Sand and aggregate are essential materials for the construction industry. The demand for high-quality sand and aggregate is increasing day by day, as construction projects are being undertaken all over the world. Sand aggregate production involves crushing and screening of raw materials, which are then processed into various sizes and shapes for use in construction projects. In this article, we will discuss the various types of crushing equipment used in sand aggregate production.
Jaw Crusher:
Jaw crushers are one of the most commonly used types of primary crushers in sand aggregate production. They are designed to crush hard and abrasive materials, such as granite, basalt, and quartzite. Jaw crushers consist of a fixed jaw plate and a moving jaw plate. The materials are crushed between the two plates as they move towards each other. Jaw crushers are capable of producing high-quality sand and aggregate with a uniform shape and size.
Impact Crusher:
Impact crushers are used to crush softer materials such as limestone, gypsum, and clay. They are ideal for producing sand and aggregate for concrete and asphalt production. Impact crushers work by throwing the material against a hard surface, causing it to break into smaller pieces. They are available in both horizontal and vertical shaft designs. The horizontal shaft impact crusher is commonly used for primary and secondary crushing, while the vertical shaft impact crusher is used for tertiary and quaternary crushing.
Cone Crusher:
Cone crushers are commonly used in secondary and tertiary crushing stages in sand aggregate production. They are ideal for producing high-quality sand and aggregate with a uniform shape and size. Cone crushers work by compressing the material between a moving cone and a fixed cone. The material is crushed and then discharged through the bottom of the machine. Cone crushers are available in various sizes and configurations to suit different applications.
VSI6X Crusher:
VSI6X crushers are commonly used in the final stage of sand aggregate production to produce high-quality sand and aggregate with a uniform shape and size. They are ideal for producing sand for concrete and asphalt production. VSI6X crushers work by throwing the material against a hard surface, causing it to break into smaller pieces. The resulting material is then screened to remove any unwanted particles. VSI6X crushers are available in both stationary and portable configurations.
Screening Equipment:
Screening equipment is used to separate the sand and aggregate into different sizes and shapes. The most commonly used types of screening equipment are inclined screens, horizontal screens, and rotary screens. Inclined screens are used to separate the material into different sizes, while horizontal screens are used to separate the material into different shapes. Rotary screens are used to separate the material into different sizes and shapes simultaneously.
In conclusion, the selection of crushing equipment in sand aggregate production depends on various factors, including the type of material being crushed, the required size and shape of the final product, and the production capacity. Jaw crushers, impact crushers, cone crushers, and VSI6X crushers are the most commonly used types of crushing equipment in sand aggregate production. Screening equipment is also an essential component of sand aggregate production, as it is used to separate the material into different sizes and shapes.
