Tongli Double cage crusher

Tongli double cage crusher is a medium-sized horizontal cage crusher. It is designed based on the impact crushing principle. The inner and outer cages rotate at high speeds in opposite directions. The material is crushed from the inside to the outside by the impact of the cages. The fineness of the crushing is controlled by the distance between the two rollers. The smaller the distance, the finer the fineness, and the lower the output. The more uniform the material addition, the better the crushing effect, and the higher the output. This equipment can be designed to be mobile according to user requirements. Users can move it to the corresponding position when using it and move it away when not in use. It is very convenient.

A MACHINE YOU CAN DEPEND ON!

Tongli double cage crusher is based on the principle of impact crushing. The two groups of cage bars inside and outside rotate in opposite directions at high speed. The materials are crushed from the inside to the outside by the impact of the cage bars. It has high crushing efficiency, simple structure, high crushing efficiency and good sealing performance, and stable operation. For materials with high water content, the use of a two-stage non-screen bottom crusher can avoid the blockage problem caused by high material humidity and improve the crushing efficiency.

Double cage synchronous rotation design

The equipment uses high-strength hard alloy cage bars with synchronous speed during the crushing process. The inlet and outlet are reasonably designed, the crushed materials are uniform, not easy to stick to the wall, and easy to clean.



Rotor spindle optimization

The rotor spindle is supported on two bearing seats through self-aligning bearings, and a chain seat is installed on the spindle. The chain seat is used to install the ring chain, and the chain seat can protect the spindle from corrosion and damage.

Wet material processing capacity:

Through the unique design, the double cage crusher can handle materials with a humidity of up to 20%, solve the problem of high-humidity material crushing, expand its application range, and is suitable for industries with more wet materials.

FAQ

1. What is a double-cage crusher, and what is its role in fertilizer production?

The double-cage crusher is a high-efficiency crushing device primarily used for material breaking and refining, playing an important role in fertilizer production. Its dual-rotor design significantly enhances crushing efficiency, reaching up to 95%.

In fertilizer production, it is particularly suitable for handling large raw materials such as urea and ammonium phosphate, breaking them down into the appropriate particle size for subsequent mixing and granulation. This equipment can crush materials larger than 10 mm into particles ranging from 0.5 to 3 mm, ensuring the required particle size for various fertilizers.

In addition to improving production speed, the double-cage crusher reduces energy consumption, which lowers production costs, making it an indispensable piece of equipment in modern fertilizer production lines.

2.How is the output particle size of the double-cage crusher adjusted?

Adjusting the output particle size of the double-cage crusher is a key factor based on production needs. The device can achieve flexible particle size adjustment between 0.5 and 3 mm by regulating the rotor speed and feed rate. Specifically, the faster the rotor speed, the more pronounced the crushing effect, while controlling the feed rate helps prevent overloading.

This adjustment mechanism allows companies to precisely meet the particle size requirements for various fertilizer products, improving the final product quality and market competitiveness. In practice, operators can adjust the machine according to the raw material characteristics and product demands to achieve the desired crushing effect.

It is important to regularly monitor the output particle size and adjust the settings based on production changes to ensure continuous and stable production efficiency, meeting the diverse market demands for fertilizer products.

3. What types of fertilizers can the double-cage crusher handle?

The double-cage crusher has a wide range of applications and can efficiently handle various types of fertilizer raw materials, including nitrogen fertilizers (such as urea and ammonium nitrate), phosphate fertilizers (such as ammonium phosphate and superphosphate), and potassium fertilizers (such as potassium chloride).

Due to the flexible design of the device, it can accommodate the physical characteristics of different fertilizer types, ensuring that large raw materials are crushed into the required particle sizes. It is particularly effective in processing sticky, high-hardness materials. The crusher's efficiency ensures smoother processing during the crushing phase of fertilizer production, enhancing overall production efficiency and reducing production time.

Additionally, the diversity of market demand requires manufacturers to constantly adjust product types, and the versatility of the double-cage crusher allows it to quickly adapt to different production needs, thereby reducing the costs associated with raw material handling. By selecting the right equipment, companies can not only increase production but also improve their product's market competitiveness.

4. How is the double-cage crusher positioned in the fertilizer production line?

In a fertilizer production line, the double-cage crusher is usually positioned between the raw material processing and mixing stages. Before entering the crusher, the raw material undergoes preliminary screening to ensure that the particle size is appropriate for the crushing phase.

The materials are transported to the crusher via a conveyor belt, and after being processed by the two rotors, they are reduced to the required particle size. The crushed materials are then sent to the mixing stage via another conveyor belt. A well-planned production line layout can not only improve material transfer efficiency but also reduce waiting times between stages, thus boosting overall production efficiency.

Based on experience, a good layout can shorten the production cycle by over 15%. Additionally, companies should consider maintaining safety distances between equipment during layout planning to ensure sufficient workspace for operators, minimizing safety risks. In summary, the proper positioning of the double-cage crusher in a fertilizer production line is critical to improving production efficiency and ensuring operational safety.

5. What is compound fertilizer, and what is the role of the double-cage crusher in its production?

Compound fertilizer is a type of fertilizer that contains two or more nutrients, such as nitrogen, phosphorus, and potassium, to provide balanced nutrition for plants.

Compared to single-nutrient fertilizers, compound fertilizers offer a more rational nutrient composition, effectively increasing crop yields and quality. The double-cage crusher plays a crucial role in the production of compound fertilizers. This device crushes raw materials such as nitrogen, phosphate, and potassium fertilizers into the required particle size for subsequent mixing and granulation.

By efficiently breaking down large raw materials, the double-cage crusher ensures material uniformity, thereby guaranteeing the quality of the final product. Additionally, the crushed materials exhibit better particle size and flow properties for further processing, which not only enhances production efficiency but also reduces energy consumption, providing significant economic benefits to the company.

6. What are the key advantages of using a double-cage crusher in fertilizer production?

The double-cage crusher offers multiple advantages that enhance fertilizer production. First, it provides efficient crushing of large raw materials such as urea, ammonium phosphate, and potassium salts, reducing them to the ideal particle size for further processing. The machine’s high crushing rate, reaching up to 95%, ensures that raw materials are processed effectively, significantly improving production efficiency.

Another key benefit is the ability to control the output size of particles, which can be adjusted to 0.5 to 3 mm based on production needs. This adaptability allows manufacturers to meet the specific demands of different fertilizer types, ensuring a consistent product quality. The machine’s energy efficiency also reduces operational costs, making it an economical choice for fertilizer production lines.

Moreover, the double-cage crusher is versatile and can handle a variety of raw materials, including both dry and wet substances. Its self-cleaning function prevents clogging, even with sticky materials, ensuring smooth, continuous operation. This adaptability and reliability make the crusher an essential part of modern fertilizer manufacturing processes.
