Tongli Chain Crusher

Tongli chain crusher is a new type of crusher, which is a special crushing equipment for fertilizers. It effectively solves the problem that fertilizers cannot be crushed due to moisture absorption in the production of fertilizer industry. The machine has the advantages of easy use, high efficiency, large production capacity and simple maintenance. It is suitable for crushing various block fertilizers and other medium hardness materials. It can also crush undried calcium phosphate fertilizers with 14% water content and 6% free acid. It overcomes the shortcomings of many chain crushers and other crushers used in phosphate fertilizer production that the materials are adhered to the inner wall of the casing during operation, making the crushing operation continuous. The high-efficiency chain crusher is an indispensable advanced crushing equipment in the current production of nitrogen fertilizers, phosphate fertilizers and compound fertilizers, and its processing capacity is most suitable for nitrogen and phosphorus compound fertilizer production plants.

FAQ

1. What is the role of a chain crusher in compound fertilizer production?

The chain crusher plays a key role in the production of compound fertilizers, primarily used for crushing raw materials and intermediate products to ensure particle uniformity and size compliance. In compound fertilizer production, uniform particles are essential for the even release and absorption of nutrients.

The chain crusher crushes materials through high-speed rotating chains, typically controlling the particle size between 0.5mm and 5mm. This efficient crushing method not only improves product quality but also enhances the market competitiveness of the fertilizer.

Additionally, the chain crusher can handle a variety of raw materials, including urea and ammonium phosphate, making it highly adaptable and indispensable in compound fertilizer production lines.

2.What is a chain crusher, and why is it needed in compound fertilizer production?

A chain crusher is a widely used crushing device, mainly for breaking medium-hard and high-moisture materials. In compound fertilizer production, raw materials like urea, potassium salts, and phosphates usually come in large chunks or lumps. These materials need to be pre-treated into smaller particles to facilitate subsequent mixing and granulation processes.

The chain crusher breaks down large materials into smaller particles through high-speed rotating chains, ensuring material uniformity, improving the quality of the compound fertilizer, and boosting production efficiency.

Additionally, its self-cleaning function effectively prevents clogging from high-moisture materials, making it an essential piece of equipment in the fertilizer production process.

3. Is the chain crusher suitable for all types of compound fertilizer production?

Yes, the chain crusher is suitable for various types of compound fertilizer production, including nitrogen, phosphorus, and potassium (NPK) fertilizers, organic fertilizers, inorganic fertilizers, and bio-fertilizers. Its flexible design and efficient crushing capability allow it to handle a wide range of materials, meeting the demands of different types of fertilizer production.

This enhances the adaptability and flexibility of production lines. Furthermore, the machine’s high efficiency and reliability ensure stable operation in diverse production environments, adapting to market demands.

Its multifunctionality makes the chain crusher an indispensable piece of equipment in fertilizer production, significantly improving overall production line efficiency.

4. How is particle size controlled in a chain crusher during compound fertilizer production?

The chain crusher can precisely control the particle size, typically crushing materials to a range of 2 to 5 millimeters. By adjusting the chain tension and chain speed, the particle size can be flexibly modified according to production requirements, ensuring that the final product meets quality standards.

This high-precision control helps improve the uniformity and quality of the compound fertilizer, meeting the market demand for high-quality products.

In addition, accurate particle size control also facilitates subsequent processing steps, improving overall production efficiency. This capability makes the chain crusher essential in compound fertilizer production.

5. How does the chain crusher handle high-moisture materials in compound fertilizer?

High-moisture materials are common in compound fertilizer production, and the chain crusher’s self-cleaning function and special chain design effectively prevent material sticking and clogging during the crushing process.

The unique chain design and arrangement of the crushing teeth ensure smooth material flow within the crushing chamber, reducing the likelihood of materials adhering to the equipment’s interior.

Additionally, the machine is equipped with an automatic cleaning system to regularly remove residual materials, ensuring stable operation in high-moisture environments. This significantly reduces downtime due to clogging and improves production efficiency.

6. How does the chain crusher ensure long-term durability and reduce maintenance costs?

The chain crusher is designed with durability in mind, featuring high-strength materials for key components such as the chains and crushing teeth. These components are typically made from wear-resistant alloys, which can withstand the abrasive nature of the materials being processed. This robust construction helps extend the machine's lifespan, reducing the frequency of repairs and replacements.

Regular maintenance is essential to prolong the crusher's durability. The machine is equipped with easy-access inspection points, allowing for quick and efficient maintenance checks. Lubricating moving parts and periodically adjusting chain tension are simple maintenance tasks that help prevent excessive wear and tear, ensuring consistent performance.

Moreover, the self-cleaning mechanism minimizes material build-up, reducing the risk of blockages and downtime. This design not only ensures long-term durability but also lowers maintenance costs by preventing frequent interruptions, making the chain crusher a cost-effective solution for fertilizer production.
