Structure
The JS750 twin-shaft forced concrete mixer consists of several key components that work together to ensure efficient and stable operation.
At the core, the mixing drum adopts a twin-shaft structure and contains multiple mixing blades. These blades actively force the concrete materials to mix thoroughly, ensuring uniform consistency.
Within the drum, the twin-shaft mixing system uses two horizontally arranged rotating shafts. Through strong rotational force and symmetrical mixing action, the system delivers fast and even material blending.
To provide sufficient power, a high-performance motor drives the mixer and maintains stable operation even under heavy load conditions.
Meanwhile, the reducer and transmission system efficiently transfer power from the motor to the mixing shafts, ensuring smooth rotation and reliable torque output.
For material input, the feeding system incorporates practical structures such as a feeding hopper or lifting device. This design allows operators to load cement, sand, gravel, and other raw materials quickly and efficiently.
Once mixing is complete, the discharging system releases the finished concrete rapidly through the discharge port, improving overall work efficiency.
In terms of operation, the mixer integrates an intelligent control system that supports both manual and automatic control modes, offering flexibility for different working conditions.
Finally, the frame and support structure use high-strength steel to ensure overall stability and durability. Depending on site requirements, the mixer features support legs or a wheeled chassis for easy installation and relocation.
Working principle
The JS750 twin-shaft concrete mixer operates according to a clear and efficient working principle.
At the input stage, operators load cement, sand, gravel, and other concrete raw materials into the mixer through the feed port. An automatic lifting device typically transfers the materials from ground level into the mixing drum, improving feeding efficiency.
During operation, the motor starts and drives the reducer, which then transmits power to the twin mixing shafts. As the shafts rotate, the mixing blades spin at high speed. Under the action of the forced mixing system, the materials continuously flip, collide, and interlock inside the drum, ensuring thorough and uniform mixing.
Once mixing is complete, the operator controls the discharge system to open the discharge port. The mixer then releases the finished concrete quickly for downstream use. Overall, the entire process runs smoothly and efficiently, maximizing productivity while saving time.
