The HD furnace is a kind of machine that crush ingot or chip into powder through the reaction of hydrogen and Nd2Fe14B rather than mechanical force. The furnace adopts total automatic operation program and can finish hydrogen absorption and dehydrogenation in 600 degree circumstances.

Advantages:
3-4 times crushing capability than general machinery;
The mterial is stable and homogeneous;
Small particle size and homogeneous;
The time for dehydrogenation get shoter;
Low cost, less investment but high yield;
