Can you Achieve Manufactured Sand (0–5mm) from Granite?

Yes. Granite is one of the most common materials for manufactured sand production. A VSI (vertical shaft impact) crusher in the third stage shapes the particles and produces a well-graded 0–5mm product that meets most concrete sand standards.

How Quickly do Wear Parts Wear out on Granite?

Faster than on most other materials. Jaw plate life on granite typically runs 300–600 operating hours depending on liner grade and feed size. We recommend keeping a spare set on site to avoid unplanned downtime. Our engineers can advise on the right liner specification for your specific granite source.

Which Crusher Type is Best for Granite Primary Crushing?

A jaw crusher is the standard choice for granite primary crushing. Its compressive crushing action suits the hardness, and the simple chamber geometry is easy to maintain in quarry conditions. For very high capacities above 800 t/h, a gyratory crusher may be considered.

Can the CSS be Adjusted While the Crusher is Running?

Standard PE jaw crushers use rear-wedge CSS adjustment, which requires the machine to be stopped and the eccentric shaft to be at rest before adjustment. Hydraulic CSS adjustment systems — available as an option — allow gap changes under load without stopping production, which is particularly valuable for operations processing variable feed material.

How Often do Jaw Plates Need to be Replaced?

Jaw plate life depends heavily on material hardness and abrasiveness. On limestone, expect 500–1,500 operating hours. On granite or basalt, 300–800 hours is typical. High-manganese (Mn18%) plates last longer on hard, abrasive feed. We supply OEM jaw plates for all PE models and recommend keeping one spare set on site to minimize downtime during a […]

Is a PE Jaw Crusher Suitable for Mobile Crushing Plants?

Yes — smaller PE models (PE400×600 through PE600×900) are commonly mounted on mobile chassis for primary crushing. For mobile applications where feed size is large and throughput requirements are high, the PE900 and above series are used on heavy wheeled or tracked carriers. European jaw crushers (C-series) are an alternative for hard-rock mobile applications where […]

What Causes a Jaw Crusher to Stall or Block?

The most common causes are: (1) feeding oversized material that exceeds the rated maximum feed size; (2) surge-loading — dumping a full truck directly into the crusher without a feeder to regulate feed rate; (3) wet, sticky material bridging at the feed opening; and (4) uncrushable objects (metal) triggering toggle plate fracture. A vibrating feeder […]

What is the Difference Between the Fixed Jaw and the Swing Jaw?

The fixed jaw is bolted rigidly to the crusher frame and does not move. The swing jaw is mounted on a pitman arm and moves in an elliptical path driven by the eccentric shaft — forward to compress material, backward to release crushed product. Both jaws carry replaceable manganese steel jaw plates that take the […]
