A feed assembly supplies polysilicon to a growth chamber for growing a crystal ingot from a melt. An example system includes a housing having support rails for receiving one of a granular tray and a chunk tray and a feed material reservoir positioned above the support rails to selectively feed one of either the granular tray or the chunk tray. A valve mechanism and pulse vibrator are also disclosed.
