Features
The overall appearance adopts a streamlined design, offering an elegant and modern look, and is protected by national patent.
The front panel can be fully rotated and flipped upward, making complete roller assembly removal fast and convenient.
The feeding unit is independently rotatable, allowing easy cleaning of deposits in the feeding chamber, ensuring hygiene and efficiency.
All parts in contact with materials are made of food-grade materials, ensuring hygiene and an aesthetically pleasing appearance.
The MMR/MMRL Roller Mill is fully enclosed, ensuring safety and an attractive appearance, with electrostatic spray surface treatment.
The control system is sensitive and reliable, with stable centralized control.
A three-wheel system with toothed wedge belt transmission ensures no tooth skipping, no belt deviation, smooth operation, and low noise.
The elastic belt tensioning device automatically compensates for minor belt variations, extending service life.
The grinding rolls adopt self-aligning roller bearings to ensure precise concentric rotation and withstand high speed and grinding pressure.
High-quality double-head centrifugal cast grinding rolls are dynamically balanced, ensuring stable operation and long service life.
The grinding roll assembly is self-stressed, enabling highly precise and stable control of roll gap.
Fine roll gap adjustment features a simple, labor-saving structure with mechanical locking for quick and convenient operation.
A negative-pressure air suction system improves feeding conditions, reduces the temperature of grinding rolls and materials, and enhances grinding efficiency.
Scraper cleaning ensures more thorough cleaning, easy adjustment, roll protection, and reduced power consumption.
The base is integrally cast and machined from cast iron, providing stability, vibration reduction, and noise reduction, while the side frames are welded from high-quality steel plates and connected to the base using high-strength bolts.
The outer casing adopts a door-opening structure for easy access and maintenance.
Pneumatic control is used for engaging and disengaging the grinding rolls. A servo feeding speed control motor enables the grinding rolls and feed rolls to stop or operate as required. A material level sensor detects the material height, and the inverter adjusts the motor speed to regulate the feed roll speed, maintaining material balance.
