What equipment is used to crush large rocks

Different crushers have varying requirements for material particle size in crushing processes. For example, jaw crushers accept maximum feed sizes of 1.2 meters, impact crushers handle feed sizes under 50-60 centimeters, and sand makers process feed sizes below 5 centimeters. Materials exceeding a crusher's specified range must be prohibited to prevent equipment damage or personal injury. So, which crusher should be selected for processing large rock blocks? Here's the answer:

We recommend using large-capacity jaw crushers and heavy hammer crushers.

1. Jaw Crusher

The jaw crusher is a traditional primary crushing machine. It features a high crushing ratio and strong crushing force, with a feed opening size of 1500x1800mm and a maximum feed size of 1200mm. This means stones with diameters under 1.2 meters can be directly fed into the jaw crusher for processing. It is fully adequate for large rock crushing, with a compressive strength range of 147-245 MPa. Its processing capacity is robust, reaching 1-1000 t/h, with an output particle size of 10-350mm. The wedge-type discharge opening adjustment reduces labor intensity and downtime. The integrated motor base and main unit structure simplifies installation and saves space, making it an essential tool for rock crushing.

2. Heavy Hammer Crusher

The heavy hammer crusher features a feed opening (L×W) of 2530×1610mm, with an optimal feed size ≤1000mm and an output size achievable below 20mm. It processes various soft and brittle materials with compressive strengths below 200 MPa. While slightly less powerful than jaw crushers, it delivers uniform output particle sizes. It can crush large rocks into various sizes of crushed stone in a single pass, eliminating secondary processing steps and reducing overall costs by approximately 40%. As an energy-efficient, low-investment crushing solution, it is currently a popular choice among customers.
