Regeneration machine is an important equipment for regeneration of old sand in foundry production, removing the inert film on the surface of old sand grains, so that the old sand can meet the requirements of reuse. Regeneration machine can be divided into two kinds according to different working principles:
Centrifugal regeneration machine:
Using mechanical centrifugal regeneration method to remove the inert film on the surface of old sand grains, this product has the advantages of less sand crushing, high regeneration efficiency, less wearing parts and high service life, simple maintenance, small footprint and so on compared with other equipment.
The regeneration machine is a secondary or tertiary regeneration, the screened old sand, through the magnetic separator into the regeneration machine, the falling sand particles in the rotor disk after self-grinding accelerated ejection to the upper, middle and lower retaining ring, after the collision left behind, and then through the throttle ring and the rotor between the grinding falls into the second/third level regeneration mechanism, repeat the above process, to remove the inert film on the surface of the sand particles to achieve the purpose of regeneration, regeneration of the sand drop to the wind sorting device, the regenerated sand. After wind sorting to separate the sand from the micro powder, so that the old sand reaches the purpose of recycling.
Grinding disk type regeneration machine:
Grinding disc type regeneration machine is used to regenerate the old sand of resin sand, utilizing mechanical centrifugal boiling + grinding method to remove the inert film on the surface of the old sand grains, which has the features of less sand crushing, high regeneration efficiency, rounded shape of regenerated sand, less wearing parts and high service life compared with other regeneration machines. Simple maintenance, small footprint and other advantages. This equipment is improved according to the environment of high temperature, the lubrication method is thin oil lubrication, external oil cooling circulation system, to extend the service life of bearings.
The screened old sand enters the regeneration machine through the magnetic separator, and the falling sand grains fall on the movable disk, and then ejected to the fixed disk, and after the friction between the sand grains and the grinding disk and the friction between the sand grains and the sand grains, the inert film on the surface of the sand grains is removed, so as to achieve the purpose of regeneration.
