The small hammer crusher, also known as a sand making machine, is a compact and efficient ore crushing solution designed for small-scale mining operations and material processing plants. It is widely used to crush a variety of rocks, ores, and construction debris into uniform sand and gravel. This mini stone crusher is easy to install and operate, requiring low investment with fast return.
With its simple structure and high working efficiency, the mini hammer crusher adopts high-speed rotary hammers to impact and crush materials. It can replace traditional ball mills for specific beneficiation processes, especially in remote or resource-limited sites. Users can change the output size by selecting screens with different mesh sizes, the minimum discharge size reaching 2mm.
| Model | Capacity (t/h) | Feeding Size (mm) | Output Size (mm) | Motor Power (kW) | Diesel Engine (hp) |
|---|---|---|---|---|---|
| 200×500 | 1–2 | ≤50 | ≥1.5 | 5.5–7.5 | 24 |
| 300×500 | 3–6 | ≤50 | ≥1.5 | 11–18.5 | 30 |
| 400×600 | 5–10 | ≤50 | ≥1.5 | 22–30 | 45 |
| 600×800 | 10–15 | ≤50 | ≥1.5 | 30–45 | 75 |

The small hammer crusher for sand making is used to produce fine sand from various raw materials such as limestone, granite, and concrete waste. This construction-grade sand is suitable for concrete mixing, mortar preparation, and high-rise building foundations. The machine also plays a key role in recycled aggregate production, crushing discarded concrete and bricks into reusable sand, helping solve urban waste disposal challenges while promoting environmental sustainability.
In road and railway construction, the mini sand crusher creates base-level gravel for highways and produces high-strength ballast for railways. The sand and gravel it generates are well-graded and stable, improving roadbed support and railway track reliability. Especially in mountainous or remote areas, locally sourced rocks can be transformed into usable materials onsite, reducing transportation costs significantly.
For dams, embankments, and riverbank reinforcement, the hammer sand crusher produces different grades of construction sand for concrete casting. It can also process river stones and pebbles for use in ecological river remediation projects, helping strengthen flood defenses while enhancing environmental restoration efforts.
The small hammer crusher for ore processing is frequently used to crush raw materials into fine particles, ideal for pre-chemical reactions. For example, in fertilizer production or chemical metallurgy, it prepares mineral inputs to the desired grain size, increasing reaction efficiency and improving final product consistency.
