Concrete mixer. Types of mixers

Mixer is designed for uniform mixing cement with water and various fillers: grit, screenings, slag, limestone, sand, etc. Currently, the technology of preparation of various cement mixtures used dvaprintsypa rabotysmesiteley: gravitational (free) and forced action. Gravitational mixing is carried out in a rotating drum equipped with blades, by repeatedly lifting and gravity of the mixture components. The design of gravity type concrete mixers allows to analyze the concrete mixer into several parts. (During transport, etc) Concrete name BM-120 BM-250 - their small dimensions make it possible to use them on small areas (inside buildings, basements, roofs, etc.). In the gravitational concrete mixers blades for mixing a solution (concrete) set in position to achieve a homogeneous composition of the mixture and make cleaning the tank and the blades themselves with simultaneous assurance of concrete from sticking. The main advantage of concrete mixers (betonorastvorosmesiteley) gravitational action is the possibility of mixing a mortar, and hard concrete mixtures. Compulsory Mixer type characterized by a high intensity of exposure to the mixed material. The process of mixing them by means of four spider vanes. Forced type concrete mixer - Flasher machine with a fixed capacity. Moving the gate facilitates unloading of the concrete. The principle of mixers cement, sand the other components of the solution is poured into an open tank mixer, and then turn drive the blades and the solution was prepared for 5-15 minutes. After the solution ready and turn off the drive capacity mixer easily topples - mortar (concrete) is poured for future use.
