High quality and efficiency of Deswell concrete mixer in Henan

There are many concrete mixer manufacturers in Henan. How to choose a good concrete mixer from numerous factories? Henan Daswell Machinery Co., Ltd is a manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years.

Now, I’d like to introduce the unique function of concrete mixer in Daswell.

The concrete mixer is used for production to meet the various needs. The machine must not only meet the technical standards, but also must be able to adapt to a variety of terrain conditions. The design of machines and components needs according to different require, which a very important one: automation systems need to have a high level of flexibility to machine technology functions to modify, add and extend machine technology functions to modify, add and extend.

Concrete mixing system consists of a variety of independent units and processes.

Control system

The task of control system is to ensure safe and reliable mixing operation. It mainly controls the gating system of the motor and mixer header. The indirect drive control of the mixing tube is necessary.

The aggregate

The aggregate is weighed in the discharging chute or measured by the strain sensor on the conveyor. If you use aggregate trucks, they are controlled by transducer, the end position inductor and security terminal position inductor. The aggregate silo includes one or two vibration devices to ensure charging accurate. During higher demanding applications, the amount of aggregate in the silo is measured by the radar sensor. If necessary, the radar sensor is also used to measure moisture of the sand. With the acquisition of measurement data, you can adjust accordingly concrete pre-mixing process.

Water measurement

Firstly, the water is weighed by the weigh machine with two control valves; then it is measured more accurately by the parallel flow meter.

Adding accessories

The concrete produced according to the specific requirements of different applications, so, its characters are not the same. Nowadays, it is difficult to imagine that no any ingredient to use in the concrete producing process. These few accessories are added by using pump and the weighing machine.

Nowadays, many concrete mixers provide consistency measuring device. In addition, the mixing system is also equipped with microwave sensors and temperature sensors for humidity measurements.

Analysis the reasons for concrete mixer shaft stalling

A concrete mixer is a powered device that mixes cement with water and aggregate, such as sand or pea gravel, to make concrete. Concrete mixers range from the very large commercial mixing truck to the smaller, portable concrete mixer sometimes called a “mini mixer”. A concrete mixer is comprised primarily of a motor, a rotating drum, and often a chute. Inside the drum, the materials used to make concrete spin around, mixing together evenly and remaining soft for application and forming.

Concrete mixer can mix hard concrete, plasticity concrete, liquidity and lightweight aggregate concrete and various grouts, mortar. It is a high efficiency machine and often used for big, middle, small size precast components factory and road, bridge, water conservancy, etc.

When using concrete mixer, sometimes there will be something wrong with the shaft. Today, our technical personnel will tell you why the shaft stops and how to deal with it.

1. The electrical machine rubber belt is too loose


If the electrical machine rubber belt is too loose, it will lead to transitive power short. Even smaller load also can lead to mixer shaft stalling.


If rubber belt too loose leads to mixer shaft stalling, it needs stop machine and adjust the tension device to strain rubber belt.

2. There are big foreign material between pot wall and mixing blade or side blade


Between pot wall and mixing blade or side blade having big foreign material can also make mixer shaft stalling. The reason of storing foreign material is the excessive gap between pot wall and mixing blade or side blade.


When appearing this trouble, it needs stop concrete mixer immediately to check and worker gets rid of foreign material, and readjustment the gap between pot wall and mixing blade or side blade.

3. Serious overload


Mixer shaft exceed regular workload can make it move slowly. If the load is too big, it can make mixer shaft stall.


If overload cause mixer shaft stalling, it needs adjust the charging rate, discharge redundant material and reduce the mixer shaft running load to make it normal running.

What can we do to ensure concrete quality

During the process of concrete mixing equipment production, each link executing agency works orderly under the control of automatic control system, but due to the production site environment factors: vibration, temperature and humidity may lead to a failure executing agency of a certain link, such as the host repeated feeding, slump out of control, excessive additives, and so on, thus affecting the quality of the concrete.

In order to ensure the concrete quality, there are the following protection measures:

1). According to the different mechanical structure and properties of materials, slow batching value, the drop value, and buckles that amount will be automatically adjusted in advance, or you can manually adjust the weight change detection and zero-tracking capabilities.

2) Measure scale and mixing cylinder have memory protection function during the time of power failure, and this effectively prevents second feeding.

3) Professional zero and indexing sign protection effectively prevent the wrong adjustment.

4) Software logging in and electronic scale adjustment need the user’s password, this effectively ensure the security of important production data.

5) Automatic repairing scale: when the weighing value < desired value allowable error, the system automatically opens ingredients agencies to fill repairing scale functionality.

6) Improved automatic distribution form, automatically equal distribution ingredients, reducing the fluctuations in the fall to improve measurement accuracy.
