Stationary plants meaning

What is a stationary concrete batching plant? A stationary concrete batching plant is a concrete mixing equipment installed in a fixed position. The foundation of stationary plants is fixed, and usually requires pouring and installation of concrete foundation. It is mainly used for large-scale and long-term concrete production, such as large construction sites, prefabricated component plants, etc., for continuous and large-scale production of concrete.

HZS series concrete batching plant

The size of fixed batching plant is divided by its theoretical production capacity per hour. At present, the common batching plant specifications include HZS25, HZS35, HZS50, HZS60, HZS75, HZS90, HZS120, HZS180, HZS200, HZS240, HZS270, HZS360 and other series.

The letter H in the HZS series stands for concrete, Z stands for batching plant, and S stands for the main engine of the double-horizontal forced batching plant. The numbers express the output per hour. For example, HZS120 refers to a concrete batching plant with a production capacity of 120 cubic meters per hour.

Two types of stationary concrete batch plants

Types	Hopper type stationary concrete batching plant	Belt type stationary concrete batching plant
Introduction	The hopper-type fixed mixing plant is a concrete mixing equipment that transports aggregates by lifting the hopper. It is suitable for compact sites and medium production needs.	Belt-type fixed mixing plant is used to transport aggregates through belt conveyors, which is suitable for large-scale continuous construction projects.
Application scenarios	Mainly used in small construction sites, road maintenance and other projects, suitable for occasions with low production demand.	Suitable for large-scale infrastructure projects, professional concrete production enterprises or projects that require a large amount of concrete for export.
Performance characteristics	Small footprint: Based on the 7.5-meter feed height and 60° bucket design angle, it can save a lot of space compared to the belt equipment system. Enhanced durability and strength: The track wheel is manufactured by forging process, with high strength, strong wear resistance and low maintenance cost. Low investment cost: The equipment structure is relatively simple, the investment cost is low, and it is suitable for small projects with limited budgets. Easy maintenance: The equipment uses less equipment, convenient maintenance, and safe and fast actual operation.	Efficient aggregate transportation: Aggregates are transported by belt conveyors, which have stable operation, high transportation efficiency, and continuous operation to reduce maintenance time and costs. Accurate weighing: The aggregate weighing system ensures accurate batching, and the batching accuracy can reach ±2%, ensuring the quality of concrete production. High production efficiency: It can meet the needs of large-scale continuous construction projects, with high production capacity and excellent concrete quality. Large footprint: Compared with hopper-type mixing plants, belt-type mixing plants have a larger footprint, but can better meet the needs of large-scale production.
Technical parameters	Taking HZS25 concrete mixing station as an example, the theoretical productivity is 25m³/h, the maximum weighing value of aggregate scale is 800kg, the maximum weighing value of cement scale is 300kg, the maximum weighing value of water scale is 150kg, the maximum weighing value of admixture is 40kg, the cement silo capacity is 100 tons, the mixing power is 18.5kW, the lifting power is 5.5kW, the whole machine power is 60kW, the unloading height is 3.8 meters (1.6 meters), the aggregate metering accuracy is ±2%, the water metering accuracy is ±1%, the cement metering accuracy is ±1%, the admixture metering accuracy is ±1%, and the automatic cycle period is 72 seconds.	Taking the AJ-180 belt-type mixing plant as an example, its aggregate conveying capacity can reach 1,000 tons/hour

Composition of stationary concrete batching plant

A complete set of mixing equipment is composed of many main machines and some auxiliary equipment. Its most basic components are the following five: transportation equipment, hopper equipment, weighing equipment, mixing equipment and auxiliary equipment, as shown in the figure below.

Sand weighing Stone weighing Discharging gate Conveyor belt Upper limit of dumper Lower limit of dumper Sand conveyor Stone conveyor Sand box Stone box Mixer Pump motor Cement screw conveyor Additive screw conveyor

(1) Transportation equipment

Transportation equipment includes aggregate transportation equipment, cement conveying equipment and water pumps. Aggregate transportation equipment includes belt conveyors, draglines, grabs and loaders, among which belt conveyors are the most commonly used aggregate transportation equipment in mixing devices. Cement conveying equipment and additive conveying equipment are composed of bucket elevators and screw conveyors.

(2) Hopper equipment

Hopper equipment is composed of storage hoppers, unloading equipment (valves, feeders, etc.) and some other auxiliary devices. Hopper equipment plays the role of an intermediate warehouse in production to balance production. In concrete mixing devices, hopper equipment is used in conjunction with automatic scales for batching. Therefore, it is a component of process equipment and is not a storage place for bulk materials.

Feeders and gates are both unloading equipment for storage hoppers. Gates control the opening and closing of the storage hopper discharge port. Most of them are pneumatic. They have a simple structure and a large unloading capacity. However, they can only control the material flow more evenly when the material is in a completely loose state. It is easier to control the uniform discharge of materials by feeders, and feeders are all electric. There are many types of gates, but the most common type in concrete mixing plants is the fan gate, which is operated by a compressed air cylinder. Aggregates (stone and sand) are fed by gates.

(3) Weighing equipment

Weighing and batching equipment is an important process equipment in the concrete production process. It controls the proportion of various mixtures. The accuracy of weighing and batching has a great influence on the strength of concrete. Therefore, accurate and efficient weighing equipment can not only improve productivity, but also is a reliable guarantee for the production of high-quality and high-strength concrete. A complete set of weighing equipment includes storage hoppers, feeding equipment (gates and feeders) and weighing equipment. The requirements for weighing equipment are first accuracy and second speed.

(4) Mixing equipment

Mixing equipment is a general concrete mixer without a hoist device and a water supply device. Its design technology is mature. In the design of mixing stations, standard mixers are generally used. For example, currently domestic manufacturers basically use twin-shaft forced mixers, which have strong mixing capabilities, uniform and rapid mixing, and high productivity. They can achieve good mixing effects for dry hard, plastic, and various proportions of concrete.

Which is better, stationary or foundation-free?

For the concrete mixing industry, both fixed batching plants and foundation-free batching plants are common choices, but there are some key differences between them. This article will compare and analyze the differences between these two types of concrete batching plant equipment from the following three aspects.

1. Different scope of application:

Foundation-free concrete batching plants are suitable for small-scale or frequently moved concrete production tasks, while fixed concrete batching plants are suitable for large-scale, continuous concrete production tasks.

2. Different installation methods:

Foundation-free concrete batching plants are a type of mobile concrete batching plant that does not require a special foundation. It consists of aggregate silos, metering systems, mixers, conveying systems, and electrical control systems, and can be quickly moved to different construction sites. Fixed batching plants require a concrete foundation to be built on the ground to ensure their stability and durability. Installation takes longer and costs more, but can handle larger concrete outputs.

3. Different equipment composition:

Foundation-free batching plants usually include a mobile frame, a concrete mixer, and a hopper for storing raw materials. They can be easily moved to the site where concrete is needed and produce concrete by mixing cement, sand, and aggregates. A stationary concrete mixing plant usually consists of one or more concrete mixers, a hopper for storing raw materials, a conveyor belt and a concrete discharge hopper.
