Stationary concrete batching plant is a complete set of concrete mixing machine, which consists of material storage system, material conveying system, material weighing system, concrete mixing system, electric control system, pneumatic system etc. Different from mobile concrete batching plant, it is fixed on the construction sites, which can’t move easily and casually. Therefore, it is widely used in many construction fields, especially large and small-medium construction projects, roads, railroads, bridges, tunnels, highways, harbors, water conservancy etc. The important thing is that our stationary concrete plant has a wider range of capacity, from 25 m3/h to 240 m3/h. This type of concrete plants are usually called AJ- series concrete batching plant on the market. Clearly, in order to satisfy different construction requirements, Aimix Group produces AJ- series plants, including AJ-25, AJ-35, AJ-50, AJ-60, AJ-75, AJ-90, AJ-120, AJ-180 and AJ- 240.
All of above plants made by Aimix stationary concrete batch plant manufacturer has adopted imported components, which can prolong its service life. The products have been sold to many countries with famous reputation, such as Pakistan, Indonesia, Algeria, Philippines, Australia, Malaysia, Russia, Uzbekistan…….
Main Systems of Stationary Plants
The cement silo is used to store cement and flying ash, which is supported by four legs. The whole silo adopts anti-weary steel materials. It has welded type and Bolt type. The most important thing is that our cement silo is designed reasonably in accordance with the social environment development requirements. On the upper of cement silo is dust collecting device. It can prevent the cement from leaking, which benefits the environment protection.
Besides, the cement silo has arch broken device to avoid cement bond, which can greatly improve materials delivery speed.
2)Concrete batching machine
Our stationary concrete batching machine use PLD series concrete batcher, which consists of feeding system, weighing system and electrical control system. It is used to store and weigh aggregate. The machine can batch aggregate automatically. All weighing processes can be monitored through electrical control system, which can improve working efficiency. It adopts advanced famous brands with high reliability.
According to various materials, there are different conveying methods for various materials.
A. Hopper and belt for aggregate conveying.
For aggregate conveying, in order to meet different needs of users, our stationary concrete batching plants have two kinds of aggregate conveying methods. They are belt type and hopper type.
1)Hopper type: Our plants of AJ-25, AJ-35, AJ-50 and AJ-75 usually adopt hopper feeding method. The hopper type plant is occupied a small area. It has simple structure and low investment.
2)Belt type: AJ-60, AJ-90, AJ-120, AJ-180 and AJ-240 adopt belt conveying way. This conveying method can convey materials with remote distance, high conveying speed, short production cycle, which can improve production efficiency.
B. Screw conveyor for powder material transporting
The screw conveyor is used to convey cement and fly ash from the cement silo to the weighing hopper. It is very suitable for conveying powdery materials. The screw conveyor adopts steel structure, which can prolong service life.
C. Pump for water and additives delivery
The water and additives are usually pumped into the weighing hopper.
Our weighing system of stationary concrete mixing plants includes aggregate weighing, cement and fly ash weighing, water weighing and additive weighing.
The aggregate is weighed through concrete batching machine. The aggregate can be weighed separately and intensively. The separate weighing can weigh different materials in separate weighing hopper at the same time, which can achieve high weighing precision. While in intensive weighing way, different materials in the hopper have to be weighed one by one.
The cement and fly ash weighing, water weighing and additive weighing all adopt advanced weighing sensor which can ensure high accuracy.
Our concrete plants mainly use JS series concrete mixers. The JS series mixers are twin-shaft concrete mixers, which can make concrete compulsory mixing. The forced mixing method ensures that the concrete can be mixed uniformly with high quality.
Our stationary concrete plants for sale are equipped with electric control system. The whole plant can be operated through control system. The system has PLC computer and control panel, which is convenient for users to operate and maintain.
Pneumatic system is the motion execution device of concrete mixing plant. Its role is timely switching each bin, the mixer discharge door and cement weighing discharge door. It can guarantee the accurate measurement of aggregate, cement and additive and complete the loading tasks of mixed materials.

4. The cement silo is equipped with dust collecting device, which can avoid cement leakage. In closed working environment, the operation of batching plant is beneficial for environment protection.
5. Two aggregate feeding ways include belt type and hopper type. Different feeding methods can satisfy customers’ demands.
Working Principle of Stationary Concrete Batching Plant
The aggregate of sand and stone are put into PLD series concrete batcher through wheel loaders. The aggregate in the hopper can be weighed in separate or accumulated ways. After weighing, the aggregate will be conveyed to concrete mixer through belt or skip hoist. While the cement and fly ash are stored in the cement silo. The powder materials are transported to weighing hopper through special equipment–screw conveyor. Water and admixtures are stored in pond and additive tank. They both are delivered to weighing system through pumps. Same as aggregate, after weighing, powder materials, water and additives are conveyed to concrete mixing system. It will take a few seconds to finish the mixing cycle. Tough with shorting mixing time, the concrete mixture still can be mixed evenly. Generally, the finished concrete will be transported to construction sits through concrete mixing truck.
