Granite primary crushers in South Africa are essential for breaking down large blocks of granite extracted from quarries into manageable sizes for further processing. Here are some key aspects to consider regarding primary crushers for granite in South Africa:
1. Types of Primary Crushers for Granite
– Jaw Crushers: Commonly used as primary crushers due to their ability to handle large feed sizes and high compressive strength (granite is a hard rock). Examples include:
– Metso Nordberg C Series Jaw Crushers
– Sandvik CJ Series Jaw Crushers
– Terex Jaques Jaw Crushers
– Gyratory Crushers: Suitable for high-capacity crushing operations in large quarries.
– Impact Crushers (Primary): Sometimes used if the granite is less abrasive, but less common than jaw crushers.
2. Key Suppliers & Manufacturers in South Africa
– Metso Outotec – Offers robust jaw and gyratory crushers.
– Sandvik Rock Processing Solutions – Provides high-performance jaw crushers.
– Pilot Crushtec – A leading South African distributor of crushing equipment, including Terex Finlay and Terex Jaques crushers.
– Bell Equipment – Supplies Terex Finlay mobile jaw crushers.
– Astec Industries (Osborn) – Local manufacturer of jaw and cone crushers.
3. Factors Influencing Choice of Primary Crusher
– Feed Size & Capacity Requirements – Jaw crushers handle larger feed sizes (up to 1,500 mm).
– Hardness & Abrasiveness of Granite – Requires wear-resistant materials like manganese steel liners.
– Mobility Needs – Fixed vs. mobile primary crushers (track-mounted options available).
– Downstream Processing – Whether secondary crushing (cone/impact crusher) follows.
4. Popular Models in South Africa
– Metso C120 / C150 Jaw Crusher
– Sandvik CJ412 / CJ615 Jaw Crusher
