【Abstract】 The effect of particle size adjustement and agregating on the bulk density and flow rate of MQ-J powder and properties of the bonded magnets is investigated.The results indicate that particle size adjustment can improve the bulk density and flow rate of magnetic powder.A certain amount of aggregating agent can remarkably improve the bulk density and flow rate of magnetic powder and the properties of bonded magnets.The appropriate content of the aggregating agent is 0.30wt%.更多还原
