Working principle of concrete mixer
Concrete mixer is special machinery concrete batch by uniformly mixing with a certain ratio of cement, sand , gravel(aggregate)and water prepared concrete.The main task of the concrete mixer is:
(1)uniform distribution of components to achieve macro-and micro-homogeneous;(2)destruction of the cement particle agglomeration , making each particle surface is water infiltration , prompting the development of diffusion phenomena;
(3)destruction of the initial film wrap layers of cement hydrate particle surface , promoting the combination of cement particles and other materials to form an ideal hydration product;
(4)Since the aggregate surface is covered with a thin layer of dust and clay impede the formation of interfacial layers , it should be made between multiple collisions and friction materials to reduce the impact of dust film.(5)improve the mixture of the unit body in sports croover frequency and the number of trajectories to accelerate to homogenisation.In order to obtain uniform mixing of concrete, concrete mixers must meet the following conditions :
(1)can Stir various components of concrete , asphalt and make the grout or even wrapped aggregate surface;
(2)Discharging the concrete after average stirring;
(3)material can stir and discharge for a short time;
(4)small occupying area;
(5)power consumption, in line with environmental requirements.The main factors aociated with the mixer affect the quality of the concrete mixing are:
(1)Structural forms of concrete mixer and its stirring speed;
(2)concrete mixer discharge capacity and the mixing tube geometry volume ratio, volume utilization factor;
(3)mixing blades and wear condition of liner;
(4)The order of addition of the various hybrid materials;
(5)mixing time.
