What is the difference between mortar machine and concrete machine?

November 08, 2018

We believe that most people outside the industry will not be able to distinguish between mortar machines and concrete machines. They think that the two machines are the same and can be mixed, but it is not. The composition of mortar and concrete is different, and the structure of the machine is relatively different.

Cement mortar is a mixture of cement, sand and water. It has no aggregates, does not form a strong skeleton, and is difficult to withstand strong loads. In construction engineering, the use of cement mortar, first, foundation and wall masonry, used as a binder for block masonry materials, such as masonry, red brick to use cement mortar; second, for indoor and outdoor wipes gray.

Concrete is a general term for engineering composites in which aggregates are cemented into a whole by a cementitious material. Ordinary concrete is made of cement, coarse aggregate (gravel or pebbles) fine aggregate (sand). An artificial stone that is mixed with water and hardened. Concrete has the characteristics of workability, high strength, deformability and durability.

The difference in material results in a different machine construction. A mortar mixer is a machine that mixes cement, sand aggregate and water and mixes them into a mortar mix. It mainly consists of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and support device. The mortar mixer equipment can meet the production requirements of dry powder mortar, dry powder material and dry powder binder, such as putty powder, dry powder coating, masonry mortar, plastering mortar, mortar required for insulation system, decorative mortar, etc. Dry powder mortar; and has many advantages such as small footprint, low investment, quick effect, simple operation and so on.

The working principle of the mortar machine is: when the machine is working, the material in the machine is subjected to two opposite directions of the rotor, and the compound movement is carried out. The pulp leaves are rotated counterclockwise along the inner wall of the machine groove, and the animal material is turned around. In the weight loss zone where the two rotors overlap and overlap, in this zone, regardless of the shape, size, and density of the material, the material can be floated in an instantaneous weightless state, which causes the material to form an all-round continuous cycle in the machine slot. Interlaced with each other to achieve a fast, gentle mixing and uniform effect.

A concrete mixer is a machine that mixes cement, sand aggregate and water and mixes them into a concrete mix. It mainly consists of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and support device. The utility model comprises a power mechanism connected to the transmission mechanism through a shaft and a roller driven by the transmission mechanism, wherein a ring gear disposed around the drum cylinder body is mounted on the drum cylinder body, and a gear meshing with the ring gear is arranged on the transmission shaft. The utility model has the advantages of simple and reasonable structure, and the gear and the ring gear are meshed, which can effectively overcome the slip phenomenon between the roller and the mixer drum in the rain and fog weather; the adopted transmission mechanism can further ensure the elimination between the roller and the mixer roller The phenomenon of slipping.

The working principle of the concrete mixer is to make the composition components macroscopically and microscopically uniform, to destroy the phenomenon of cement particle agglomeration, to promote the development of dispersion phenomenon, to destroy the initial hydrate film wrap layer on the surface of cement particles, to promote collision friction between material particles and reduce dust. The influence of the film increases the frequency of the movement of each unit of the mixing material and the crossover frequency of the motion trajectory, and accelerates the homogenization.
