What is a Skip Hoist Type Concrete Batching Plant?

A skip hoist type concrete batching plant is characterized by the use of a skip hoisting hopper to feed aggregates and sand into the electrical cement mixer. This unique feature is the reason behind its name. It is one of the most popular types of concrete plants available for sale on the market, favored for its efficiency and compact design.

Features of Skip Hoist Type Concrete Batching Plant

1. Compact Design and High Efficiency:  

The skip hoist type concrete batching plant features a modular structure, allowing it to occupy a small area and be flexibly placed according to site conditions. It can discharge ready-mix concrete in multiple directions. Despite its compact size, its optimized design ensures efficiency comparable to belt conveyor type plants.

2. Smooth Hoisting Mechanism:  

The hoisting mechanism operates smoothly with a low failure rate. It uses dynamic drop point feeding to avoid eccentric loads and ensure stable lifting. Additionally, it includes rope loosening protection to prevent reverse rotation.

3. Accurate Weighing System:  

The cement weighing hopper has an octagonal design for improved rigidity and smooth discharge. It features an independent free scale frame and pneumatic self-balancing technology, which prevents issues like supporting scales and pulling scales.

4. Integrated Layout and Quick Installation:  

The plant's main components come integrated with water and pneumatic circuits. Most components are pre-installed at the factory, and with reserved interfaces, installation can be completed within three days at the construction site.

5. Reliable and Durable Wearing Parts:  

The plant uses quenched and tempered H-shaped steel rails, which are resistant to deformation. The skip hoist hopper is protected by intelligent devices such as sensors and travel switches, ensuring safety and reliability. Wearing parts have a service life extending to over 50,000 cubic meters without falling into the bucket.

6. Easy Maintenance and Operation:  

Intelligent design features include automatic lubrication, automatic alarms, and the use of reliable electrical components to simplify maintenance. The system also supports automatic batching, operation, and real-time data monitoring.

7. Powerful Weighing Instrument:  

The weighing instrument includes features such as power-off memory, automatic zero point range tracking, automatic tare weight removal, and advance amount correction, ensuring accurate measurement.

How Does a Concrete Batch Plant Work?

A concrete batch plant operates with precision to ensure the accurate mixing of concrete. The process begins with a wheel loader feeding various storage hoppers containing different sizes of aggregates and sand. These materials are weighed using load cells to ensure precise quantities.

Once weighed, the aggregates and sand are transported to the skip hoisting feeding hopper, which moves them to the concrete mixer's feed opening. Cement is transferred from a metal silo via a screw conveyor, while water is supplied by a water pump and also weighed by separate load cells.

All materials—aggregates, sand, cement, and water—are then fed into the concrete mixer for thorough mixing. After mixing, the concrete can be discharged into a concrete mixer truck or directly into a concrete pump for delivery.

The entire process, including weighing, mixing, and discharging, is controlled automatically by computer software. The concrete formula is inputted into the system, ensuring that all materials are combined precisely to produce high-quality central mix concrete.

Why Choose a Skip Hoist Type Batching Plant?

When selecting a concrete batching plant, the choice between a skip hoist type and a belt conveyor type depends on your specific needs. Here are some reasons why the skip hoist type might be the right choice:

1. Compact Design: The skip hoist batching plant features a compact design, making it suitable for sites with limited space. If your working area is small, this type of plant is an excellent option.

2. Cost-Effective Investment: Compared to the belt conveyor type, the skip hoist batching plant is more affordable. It requires fewer containers for shipping, which can reduce sea freight costs.

3. Ease of Assembly and Mobility: The skip hoist type batching plant is quicker to assemble and easier to relocate between different job sites.
