In the field of non-metallic mineral powder processing, many business owners and engineers are still familiar with the classic Raymond mill. However, with the continuous improvement of global market requirements for capacity, energy consumption, and environmental protection, the limitations of the traditional Raymond mill are becoming increasingly apparent.
So, what are the essential differences between the traditional Raymond mill and its technological successor, the European trapezoidal grinding mill (MTW series)? What tangible benefits does the upgrade bring?
This article will provide a thorough comparative analysis to help you make the wisest investment decision.
I. Core Differences Comparison
We will visually demonstrate how the European trapezoidal grinding mill comprehensively surpasses the traditional Raymond mill from five key dimensions: transmission system, air duct design, grinding efficiency, environmental performance, and level of intelligence.
Comparison Dimensions: Traditional Raymond Mill vs. MTW European Trapezoidal Grinding Mill
Advantages Explained:
| Comparison Dimensions | Traditional Raymond Mill | MTW European Trapezoidal Mill |
| 1. Transmission System | Uses a reducer + open gear transmission, resulting in a long transmission chain, low efficiency (typically <90%), prone to oil leaks, rapid wear, and frequent maintenance. | Innovative vertical bevel gear integral transmission, with a short transmission path and efficiency exceeding 98%; thin oil lubrication, lifetime maintenance-free, and no risk of oil leaks. |
| 2. Air Duct Design | Straight-plate air ducts have high air resistance, are prone to material accumulation, leading to unstable output and high energy consumption. | Internal curved air ducts have low air resistance, are less prone to material accumulation, and ensure smooth air intake; the air duct plates have replaceable blades on all four sides, greatly extending wear life. |
| 3. Grinding Efficiency and Adaptability | The grinding roller device has grinding dead angles, making it difficult to "bite" flaky or slightly high-moisture materials, easily causing blockages and limiting efficiency. | The trapezoidal grinding roller and grinding ring design increases the contact area, eliminates dead angles, and improves grinding efficiency; it also offers greater adaptability to material moisture content. |
| 4. Environmental Performance | Typically, simple dust collectors are used, or additional dust collection systems are required, resulting in poor dust emission control and a poor workshop environment. | Standard configuration includes a high-efficiency pulse bag filter, with a dust removal efficiency of over 99.9%, and dust emissions far below international environmental standards, achieving green and clean production. |
| 5. Automation Level | Most operations are manual, highly dependent on operator experience, labor-intensive, and difficult to guarantee consistent product quality. | A PLC centralized control system can be used to achieve remote control, automatic feeding, and fault alarms, facilitating management and ensuring stable product quality. |
II. Technical Parameters of the MTW European Trapezoidal Grinding Mill
| Model | Roller Size (mm) | Grind Ring Size DxH(mm) | Main Roller Speed (r/min) | Max Feeding Size (mm) | Output Size (mm) | Capacity (t/h) | Power (Kw) | Overall Dimension (mm) |
| MTW110 | 360×210 | 1100×210 | 120 | 30 | 0.038-1.6 | 4-12 | 55 | 8910×6950×9010 |
| MTW138 | 460×260 | 1380×260 | 96 | 35 | 0.038-1.6 | 8-20 | 110 | 9860×8340×10227 |
| MTW175 | 520×300 | 1750×300 | 75 | 40 | 0.038-1.6 | 20-35 | 200 | 13500×11500×9500 |
| MTW215 | 640×340 | 2150×340 | 65 | 50 | 0.038-1.6 | 30-50 | 280 | 13922×9810×13226 |
