A concrete mixer is a machine that mixes cement, water, and other materials to make concrete. It has a rotating drum that mixes the ingredients together. 

How it works

• The concrete mixer's rotating drum mixes the ingredients together. 
• The concrete mixer can be powered by an electric motor or a combustion engine. 
• The concrete mixer can be stationary or portable. 
• The concrete mixer can be used to produce concrete on-site. 

Uses 

• Concrete mixers are used in construction to make concrete for roads, bridges, high rises, canals, and more.
• Concrete mixers can save time and labor on construction sites.
• Concrete mixers can reduce the formation of cement lumps.

Types of concrete mixers 

• Portable concrete mixers: Smaller mixers that can be transported by hand and used for smaller construction sites
• Truck mixers: Concrete mixers mounted on trucks that transport concrete to construction sites
• Batching plants: Concrete mixers used for large construction sites
