Why do people have this question? Granite is a very common type of rock distributed quite widely and many countries in the world produce granite. China’s 9% of the land (about 800,000 square kilometers) is granite. If it can be processed reasonably, it will be of great use to people’s production and life. However, granite is a kind of material which is hard to be crushed because of its high hardness and abrasion resistance. So here comes the question: is the hammer crusher appropriate for granite crushing?
The scope of application of hammer crusher is all kinds of ore with compressive strength not exceeding 100 MPa and water content less than 15%. Its production capacity is 5-3000t/h with feeding size less than 350 mm. Although granite has high hardness, it has a certain brittleness. The hammer mill can be used as the primary crushing equipment for granite crushing with large crushing ratio. The high-speed hitting of the hammer can crush the granite with very good sand making effects. The broken of large bulk of granite has positive effects with the discharge granularity below 35 mm. It can also be used for medium and fine crushing and the process of coarse crushing of jaw crusher is omitted. There is no need of primary or secondary crushing and it can be directly fed by vibrating feeder. It has the effect of “shaping by one hammer” with small and uniform discharge particle size. Granular granite aggregates with uniform grain size can be processed.

The discharging size of the hammer crusher can be controlled. By adjusting the grate to control the discharge specification of the stone, the user can screen the stone according to his actual needs. The yield will be affected by factors such as feeding hardness, crushing ratio, feed size and so on. If the uniform feed size is maintained, the smaller the stone size, the higher the yield. The following is the specifications and parameters of the hammer rock crusher:
Specification | Feeding Size (mm) |
Discharging Size (mm) |
Capacity (m³/h) |
Motor Power (kw) |
PCΦ400×300 | ≤100 | 10 | 5-10 | 11 |
PCΦ600×400 | ≤220 | 15 | 10-22 | 22 |
PCΦ800×600 | ≤250 | 15 | 18-40 | 55 |
PCΦ1000×800 | ≤350 | 13 | 25-50 | 75 |
PCΦ1000×1000 | ≤350 | 25 | 30-55 | 90 |
PCΦ1400×1400 | ≤350 | 35 | 50-100 | 280 |
Granite, one of the most common types of crushed stone, has a uniform structure, hard texture and durability. It is a high-quality construction stone, known as the “king of rocks”. Granite is extensively used as concrete and asphalt aggregate, a base material for highways, rural roads and buildings. Granite is not easy to be weathered, beautiful in color and its appearance can be kept for more than 100 years so it can be used as an ideal landscaping stone and architectural decoration. Different sizes of granite have different uses.
• Asphalt and Concrete
• Agricultural-lime (Ag-lime)
• Skid resistance on ice or snow
• Backfill and bedding materials
• Stabilized earth or reinforced soils
• Roof and floor of the hall
• Architectural ornament
• Outdoor sculpture

The main uses include pavement and architectural applications.
• Foundation for asphalt pavement
• Foundation for concrete pads and pavements
• Unpaved roads and shoulders
• Backfill for pipe and underground utilities
• Cement-treated base
foundation for pavement of 10-25 mm granites
It can be used for highway and railway industries.
• Concrete aggregate
• Asphalt aggregate
• Drainage stone
• Seal coat chips for roadways
• Stone roads and driveways
• Road base
• Backfill
