Features and Working Principle of Double Roller Press Granulator

图片
The double roller press granulator is a drying-free granulation equipment based on high-pressure physical extrusion molding technology. It is widely used in fertilizers, chemicals, pharmaceuticals, feed, and other fields. With its high efficiency, energy saving, and wide adaptability, it has become the preferred equipment for small and medium-sized production enterprises. Its core working logic and unique performance constitute the core competitiveness of the equipment. The following details its working principle and main features. The working principle of the double roller press granulator is based on dry extrusion molding, eliminating the need for high-temperature drying and additional binders. The core process consists of four steps. First, power transmission: the motor drives the reducer via a belt pulley, and then the drive shaft drives the driven shaft to achieve synchronous reverse rotation, ensuring precise and consistent rotation speed of the two rollers. Second, extrusion m...

Why are bio-organic fertilizer production lines so popular?

图片
In recent years, bio-organic fertilizer production line s have become a popular choice in the agricultural equipment sector, with large-scale farms, organic planting bases, local circular agriculture parks, and small and medium-sized processing enterprises all accelerating their deployment. The continued popularity of this production line stems from the combined effects of policy guidance, market demand, ecological value, and economic benefits, making it a key vehicle for the transformation of green agriculture. Policy dividends are a significant driving force. Currently, there is a strong push for actions such as "organic fertilizer replacing chemical fertilizer" and "resource utilization of livestock and poultry manure," with many regions providing equipment subsidies and tax incentives for organic fertilizer production lines to encourage the resource utilization of agricultural waste. At the same time, increasingly stringent environmental requirements make tradit...

How to Select Equipment for a Fertilizer Production Line?

图片
The selection of equipment for a fertilizer production line directly determines production efficiency, product quality, and operating costs, making it a core aspect of the production process for fertilizer companies. Scientific selection requires basing it on the company's own production needs, considering practicality, adaptability, and economy, avoiding blindly pursuing high-end or low-priced options. This is crucial for achieving a dual improvement in capacity and efficiency. Below are specific selection points. Based on production scale and capacity, accurately matching equipment specifications is the primary prerequisite for selection. Small production lines can choose equipment with simple structure, small footprint, and high cost-effectiveness, such as static batching machines, drum mixers, and semi-automatic packaging machines. Excessive automation is unnecessary, reducing initial investment costs. Medium-sized production lines require highly efficient, interconnected equi...

What are the common equipment used in bio-organic fertilizer production?

图片
In the wave of green agricultural development, bio-organic fertilizers are widely used due to their advantages in improving soil and crop quality. Their standardized production relies heavily on various specialized equipment. From raw material processing to finished product packaging, equipment at each stage plays a crucial role, improving production efficiency and ensuring fertilizer quality. Below, we introduce common equipment used in bio-organic fertilizer production . Raw material pretreatment equipment is the foundation of production, with core components including crushers and mixers. Raw materials such as straw and livestock manure need to be crushed to a suitable particle size by a straw crusher to increase the specific surface area, facilitating subsequent fermentation and decomposition. For small-scale production, a hammer mill can be used, which is efficient and inexpensive. The mixer is used to evenly mix the crushed main and auxiliary materials with the fermentation agent...

Why is Granulation Necessary for Bio-organic Fertilizer?

图片
Bio-organic fertilizer, as a golden combination of organic matter and functional microorganisms, is an important support for promoting the green transformation of agriculture and improving soil. However, many people wonder why a granulation process is added to the production of bio-organic fertilizer .In fact, granulation is not an unnecessary process. Relying on a professional bio-organic fertilizer production line , it becomes a key measure to balance microbial activity, fertilizer efficacy, and practical application. It directly determines the quality and use value of bio-organic fertilizer and is a core means of solving its application pain points. Granulation effectively protects the functional microbial community in bio-organic fertilizer, extending its fertilizer effect cycle. The core advantage of bio-organic fertilizer lies in its beneficial microorganisms, which can decompose soil nutrients and inhibit harmful bacteria. However, these microorganisms are sensitive to the envir...
