Turn Limestone Powder into Premium Mineral Fertilizer: Complete Granulation Production Lines

Raw limestone, dolomite powder, and gypsum are widely used as mineral fertilizers and soil conditioners. However, handling fine mineral dust causes heavy material loss, creates severe dust pollution, and clogs farm spreaders.

Processing raw mineral dust into dust-free, uniform 2 to 4 mm mineral fertilizer granules solves field application problems and increases your product selling value by 3 to 4 times.

As a direct fertilizer equipment manufacturer, we engineer and build heavy-duty mineral fertilizer granulation production lines. Our machines are specifically designed to handle dense, abrasive mineral powders without machine clogging or frequent breakdowns.

Common Production Bottlenecks & How Our Equipment Solves Them

Mineral Powder Won't Form Pellets Easily?

Our Twin-Shaft Paddle Mixer uses high-speed rotating blades and built-in liquid spray bars to thoroughly mix dry mineral powder with water and binder liquid before pelleting begins.

Heavy Abrasion & Sticky Inner Walls?

Our Mineral Rotary Drum Pelleting Machine is fitted with special anti-stick plastic inner linings and heavy-duty steel wear plates, preventing wet mineral powder from sticking and extending machine lifespan by 3 to 5 times.

Soft Granules & Excessive Dust?

Our Rotary Dryer & Cooler system strips moisture out down to below 1%, making the finished mineral granules hard, strong, and easy to store without crushing.

Complete Mineral Fertilizer Granulation Line Workflow

• Automatic Raw Material Batching System: Accurately weighs and feeds limestone powder, gypsum, and binder materials into the line.

• Twin-Shaft Paddle Mixer: Evenly blends dry mineral powder with liquid binder so the material is ready for granulation.

• Mineral Rotary Drum Granulator: Rolls moist powder into round, uniform granules at high speeds (3--30+ tons/hour).

• Rotary Drying & Cooling System: Dries and cools hot granules while built-in dust collectors keep your workshop 100% dust-free.

• Vibrating Screen & Crusher: Separates ideal-sized granules (2--4 mm; oversized pellets are crushed and returned for 100% material recycling.

• Automatic Bagging Machine: Automatically weighs, fills, and sews 25 kg, 50 kg, or 1-ton jumbo bags.
