Jaw Crusher, also known as concrete crusher, is usually used as the primary equipment for concrete crushing. It is also suitable for metallurgy, mining, construction, chemical, water conservancy and railway sectors, and used as a device for fine and medium crushing of ores and rocks with compressive strength below 250 Mpa.

Use a sledgehammer for thin slabs. If your concrete is 4 in (10 cm) thick or less, try using a sledgehammer. Start at any existing cracks or at a corner or edge, and keep in mind that thick concrete will be easiest to break closer to its outer edges. Don't try to swing the sledgehammer or lift it above your head; hold it at shoulder-height and let it fall onto the concrete, instead.

The first step to recycling old concrete is to use industrial crushing equipment in order to break up the original structure. Next, the broken up concrete is run through a secondary impactor. After being crushed to an even smaller size, the crushed concrete is then screened so that dirt and other foreign objects can be removed.
