MOX powder forming agent and lubricant adding method

The invention relates to a MOX powder forming agent and lubricant adding method, which comprises: 1, selecting zinc stearate; 2, drying the zinc stearate particles for 0.5-3 h at a temperature of 15-40 DEG C under a vacuum degree of 0.01-0.5 Pa so as to remove the volatile impurity elements and avoid the abnormal particle size increase and the melting caused by the too high temperature; 3, screening the zinc stearate particles treated in the step 2 with a 20-100 mesh screen sieve; 4, calculating the required MOX particle amount at a loading rate of 15-35%, adding to a ball mill tank, adding the zinc stearate particles treated in the step 3 to MOX particles according to a weight ratio of 0.02-5.0%, and introducing 15-38 DEG C cooling water at a speed of 5-15 L/min so as to avoid the agglomeration and melting caused by the material heat generation; and 5, mixing for 5-45 min at a speed of 1-10 r/min to achieve the primary uniform mixing of the zinc stearate particles and the MOX particles, gradually increasing
