Primary recycling, also known as closed loop recycling, is the process of turning one thing into more of the same thing, like paper into more paper or soda cans into more soda cans. Secondary recycling means turning something into other things made of the same material in essentially the same form.

GRINDING WHEELS MADE FOR ALL METALS. Grinding wheels are mixed combinations of resin and abrasive grains. The abrasive does the work and grinds metal when it makes contact with metal surfaces, while the bond holds the abrasives in place and helps the wheel keep its shape. Abrasives vary in strength and hardness.
