Self loading concrete mixer machine is a small-scale portable concrete batching plant. It combines self loading, self weighing, automatic water supply, self mixing, self discharging with short-distance transportation, replacing partial functions of loader, mixer and concrete truck.
Now more and more small and medium-sized enterprises choose to use it. Due to its compact size, the off-road tires and good gradeability, self loading concrete mixer machine has been used in the infrastructure construction such as roads, buildings, bridges, tunnels, floors, slope protection in rural areas, mountainous areas and other areas.
Types of Self Loading Concrete Mixer Machine
Two main types of self loading concrete mixer machines:
- Pan-type self loading concrete mixer
- Drum-type self loading concrete mixer
Pan Self Loading Concrete Mixer Machine VS. Drum Self Loading Concrete Mixer Machine
- The cab is located in the middle of the pan-type self loading concrete mixer, making the driver’s field of vision wider and the operation easier.
- The cab of drum-type self loading concrete mixer machine is outfitted with two-way driving , and the mixer can rotate up to 270 degrees.
- Compared with the pan-type self loading concrete mixer, drum-type self loading concrete mixer has a larger production capacity.
- The raw materials in the drum-type self loading concrete mixer are raised to the upper part of the drum , then are fallen. The mixing process will last for minutes like that until the concrete is produced.
- Pan-type self loading concrete mixer is a forced mixer which can stir liquid, semi-dry and dry hard concrete.
- Drum-type self loading concrete machine mainly produce plastic concrete to meet most construction needs while pan-type self loading concrete mixer produce semi-dry concrete.

The Components of Self Loading Concrete Mixer Machine
Self Loading System
Self loading system is mainly completed by the loading arm which can carry out a series of loading and unloading. The driver in the cab operates the arm to drop the shovel.
After shoveling the materials, the driver handles the arm again to lift the shovel to the mouth of the drum,then opens the bottom of the bucket, and the materials are accurately poured into the drum.
Generally speaking, only two workers are required to finish the work. One worker is in the cab, another outside the cab does some supporting work.
Self Weighing System
The weight sensor is installed on the loading arm to measure the weight of cement, sand and gravel,which solves the problems of the dosage of the raw materials, makes the high-quality concrete meet the national standards.
Automatic Water System
Self loading concrete mixer machine is not only equipped with suction pump and large capacity tank, but also equipped with automatic water system.
After the tank is filled with water, the driver operates the pump in the cab, then water in the tank can be injected into the stirring drum, mixing with other raw materials.
Self Mixing System
The hydraulic system of self loading concrete mixer machine gets power from the diesel engine, transfers the power to the hydraulic pump through transmission shaft.
The high pressure oil in the hydraulic pump drives the motor, and motor transfers the power to the reducer, at the same time the mixing drum rotates in the positive and negative directions, thus realizing the stirring and discharging process.
Self Discharging System
The stirring cylinder unloads the concrete by rotating counterclockwise. The discharge port can rotate up to 270 degrees, increasing the spread area and improving work efficiency.
The unloading chute is tilted by a manually adjustable handle and can be rotated 90 degrees, but cannot be synchronized with the tilting operation of the stirring drum. Detachable chute ensures direct unloading through the hopper.
The torque converter gets the power from the diesel engine, then supplies the power to the gearbox. The drive shaft powered by the gearbox controls the machine’s movement.
In general, self loading concrete mixer is only suitable for short-distance transportation, and can’t be used as a transport vehicle.

The Price of Drum-type Self Loading Concrete Mixer
Prices of drum-type self loading concrete mixer range from $15,000 to $70,000 according to the model and capacity.
The minimum output of concrete mixer is 1.2 m³per batch, and the maximum output is 6.5 m³per batch. Three to six batches can be produced per hour.
The production of concrete can be about 500 tons one day which basically meets the needs of medium projects.
The Price of Pan-type self loading concrete mixer Machine
The prices of pan-type self loading concrete mixer machine range between $15,000 and $29,000 because of small capacity.
The capacity of the two models is 1.2 m³and 1.6m³respectively. It can also be designed according to the customer’s needs.
The daily output of the pan-type self loading concrete mixer is enough to meet the needs of small engineering projects.
What Influences The Price Of Self Loading Concrete Mixer?
1. Supply and demand in the market
If the market demand for self loading concrete mixer machine is greater than the supply of manufacturers, the price of the mixer will naturally rise. On the contrary , the price of the mixer will go down.
2. Price of the raw materials
Steel is the skeleton of the self loading concrete mixer machine, so a set of mixer is 90% steel. A small increase in the price of the steel will greatly affect its ex-factory price. Especially the special steel amount of the wear-resistant and corrosion-resistant mixer directly determines the price of the mixer.
3. Quality of the self loading concrete mixer machine
Quality is the main factor in determining the price. The better the quality , the higher the price. Users should not only care about the price of the equipment, but also pay more attention to the quality of equipment to avoid buying defective mixers.
4. After-sales service
The service life of the self loading concrete mixer is generally as long as ten years. There will inevitably be some small troubles influencing the production efficiency in the process of use.
The supporting service of the self loading concrete mixer provided by the manufacturer is also an important factor in affecting the price.
5. Regional difference
There are also differences in the price of the self loading mixer machine in different regions. If users buy machines in the regions where there are fewer manufacturers, there is no doubt the price will rise.
So consumers should do their best to research the price in each region and then find the most suitable machine for themselves.
6. The influence of manufacturers
The price of the self loading mixer machine varies from manufacturers to manufacturers.
In many cases, the equipment produced by a large famous manufacturer is more expensive than the equipment produced by a small manufacturer, because large manufacturers have advantages in production technology, and the quality is guaranteed.
7. Technology content
Although different manufacturers have same self loading concrete mixer machine , the high-tech mixer is expensive naturally.
But the high-tech mixer has good performance, higher mixing quality and longer service life. Customers should make choices according to their actual needs, do not blindly purse high-tech machines.
