Chassis and special equipment for concrete transportation make up a concrete agitator for sale, which is used to deliver concrete mixture for construction project. The chassis we used comes from Foton, Howo, Dongfeng, ISUZU, Sinotruck and FAW, etc. In detail, the truck is composed of PTO, front support bracket and rear support of mixer tank, reducer, hydraulic system, mixer tank, water tank, control system, cleaning system, feeding system, discharging system and so on. Among them, if the truck chassis has PTO, tank can get the power directly from truck, while if without PTO, it is necessary to install a diesel engine to ensure the smooth rotation of concrete agitator truck. Mixer tank contains tank, feeding & discharge system, cleaning system, hydraulic system, and feeding system includes feeding hopper, discharging system consists of discharging hopper, slip through, lifting rotation system and discharge chutes. For hydraulic system, it is made up of hydraulic pump, hydraulic motor, gearbox and reducer. The purpose of cleaning system is to clean the residual inside the wall and keep the normal running of the truck.
There are many concrete agitators manufacturers on the market, and it is difficult for most of customers to select a proper one for their construction project, thus, this page aims to give a brief introduction about the truck so that customers can do well in truck buying and operating. Furthermore, the concrete mixer truck capacity in our company is 3/ 4 / 5 / 6 / 8 / 10/ 12m³, and the chassis mainly is 4*2/ 6*4. You will find concrete agitator truck specifications in the end.
Working principle of concrete agitator truck
1. Feeding process. Drive the agitator truck to the construction site, actually is the discharging outlet of the concrete batching plant, and discharge the concrete mixture into the feeding inlet of the mixer truck, then the concrete materials will enter into the mixer tank through the conduit of the cylinder verge, and under the guidance of spiral blades, concrete will flow into the lower middle part of the cylinder.
2. Mixing process. Take out the power from chassis through the PTO, convey the power to hydraulic system, the power through the small transmission shaft and reducer drives
hydraulic pump, hydraulic motor and mixer tank to rotate.
3 .Discharging process. When the concrete agitatorbegins to discharge concrete mixture, engine convey the power to mixer tank through PTO, hydraulic pump and reducer, drives thee tank body to rotate, the rotational speed is 3 to 14 revolutions per minute, concrete will move to the cylinder verge under the pushing effect of spiral motion of blades, and be discharged from the discharge hopper of the concrete agitator for sale.
4. Cleaning process. Pressurizes the water tank through the air cylinder of braking system, the water after pressurizing begins to clean mixer tank system, feeding inlet, discharging system, etc.
Compositions of concrete agitator
1. Domestic made concrete agitator trucks for saleusually adopt engine power fetching. Effect of power device is to take out the power by controlling the force switch, drive mixing cylinder through the hydraulic system, during the process of feeding and conveying, mixing cylinder is rotating clockwise, which is beneficial to materials feeding and mixing, when discharging materials, the mixing cylinder will rotate anticlockwise. After work, operator should cut off the connection between the power of engine and mixing cylinder.
2. Hydraulic system. Convert the power from the engine to hydraulic energy and through the motor is mechanical energy, and provide the rotation of cylinder with power.
3. Decelerate the revolving speed from the motor in hydraulic system and deliver them to the mixer drum.
4. Control device. Control device can control the rotation direction of cylinder and the revolving speed.
5. Mixing equipment. It includes mixing cylinder and other auxiliary support units. It is made of high quality wear resistant steel plate. To achieve automatic concrete feeding and discharging, there are spiral blades with special shape welded in the inner wall of mixer tank. When rotate, concrete moves in the spiral direction of blades, under the continuous lifting and turning, concrete mixture is mixed and stirred. In the process of feeding and delivering, the mixer tank rotates clockwise, concrete moves in the inner direction along the blades, when discharge materials, mixing cylinder will rotate anticlockwise, and the concrete will be discharged out along the blades. The rotation of cylinder is ensured by the hydraulic driving device.
Mini concrete agitator for sale, whose loading capacity is 3 to 6m³, usually use motor engine, through the power-output shaft and drive the hydraulic pump, and push the hydraulic motor to drive the cylinder by the high pressure oil. And whose loading capacity is 9 to 12m³, use truck-mounted diesel engine to push the hydraulic pump and drive the hydraulic motor. Blades are key part in mixing device, damage and abrasion will cause uneven concrete. What’s more, the angle of the blades will influence the quality of the concrete, if the design of blades’ angle is unreasonable, concrete will be isolated.
6. Cleaning system. Main effect of cleaning system is to clean the mixing cylinder. Cleaning system can cool down the hydraulic system. Since concrete will solidify, in the process of transportation, the mixer tank should keep rotating, and after the concrete mixer agitator stop mixing, there are still some residual concrete left on the tank wall, so it is necessary to clean them.

The operation of water supply system
1. Open the pressure switch of the water supply device;
2. Close the air inlet cock of water supply device, open the air release valve, connect the water tank with atmosphere and add the water to the water tank. When use the water in pressure water tank, should close the air release valve firstly, and then open the air supply. If the truck stops working in winter, should clean out the residual water of water tank, pipeline and hydraulic gun in case that the spare parts of water supply system will be frozen and cause unnecessary losses.
And if you don’t need a chassis, we have many types concrete agitator bowls for sale.
