50m3/h Small Concrete Batching Plant

The 50m3/h small concrete batching plant (typically model HZS50) is an efficient and flexible concrete production equipment suitable for small and medium-sized construction projects, precast component plants and rural infrastructure development.

1. Core Technical Parameters

The theoretical production capacity is 50 cubic meters per hour. In practice, this capacity typically reaches 40-45 cubic meters per hour, depending on factors such as raw material supply and equipment maintenance. The cycle time is approximately 72 seconds per cycle, with a discharge capacity of 1 cubic meter per cycle.

– Main Unit Configuration

Main Unit: JS1000 twin-shaft forced concrete mixer with a discharge capacity of 1 cubic meter and a mixing power of 37 kW. It can mix aggregates up to 80 mm in size and is suitable for a variety of concrete types (such as plastic and semi-hard concrete).

Batching Machine: Standard configuration includes a PLD1600 four-bin accumulating batching machine with a total hopper capacity of 13 cubic meters. The aggregate weighing range is 3,000 kg (with an accuracy of ±2%), the cement weighing range is 600 kg (with an accuracy of ±1%), and the water and admixture weighing accuracy is ±1%.

– Power and Energy Consumption

Total power: Approximately 85-127 kW (depending on configuration, such as the inclusion of additional equipment such as an air compressor and conveyor belts).

Power Requirements: Three-phase 380 V/50 Hz. A separate transformer or generator is required. A 15% overload capacity is recommended.

– Footprint

The machine body: For an L-shaped layout, the footprint is approximately 20 m × 15 m (300 m²); for a straight-line layout, the footprint is approximately 30 m × 7 m (210 m²).

Overall Site: If including a gravel storage yard, office area, sedimentation tank, etc., an area of approximately 2,000-3,300 square meters is required.

2. Key Systems and Configurations

– Material Conveying System

Aggregate Hoisting: Utilizes a bucket elevator or belt conveyor with a hoisting speed of 0.8 m/s and a hopper capacity of 1.5 cubic meters. It is equipped with limit switches for overwind protection and drop protection.

Powder Supply: Standardly equipped with one or two 100-ton cement silos (3 m diameter, 12 m height), equipped with built-in air-blast arch-breaking devices and radio frequency level switches, the powder is conveyed to the weighing hopper via an LSY250 screw conveyor (30 m³/h capacity).

– Metering and Control System

Metering System: Aggregates are dynamically metered using a belt scale, while cement, fly ash, water, and admixtures are statically metered using independent weighing hoppers. Accuracy meets national standards (aggregate ±2%, powder ±1%, water ±1%).

Control System: The mainstream configuration is a PLC + touch screen, supporting both automatic and manual modes, capable of storing 100 recipes, and equipped with features such as head compensation, out-of-tolerance alarms, and production data statistics. Some high-end models support remote monitoring.

– Environmentally Friendly and Safety Design

Dust Control: A pulse dust collector (with a 2000 m³/h air volume) is standard on the cement silo roof, and a dust hood is installed at the mixer discharge port to reduce dust emissions.

Wastewater Recovery: Equipped with a three-stage sedimentation tank (total volume 50 m³) and a filter press, the wastewater reuse rate is ≥80%, meeting environmental requirements.

Noise Reduction Measures: The mixer and conveyor are equipped with soundproof enclosures, with noise emissions ≤70 dB (daytime) and ≤55 dB (nighttime).

3. Performance Advantages

– Efficient and Stable:

The forced concrete mixer achieves a mixing uniformity error of ≤5%, ensuring that concrete strength meets standards.

– Easy Operation:

The high degree of automation allows single-person operation, reducing labor costs.

– Highly cost-effective:

The investment cost of HZS50 concrete batching plant is approximately 20,000-40,000 dollars(standard domestic equipment), making it more suitable for small and medium-sized projects than large-scale concrete batching plants.

– High Flexibility:

The modular design facilitates disassembly and relocation, making it suitable for field construction or temporary projects.

4. Typical Applications

– Construction: Rural self-built houses, township roads, small bridges, and water conservancy facilities.

– Precast Parts Production: Mass production of prefabricated components such as concrete blocks, utility poles, and pipe piles.

– Infrastructure: Railway and highway maintenance, rural drinking water projects, and farmland irrigation system construction.

5. Installation and Maintenance

The installation cycle, from site preparation to commissioning and operation, takes approximately 60 days, including foundation construction (15 days), equipment installation (20 days), commissioning and acceptance (10 days), and personnel training (5 days).

Maintenance Key Points

– Daily Maintenance: Regularly inspect the mixer liner and blades for wear (service life ≥ 8,000 hours), clean any residual material from the metering hopper, and ensure sensor accuracy.

– Replacement of Wear Parts: Conveyor belts, screw conveyor blades, discharge door seals, etc. should be replaced promptly based on wear.

– Regular Maintenance: Conduct a comprehensive inspection of the electrical system, pneumatic components, and steel structure every quarter to ensure safe operation of the equipment.

6. Price Reference

The HZS50 concrete batching plant is priced at approximately 20,000-70,000 dollars and comes standard with a JS1000 mixer, PLD1600 batching machine, and a semi-automatic control system. HZS50 with Sicoma mixer typically cost between 50,000 and 100,000 dollars and feature higher-end features (such as a fully stainless steel metering system and European-standard motors), making them suitable for projects with stringent quality requirements.

7. Selection Recommendations

– Clarify Requirements: Choose a fixed or mobile concrete batching plant based on the project scale (e.g., total concrete usage and daily output). Mobile concrete batching plants are more expensive but offer greater mobility.

– Focus on Configuration: If producing high-strength concrete (such as C50), prioritize equipment with high metering accuracy and excellent mixing performance (such as a twin-shaft mixer).

– Investigate the Manufacturer: Prioritize ISO-certified manufacturers with comprehensive after-sales service. Visit their production facilities and on-site installations.

– Environmental Compliance: Ensure the equipment is equipped with environmental protection facilities such as dust collectors and sedimentation tanks, complying with local environmental regulations.

The 50m3/h small concrete batching plant, with its high efficiency, cost-effectiveness, and flexibility, is an ideal choice for small and medium-sized construction projects. Its core configuration (such as the JS1000 concrete mixer and PLD1600 batching machine) and intelligent control system can meet most project requirements, while its reasonable price and low maintenance costs further enhance its market competitiveness. When selecting a model, consider the actual project needs and budget, prioritizing brand reputation and environmental performance to ensure long-term stable operation of the equipment.
