Loader Type Feeder: Enhancing Material Handling Efficiency

To kickstart the granulation process, a loader type feeder efficiently transfers raw materials to this press pelletizing production line. This automated system ensures continuous and uniform feeding, minimizing downtime and maximizing production efficiency.

Crain Crusher: Preparing Raw Materials for Granulation

Next in line is the crain crusher, tasked with breaking down raw materials into smaller, uniform particles. From compost and gypsum to livestock manure and bio-sludge, the crain crusher ensures consistent material size, facilitating smoother granulation and superior pellet quality.

Horizontal Mixer: Homogenizing Material Composition

Once crushed, the raw materials are blended in a horizontal mixer to achieve a uniform composition. This crucial step ensures an even distribution of nutrients and additives, optimizing the quality and effectiveness of the final fertilizer pellets.

Rotary Screening Machine: Ensuring Pellet Uniformity

Following granulation, the rotary screening machine sifts and separates the fertilizer pellets based on size. This critical step eliminates oversized or undersized pellets, ensuring uniformity in the final product and maximizing marketability.

Automatic Packaging Scale: Streamlining Packaging Operations

To conclude the dry powder press granulation process, an automatic packaging scale precisely measures and packs the fertilizer pellets into bags or containers. This automated system enhances efficiency and accuracy, reducing labor costs and minimizing packaging errors.
