What is JZC350 concrete mixer?
JZC350 drum concrete mixer is a medium-to-small-sized concrete mixing equipment that operates on the self-falling mixing principle. It is suitable for mixing various types of plastic and semi-dry hard concrete. With a compact structure, easy operation, and convenient mobility, it is widely used on construction sites, road and bridge projects, and precast component factories. It is especially ideal for rural or temporary construction sites.
How does JZC350 concrete mixer work?
JZC350 features a structure that mixes when rotating forward and discharges when rotating in reverse:
During mixing: The motor rotates forward, driving the mixing drum to rotate in the same direction via gears. Inside the drum, the materials are lifted by the blades and fall freely, achieving thorough mixing.
During discharging: The motor rotates in reverse, causing the drum to rotate in the opposite direction, and the mixed concrete is automatically poured out through the discharge outlet.
Parts of JZC350 Concrete Mixer
1. Mixing Drum: A double-cone structure with built-in mixing blades, which rotates to mix and discharge the concrete.
2. Driving System: Composed of a motor, reducer, and gears, it drives the rotation of the mixing drum.
3. Feeding System: Equipped with a hopper, which lifts materials using a hoisting mechanism.
4. Discharging Mechanism: Utilizes reverse gear control to rotate the drum in the opposite direction for automatic discharging.
5. Wheels and Support Frame: Allows for short-distance movement, making it convenient to relocate on construction sites.
6. Electric Control System: Manages operations such as mixing, feeding, and discharging, with a simple and intuitive control panel.
Advantages & Features
1. Compact Structure: Small footprint, ideal for construction sites with limited space.
2. Easy Operation: High degree of automation; can be operated by a single person.
3. Uniform Mixing: Blades inside the drum are reasonably arranged, ensuring high mixing quality.
4. Energy Efficient and Durable: Moderate motor power, low operating cost, and long service life.
5. Convenient Maintenance: Few wearing parts, easy to repair, and spare parts are readily available.

Operation and Maintenance Guidelines
Before operation, check the electrical system, lubrication system, and ensure the drum rotates properly.
Follow the specified mix ratio during operation; overloading is strictly prohibited.
Clean out residual materials from the drum after each use to prevent hardening.
Regularly inspect bearings, chains, gears, and other components for wear, and replace or lubricate as needed.
The electrical control box should be protected from rain and dust, and ensure proper grounding.

FAQ
1. What is the rated capacity of the JZC350 concrete mixer?
The JZC350 is a self-falling drum concrete mixer with a rated discharge capacity of 350 liters, capable of mixing approximately 0.35m³ of concrete per batch. Its feeding capacity is 560 liters, making it ideal for small projects or rural house construction.
2. Does this mixer require an external power supply? What is the power consumption?
The JZC350 typically uses three-phase 380V AC power, with a motor power of about 5.5 kW. If three-phase electricity is unavailable on site, a diesel engine-driven model is also available (subject to manufacturer configuration).
3. What is the drum rotation speed? How is the mixing performance?
The drum rotates at 14–16 RPM, using the self-falling mixing principle (materials fall freely to mix). It is suitable for standard concrete and mortar, though the efficiency is slightly lower than that of a forced-type mixer.
4. What is the weight of the machine? Is it easy to move?
The total machine weight is about 1800–2000 kg. It is equipped with a tire-mounted tow frame and can be moved using a tractor or manual towing, making it suitable for job sites that require frequent relocation.
5. What should be noted for daily maintenance?
Clean the drum after each use to prevent concrete hardening.
Regularly check the oil level in the gearbox and lubricate the bearings.
When not in use for a long time, disconnect the power and cover the machine to prevent rain and rust.
6. What is the difference between JZC350 and JZC500?
The JZC500 has a larger capacity (0.5 m³ per batch) and higher motor power (about 7.5 kW), making it more suitable for medium-scale projects. However, it is also larger in size and higher in price.
