This paper compares the use of jaw and impact secondary crushing for producing coarse recycled aggregates from concrete wastes, obtained from road pavement and demolished building materials.

The grate cooler is a quenching type cement cooler applied for the cement manufacturing plant. According to the movement mode of the grate, the grate cooler can be divided into three types, rotary type, vibrating type, and push-type grate cooler, with the development of cooler technology, push-type grate cooler is considered the most common clinker cooler in the cement production …

A primary crusher breaks up large pieces of rock or concrete from the blasting or excavation process and turns them into smaller, more manageable chunks. This is the first step in the crushing process. The smaller pieces can then either be …

Where the material is not reduced sufficiently in the primary crusher, it is then crushed by a secondary crusher to achieve the correct size of the material. Wear on parts of the crushers affect the performance and volume of material being …

Types of Concrete Crushers. Jaw Crushers: These robust crushers utilize powerful jaws to exert pressure, effectively breaking down concrete into smaller chunks.They excel in both primary and secondary crushing, making …

Jaw crusher is suitable for crushing all kinds of ores and rocks whose compressive strength limit is less than 250 mpa. It is mainly used as the primary crusher or secondary crusher in cement plant and concrete industries. The jaw crusher is divided into three types according to the width of the feeding port: large type, medium type, and small type.

In concrete recycling with high volume, one may consider using a jaw crusher as the primary to handle the large chunks and nasty input material. After the jaw crusher one may place a secondary impact crusher to handle smaller chunks and reduce the material further.
