in Concrete
Concrete is a construction material composed of cement (commonly Portland cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravels or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures.

Hardened concrete that has been processed for reuse, usually as aggregates. Concrete recycling is an increasingly common method of disposing of concrete structures. Concrete debris was once routinely shipped to landfills for disposal, but recycling is increasing due to improved environmental awareness, governmental laws, and economic benefits.

Reinforced concrete contains rebar and other metallic reinforcements, which are removed with magnets and recycled elsewhere. The remaining aggregate chunks are sorted by size. Larger chunks may go through the crusher again. Smaller pieces of concrete are used as gravel for new construction projects. Aggregate base gravel is laid down as the lowest layer in a road, with fresh concrete or asphalt placed over it. Crushed recycled concrete can sometimes be used as the dry aggregate for brand new concrete if it is free of contaminants, though the use of recycled concrete limits strength and is not allowed in many jurisdictions.

SBM machinery, which is a professional manufacturer of concrete crushing equipment, provides concrete crushing equipment, concrete crushing machine and concrete crushing plant for sale, hire, rental. If you have concrete need to be crushed or recycling, you can buy or hire our concrete crushing plant.

SBM concrete grinding machine can be used in clean and prepare concrete, level uneven surfaces, remove epoxy, urethane, paint and coatings. Clean glues and mastics left over after old floor coverings are removed.

SBM concrete grinding equipment is virtually maintenance-free. The roller bearings and gearbox need not be lubricated. The air inlet and outlet should be blown out from time to time to avoid clogging. Failure to do so may result in stress being put on the machine by overheating.

If the brushes are to be replaced, the motor housing may be opened only by qualified service-personnel. Subsequent mounting of the new brushes require specialist knowledge.

SBM Concrete Grinding Machine is a high performance, plug style, dual head grinding and polishing machine. This concrete grinding tool features a 22" grinding path, removable weights and two head pressure settings. Using two sets of rear wheels, the machine can apply light head pressure for polishing applications or with the turn of a handle, can apply the machine's full weight for aggressive removal.

For concrete cleaning, coating removal, leveling and planing, and profiling
Optional slicing/polishing kit for removing elastomeric and rubberized coatings, adhesives,
and for polishing
Extendable flip out handle for increased control
Floating bubble level helps ensure a level finish is achieved
MORFLEX couplers for even and controlled grinding even on rough surfaces
