Hammer Roller Crusher

Granular fertilizers and other large raw materials require effective crushing to streamline production processes, and the hammer roller crusher is an ideal solution for that task. Its design allows it to break down materials such as ammonium phosphate, NPK fertilizers, and urea into smaller, uniform pieces, improving the efficiency of subsequent stages like granulation or mixing. Equipped with a hydraulic cleaning system and long-lasting wear components, it features reliable, continuous operation with minimal downtime. Besides processing fertilizers, the versatility of this crusher makes it suitable for industries such as light manufacturing, building materials, and metallurgy, offering consistent performance for diverse applications.

FAQ

How to choose the right fertilizer production equipment for my plant?

Choosing the right equipment for your fertilizer production project starts with understanding your production needs. Here are a few key questions that help narrow down the best options:

What type of raw materials are you working with?
Do you aim to produce powdered or granular fertilizer? What specific characteristics should the final product have?
What is the desired output capacity for your production line?
What are the local environmental conditions, such as temperature and material moisture levels?
What heat source will your drying equipment rely on?

Once we have this information, we can recommend the most suitable fertilizer processing equipment and production line for your needs.

Why does the granular fertilizer produced by my production line tend to clump?

Clumping is a common issue in fertilizer production, usually caused by moisture, temperature, and pressure. If the fertilizer you are planning on producing has a high moisture content, it could lead to clumping, which might mean your drying equipment isn’t performing optimally. Similarly, high temperatures can make the granules more prone to sticking together, which is why cooling equipment is often used after the drying process. Lastly, high pressure in the fertilizer production line can increase the surface area of the granules, making them more susceptible to chemical reactions that cause clumping.

Working Principle

Hammer roller crushers operate using two horizontal shafts,one equipped with heavy hammers and the other with a roller. As materials are fed into the crusher, the hammers that are rapidly spinning break them down before the slower-moving roller further processes them. The resulting crushed material is discharged from the bottom for further production steps.
