Zhejiang Tongli Heavy Machinery Co., Ltd products

The drum dryer is a piece of equipment specially developed by tongli for the drying of npk compound fertilizer. Since the 1990s, tongli has provided drum dryers of different specifications and models to the world’s top 500 fertilizer companies.

Tongli steam granulation NPK compound fertilizer production line typically involves raw material preparation, steam granulation, drying, cooling, screening, coating, and packaging. Raw materials are mixed and then subjected to high-pressure steam to form granules. This process ensures uniform distribution of nutrients and improves the physical properties of the fertilizer, such as granule size and strength, ultimately enhancing its effectiveness in agricultural applications.

A Tongli double roller extrusion NPK compound fertilizer production line is a system designed for the manufacturing of NPK compound fertilizers through a specialized extrusion process. This process involves blending raw materials such as urea, ammonium phosphate, and potassium chloride in predetermined ratios, then subjecting the mixture to high pressure and temperature within the extruder to form granules.

Tongli high tower prilling NPK compound fertilizer production line designed for the manufacturing of complex fertilizers containing high nitrogen content, phosphorus, and potassium in precise proportions. The process typically involves raw material preparation, blending, granulation, drying, cooling, and packaging. The “high tower” aspect refers to the vertical design of the equipment, which allows for efficient heat transfer and optimal control over particle size and distribution during prilling, a method of forming small spherical pellets. This production line is capable of producing high-quality NPK fertilizers with tailored nutrient compositions.

An organic-inorganic NPK compound fertilizer production line combine both organic and inorganic components to provide a balanced blend of essential nutrients for plant growth. It consists of various stages including raw material preparation, mixing, granulation, drying, cooling, screening, coating, and packaging. Organic materials such as compost, manure, or plant residues are combined with inorganic substances like nitrogen (N), phosphorus (P), and potassium (K) to create a fertilizer with enhanced nutrient content and improved soil fertility.
