Types of Aggregate Crusher in Kenya

In Kenya, the construction industry plays a crucial role in the country’s economic development, driving the demand for various construction materials, with aggregates being a key component. Aggregate crushers are specialized machines designed to break larger rocks into smaller, more manageable pieces for use in construction projects. These crushers are essential in the production of concrete, asphalt, and other construction materials. Let’s explore the types of aggregate crushers commonly used in Kenya.

Jaw Crushers:
Jaw crushers are primary crushers designed to break large, hard, and abrasive materials into smaller particles. They consist of a fixed jaw and a moving jaw, with the material being crushed between them. Jaw crushers are versatile and widely used in various applications, including quarrying and mining. In Kenya, they are commonly employed for primary crushing in aggregate production plants.

Cone Crushers:
Cone crushers are used for secondary and tertiary crushing. They operate by compressing the material between an eccentrically rotating mantle and a concave bowl liner. Cone crushers are known for their efficiency in producing well-shaped and finely graded aggregates. They find applications in both the mining and construction industries in Kenya, contributing to the production of high-quality aggregates.

Impact Crushers:
Impact crushers are versatile machines that can handle various types of materials, including soft, medium-hard, and hard rocks. They work by applying a high-speed impact force to the material, causing it to break along its natural cleavage lines. Impact crushers are suitable for both primary and secondary crushing and are commonly used in the production of railway ballast and concrete aggregates in Kenya.

Gyratory Crushers:
Gyratory crushers are primary crushers that are most commonly used in large-scale mining operations. They consist of a conical-shaped gyrating crushing head mounted on a spindle. Gyratory crushers provide high capacity with relatively simple maintenance requirements. While not as common as jaw or cone crushers, they are used in some specialized applications in Kenya’s mining sector.

Vertical Shaft Impact (VSI) Crushers:
VSI crushers are designed for tertiary and quaternary crushing stages. They use the principle of rock-on-rock crushing to reduce the size of the material by impacting it against a hard surface. VSI crushers are particularly effective in producing cubical-shaped aggregates and are often used in the production of manufactured sand for construction purposes.

The construction industry in Kenya relies heavily on the production of high-quality aggregates, and various types of crushers are employed to meet this demand. The choice of crusher depends on factors such as the type of material, desired product size, and production capacity.
