Diesel concrete mixers are mobile type, very convenient to move anywhere. The drum rotates in one direction for mixing and in the opposite direction for discharging the concrete. There are two types of blades attached to the inner walls of the drum. One set drags the concrete upwards and toward the center of the mixer when the drum rotates in one direction; the second set of blades pushes the concrete toward the opening when the drum rotates in the other direction. The blades have a spiral arrangement to obtain the desired effect for discharging and mixing. Diesel concrete mixers are suitable for mixing plastic and low-slump concrete. It is widely used in roads, bridges, water projects or other industrial and civil projects, specially most popular in tight-electricity countries.
Diesel concrete mixer has the characteristics of cold resistance, high temperature resistance and high pressure resistance. In order to use diesel concrete mixer for a long time, it is necessary to maintain well the machine. Diesel concrete mixer is different from electric concrete mixer. You should pay special attention in its use and maintenance process.
Concrete mixer has been existed for a long time, and the earliest concrete mixer was invented after the birth of steam engine, which was basically motored by steam power. From then on, the world emerged a variety of concrete mixers in 1950, and also concrete mixers were divided into self-falling concrete mixer and compulsory concrete mixer at that time.
