The double-roller press granulator is a core piece of equipment for forming powdered materials in fertilizer production line s, chemical industries, and other sectors.  It is widely used due to its high efficiency, energy saving, and high granulation rate. Standardized operation not only ensures stable granule quality and extends equipment service life but also prevents safety accidents and improves production efficiency. Based on practical production experience, its operating essentials can be divided into three main stages: pre-startup preparation, in-operation control, and post-shutdown maintenance, each requiring meticulous attention. Pre-startup preparation is the foundation for safe and efficient operation. First, check the overall condition of the equipment, calibrate the machine body with a spirit level to ensure that the axes of the double rollers are on the same horizontal plane, and tighten the anchor bolts and connecting bolts of each component to prevent vibration and...

Bio-organic fertilizer is made from raw materials such as livestock and poultry manure and crop straw, after microbial fermentation and maturation. It has the dual functions of fertilizing the soil and improving crop quality. Its standardized production relies on the coordinated operation of a complete set of equipment. A complete bio-organic fertilizer production line can be divided into four major modules according to the process flow: pretreatment, fermentation, deep processing, and finished product handling. Each piece of equipment performs its specific function, ensuring efficient production and product quality. Pretreatment equipment is the foundation of production, and its core components include crushing equipment, mixing equipment, and screening equipment. Crushing equipment breaks down raw materials such as straw and dead branches to a suitable particle size, facilitating microbial decomposition; mixing equipment accurately proportions raw materials, microbial inoculants, an...

Bio organic fertilizer equipment is susceptible to problems such as adhesion, wear, and clogging due to high humidity and the characteristics of the materials containing microbial agents. Scientific maintenance not only extends the equipment's lifespan but also ensures the production efficiency and microbial activity of the bio organic fertilizer production line , reducing operating costs. Maintenance should follow the principles of "cleaning first, lubrication second, regular inspection, and protection as needed," combining daily operation and periodic maintenance to accurately avoid potential malfunctions. Daily maintenance is fundamental and should be carried out throughout the entire bio organic fertilizer production process . Before starting the machine, clean impurities from the feed inlet, check the smooth operation of the spray humidification system, and verify that the lubricating oil level in the bearing box meets the standard, ensuring that there is no damage ...

Caking is a common problem in the production and storage of bio-organic fertilizers.  It not only affects the product's appearance and ease of application but can also damage the activity of beneficial microorganisms and reduce fertilizer efficiency. Its causes are closely related to raw material characteristics, production processes, and storage conditions. Effective control requires comprehensive management throughout the entire bio-organic fertilizer production process , combining scientific methods to ensure both product quality and application performance. Raw material pretreatment is fundamental to preventing caking. Livestock manure, straw, and other raw materials should be sorted and crushed to remove large, non-degradable impurities. Straw and other coarse fiber materials should be crushed to 3-5 centimeters to ensure uniform particle size and reduce caking caused by uneven stacking gaps. Simultaneously, precisely adjust the moisture content and carbon-to-nitrogen ratio. C...

The double-roller press granulator is a core piece of equipment for granulation in fertilizer production line s and chemical industries. Its stable operation directly determines production efficiency and product quality. Scientific maintenance can reduce component wear, avoid malfunctions, and extend the equipment's service life, which is crucial for ensuring continuous production. Based on the equipment's operating characteristics, the following summarizes comprehensive and practical maintenance points. Daily cleaning is fundamental to maintenance and should be carried out throughout the entire production process. After each shutdown, use specialized tools to clean material residue from the roller surface and gaps to prevent material hardening and adhesion, thus preventing uneven granulation in subsequent production. Simultaneously, use compressed air to blow away dust from inside the equipment to prevent dust from entering key components such as bearings and gears, which wou...

A bio-organic fertilizer granulation production line uses organic waste such as livestock and poultry manure and crop straw as raw materials, which are processed through harmless treatment and deep processing to produce granular fertilizer.  The entire process requires the coordinated operation of various specialized equipment, with each type of bio-organic fertilizer equipment precisely matched to each stage of production. The production process can be clearly divided into four main stages: pre-treatment, fermentation, deep processing, and post-treatment. Each stage is supported by core equipment, which can be flexibly adapted to different production capacities and raw material characteristics, ensuring continuous and orderly production and achieving standardized processing from raw materials to finished products. Pre-treatment equipment is the basic guarantee of production, and the core equipment includes crushers, screening machines, and mixers. The crusher can precisely crush...
