The mixing device of concrete mixer trucks for sale

The structure of a concrete mixer truck seem to be small than that of a concrete batching plant, but in fact, the technical level of concrete truck mixer is as high as batching plant. In the overall structure of concrete mixer trucks for sale, the mixing tank is the biggest part, and it is on of the the stirring device of the equipment, it is the topic we are going to learn about. The mixing device is mainly composed by the mixing drum and its supporting components.

Mixing drum is a concrete loading container of a concrete mixer truck, which is made of high quality wear-resistant steel plate, in order to automatically loading and unloading concrete, the inner wall weld special shape spiral blade. Concrete moves along the helical direction of the blade during rotation, and is mixed and agitated during constant lifting and turning. In the process of feeding and transporting, the mixing drum rotates forward and the concrete moves inwards along the blades. When the concrete material is discharged, the mixing drum reverses and the concrete is discharged outwards along the blades. Mixing drum rotation is driven by hydraulic. The concrete mixer trucks for sale with loading capacity of 3 to 6 cubic meters generally adopts hydraulic pump driven by car engine through power output shaft, and then driven by high pressure oil to drive the mixing drum. The loading volume of 9 to 12 cubic meters and is driven by an auxiliary diesel engine hydraulic pumps drive hydraulic motors. The blade is the main part of the mixing device, damaged or severely worn will result in uneven mixing. In addition, if the design of blade angle is not reasonable, the concrete appear segregated.
