In the field of organic fertilizer production, chain crushers have become the ultimate solution for processing high-moisture, easily agglomerated materials with their unique “soft-violence” crushing method, earning the reputation as the “wall-breaking expert of organic fertilizer production.”
Core Function: Breaking the “Molecular Barriers” of Organic Matter
The chain crusher uses high-speed rotating chains to impact, collide with, and shear materials, achieving three core functions:
- Physical wall-breaking: Destroys plant cell wall structures to release internal nutrients
- Homogenization: Decomposes lumpy materials to an ideal particle size of 3-5mm
- Pre-fermentation preparation: Increases material surface area to promote microbial activity
Main Applications and Suitable Scenarios
Chain crushers demonstrate unique value in the following scenarios:
- Livestock manure processing: Chicken/pig manure with 40-60% moisture content
- Straw materials: Fibrous materials like corn stalks and rice straw
- Food waste composting: Mixed organic waste containing plastic bag impurities
- Sludge composting: Coordinated treatment of municipal sludge and agricultural waste
Technical Features: The Intelligence of Gentle Crushing
- 3D crushing: Multi-angle chain movement creates a three-dimensional crushing space
- Self-cleaning design: Rotational centrifugal force automatically removes adhered materials
- High moisture tolerance: Can process materials with ≤65% moisture content
- Overload protection: Chains automatically yield when encountering hard objects
- Energy optimization: 15-20% more energy efficient than traditional hammer crushers
Outstanding Advantages
- Processes sticky/wet materials without clogging
- Excellent fibrous material crushing effect
- Low maintenance costs (easy chain replacement)
- Adapts to complex component raw materials
- Operation noise <85 decibels
Existing Limitations
- Lower efficiency with dry, hard materials
- Less precise fineness control compared to roller crushers
- Higher initial investment than ordinary hammer crushers
- Requires regular chain tension adjustment
- Not suitable for materials with high metal impurities
Innovative Applications: Beyond Traditional Crushing Concepts
Modern chain crushers have developed intelligent versions that can automatically adjust speed to accommodate materials with different moisture levels through installed moisture sensors and frequency conversion control systems. Some advanced models also integrate pre-mixing functions, achieving preliminary raw material mixing during crushing, increasing production efficiency by over 30%.
When selecting a chain crusher, it is recommended to focus on three key quality indicators: chain material (Mn steel alloy recommended), main shaft bearing type (at least 22200 series), and casing wear-resistant liner thickness (should not be less than 15mm) to ensure the equipment’s lasting stability under harsh working conditions.
Chain Crusher
The chain crusher can be divided into wo tvpes, verlical chain crusher and honzontal chaln crusher. the verical chaln crusher issingle rotor, and the horizontal chain crusher is double rotors. Vertical chain crusher is one of the most common crusher used in thecompound fertilizer industry. in the process of crushing, the machine uses a high strength and wear-resistant hard alloy chain withsynchronous rotaing speed. For prevent sticky material and machine body steel friction, a rubber lining is added to the machinewhich for materials is not easy to stick to the wall, and is easy to clean up; There are fast open maintenance doors on both sides omachine body to facilitate the maintenance, the machine body and transmission device are installed on the base of a structural steel.keeping the machine running smoothly and lengthening the service life of the machine. The machine is suitable for crushing rawmaterials and recycled materials, and it is also widely used in chemical industry, building materials, mining and other industries.
