How to Set Up a 10t per hour Production Line for NPK Granular Fertilizer
NPK granular fertilizer is a type of compound fertilizer that contains nitrogen, phosphorus and potassium. It is widely used in agriculture to improve crop yield and quality. NPK granular fertilizer can be produced by different methods, such as blending, extrusion, granulation and coating. In this blog post, we will introduce how to set up a 10t per hour production line for NPK granular fertilizer using the granulation method.
The granulation method is a process of converting powdery materials into granules by adding water or binder and applying mechanical force. The advantages of this method are that it can produce uniform and well-shaped granules, reduce dust pollution and save packaging costs. The main equipment for the granulation method are:
– Raw material batching system: This system is used to weigh and mix the raw materials according to the formula. The raw materials include urea, ammonium phosphate, potassium chloride, filler and additives. The batching system consists of several belt scales, hoppers, conveyors and mixers.
– Rotary drum granulator: This is the core equipment for the granulation process. It is a rotating cylinder with a certain inclination angle and a spray device inside. The raw materials are fed into the drum and sprayed with water or binder. As the drum rotates, the materials are agitated and rolled into granules. The size and shape of the granules depend on the rotation speed, inclination angle, moisture content and binder dosage of the drum.
– Rotary drum dryer: This equipment is used to dry the wet granules and reduce their moisture content to below 15%. The dryer is also a rotating cylinder with a heating device outside. The hot air enters the dryer from one end and exits from the other end. The drying time and temperature can be adjusted according to the product requirements.
– Rotary drum cooler: This equipment is used to cool down the hot granules and prevent them from caking. The cooler is similar to the dryer but with a cooling device outside. The cold air enters the cooler from one end and exits from the other end. The cooling time and temperature can be controlled according to the product specifications.
– Rotary drum screener: This equipment is used to separate the qualified granules from the unqualified ones. The screener is a vibrating sieve with different mesh sizes. The granules are fed into the screener and classified by their size. The oversized granules are returned to the granulator for re-granulation, while the undersized granules are recycled as raw materials.
– Coating machine: This equipment is optional but recommended for improving the appearance and quality of the granules. The coating machine is a rotating drum with a spray device inside. The granules are coated with a thin layer of oil or wax to make them shiny and prevent them from absorbing moisture and dust.
– Packing machine: This equipment is used to pack the finished granules into bags or bulk containers. The packing machine can be automatic or semi-automatic depending on the production capacity and budget.
The above equipment can form a complete 10t per hour production line for NPK granular fertilizer. The layout of the production line should be designed according to the site conditions, safety requirements and environmental standards. The production line should also be equipped with auxiliary devices such as dust collectors, fans, pipes, valves, electric control systems, etc.
The cost of setting up a 10t per hour production line for NPK granular fertilizer depends on various factors such as the equipment quality, configuration, installation, operation and maintenance. Generally speaking, the investment cost ranges from $500,000 to $1,000,000 USD. The operating cost mainly includes raw material cost, energy cost, labor cost and maintenance cost. The profit margin depends on the market demand, price and competition of NPK granular fertilizer.
