What Is a Twin Shaft Concrete Mixer?
A twin shaft concrete mixer is often used for mixing different powder materials and creating different powder mixing materials. Typically, it can mix the dry hard concrete, lightweight concrete, and ordinary concrete. What’s more, it has many applications in other industries.
A twin shaft concrete mixer has many special qualities such as unique structure type, strict quality control, reasonable and scientific design, etc. It also offers many benefits such as easy to pour, high concrete vibrating performance, easy to clean, better discharge performance, more uniform mixture, and high stirring efficiency. It’s, therefore, more suitable for hydropower and water conservancy projects during the RCC pouring process.
Components
The twin shaft concrete mixer consists of a chain cover, piping, drive device, cover, screw shaft assembly, the chassis, and other components. The plate products alongside other parts are assembled to form the chassis shell, which is the key support of the equipment.
The chassis shell is often sealed tight to avoid fly ash leakage. The main component of this twin shaft concrete mixer is the screw shaft assembly. It usually comprises of the right and left rotation screw shaft, blades, oil cups, sprockets, gears, bearing covers, bearing sets, bearing, and other parts. You should opt for a double shaft mixer that has great mixing performance, heavy-duty design, with low noise and shaft end sealing technology, easy to operate, and with less pollution as well.
Like mentioned earlier, this appliance is made up of an electrical control system, limit device, transmission system, mixing device, and the chassis. The chassis has beautiful appearance and supports the entire concrete mixer. The stirring device is made up of a stirring blade, stirring shaft and stirring cylinder. The stirring blade is attached to the stirring arm and is built integrally with the specific stirring shaft; both of the two sets have opposite directions. However, the spiral stirring shovel with a similar angle, the lead, the gap between the mixing cylinder interior arm and the mixing shovel can be slightly adjusted.
The transmission system is made up of the coupling and the deceleration machine. The cylinder limit comprises of the positioning hole and the locking pin, while the electrical control system plays the role of starting, timing, stopping, and jogging.
Twin Shaft Concrete Mixer: Working Principles
After adding the mixing raw materials into the concrete mixer, the stirring shaft rotates with the help of the reducer motor drive in a single direction via the coupling, the negative and positive two sets on the stirring shaft mixing material’s shovel blade.
Due to the impact caused by the spiral angle, the materials are pushed by the shovel from one side to the other, and then back to the first side, so that the materials can be sufficiently stirred to obtain a great mixing effect. The mixer should be stopped when the discharge time comes by hitting the lock, adjusting the cylinder rotation to a specific angle. Pressing the jog button will automatically discharge the mixture from the cylinder.
In addition, you must choose reliable twin shaft concrete mixer machine manufacturers, you can get affordable and quality one.
