Small Concrete Batch Plant For Sale

The HZS small concrete batch plants for sale on the market (typically models such as the HZS25, HZS35 and HZS50) are widely used in small and medium-sized construction projects, prefabricated parts plants, and rural infrastructure projects due to their high efficiency, flexibility and cost-effectiveness.

Small concrete batching plants has many advantages, which make them popular in the construction machinery market.

1. Modular Design and Convenient Site Relocation

- Quick Assembly and Disassembly with Low Foundation Costs

The equipment features a modular structure, allowing each component (such as the mixer, batching machine, and cement silo) to be disassembled and transported independently. Installation is achieved through bolts or quick connectors, eliminating the need for complex welding. For example, the HZS25 and HZS35 concrete batching plant weigh approximately 17-21 tons (excluding the powder silo) and can be installed and put into operation in 5-7 days. Foundation construction is simplified, and some models even require no deep excavation, significantly reducing site relocation costs and lead times.

- Compact Layout and Space Advantages

Small concrete batch plants typically utilize a bucket loading system. The highly integrated equipment requires only 50-100 square meters of floor space, making them suitable for urban and rural construction sites with limited space. For example, the HZS35's aggregate silo features a three-bin design, arranged perpendicularly to the main mixer, ensuring efficient space utilization.

2. Efficient Mixing and Precise Batching

- Forced Mixing Technology

The main mixer typically uses a twin-shaft forced concrete mixer (such as the JS500 and JS750). The bidirectional rotation of the spiral blades achieves high-intensity shear mixing of the materials, resulting in a short mixing time (approximately 60 seconds per batch) and excellent homogeneity. It can produce dry hard concrete, lightweight aggregate concrete, and mortar. The concrete mixer's lining is made of wear-resistant alloy material, with a service life of over 20,000 hours.

- Electronic Weighing and Intelligent Compensation

The batching system is equipped with high-precision sensors, achieving a metering accuracy of ±1% for cement, water, and admixtures, and ±2% for aggregates. Some models support automatic head compensation and dynamic adjustments, such as slowing down the aggregate during discharge to prevent overfill, ensuring minimal error in the mix ratio for each batch of concrete.

- Continuous Production Capability

The control system supports "production while scheduling the next batch." Through buffering hoppers and intelligent scheduling, continuous operation is achieved, achieving actual productivity exceeding 90% of the theoretical value.

3. Automated Control and Operational Convenience

- Full-Process Intelligent Control

Utilizing PLC or industrial computer control, the system supports manual, semi-automatic, and fully automatic modes. For example, the HZS25's control panel buttons are labeled in Chinese according to the production process, allowing operators to learn the process in just one to two days. The system can store multiple mix ratios, allowing for single-click access and real-time adjustment of parameters such as water-cement ratio and volume.

- Remote Monitoring and Data Management

Some high-end models (such as the upgraded HZS35 concrete batching plant) support internet access, allowing remote viewing of production data (such as output, energy consumption, and fault alarms) via a mobile app or computer, as well as parameter modification and equipment diagnostics.

- Safety Protection and Fault Diagnosis

The system features self-locking interlocks (e.g., preventing unloading when the mixer is not started), overload protection, and audible and visual fault alarms. The user interface displays real-time equipment status, facilitating quick troubleshooting.

4. Environmental Protection, Energy Saving, and Recycling

- Dust and Noise Control

Fully Enclosed Structure: The main mixer, batching machine, and powder silo are enclosed. Select models are equipped with a negative pressure dust removal system, ensuring dust emissions below 10mg/m³.

Noise Reduction Measures: The mixer is lined with shock-absorbing material, and high-noise equipment (such as the air compressor) is sunken and equipped with a soundproof enclosure. This keeps noise levels within the plant boundary below 55 decibels.

- Wastewater and Waste Recycling

A tertiary sedimentation tank purifies wastewater from mixer cleaning and transport vehicles and reuses it in production. The precipitated sand and gravel waste can be processed into building block raw materials, achieving zero emissions. For example, the HZS25 concrete batching plant has a sedimentation tank volume of 10 cubic meters and a daily wastewater treatment capacity of over 50 tons.

- Energy-Efficient Design

The use of a variable-frequency motor and energy-saving screw conveyor reduces energy consumption by 15%-20% compared to traditional equipment. For example, the HZS35 concrete batching plant has a total power of approximately 50 kW (excluding the screw conveyor), and its average daily power consumption is over 30 kilowatt-hours less than that of older equipment with the same output.

5. Cost-Effectiveness and Flexible Configuration

- Affordability and Return on Investment

The equipment cost of a small plant is approximately one-third to one-half of that of a medium- or large-sized plant, and maintenance is simplified (replacing wearing parts such as mixing blades and liners is inexpensive), making it suitable for small and medium-sized projects with limited budgets. For example, with a daily output of 200 cubic meters, the HZS25 concrete batching plant achieves a payback period of less than six months.

- Customization and Scalability

Optional configurations are available based on your needs:

Loading Method: Elevator (low cost) or Belt Conveyor (high efficiency, suitable for HZS50 concrete batching plant and above).

Powder Silo Capacity: Standard 50-100 tons, expandable up to 200 tons to meet continuous production needs.

Admixture System: Supports precise metering of liquid or solid admixtures, meeting the requirements of high-strength concrete construction.

6. Wide Applicability and Adaptability

- Multi-Type Concrete Production

From ordinary C10-C60 concrete to special concretes such as self-compacting and freeze-thaw-resistant concrete, it can be adapted to meet diverse needs, including rural housing construction, road repairs, and small bridges.

- Adaptability to Complex Working Conditions

The equipment can operate stably in temperatures ranging from -10°C to 40°C. Some models, such as the HZS35 concrete batching plant, have optimized hydraulic systems and electrical components to withstand harsh conditions such as high altitude and humidity.

The HZS small concrete batch plant for sale, with its modular design, high precision, environmental protection, energy saving, and high cost-effectiveness, is an ideal choice for small and medium-sized projects. Designed for both efficiency and flexibility, it meets both standardized production needs and can be customized to accommodate specialized operating conditions. It is a key piece of equipment for improving construction quality and reducing costs in urban and rural construction.
