Phosphate rock serves as a fundamental raw material for producing phosphorus supplements in animal feed, playing a vital role in bone development, energy metabolism, and overall animal health. The bioavailability of phosphorus in feed supplements directly depends on the fineness and quality of the ground phosphate rock. Achieving the optimal particle size distribution through efficient grinding is therefore paramount for maximizing nutritional value and ensuring cost-effective production in the animal feed supplement industry.
Phosphate rock presents unique challenges in the grinding process due to its variable hardness, abrasiveness, and moisture content. Traditional grinding equipment often struggles with achieving consistent particle size while maintaining energy efficiency and operational reliability. The ideal grinding solution must address several key requirements:
Shanghai Zenith Machinery Co., Ltd., as an excellent manufacturer of ore grinding equipment in China, has made significant achievements in the field of ultra-fine powder grinding. Our specialized research, development, and production of industrial powder grinding equipment provide optimal solutions for phosphate rock processing in the animal feed industry.
For medium to large-scale phosphate rock grinding operations, the MTW Trapezium Grinding Mill stands out as an exceptional choice. This grinding mill incorporates multiple patents and features a compact structure, long service life, and eco-friendly design. Its ability to process materials with maximum input size of 50mm and produce final products as fine as 0.038mm makes it perfectly suited for animal feed supplement production.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW110 | <30 | 1.6-0.045 | 3-9 | 55 | 55 |
| MTW138Z | <35 | 1.6-0.045 | 6-17 | 90 | 110 |
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 | 200 |
| MTW215G | <50 | 1.6-0.045 | 15-45 | 280 | 315 |
The MTW series offers significant advantages for phosphate rock processing, including curved air duct design that reduces air flow resistance, internal efficient powder separator that ensures precise particle size distribution, and easy maintenance features that minimize downtime.
For operations requiring integrated processing capabilities, the LM Vertical Grinding Mill provides a comprehensive solution by integrating five functions—crushing, grinding, powder selection, drying, and material conveying—into a single machine. This vertical mill series offers small occupational area, produces fine final powder, and represents an eco-friendly production solution ideal for modern feed supplement facilities.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM130K | 1300 | 10-28 | 170-40 | <38 | 200 |
| LM190K | 1900 | 23-68 | 170-40 | <45 | 500 |
| LM280K | 2800 | 50-170 | 170-45 | <50 | 1250 |
The specific requirements for phosphate rock in animal feed supplements demand careful consideration of grinding parameters. The target particle size typically ranges between 100-400 mesh (149-37 microns), which ensures optimal bioavailability while maintaining good flow characteristics for mixing with other feed ingredients.
Key factors to consider include:
When selecting grinding equipment for phosphate rock processing, several factors must be evaluated. The MTW Trapezium Grinding Mill excels in applications requiring high capacity and precise particle size control, while the LM Vertical Grinding Mill offers advantages in space-constrained facilities and operations requiring integrated processing.
For ultra-fine applications where particle sizes below 400 mesh are required, the LUM Ultrafine Vertical Mill and XZM Ultrafine Grinding Mill provide additional options. The LUM1525 model, for instance, offers capacity of 1.6-11.5 t/h with size distribution D97 of 5-30μm, making it suitable for specialized high-value feed supplements.
Implementing advanced grinding solutions from Shanghai Zenith Machinery provides numerous operational benefits for animal feed supplement producers:
A major animal feed supplement manufacturer recently implemented the MTW215G Trapezium Grinding Mill for their phosphate rock processing line. The results demonstrated a 35% increase in production capacity while reducing energy consumption by 22% compared to their previous grinding system. The consistent particle size distribution achieved with the MTW215G improved product quality and reduced variation in their final feed supplements.
