An automatic fly ash brick making machine is used to manufacture superior quality fly ash bricks by utilizing high pressure. The machine has a production capacity range of 1,000 to 2,500 bricks per hour. It uses these raw materials to produce fly ash bricks; fly ash at 50 -55 %, sand dust at 25-30%, gypsum and lime at 15-20% or cement at 7%.
Generally, fly ash bricks are manufactured by compressing the different materials into the mould. Consequently, these materials are hydraulically pressed. The hydraulic section is central to the operation of the automatic fly ash brick maker.
Components of an automatic fly ash brick making machine
1. The Pan Mixer: This is the compartment where the raw materials such as water, cement, fly ash and sand are mixed in the right proportions. The mixer has a motor and mixing arms to ensure a homogeneous mix.
2. Mixed Material Belt Conveyor: After the materials are fully combined in the pan mixer they are passed from the pan mixer through the discharge gate to the hydraulic brick press using the belt conveyor. The conveyor belt is kept in motion by moving parts such as driving rollers, driven roller and idlers rollers.
3. Hydraulic Bricks Press: This is the section in which the actual brick making occurs. Normally, the hydraulic interlocking brick making machine press is assembled using a strong plate with the requisite thickness so that it can bear the enormous pressure applied to the bricks. 6 to 8 MT of pressure is applied to every single brick to strengthen it. The brick press system is plc controlled. Also, there is a feeder fan that is used to make sure that materials are quickly filled in the mould cavity.
4. Hydraulic Power Pack: The component consists of other parts that are essential in exerting hydraulic pressure on the bricks. Some of the parts include; direction valves, hydraulic pump, oil level indicator, pressure gauge and pressure control valves. This component is integral in supplying hydraulic oil in the necessary pressure and quantity to support raw material pressing.
5. Control Panel: The entire system is controlled using a Programmable Logic Controller (PLC). This control module can be accessed from the control panel of the automatic fly ash brick making machine.
Features of bricks produced
The bricks produced by automatic fly ash brick maker usually weigh around 2.75 – 3.25 kg per brick depending on the amount and quality of sand used. Also, their water absorption rate is approximately 12-16%. Fly ash bricks are extremely durable due to their production process. They can be used in infrastructure projects such as the construction of irrigation works, pavements, dams, canal lining and tanks.
In conclusion, an automatic fly ash brick making machine is used to produce properly engineered bricks that can be employed in a wide range of applications. Its design is usually reliable and sturdy to ensure that it can be used to produce fly ash bricks for several years without breaking down. This machine is a worthy investment that you will not regret.
