Brief Introduction

YGM Raymond Roller Mill is suitable for processing various non-lammable and non-explosive mineral materials with Moh’s hardness less than 6 and humidity less than 6%. 
It is widely used in the fields of metallurgy, construction, chemical industry, mining, highway construction etc, The granularity of the finished powder size can be adjusted between 50 and 325 meshes (315-45 micron). Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore, carborundum, bauxite, rock phosphate, coal and other materials, total about 400 kinds of materials.

Working Principle

The Raw materials by jaw crusher less than 20mm and lifted by the elevator to the storage hopper, then after vibrating feeder evenly and quantitatively and continuously into the Main machine grinding, grinded powder was blow by airflow away. Through the classifier separated, consistent with the powder fineness with air flow through the pipeline into the cyclone collector, were isolated and collected, and then by the powder in tube is discharged into the finished powder. Air flow from large cyclone collector is arranged at the upper end of the air return pipe suction blower. The air current of the whole system is a closed loop, and flow circulation in the positive and negative pressure condition.

Performance and Advantages

1. The production volume is 20% to 30% higher than R Raymond mill;
2.The increase mechanism of linkage pressure of the rollers, which greatly prolongs the useful life of the equipment and increases the capacity by 20% under the same power;
3.With the original roller assembly, the oiling time increased 6 – 15 times, archive the application of oil once, use for 30-45 days;
4.High efficiency and stability, the ring and roller always contact during processing, the efficiency and stability of the grind are improved;
5.Higher Accuracy powder Classify, without coarseness missing, Variable frequency Squirrel cage classifier(Patent product) is adopted, the accuracy is 80-600 meshes. The classify efficiency reached 99%. The powder selection is stable and adjustable, compare with the blade type, it can greatly improve the powder selection efficiency and qualification rate of the Final product.
