How can a horizontal crusher “flexibly adjust” to address fluctuations in fertilizer raw materials?

Written by fertilizer production line on October 14th, 2025. Leave a comment

Raw material fluctuations are common in fertilizer production. For example, the raw material for organic fertilizer may switch from “dry straw” to “wet bacterial residue,” or the raw material for compound fertilizer may change from “phosphate rock powder” to “potassium sulfate granules.” These fluctuations in raw material hardness, moisture content, and viscosity can lead to decreased pulverization efficiency and substandard particle size if the horizontal crusher cannot flexibly adjust.

Speed Adjustment to Adapt to Hardness Changes

When switching from “soft fibrous materials” (such as dry straw, which has low hardness) to “hard mineral materials” (such as phosphate rock, which has high hardness), the variable frequency motor can adjust the impeller speed to avoid excessive pulverization and dust generation. For hard materials, high speeds enhance impact and shear forces, ensuring effective pulverization. This allows adaptation to different hardness levels without changing equipment.

Gap Adjustment to Address Viscosity Differences

When processing high-viscosity raw materials (such as wet mushroom residue with a moisture content of 28%), a small gap between the impeller and the chamber wall can easily cause the material to stick to the wall. When processing low-viscosity raw materials (such as dry cake), a large gap will reduce grinding efficiency. A horizontal crusher can adapt to different viscosities, reducing sticking and ineffective grinding.

Screen Replacement to Adapt to Particle Size Requirements

Different fertilizer products require different particle sizes (organic-inorganic compound fertilizers require 3-5mm, powdered fertilizers require 0.8-1.2mm), and fluctuations in raw material quality may make the original screen size unsuitable. A horizontal crusher can quickly change screens with different apertures (commonly 0.5-10mm), flexibly meeting the particle size requirements of different raw materials and products.

Daily maintenance of horizontal crushers in the fertilizer industry

Written by fertilizer production line on October 14th, 2025. Leave a comment

As the core power equipment of a fertilizer production line, a horizontal crusher requires adequate daily maintenance, which directly impacts its operating efficiency and service life.

Regular Inspection of Core Components

Stop the horizontal crusher weekly to inspect the condition of the impellers. If the wear-resistant teeth at the end of the impellers are worn more than 1mm or cracked, they should be replaced promptly. Check the main shaft bearings monthly by touching the bearing seat. If the temperature exceeds 60°C or there is any abnormal noise, disassemble and clean the bearings and refill with high-temperature resistant grease. Check the grinding chamber liner quarterly. If the liner is severely worn or dented, replace it to ensure a tight seal.

Thorough Cleaning

After each production run, the pulverizing chamber must be cleaned of any residual material (especially after handling high-moisture materials). Compressed air or a special scraper can be used to prevent material agglomeration and corrosion of the chamber walls and impellers. The horizontal crusher casing and motor cooling holes should be cleaned monthly to prevent dust accumulation that could affect motor heat dissipation and cause overload and burnout. Quarterly, the seals at the feed and discharge ports should be inspected. If any seals are aged or deformed, they should be replaced promptly to minimize dust leakage.

Standardized Operations to Reduce Losses

Adjust the feed rate strictly according to the characteristics of the raw materials to avoid overloading. If the raw materials to be pulverized need to be changed (for example, from fibrous to hard materials), the residual material in the chamber must be cleared before adjusting the impeller speed and screen. Spare parts should be kept on hand to avoid prolonged downtime due to a shortage of parts in the event of a malfunction.

How to choose the right raw materials to optimize the production effect of organic fertilizer products ?

Written by fertilizer production line on October 14th, 2025. Leave a comment

Organic fertilizer is an important fertilizer source in modern agricultural production, and its production effect is directly related to soil fertility and crop yield. Selecting the right raw materials and optimizing the production process is the key to improving the quality of organic fertilizer.

First of all, the raw material selection of organic fertilizer should be based on the organic matter content, nutrient composition and microbial activity of the raw material. Common high-quality raw materials include animal manure, municipal sludge, domestic waste, sugar filter mud, wine lees, bean residue, straw, etc. After proper treatment and fermentation, these raw materials can be converted into nutrient-rich organic fertilizers.

In an organic Fertilizer Production Line, the Fertilizer Granulating Production Line is a key link in the formation of granular fertilizer. The granulation process not only improves the physical properties of fertilizer, but also helps to improve the application efficiency of fertilizer. For example, Fertilizer Granules Compaction Machine and Flat-Die Pellet Machine are commonly used granulation machines, which make raw materials into particles by extrusion, and these particles have good forming effect and high strength.

In order to further improve the quality of organic fertilizer, Windrow Compost Turning Machine plays an important role in the fermentation process. This equipment improves the fermentation efficiency by turning the compost, improving the ventilation conditions and promoting the rapid decomposition of organic materials.

In the production of organic fertilizers, the use of fertilizer shredders (such as Cage Crusher) is also essential. The pulverizer crushes the bulk organic material into the right size to facilitate subsequent mixing and granulation processes.

Finally, in order to ensure the uniformity of organic fertilizers and improve production efficiency, fertilizer mixers (such as the Horizontal Ribbon Mixer) and fertilizer Screening machines (such as the Rotary Screening Machine) are also indispensable equipment on the production line. Mixers are used for uniform mixing of raw materials, while sifters are used to separate fertilizer particles of different sizes to ensure consistency and quality of the final product.
Through scientific and reasonable raw material selection and production process optimization, it can not only improve the quality of organic fertilizer, but also contribute to the sustainable development of agriculture.

Horizontal crusher: How to ensure continuous operation of organic fertilizer production lines?

Written by fertilizer production line on October 14th, 2025. Leave a comment

In fertilizer production, production line interruptions are one of the most troublesome issues for companies. Frequent downtime of the pulverizing equipment causes delays in upstream and downstream processes (such as raw material pretreatment and subsequent granulation), directly reducing daily production capacity. However, the horizontal crusher, with its targeted design, serves as a “stabilizer” for ensuring continuous production line operation. Its core advantages are concentrated in three aspects.

1. Anti-clogging Design Reduces Downtime for Cleaning

To address the problem of caking and clogging of fertilizer raw materials (especially high-humidity fermented materials and fibrous materials), high-quality horizontal crushers feature a “tilted discharge chamber + self-cleaning impeller” structure. The tilted chamber accelerates material discharge and prevents accumulation. Elastic scrapers at the end of the impellers scrape residual material off the chamber walls as they rotate, eliminating the need for frequent downtime for cleaning.

2. Feeding and Production Line Compatibility

It can be used with automatic feeding devices (such as belt conveyors and screw feeders). Frequency conversion controls the feed speed to match the raw material conveying and pelletizing process, preventing “overfeeding and machine blockage” or “overfeeding and idling.”

3. Durability Reduces Failure Frequency

To address the abrasive nature of fertilizer raw materials (such as minerals), the chamber wall is constructed of a wear-resistant alloy, extending its average service life by two times that of ordinary materials. The device also features an overload protection device. If the chamber is overloaded, the motor automatically shuts off, preventing extended downtime due to component damage. This design ensures “less downtime, more operation” for the organic fertilizer production line.

Why do fertilizer crushers require special adaptations for bio-fertilizer production?

Written by fertilizer production line on October 13th, 2025. Leave a comment

The core difference between bio-fertilizer production and conventional organic fertilizer and compound fertilizer production lies in the need to preserve the activity of the inoculant. Furthermore, the raw materials often consist of specialized materials such as fungus residue, traditional Chinese medicine residue, and fermented straw. This places special demands on grinding equipment: low temperature, pollution prevention, and precise particle size. Through targeted modifications, fertilizer crushers have become the ideal choice for bio-fertilizer production.

1. Low-temperature crushing preserves inoculant activity

The functional bacteria in bio-fertilizer (such as Bacillus subtilis and phosphate-solubilizing bacteria) are not tolerant to high temperatures. Excessive frictional heat (above 45℃) generated during the grinding process can inactivate the bacteria. High-quality fertilizer crushers optimize the impeller speed (to avoid excessive friction) and some are equipped with a “water-cooling jacket” to circulate cold water to remove heat from the chamber walls, maximizing inoculant activity.

2. Anti-residue design prevents cross-contamination

Bio-fertilizer production often requires switching between different inoculant formulations. If residual material from previous batches remains in the equipment, bacterial strains can mix. The fertilizer crusher‘s “fully open cleaning structure” solves this problem. The grinding chamber door can be fully opened, and the smooth, corner-free interior allows for quick cleaning without disassembling core components, reducing the risk of cross-contamination.

3. Precise Particle Size for Microbial Agent Mixing

Bio-fertilizer production requires uniform particle size (typically 1-3mm) after grinding. Uneven particle size results in incomplete mixing of the microbial agent and raw material, impacting fertilizer efficiency. The horizontal crusher can precisely control particle size deviation within ±0.5mm, providing a high-quality raw material foundation for subsequent microbial agent inoculation and mixing.

Chain crusher: Suitable for processing a variety of fertilizer raw materials

Written by fertilizer production line on October 13th, 2025. Leave a comment

In the fertilizer industry, raw materials used for different fertilizer types vary significantly. Organic fertilizers require the processing of straw and fermented livestock and poultry manure, while compound fertilizers often involve hard particles such as phosphate rock and potassium chloride. Chain crushers, with their versatile adaptability, can easily handle the crushing needs of these diverse raw materials.

For fibrous raw materials such as straw and rice husks, common in organic fertilizer production, the chain of a chain crusher uses high-speed impact to sever the fibers, eliminating the “fiber entanglement” problem common in traditional hammer mills. The resulting pulverized material is loose and easy to mix with other raw materials for fermentation. For cake-based raw materials (such as soybean meal and rapeseed meal), the chain’s shear force effectively breaks up lumps and produces uniform crushed particles, eliminating excess powder and reducing raw material waste.

Even for hard mineral raw materials used in compound fertilizer production, chain crushers with high-strength alloy chains can achieve crushing through continuous impact, and the equipment’s lining is made of wear-resistant material, extending its service life.

In addition, it has a higher tolerance for the moisture content of raw materials. Wet materials with a moisture content of about 20% can be directly crushed without additional drying, which greatly simplifies the organic fertilizer production process and reduces the company’s initial investment.
