Amazon also sells 1/12" gauge sifters with ASIN B00B3KPT7U and 1/8" with ASIN B008B0TJAI (both include free shipping for about $15.00)
You need a second bin or container and a trash can for sifting. You'll scoop up worms/bran out of your growing bin and shake it while tossing to let any castings fall through the bottom into the trash (or a third bin if you want to keep them). It's okay if some bran passes through too, you'll be adding fresh. Place the cleaned worms into your second bin. Continue this until all you have left is the castings in the bottom of the bin, they'll look like dark sand. Tip them out with the rest of your castings. Now you can add your sifted worms and bran back into their bin and add fresh bran if needed. The castings make excellent fertilizer! You can sprinkle it on your lawn or around your plants outside. You can also make a 'tea' and water your indoor plants with it as well.
