As one of the equipment of the low price hzs75 stationary concrete batching plant, the concrete mixer is extremely versatile. With the advancement of science and technology, the production technology of concrete mixers has developed rapidly. There are many types of concrete mixers according to different concrete production needs and manufacturing technologies.

Among them, self-falling mixer and forced mixer are two of them. As two different types of mixers, there are the following differences:

The most commonly used mixers today are forced mixers. China JS500 concrete mixer is divided into a single horizontal shaft forced mixer and a double horizontal shaft forced mixer. The stirring amount of the forced type mixer is larger than that of the self-falling type mixer. The self-falling mixer is mainly composed of a frame, a support wheel, a mixing drum, a curved beam, a handle, and a motor.

The stirring cylinder is composed of a cone, a cylinder and a U-shaped body. The difference between self-falling mixer and forced mixer: The inner wall of the mixing bowl of the self-falling mixer has no blades. The materials are mixed by rolling the mixer drum. Arc-shaped blades are welded on the inner wall of the mixer drum of the forced mixer. When the mixer drum rotates around the horizontal axis, the blade continuously raises the material to a certain height, then falls freely and blends with each other.

Self-dropping mixer is suitable for mixing plastic concrete and low-flow concrete. The mixing effect of the discount JS750 concrete mixer is stronger than that of the self-dropping mixer. It is suitable to mix dry hard concrete and light aggregate concrete, as well as liquid concrete. The self-falling mixer relies on the rotation of the mixing tank to raise the internal concrete to the upper part of the tank, and then falls down, so that the circulation is continuously stirred. The forced mixer is a stationary tank, which is agitated and mixed inside with a stirring claw. Its effect and efficiency are better than the self-dropping type.

The mixer drum of the self-falling mixer is placed vertically. With the rotation of the mixing drum, the concrete mixture is free-falling in the mixing drum to achieve the purpose of mixing. The barrel and blade of the self-falling mixer have less wear and tear, and are easy to clean, but have large power consumption and low efficiency.

The cheap JS2000 concrete mixer has the advantages of good mixing quality, fast mixing speed, high production efficiency, simple and convenient operation, and safety. However, the machine parts are severely worn, and generally need to be lined with high-strength alloy steel or other wear-resistant materials, which are mostly used in centralized mixing stations. The self-falling mixer mainly uses the self-weight of the materials in the mixing drum to save energy. However, due to the influence of material adhesion and friction, the mixing process has a large abrasion on the concrete aggregate, which has an adverse effect on the quality of the concrete. Therefore, the self-falling type is gradually being replaced by a forced mixer.

Different types have different impacts on production. Users choose different types of equipment according to their production needs. This increases the scope of production for users. At the same time, two different types of concrete mixing station equipment Type also has some corresponding targeted production directions.
