Ready Mix Concrete Mixer Vehicle Journal Sticking Analysis

Recently some of our readers asked whether there are ready mix concrete mixer vehicles of twin horizontal shafts without journal sticking problems, because they have bought from other suppliers such mixers with the very irritating problem. The answer to the question is positive. A ready mix concrete mixer has journal sticking problems just because it has been designed unreasonably.

The possible reasons for journal sticking of a concrete mixer vehicle include unreasonable design of mixing devices, dislocation of washing points, wrong washing direction, low water pressure and inappropriate usage rate of the tank volume. Unreasonable design of location and direction of concrete and powder material feeding mouths will lead to large amount of powder getting onto the shafts, which is known as the phenomena of journal sticking. Wrong washing direction, point or force will result in failure in complete cleaning of concrete stuck onto the mixer devices as well. Excessively low usage rate of the mixing tank volume makes the raw material level lower than mixing shafts so that part of concrete get stuck onto the shafts without getting mixed again and again as the other part of raw materials.

Then how to solve the problem of journal sticking of ready mix concrete mixer vehicles? First, the cement and powder feeding mouths should be located between two mixing shafts and the outlet direction should be along the shafts. During the manufacturing of the mixer, do make sure that the water spraying device is welded onto the right place and that the water supply system should be designed with stable pressure. Solutions include increasing special booster pump or adopting high water level water tank. Raising volume usage rate of the mixing tank proves to be the most difficult part. After years of exploration and experimentation, we are now able to supply twin shaft concrete mixers without journal sticking problem. Welcome to contact us for more information!
