What is the working principle of self-loading concrete mixer?

2025-06-06 15:48:27

Self loading concrete mixers are indispensable key equipment in the modern construction industry. Through efficient and precise mixing processes, they uniformly blend raw materials such as cement, sand and gravel, water, and additives to provide high-quality concrete materials for construction. With the acceleration of urbanization and the continuous advancement of infrastructure construction, the demand for concrete mixers continues to grow, becoming a core driving force for the development of the construction industry.

This article will provide a comprehensive analysis of the working principles, technical features, market trends, and future development directions of concrete mixers, helping readers gain a deeper understanding of the important role this equipment plays in the construction industry.

Working Principles of Concrete Mixers

The working process of a concrete mixer can be divided into three main stages: loading, mixing, and transportation.

  1. Loading Stage

Mixers are equipped with built-in buckets or hoppers that can directly scoop sand, gravel, cement, and other materials from raw material storage areas. Some advanced models also support automatic cutting of cement bags or connection to bulk cement conveying systems, further enhancing operational efficiency. Additionally, mixers typically feature water tanks that automatically add the appropriate amount of water based on pre-set concrete mix ratios.

Technical Highlights:

Automated loading system reduces manual intervention.

Precise water volume control ensures stable concrete mix ratios.

  1. Mixing Process

After loading is complete, the raw materials are fed into the mixing drum. The mixing drum is fitted with mixing blades that rotate to thoroughly mix the materials. There are two types of mixing methods:

Free-fall mixing: Materials are lifted by gravity and fall freely, suitable for concrete with high flowability.

Forced mixing: Mixing blades forcefully flip and compress the materials, suitable for dry, hard concrete and mortar, achieving more uniform mixing results.

Technical Advantages:

Forced-mixing machines are highly efficient and suitable for various concrete types.

Free-fall mixing machines have a simple structure and low maintenance costs.

  1. Transportation and Unloading

After mixing is complete, the mixer can be transported to the construction site. During transportation, the mixing drum rotates slowly to prevent concrete layering or hardening. Upon arrival at the designated location, the concrete is discharged into the mold or pouring area via a control device.

Technical Features:

The mixing drum can be tilted or equipped with a conveyor belt for precise unloading.

Integrated mixing and transportation design enhances construction efficiency.

Technical Features of Concrete Mixers

Concrete mixers are widely used in the construction industry due to their efficient, energy-saving, and environmentally friendly technical advantages. The following are their main technical features:

Efficient Mixing: Advanced mixing technology and blade design ensure uniform concrete mixing and reduce mixing time.

Environmental Protection and Energy Saving: Low-energy consumption design, low-emission technology, and the application of new energy sources (such as electric or hybrid-powered mixers) are becoming industry trends.

Multi-functional integration: Some mixers integrate functions such as automatic batching and automatic cleaning to meet complex construction requirements.  

Intelligent control: Through IoT and sensor technology, real-time monitoring and automatic adjustment of the mixing process are achieved, enhancing production efficiency and safety.  

Modular design: Facilitates equipment maintenance and upgrades, reducing operational costs.
