How to set up a 350 tph granite crushing line with cone crusher

1. Understand Granite Characteristics and Stage Crushing Needs
Granite is a hard, abrasive igneous rock with high compressive strength (150-250 MPa). Setting up how to set up a 350 tph granite crushing line with cone crusher requires a multi-stage process because a single crusher cannot handle the reduction from run-of-quarry (up to 700mm) to final aggregate (0-5mm, 5-20mm, 20-40mm). The standard approach is a three-stage configuration: a jaw crusher for primary, a cone crusher for secondary, and sometimes a second cone for tertiary or a VSI for shaping. For 350 tph in Saudi Arabia or UAE, where granite is widely used for road base and concrete, you need durable equipment with high wear resistance. Actual performance depends on feed gradation, moisture, and work index. Always verify with material testing or consult OCP engineers.

2. Primary and Secondary Equipment Selection
To achieve how to set up a 350 tph granite crushing line with cone crusher, start with the primary jaw crusher. A Type J-120 (1,200×900mm feed opening) operating at 180-220 rpm can easily handle 350 tph of granite with a CSS of 150-180mm. The jaw’s output goes to a secondary cone crusher – this is where the cone plays its key role. For secondary crushing, choose a standard cavity cone (Type C-S) with a closed side setting (CSS) of 30-40mm. This will reduce the material to 0-80mm. For tertiary crushing (if you need fine aggregates), a short head cone (Type C-SH) with CSS 10-15mm is recommended. Some lines use a single large cone (Type C-440) in closed circuit with a screen to produce all final products. *Production data are based on typical granite (density 2.7 t/m³, work index 16-18).

3. Screening, Conveying and Stockpiling
A well-designed screening circuit is critical for how to set up a 350 tph granite crushing line with cone crusher. After secondary crushing, feed the material onto a double-deck vibrating screen (Type S-2460) with 40mm and 20mm apertures. Oversize (+40mm) returns to the secondary cone via a conveyor. The 20-40mm fraction goes to a finished stockpile. The 0-20mm fraction can either be sold or sent to a tertiary cone for further reduction to sand. Use belt conveyors with impact beds and skirtboards to prevent spillage at transfer points – crucial for dusty granite operations in the Middle East. OCP Mechanical Company offers pre-fabricated modular conveyor systems that reduce on-site civil work by up to 40%. Machine efficiency and cost-effectiveness are our design goals, but results depend on proper conveyor alignment and screen media selection.

4. Cone Crusher Settings and Automation for 350 tph
To consistently maintain 350 tph, the cone crusher must be choke fed with a steady material flow. Install a level sensor in the cone’s feed hopper to automatically adjust feeder speed. Set the secondary cone’s CSS to 32-36mm – tighter settings increase fines but reduce throughput; looser settings may fail to produce the desired product size. For the tertiary cone (if used), a CSS of 8-12mm with a fine cavity works well. OCP’s cone crushers feature hydraulic adjustment under load and tramp iron relief – allowing you to change settings in seconds without stopping production. Many of our clients in Riyadh and Dubai have achieved stable 350 tph for over 8,000 hours on a single set of manganese liners (Type M18). Wear life varies with abrasiveness; always monitor liner thickness weekly.
