Twin Shaft Mixer Design

June 3, 2024

The ingenious twin shaft mixer design makes its mixing effect very good, especially for the viscous and stretchy materials, the mixing effect is more obvious.

Structure composition of twin shaft mixer:

Twin shaft concrete mixer is mainly composed of base frame, mixing tank, two mixing shafts, mixing blades, front and rear supporting body, gears, couplings, reducer, clutch, drive belt, motor, water pipe and cover and other components. The mixing parts are two synchronized spiral rotors with symmetrical shapes, and the two spiral shafts are synchronized in speed and opposite in direction during rotation.

Mechanical part design of twin shaft mixer:

Transmission system: including electric motor, reducer, gears and bearings, etc. It is used to transmit power and ensure the normal rotation of the mixing cylinder. The selection of motor is based on the production capacity of the concrete mixer and the working environment for comprehensive consideration, while the selection of reducer is based on the reduction ratio and torque size and other factors.

Mixing system: it consists of mixing drum, mixing blades and feeding inlet, etc. The volume of mixing drum is suitable for the production demand, and the number, shape and arrangement of blades ensure that the concrete can be fully mixed.

Hydraulic system: It is mainly used to control the opening and closing of feeding port, discharging port and tilting angle of mixing cylinder, etc. The flow rate and pressure are suitable for the production demand, and the control mode is flexible and convenient.

Design Consideration of twin shaft mixer:

Strength and durability: the design takes into account the strength and durability of the material to ensure that the mixer can run stably for a long time.

Repair and maintenance: the design pays attention to the convenience of repair and maintenance so as to facilitate timely repair in case of failure.

Transportation and installation: the design takes into account factors such as transportation and installation of the mixer to ensure that the mixer can be used normally on site.

Advantages of twin shaft mixer:

Strong mixing capacity: the mixing capacity of twin shaft concrete mixer is strong, and it is effective in mixing dry-hard, semi-dry-hard, plastic and various proportions of concrete.

Short mixing time: the main mixing zone is located in the circumferential direction of the mixer, which can make full use of the mixing space, so that the aggregate, cement and water can reach the average and optimal mixing form in a short time, saving energy.

Environmental protection: the whole mixing and conveying process is carried out in the sealed space, which will not cause dust leakage, clean and environmental protection.

Convenient maintenance: adopting advanced anti-locking shaft system and high-pressure water curtain cleaning system, it is easy to maintain and repair.

Low wear and tear of mixing blades: most of the concrete is piled up between the two mixing shafts during the mixing process, which reduces the wear and tear between the mixing arms, blades and bottom liner.

Low noise: low mixing noise and good working environment.

To summarize, with its unique design and significant advantages, twin shaft mixer occupies an important position in the field of concrete mixing equipment.
