150 Mesh Gypsum Powder Production Line: Key Equipment and Process Guide

Introduction

Gypsum powder, a versatile material widely used in construction, agriculture, and industrial applications, requires precise processing to meet specific fineness standards. A 150 mesh (approximately 100 microns) product is a common specification for many industrial uses, demanding a balance between production efficiency, energy consumption, and product quality. Establishing a reliable and efficient 150 mesh gypsum powder production line involves a systematic process flow and the selection of appropriate key equipment. This guide provides a comprehensive overview of the production process and highlights critical machinery, with a focus on achieving optimal performance for your investment.

The Production Process: From Raw Gypsum to 150 Mesh Powder

The transformation of raw gypsum rock into fine 150 mesh powder follows a logical sequence of size reduction, drying, grinding, and collection. Each stage is crucial for ensuring final product quality and line efficiency.

1. Primary Crushing

Large raw gypsum rocks (typically 0-300mm) are first fed into a primary crusher, such as a jaw crusher or hammer crusher, to reduce their size to a manageable dimension, usually below 50mm. This step is essential for facilitating subsequent drying and grinding processes.

2. Drying

Raw gypsum often contains inherent moisture. A rotary dryer or vertical flash dryer is employed to reduce the moisture content to below 1-2%. Efficient drying is critical, as excessive moisture can lead to clogging in the grinding mill and reduce overall system efficiency.

3. Secondary Crushing & Grinding

This is the core stage for achieving the target 150 mesh fineness. The pre-crushed and dried gypsum is fed into a grinding mill. For a 150 mesh product, medium-fine grinding equipment is ideal. The choice of mill significantly impacts productivity, energy use, and product particle size distribution.

4. Classification

Integrated within or attached to the grinding mill, a classifier (often a dynamic turbo classifier) separates the ground powder. Particles meeting the 150 mesh specification are carried away by airflow to the collection system, while oversized particles are returned to the grinding chamber for further milling. This closed-circuit system ensures precise size control.

5. Collection & Packaging

The fine powder-air mixture enters a high-efficiency cyclone collector and a bag filter or pulse dust collector. Here, the finished 150 mesh gypsum powder is separated from the air stream. The collected powder is then conveyed to storage silos and finally packaged for shipment.

Key Equipment Selection for 150 Mesh Output

Selecting the right grinding mill is paramount. While ball mills are a traditional choice, modern roller mill technology offers superior energy efficiency and control for applications like 150 mesh gypsum production.

Critical Considerations:

• Feed Size: The mill must handle the output from your primary crusher/dryer (typically ≤30-50mm).
• Product Fineness: The equipment must reliably and consistently produce powder in the 150 mesh (100μm) range with a tight particle size distribution.
• Capacity: The mill’s throughput (e.g., tons per hour) must match your production goals.
• Energy Efficiency: Grinding is energy-intensive. Mills with higher grinding efficiency directly lower operational costs.
• System Integration: A well-designed mill system includes integrated classification, drying capability, and dust collection interfaces.

Recommended Equipment: MTW Series European Trapezium Mill

For producing 150 mesh gypsum powder with excellent efficiency and reliability, our MTW Series European Trapezium Mill is an outstanding solution. Its design is particularly well-suited for medium-fine grinding applications in the 30-325 mesh range.

*Capacity varies based on material characteristics and fineness requirements.

Why the MTW Mill is Ideal for 150 Mesh Gypsum:

• Optimized Grinding Geometry: Its curved shovel blade and grinding roller/ring design create an efficient grinding bed, perfect for brittle materials like gypsum, ensuring high throughput at 150 mesh.
• High-Precision Integral Classifier: The bevel gear-driven classifier allows for stepless adjustment of fineness, providing exact control over the 150 mesh product size with minimal oversize particles.
• Energy Efficient Drive: The integral bevel gear transmission has an efficiency of up to 98%, reducing power loss compared to traditional worm gear systems.
• Durable & Low Maintenance: Features like anti-wear shovel blades and a wear-resistant volute structure reduce maintenance frequency and cost, ensuring stable long-term operation.

Advanced Alternative for High-Value or Ultra-Fine Applications

For producers aiming at higher-value markets or considering future expansion into ultra-fine gypsum products (e.g., 325-2500 mesh for specialized plastics or paints), investing in a more advanced platform from the start can be strategic.

Recommended Advanced Equipment: SCM Series Ultrafine Mill

Our SCM Series Ultrafine Mill represents the forefront of fine and ultra-fine grinding technology. While capable of producing 150 mesh powder with exceptional efficiency, its true advantage lies in its ability to seamlessly produce much finer products without major system changes.

Key Advantages for Future-Proofing Your Line:

• Wide Fineness Range: From 325 to 2500 mesh, it can produce 150 mesh gypsum with ease while offering unmatched flexibility for premium product lines.
• Superior Particle Classification: The vertical turbine classifier achieves extremely sharp particle size cuts, resulting in a more uniform 150 mesh product with a steeper distribution curve, which can enhance performance in downstream applications.
• High Efficiency & Energy Saving: The grinding principle offers capacity twice that of jet mills with approximately 30% lower energy consumption, making it economical even for standard fineness production.
• Turnkey System: It comes as a complete system with built-in crushing, grinding, classification, and collection, simplifying plant design and installation.

Conclusion

Building a successful 150 mesh gypsum powder production line requires careful planning of the process flow and, most importantly, the informed selection of core grinding equipment. While several mill types can achieve the target fineness, the choice between a highly efficient medium-fine mill like the MTW Series and a versatile, future-ready ultra-fine mill like the SCM Series depends on your specific production goals, product portfolio strategy, and operational priorities. Focusing on energy efficiency, maintenance costs, and product quality consistency will ensure your production line remains competitive and profitable in the long term. Consulting with experienced equipment suppliers to analyze your raw material and market requirements is a critical step in this process.
