Like most machines the Construction Paste Grinder requires Hoppers for input and output. It's best used in combination with the Garbage Thief, which will remove and store unwanted Blocks into adjacent Hoppers ready to be turned into Construction Paste.
Later in the game, a Quarry is a great way to gather lots of Construction Paste due to the huge amount of natural blocks it digs up. Since Coal can also be turned into paste, mining surplus coal ore veins is a fast way to gather material for Aesthetic Blocks early on.
