One of the methods for making recycled paper available online has the following steps,
tear waste paper into small pieces
using a blender a to make a slurry of the waste paper
pouring the slurry on a fine wire mesh so that all the water is drained and only recycled paper is remaining
The mixer, blender jar which will be used for making slurry cannot be used for other applications like food preparation, so the cheapest model is recommended
The cheapest mixer grinder available online is the Pigeon 550 W mixer grinder with 3 jars. It operated satisfactorily without any load, now it has to be tested with a load.
