lets start from the beginning what coin and kernal did you mine and it worked?
did you download sgminer from that coin project? (could be they lightend it so it only have that algorithm in the kernel folder)

.bin file is something sgminer has in it to know how to mine a coin, if it doesn't have that .bin file for that coin then you can mine that coin/kernal
.bat file is where you put user setting and mining settings

if your missing the .bin file then its either been deleted or been removed by the people you downloaded the file from, sgminer can be downloaded in full with all the kernals and stuff from https://bitcointalk.org/index.php?topic=632503.0
