Production of phosphate rock fertilizer

Phosphate rock fertilizers are produced with high concentrations of phosphorus. Its main function is to promote plant growth, improve the quality of agricultural products and improve soil fertility. The production process of rock phosphate fertilizers mainly includes several steps, like crushing, grinding, drying and packaging of minerals. The equipment needed to produce rock phosphate fertilizer is made of carbon steel and is strong and durable..

What equipment is needed to produce rock phosphate fertilizer?

El equipo necesario para la rock phosphate fertilizer production includes crushers, Raymond mills and packaging machines. He equipo de trituración phosphate rock mainly uses a jaw crusher, The grinding equipment can choose a Raymond mill and the máquina de envasado uses a single bucket automatic packaging scale (doble).

jaw crusher

The main components of the jaw crusher are two toothed plates, one of which is fixed and the other is an oscillating toothed plate. The upper end of the tooth plate is fixed by a rotating sleeve and the lower end of the tooth plate can swing freely. When phosphate ore is added to the crusher, The active tooth plate is pushed against the fixed tooth plate to generate extrusion force by oscillating to crush the phosphate ore. When the active tooth plate is removed, crushed phosphate ore falls from the space between the two toothed plates. The rotation speed of the jaw crusher is usually 150 a 280 rpm for large equipment and 300 a 450 rpm for medium equipment.

The Raymond mill mainly achieves the crushing of phosphate ore through the rotation of the grinding roller device and the centrifugal force. The phosphate ore material to be crushed is added to the Raymond mill from the feeding hopper on the side of the machine cover.. The grinding roller device is suspended on the plum blossom frame of the main machine, rotating around the vertical axis and rotating at the same time. Due to centrifugal force during rotation, the grinding roller swings outward and presses against the grinding ring. The scraper sends the material between the grinding roller and grinding ring, and the purpose of crushing the material is achieved by rolling and rolling the grinding roller. Our Raymond mill feeds large particles and discharges ultrafine powder with an average particle size of up to 6,5 ​​um. Production indicators of the composites industry water soluble fertilizer powder.

Dryer

The main function of the drum dryer is to contact the material with hot air by rotating the cylinder to achieve drying., heating and other material effects‌‌.

Automatic single and double bucket packaging machine

Las máquinas envasadoras single barrel automatic (doble) are based on weighing sensors, weighing instruments and weighing transmitters to convert weighing signals into signals that can be recognized by the PLC. Luego se ejecutan varias acciones a través del control programable PLC. The entire weighing process is computer controlled and completed automatically. When the weight of phosphate fertilizer material reaches the set value. The system sends a control signal, Open the discharge door and the phosphate fertilizer material enters the packaging bag. After placement, discharge door closes automatically. When the bag holding device is released, the packaging bag will fall automatically, will be sewn and transported to the next station.

What is the production process of phosphate rock fertilizer?

The production process of phosphate rock fertilizer mainly includes several steps., how to crush minerals, mineral grinding, drying and packaging of the finished product.

The first is the crushing of minerals. The ore is crushed with a jaw crusher and crushed to a suitable particle size.

The second is mineral grinding. Crushed phosphate ore is ground into fine powder with a Raymond mill.

The next step is drying the phosphate fertilizer. The ground phosphate fertilizer is sent to a rotary drum dryer for dehumidification to obtain a standard compound phosphate fertilizer.

The last step is packaging. The dry phosphate fertilizer is weighed and packaged in an automatic packaging machine..
