A kind of pre-treatment process of brick manufacturing which includes the following steps: 1. Once surface spreading: supply the material in proportion into the cylinder and make it spread to eliminate the magnetic material or magnetic inductive material 2. Harsh comminution: smash the large clod in the material after once surface spreading 3. Twice surface spreading: spread the material after comminution again, to eliminate the magnetic or magnetic inductive material 4. Spare comminution: smash the material after twice surface spreading to form particles with the same diameter 5. Add the bonding and with agitation: add water in proportion as the bonding to provide the brick material as less hydrated 6. High pressure leavening: stack the brick material to at least six meters for one to fifty days so as to generate natural high pressure leavening process to get the homogeneous plastic coefficient and mutual bonding reaction 7. Small amount water agitation: add water to control the hydrated ratio below 20% for the following extrusion, cutting, hydration and firing process.
