Skip Hoist Type Concrete Batching Plant
2025.07.09
Skip hoist type concrete batching plant is a concrete production equipment that uses bucket lifting as the main feeding method. It is suitable for small and medium-sized engineering scenes and has the characteristics of compact structure, small footprint and flexible mobility.
The theoretical productivity of skip hoist type concrete batching plant is usually 25-75m³/h (such as the actual output of HZS35 concrete batching plant is about 30m³/h, HZS75 concrete batching plant is about 50m³/h), suitable for small and medium-sized projects such as rural infrastructure, bridge prefabrication, small commercial concrete mixing station, etc. Its modular design facilitates quick installation and low relocation cost, especially suitable for temporary projects.
Core structure of skip hoist type concrete batching plant:
- Feeding system
Adopting climbing bucket lifting structure (such as Fangyuan Group HZS75 model), the bucket is driven by electric or hydraulic drive to lift the sand and gravel aggregate to the waiting hopper above the mixing main machine. Compared with belt conveyor, bucket feeding does not require long-distance belt, reduces the floor space by 50%-60%, and the fully enclosed design effectively reduces dust spillage.
- Mixing main machine
Twin-shaft forced concrete mixers (such as JS series) are commonly used. The gap between the mixing blades and the inner wall of the mixing drum is small. It can efficiently mix dry hard, semi-dry hard and fluid concrete, with high mixing uniformity and wear resistance. Some models are equipped with anti-stick shaft design to reduce the workload of cleaning.
- Measuring and control system
Aggregates, cement, water and admixtures are measured by independent electronic scales with an accuracy of ±1%-±2%. The control system mostly adopts PLC + industrial computer mode, supports formula storage, data traceability and fault diagnosis, and some high-end models integrate IoT modules to remotely monitor production status.
- Environmental protection configuration
Dust treatment: A pulse dust collector is installed on the top of the powder silo, the mixing building is fully enclosed and equipped with a secondary dust removal device, the aggregate conveying is fully enclosed and a vibration arch breaking system is installed to reduce dust emission.
Wastewater recovery: equipped with a sand and gravel separator and a filter press, the wastewater from cleaning the tank truck and mixer is recycled after treatment, and the precipitated waste residue can be reused in concrete production.
Noise control: The main machine is encapsulated with a soundproof board, the air circuit system uses a buffer cylinder, and noise-reducing green plants are planted around the factory area to effectively reduce operating noise.
Workflow of skip hopper concrete batching plant:
- Aggregates (sand and gravel) are weighed on the ground and loaded into the skip;
- The skip rises along the guide rail to the top of the mixing main machine;
- The skip flips and pours the aggregates into the mixing main machine;
- At the same time, powder, water and admixtures are also added in proportion;
- After mixing, the concrete is discharged from the bottom discharge port.
Skip hoist type concrete batching plants have many advantages that make them widely used in concrete production.
1. Efficient material transportation
Skip hoist type concrete batching plants are equipped with bucket elevators, which can quickly transport various raw materials (such as cement, sand, stone, etc.) from the silo to the mixer. This design greatly improves production efficiency and reduces material handling time.
2. Accurate batching
Skip hoist type concrete batching plants are usually equipped with advanced weighing systems that can accurately control the proportions of each component to ensure that the quality and performance of the concrete meet standard requirements. This is especially important for the production of high-strength concrete and special concrete.
3. Excellent mixing effect
The use of powerful mixing equipment such as twin-shaft concrete mixers can ensure that the various components of concrete are fully mixed, improve the uniformity and stability of concrete, and thus improve the quality of building structures.
4. Automated control
Modern skip hoist type concrete batching plants are usually equipped with computer control systems that can achieve fully automated operation. This not only improves production efficiency, but also reduces manual intervention and reduces the possibility of human error.
5. Small footprint
Compared with traditional concrete mixing plants, skip hoist type concrete batching plants have a relatively small footprint and are suitable for use on construction sites with limited space.
6. High flexibility
Skip hoist type concrete batching plants can flexibly configure different numbers of silos and mixers according to needs to meet the needs of concrete production of different scales and types.
7. Convenient maintenance
The structure of the skip hoist type concrete batching plant is relatively simple, easy to maintain and maintain, which can effectively extend the service life of the equipment and reduce operating costs.
8. Strong adaptability
It can adapt to various types of concrete production needs, including ordinary concrete, ready-mixed concrete, special concrete, etc., to meet the requirements of different engineering projects.
9. Environmental performance
Modern skip hoist type concrete batching plants are designed with environmental protection factors in mind and are equipped with exhaust gas treatment and noise control devices to reduce the impact on the environment.
Skip hoist type concrete batching plants have become an important equipment for modern concrete production due to their high efficiency, precise batching, excellent mixing effect and automatic control, and are suitable for various construction projects and infrastructure projects.
