The Fine Crusher produced by Zhengzhou Zhenggang Machinery Co., Ltd. is a high-efficiency impact fine crusher designed for sand-making and fine crushing production lines. It adopts a large arc-shaped crushing chamber and uses the “stone-on-stone” self-impact crushing principle to achieve large feed size, fine discharge size, high production capacity, and excellent finished grain shape. The machine is suitable for materials with compressive strength not exceeding 200 MPa, including limestone, marl, sandstone, shale, gypsum, coal, and similar medium-hard materials. With simplified two-stage crushing, high-chromium hammer plates, special impact liners, easy maintenance access, long hammer life, and low operating cost, the Fine Crusher is widely used in highways, railways, water conservancy, construction, metallurgy, and sand-making production lines.
The large arc-shaped crushing chamber and continuous impact crushing process support high output and efficient fine crushing performance.
The machine can simplify the crushing process by replacing traditional three-stage crushing with two-stage crushing, reducing equipment investment and energy use.
High-chromium hammer plates and wear-resistant liner design improve hammer durability and reduce replacement frequency.
The finished product has a cubic shape with low needle and flake content, making it suitable for high-standard construction aggregates.
The discharge size can be adjusted according to production requirements, supporting flexible sand-making and fine crushing applications.
Energy-saving design, simplified structure, easy maintenance, and reduced wear-part consumption help lower overall crushing cost.
Used for producing fine sand and cubic aggregates in manufactured sand production systems.
Suitable for fine crushing limestone for construction materials, cement raw materials, and aggregate production.
Applied for crushing shale, sandstone, marl, and similar medium-hard materials into smaller particle sizes.
Used for fine crushing coal, gypsum, and other industrial materials in building materials and metallurgy industries.
Suitable for producing high-quality stone materials for highways, railways, water conservancy, and construction projects.
Suitable for fine crushing limestone, gypsum, sandstone, shale, and coal in cement plants, building material factories, and sand-making production lines.
