Concrete Recycling Plants


Portable/Mobile/Stationary Recycling Plants

The choice of one or several types of these recycling plants will be determined by the project. For example, is the project a redevelopment? Is there demolition onsite? Is the site a recycle center? Rest assured there is a recycling plant to fit the project.

Mobile Recycling Plants

This type of recycling plant can be moved to various locations economically. Track-mounted plants allow superior on-site mobility.

Portable Recycling Plants

Choosing the right crusher for a particular concrete recycling project depends on several factors to be successful/profitable. What goes into the crusher, what is used to feed it (loader or hoe) and what specification final product is needed determines the size, type, and capacity of the unit / units.

1. Preparation - How much are you willing spend to prepare the material before it is ready to crush? This will determine the maximum feed size the crusher will be fed and how much steel/rebar/wood/dirt needs to be removed prior to crushing. This is typically done with hammers, hydraulic crunchers, and pre-screening. Magnets may be used to remove the loose steel.

2. Most Popular Types of crushers

a. Jaw Crushers - Jaws compress the concrete between a stationary and moveable plate. Concrete is reduced in size as it travels down the length of the wedge between the two plates. Jaws are used as primary crushers and typically produce a 4" to 8" minus product usually used as fill.

b. Impact Crushers - Impactors have a spinning rotor with bars or hammers that fling the concrete into a solid plate, several plates, or rods. Impactors can be used as primary, secondary, and even tertiary crushers and produce a product typically 2" minus used as base material in some parts of the country.

c. Cone Crushers- Cones are also compression type machines with the concrete being compressed between two cone shaped plates. Concrete feed to a cone is typically 6" minus as they are used mostly as secondary crushers behind a Jaw or Impact Primary. Cones typically produce products of 1-1/2" minus.


All of the above crusher types are available in Portable, Mobile, and Stationary configurations.

Portable crushers are mounted on rubber tired chassis, and towed to the site by truck. On site they are moved by loaders or tugs.

Mobile crushers are carried to the site by truck and trailer, and have their own on-board drive system; typically track driven. These units move easily on sites where several moves are required.

Stationary crushers are just that, they are permantly fixed to the ground. Typically used in a recycling yard where all material is trucked to the site.

Most recycling projects require the operator to produce a sized or specified end product with gradations that need to be met. The example below may help.

Job requirements - 30" minus concrete on a demo site to be reduced to 1-1/2" minus base material.

Producing the desired product could be accomplished in several ways but in all cases the final product would have to be screened. Using a jaw crusher as a primary with a screen and a cone or impactor as a secondary (2 to 3 separate units) or an impactor with a screen mounted on a chassis used in closed circuit (1 or 2 units) could also be used. In either case the material not reduced to 1-1/2" minus would be returned to the crusher until it passed the 1-1/2" opening in the screen. The circuit should also have a magnet for steel removal.
