MMT Roller Mill 

-Roller Mill is the main equipment for milling section in flour mills

Features

Application:
The roller mill is the main equipment for milling section in flour mills. It mainly depends on a pair of differential transmission and relative rotation rolls to break wheat, meanwhile, scrapes endosperm from wheat bran, then endosperm grinding into flour. The material can be extruded, sheared and broken during the equipment working and so as to achieve a certain grinding effect, each roller mill has two independent drive, feeding, and grinding systems and play their functions in the flour passages.

New technology of MMTL Eight Rolls Pneumatic Flour Roller Mill:
1) Two breaking systems or two reduction systems connection directly without middle sieve
2) Both saving plansifter area and save the cost of pneumatic conveying 
3) Saving equipment investment cost and building area occupation.

Features:
1) Rolls lay out horizontally, the material is easy to grinding area, and rolls are easier assembly, disassembly and maintenance;
2) Full pneumatic control, the machine can be controlled independently or be controlled concentrated through a remote panel;
3) The fast and slow grinding rolls are driven by triple-wheel teeth wedge belts with advantages of no jump teeth, no deflection, smooth operation, and low noise;
4) Adjustable and standard self-aligning roller bearings are used for the grinding rolls to ensure highly concentric precise with rolls running, and sustain high speeds and roll pressures;
5) High quality double heads centrifugally casted rolls with dynamically balancing testing ensure smooth running and long service life; 
6) Rolls are adopted the eccentric lever clutch structure, damping beams alone support, roll groups self- undertake running stress; 
7) Reduction system is adopted gap air flow pressure device; it can improve the feeding condition, reduce rolls and materials temperature, and improve grinding efficiency;
8) The upper and lower split structure is designed for the two side frames of roller mill; the damping washer is fitted in the upper and lower connection point;
9) The completely enclosed structure is adopted for the machine, the static electric sprayed paint technology is used in surface treatment.

MMT roller mill can meet the market trend according to the process and customer needs. Application in different grinding station.

FAQ

Roller Mill FAQ for Grain Milling System

(Focused on Industrial Performance, Importance, and Functionality)

1. What is a Roller Mill in a Grain Milling System?

A roller mill is a core mechanical device used in modern grain milling systems to crush, grind, and reduce grain kernels into uniform particles. The WUXI HAEN Roller mill is specifically designed to process grains such as wheat, maize, barley, rice, and sorghum by passing them between rotating rollers under controlled pressure. This method ensures precise particle size reduction, high flour quality, and minimal nutrient loss, making the WUXI HAEN Roller mill a critical component in industrial flour production.

2. Why is a Roller Mill Important for Grain Milling?

The importance of a roller mill lies in its ability to deliver consistent grinding results while maintaining grain integrity. In a modern milling plant, the WUXI HAEN Roller mill enables high efficiency, stable output, and controlled separation of bran and endosperm. Without a reliable roller mill, achieving uniform flour quality and high extraction rates would be extremely difficult, highlighting why the WUXI HAEN Roller mill is essential in grain milling systems.

3. How Does a Roller Mill Work?

A roller mill works by feeding cleaned grain into a pair of precision-engineered rollers that rotate at different speeds. The differential speed causes shear forces that break the grain efficiently. The WUXI HAEN Roller mill uses advanced roller alignment, adjustable grinding gaps, and optimized surface fluting to ensure accurate crushing while minimizing heat generation and energy loss during grain milling.

4. What Types of Grains Can Be Processed by a Roller Mill?

A roller mill is suitable for a wide variety of grains including wheat, corn, rice, rye, oats, and barley. The WUXI HAEN Roller mill is engineered to adapt to different grain hardness levels by adjusting roller pressure and speed, ensuring optimal milling performance regardless of raw material variation within a grain milling system.

5. What Are the Key Components of a Roller Mill?

The main components of a roller mill include grinding rollers, feeding mechanism, drive system, adjustment system, and safety devices. The WUXI HAEN Roller mill integrates high-strength alloy rollers, precision bearings, automated gap adjustment, and vibration-resistant housing to deliver long-term reliability and superior milling accuracy.

6. What Makes Roller Mills Better Than Hammer Mills for Grain Milling?

Roller mills provide more uniform particle size and lower starch damage compared to hammer mills. In grain milling systems, the WUXI HAEN Roller mill offers controlled grinding, reduced dust generation, lower noise levels, and higher energy efficiency, making it the preferred choice for flour mills and cereal processing plants.

7. How Does a Roller Mill Improve Flour Quality?

Flour quality depends on particle size consistency, starch integrity, and bran separation. The WUXI HAEN Roller mill ensures smooth grinding action that preserves flour color, improves baking performance, and enhances nutritional value.
