JZM750 Drum Concrete Mixer
JZM750 drum concrete mixer is a double-cone reverse discharging concrete mixer, which belongs to the self-falling friction drum mixing equipment and is suitable for mixing plastic and semi-dry hard concrete. This model is widely used in construction sites, roads and bridges, hydropower projects and small and medium-sized concrete component plants. It is favored by the market for its stable mixing quality, low noise and high production efficiency.
Capacity：30-35m³/h
Warranty: 18 months
Mixer Motor Power: 2×7.5Kw
Voltage: 220v/380v/415v/440v/480v(50Hz/60Hz)
Product Structure
The JZM750 mixer is mainly composed of the following core components:
Mixing system
Mixing drum: adopts double cone design, forward mixing, reverse discharging, and spiral blades inside to ensure uniform mixing of concrete.
Transmission mode
Rubber roller friction transmission (mainstream design): 4 rubber rollers drive, lower noise (reduced by more than 30%) and smoother operation compared to gear transmission.
Gear transmission (some models): more reliable transmission, no slipping in rainy and foggy days, but higher noise.
Power system
Mixing motor (2×7.5kW): drives the mixing drum to rotate.
Lifting motor (7.5kW): used for climbing bucket loading (some models support hydraulic lifting).
Water pump motor (1.1kW): controls the water supply system to ensure accurate ratio.
Traveling mechanism
Tire specifications: 750-16, supports towing movement, maximum speed 20km/h (some large models are designed to be fixed).
Outrigger stabilization system: the level can be adjusted during operation to enhance stability.
Water supply system
Adopts automatic metering water supply with an error of ≤2% to ensure accurate concrete mix ratio.
Working principle
The JZM750 drum concrete mixer adopts a working mode of forward mixing and reverse discharging.
Feeding stage:
Material (cement, sand, gravel, water) is put into the mixing drum through a crawler bucket or hydraulic lifting.
Mixing stage:
The mixing drum rotates forward, and the internal blades lift the concrete and let it fall freely, forming a self-falling mixing to ensure uniform mixing.
Discharging stage:
After the mixing is completed, the mixing drum reverses and the concrete is discharged along the spiral blades.
Product Advantages
Low noise, high stability
The rubber wheel friction transmission is used, which reduces the noise by more than 30% compared with the gear transmission, and is suitable for construction in urban residential areas.
High mixing quality
The double-conical mixing drum + spiral blade design ensures the uniformity of concrete, and is suitable for plastic and semi-dry hard concrete.
High production efficiency
The productivity reaches 22.5-35m³/h, which is more than 50% higher than that of small mixers.
Easy to move (some models)
Equipped with traction tires, it can quickly transfer the construction site, suitable for small and medium-sized projects.
Strong scalability
It can be combined with the PLD1600 series batching machine to form a simple mixing station to improve the level of automation.
