bricks compaction.
Motor power
Motor power generally ranges from 5-50kw, particularly for automatic machines. High capacity machines require more power. The machine's efficiency power input ratio should be considered when selecting a machine.
Curing methods
Standard curing implemented in brick making machines include steam or water spray, duration ranging from 24-72 hours. Some machines apply dry curing with less moisture, advanced techniques reducing curing time to about 12 hours. Curing methods determine several bricks produced and quality.
Brick size
Most brick making machines are configured to produce standard bricks 240mm in length, 115mm in width, and 75mm in height. Machines vary as per customer specification to produce custom sizes. Size affects the number of units produced within a given time frame and space.
Material requirements
Brick making machines also have various material requirements, including coarse aggregates, cement, sand, and steel fibers for enhanced strength. Specific materials depend on the type of brick to be produced. Some new machines incorporated additives help in reducing the weight of the material.
Production capacity
Buyers should contemplate the brick machine's production capacity and safety margins. The capacity usually requires being compatible with project size or business objective. Machines producing more than 1000 bricks daily are adequate for big projects. On the other hand, machines producing less than 1000 bricks daily meet small projects. Tasks require more attention and time to complete if the machine selected has a lower capacity than needed. Conversely, larger machines are uneconomical when the production requirement is just low.
Labour requirements
Probably the key consideration is how many workers will be required for the operation. Full automation, requiring no manual assistance, entail such a machine, while semi-automatic ones will need fewer workers to perform tasks like mixing. Manual machines are the most labor-strained to operate. Depending on the level of mechanization of a machine, buyers should balance labor costs against expected productivity.
Maintenance and support
Maintenance is a matter of health too. Machines undergo wear and tear in the course of performing task functions. Find out the manufacturer to provide after-sale service readily as well as being located nearby. Also, determine whether the spare parts supplied in the market are for that machine. Some vendors provide warranty machines for various frames, which may come in handy in emergencies.
Brick variety
Different making machines produce different kinds of bricks. Some machines offer flexibility, that is, allow the production of different bricks, including concrete, fly ash, and interlocking bricks. Others are specialized in a specific type, such as producing hollow bricks only. Buyers should ensure they select making machines that produce required bricks.
Budget considerations
Budget is another consideration when buying a brick-making machine. As a general rule, more so dependent on the making machine type, the machine's price will be high, especially when it comes to automatic machines. Moreover, additional expenses include maintenance, operation, and labor costs. Buyers should weigh different costs against benefits and find the best solution.
Energy efficiency
Energy efficiency increases to give back in energy-saving form hence is worth considering. Many machine types available in the market primarily work with decreased levels of energy, especially when engaging with new inventions as opposed to older ones. Solar technologies and energy-efficient motors are incorporated into some newer machines. Additionally, check how efficient the kiln used for drying is. Drying takes much time and can lead to fuel wastage if the kiln is not efficient.
A1. The machine mixes cement, sand, aggregates, and water into a homogeneous slurry. It fills a mold with the slurry and uses hydraulic pressure to compact it, forming a solid brick. The molds are usually heated or placed in a dry area to promote quick drying.
A2. A brick making machine can be worth it if the scale of production is large enough to offset its cost. Bricks are made quickly up to hundreds in an hour.
A3. The best bricks have a minimum compressive strength of 3.5 N/mm² to 7.5 N/mm². The cement-brick mixture's pressure requires a machine to compact the mixture to this strength.
A4. Standard bricks are rectangular, measuring 230 millimeters in length, 110 millimeters in width, and 76.2 millimeters in height. Other bricks also measure the same but different in length, width, and height.
