A double roller press  granulator is a highly efficient and energy-saving dry granulation equipment, widely used in chemical, fertilizer, and building materials industries, playing a crucial role, especially in fertilizer production line s. Its core principle is to use high-pressure mechanical extrusion to shape powdery materials through intermolecular forces, eliminating the need for additional binders and achieving green and efficient granulation throughout the process. The core power source for the equipment is the transmission system. An electric motor drives a pulley, which, after being reduced in speed and torque by a reducer, drives a pair of parallel high-pressure rollers to rotate at a relatively uniform speed. The transmission methods vary slightly between different models; some use split gears to achieve double-roller linkage, while others are directly driven by a reducer with dual output shafts, ensuring synchronous rotation and balanced pressure between the two roller...

A double roller press  granulator is a molding equipment that transforms powdered materials into regular granules based on the principle of dry extrusion. Also known as a double roller granulator , it is widely used in various industrial fields due to its high efficiency, energy saving, and convenient operation, becoming one of the core equipment in modern particle processing. It eliminates the need for complex drying and cooling processes, relying on mechanical high pressure to achieve material molding, and is suitable for the granulation needs of various powdered raw materials. Its working principle is simple and efficient. The core structure consists of two parallel, counter-rotating extrusion rollers and auxiliary systems such as feeding, transmission, and lubrication. Powdered material is evenly fed between the two rollers by the feeding system. Under the high pressure driven by hydraulics, the intermolecular forces of the material are enhanced, and the material is forcibly s...

Fermentation and maturation are the core stages in the bio-organic fertilizer production line . Through the activity of aerobic microorganisms, organic raw materials are decomposed, pathogens and insect eggs are killed, achieving harmlessness and stabilization. The efficient completion of this process relies on suitable professional equipment, with different equipment corresponding to different fermentation modes and adapting to diverse production needs. Turning equipment is the key to fermentation and maturation, directly determining fermentation efficiency and maturation quality. Windrow compost turning machine s are suitable for open-air windrow fermentation.  Their crawler design allows them to move flexibly between material piles, and the turning teeth penetrate the material layer, ensuring thorough material turning and oxygen supply while also lowering the pile temperature. They are suitable for windrows of conventional width and height, and ideal for small and medium-sized ...

In granulation processes across various fields such as chemical engineering, building materials, and agriculture, disc granulator s consistently maintain high sales, becoming the preferred equipment choice for businesses. Their popularity is not accidental, but rather the inevitable result of a perfect match between performance advantages, application versatility, and industry trends, comprehensively meeting the core needs of businesses for efficient production and cost control. Superior performance is the foundation of their market success. Compared to traditional equipment, disc granulators have achieved a qualitative leap through technological upgrades.  They utilize large-diameter slewing bearings and planar support designs, ensuring stable and vibration-free operation. The granulation rate can reach over 85%, producing highly uniform and strong granules, directly improving subsequent production efficiency. Furthermore, they offer significant energy savings, consuming only 0.7-...

Bio-organic fertilizers are made from various organic waste materials combined with functional microbial agents. This process not only achieves resource recycling but also improves soil and enhances crop quality. The raw materials for bio-organic fertilizer production line s are diverse and can be divided into three main categories based on their source: core organic raw materials, auxiliary conditioning raw materials, and functional additive raw materials. Core organic raw materials are the main carriers of nutrients, mostly consisting of agricultural, forestry, animal husbandry, and fishery waste. Livestock and poultry manure, such as chicken manure, sheep manure, and cow manure, are rich in nitrogen and organic matter, quickly replenishing soil nutrients, but require thorough fermentation to kill pathogens. Crop straws and husks, such as corn stalks, rice husks, and peanut shells, have high carbon content and can regulate the carbon-nitrogen ratio during fermentation and improve soi...

As a core piece of equipment in the agricultural industry chain, the service life of a fertilizer production line directly impacts production efficiency, product quality, and corporate economic benefits. Due to factors such as raw material characteristics, operating environment, and operating methods, production lines are prone to problems such as equipment wear and component aging. Through scientific management and systematic maintenance, the service life of the production line can be effectively extended, achieving cost reduction and efficiency improvement. Effective daily equipment maintenance is fundamental. A comprehensive inspection system should be established, with daily checks of the operating status of core equipment such as granulators, dryers, and screening machines.  Key indicators such as bearing temperature, lubricating oil level, and sealing performance should be checked, and any abnormal noises or leaks should be addressed promptly. Equipment should be regularly c...
