High-efficiency fine crusher

The fine crusher is a novel sand production equipment developed in accordance with national manufactured sand standards, user requirements, and industry knowledge of sand and gravel. It is suitable for customers seeking low investment and short-term high-efficiency returns. Primarily applicable to the artificial sand production industry and rock crushing with low hardness requirements, the fine crusher can also be utilized for secondary crushing operations in mining and chemical industries.The equipment features small finished particle size, low dust emission, uniform particle distribution, high production capacity, long hammer head service life, low energy consumption, simplification of three-stage crushing to two-stage crushing, simple structure, stable operation, and convenient maintenance.

Discharge particle size: ≤5 mm

Motor power:45-315kw

Product Introduction

Working Principle

1. Materials enter the crushing chamber from the feed inlet and fall onto the blow bars of the high-speed rotating rotor, where they are initially crushed by impact, shearing and grinding.

2. The crushed materials are thrown onto the impact liner for secondary impact crushing; unqualified materials are circulated and crushed repeatedly in the chamber.

3. Qualified fine materials are discharged through the grate bars/sieve plates to complete fine crushing/sand making; some models are equipped with double chambers to enhance the fine crushing effect.

Advantages

1. High crushing efficiency and large output with a large crushing ratio. It can crush large materials into fine materials in one go, simplifying the process and saving equipment.

2. Excellent discharge particle shape, suitable for manufactured sand. Most finished products are cubic with few needle-like and flaky particles and good gradation, which can be directly used in commercial concrete production, road construction and building construction.

3. Low energy consumption and operating cost. Reasonable structure, mainly impact crushing, saving electricity compared with traditional hammer crushers and reducing wear of wear-resistant parts.

4. Adjustable discharge particle size. By adjusting the clearance and grate bars, the fineness can be flexibly controlled to meet different sand usage requirements.

5. Compact structure and small footprint. Integrated design, easy installation, suitable for sites with limited space.

6. Easy maintenance and convenient overhaul. Quick replacement of wearing parts, low failure rate and short downtime.

7. Wide application range. It can crush limestone, river pebbles, granite, coal gangue, slag, ore and other materials.

8. Less dust and relatively low noise. Good sealing performance, more in line with environmental protection requirements.

Application

Applicable materials: Medium-hard and hard-brittle materials with a compressive strength ≤ 200 MPa, such as limestone, granite, river pebbles, basalt, cement clinker, quartz sand, iron ore, bauxite, coal gangue, slag, etc.

Applicable scenarios: Manufactured sand, construction aggregates, construction of high-grade highways, railways, water conservancy projects and airports, cement production, refractory materials, metallurgy, chemical engineering, mine fine crushing, etc.
