Sulfurization bed drying equipment (fluidized bed dryer) Commonly known as boiling bed drying equipment, it belongs to the continuous/intermittent drying equipment for granular powder, and is widely used in the organic fertilizer, compound fertilizer, chemical, and feed industries Working principle of sulfurization bed drying equipment After filtering and heating, the hot air passes through the porous gas distribution plate from the bottom and blows upwards; When the airflow velocity reaches the minimum fluidization velocity, solid particles on the bed are suspended by the airflow, and the particles roll and boil with each other (fluidization, where solids flow like liquids); Hot…

A Compound Fertilizer High Tower Granulation Production Line is an advanced industrial system designed to produce granular compound fertilizers—fertilizers containing two or more essential nutrients (e.g., nitrogen, phosphorus, and potassium) in a single, homogeneous granule. This production method is named for its signature high tower structure, which enables efficient granulation through free-falling materials and natural cooling. It’s widely adopted in the fertilizer industry for its high output, uniform product quality, and energy efficiency. Below is a detailed breakdown of its working principle, key components, advantages, and applications.  Compound Fertilizer High Tower Granulation Production Line  Working Principle The core principle of this production…

A fertilizer dryer is an industrial equipment specifically designed to reduce the moisture content of fertilizer materials. Its core function is to evaporate excess moisture from fertilizers during production (e.g., after fermentation or granulation) through heat transfer, ensuring the moisture content meets national quality standards or requirements for storage and transportation. It also improves the physical properties of fertilizers (such as preventing caking and facilitating subsequent packaging), making it a core device in the "drying section" of the fertilizer production chain. I. Core Functions of a Fertilizer Dryer Fertilizers (especially organic fertilizers and compound fertilizers) retain large amounts of moisture due…

    There are two forms of extrusion and throwing granulators: ① Integrated extrusion and throwing main machine (a single machine first extrudes and then rolls and shapes the inside); ② Split type production line: double roll extrusion granulator+rear round throwing machine (two devices connected in series), the split type solution is more common in organic fertilizer factories. Working Principle: 1. Squeezing section: Powdered organic fertilizer/organic-inorganic compound fertilizer materials are extruded by spiral or roller extrusion, first extruding strip-shaped or flattened coarse particles (wet state, with certain plasticity; both dry and semi wet methods can be used); 2. Round polishing…

What is a Fertilizer Cooler? A fertilizer cooler is a core auxiliary equipment in the production process of granular fertilizers such as compound fertilizers and organic fertilizers. Its main function is to quickly and evenly cool down the high-temperature fertilizer granules after granulation and drying, while removing part of the residual moisture. It provides a qualified material foundation for subsequent processes such as screening, coating, and packaging, and is one of the key equipments to ensure the quality of fertilizer products and improve production efficiency. Core Functions and Working Principles of Fertilizer Coolers 1. Core Functions After being processed by…

Venturi washing equipment (Venturi washer) It belongs to high-energy wet scrubbing and dust removal equipment, commonly used for high-temperature flue gas dust removal and cooling, and can also synergistically absorb some acidic waste gases (SO ₂, HCl, etc.). Main structure of Venturi washing equipment The whole system is divided into four parts: Venturi tube body, gas-liquid dehydration separator (cyclone dehazing), water circulation system, and induced draft fan Three sections of the Venturi tube body: 1. Shrinkage tube (tapered section): the flow cross-section is reduced, and the airflow is accelerated; Spray washing water into this or the throat position 2. Throat…

A chain plate compost turner is a type of equipment used in the composting process, which mainly relies on chain-driven plates to turn, stir and aerate organic materials, accelerating the decomposition of compost. Core Structure The chain plate compost turner is composed of several key components, each of which plays a vital role in the composting process. Chain Plate Assembly: The core working part, consisting of chains and evenly distributed plates. The plates are usually made of wear-resistant steel to withstand friction from organic materials. Transmission System: Includes motors, reducers and chains. It provides power to drive the chain plate…

Industry standard name: Horizontal Box type High temperature Aerobic Fermentation Equipment, commonly known as Box type Fermentation Tank, Fermentation Box, Integrated Fermentation Warehouse, specialized in processing solid organic waste as organic fertilizer, different from vertical circular fermentation tanks and liquid fermentation tanks. Working principle of box type fermentation tank foundation Fully automatic high-temperature aerobic fermentation inside a sealed box Raw material pretreatment: adjust the moisture content of livestock manure/sludge/kitchen waste+straw auxiliary materials to 55%~65%, carbon nitrogen ratio to 25:1, and add fermentation agents; Sealed feeding: The belt conveyor sends the material into the insulation box; Stirring+Bottom Aeration: The main shaft…

The bulk crusher generally refers to the first coarse crushing equipment on the production line, which is specialized in processing large-sized raw materials. It is commonly used for mining, construction waste, organic fertilizer lumps, and coal blocks. The mainstream is divided into four categories: jaw crusher, heavy hammer (box type) crusher, gyratory crusher, and biaxial shear crusher. 1. Jaw crusher (jaw crusher, most commonly used large head crusher) Principle: The moving jaw plate oscillates back and forth, squeezes, bends and crushes materials, and has a V-shaped large feed inlet. -Feed: up to 1200-1500mm stones; -Advantages: Not afraid of hard materials…
