Shredder

The Shredder is used to shred (or pulverize) materials. Can shred 9 items simultaneously.

Needs x2 Shredder Blades and power to operate. Consumes ~300HE per operation.

Usage
Put the two blades in their slots, then fill the 9 slots above with whatever items you want turned into powder.

It will turn everything in those slots into powder at the same time, so you can shred several different items at once. This is highly recommended even when shredding stacks of the same item as you will use less power, time, and blade durability.

If ore is placed inside, you will receive 2 of the dust form of the item, which can be smelted into 2 ingots of the item. Though overall inferior to the centrifuge in this role, as it doesn't use blades that have to be replaced, and produces up to 3 or 2 with a secondary output, it is good for early gameplay for more efficient ore processing or processing a significant amount of 1 or more ores.

Trivia

 * If a non-metal is shredded (e.g. diamond, emerald), it cannot be smelted back into normal form. You'll have to use a press to do that.
 * If you add an item into an empty spot in the shredder while it is still undergoing an operation, the added item will be shredded without any added power, time, or blade durability consumption.
 * If an item without a powder form or otherwise designated output, it will turn into scrap. So please, use NEI to check the recipes before sticking random items inside.
 * Scrap can be used as furnace fuel for 4 operations or turned into blocks (4) for 20 operations. Useful for ridding yourself of useless or dangerous items.
 * If scrap is re-shredded, it will turn to dust, which can also be used as furnace fuel (2) or turned into scrap blocks (9 instead of 4). Doing this is pointless as dust is inferior to normal scrap and just wastes blade durability and power.
 * Dust can also be made by shredding a powder that does not have a designated output.
 * There is a curious yet exploitable bug/error where if you shred a Fluxed Electrum ingot from Thermal Expansion: Redstone Arsenal, it will yield  2  dust instead of 1. These 2 dust can be put back into an Induction Smelter (also from TE) and made into 2 ingots, allowing for the process to be repeated.
 * This will likely be fixed in the future however, so don't depend on it.
