The　La(Fe11.2Co0.7Si1.1)B0.25　alloy　ingot　was　crushed　into　small　particles　with　diameters　less　than　1　mm,　and　the　particles　were　further　milled　in　a　planet　ball　grinder　for　1　h,　1.5　h　and　2　h.　The　spark-plasma　sintering　(SPS)　technique　was　adopted　to　fabricate　the　sintered　samples　at　1070°C　for　1　h.　The　phase　composition,　microstructure　and　magnetocaloric　properties　were　examined　by　XRD,　SEM　and　VSM.　The　results　show　that　the　cure　temperatures　of　the　sintered　samples　decrease,　the　adiabatic　temperatures　and　isothermal　magnetic　entropy　changes　rise　with　the　increasing　of　milling　time.
