YGM Grinding Mill
YGM Grinding Mill
1-30 tons per hour.
Suitable for Gypsum, Limestone, Feldspar, Kaolin, Bentonite, Activated Carbon, etc.
Final powder size 0.033-0.613 mm
YGM high-pressure roller grinding mill is used to grind barite, limestone, ceramics, slag, and other non-flammable and explosive mining, metallurgy, chemical, building materials, and other industries with Mohs hardness below 9.3 and humidity below 6%.
More than 280 kinds For the high-fine milling of the material, the particle size of the finished product is adjusted in the range of 80-425 mesh (the finest 1000 mesh). In the main roller grinding mill high pressure grinding mill, a high-pressure spring with a pressure of 1000-1500 kg is fastened on the roller hanger. After starting to work, the grinding roller rotates around the main shaft, and rolls close to the grinding ring under the action of the high-pressure spring and centrifugal force. Its rolling pressure is 1.2 times higher than that of the Raymond mill under the same power conditions, so the output is greatly improved.
Structure of Roller grinding mill system
The YGM grinding mill is composed of main engine, classifier, pipeline device, blower, cyclone, jaw crusher, bucket elevator, vibrating feeder, etc. Among them, the YGM grinding mill is composed of main frame, air inlet volute, blade, grinding roller, grinding ring, cover and motor.
Working principle of Roller grinding mill system
The working process of the YGM grinding mill is to drive the central shaft to rotate through the transmission device. The upper end of the shaft is connected to the plum blossom frame. The frame is equipped with a grinding roller device and forms a swing fulcrum. The grinding roller itself rotates due to friction. The lower end of the plum blossom frame is equipped with a shovel blade system, which is located at the lower end of the grinding roller. During the same rotation of the shovel blade and the grinding roller, the material is shoveled and thrown into the ring of the grinding roller to form a bedding layer, which is generated by the rotation of the grinding roller. The outward centrifugal force (that is, the extrusion force) crushes the material, that is, the purpose of milling is achieved.

Why SMAT YGM grinding mill so popular?
- The entire YGM grinding mill is a vertical structure, with a relatively small footprint, strong systemicity, and strong completeness. Whether it is from the rough processing of raw materials, transportation, milling and final packaging, it can be an independent production system.
- Compared with other grinding equipment, the YGM grinding mill has a high passing rate, and the passing rate of the finished product after the YGM grinding mill can reach more than 99%, which is beyond the reach of other grinding equipment.
- The electromagnetic vibrating feeder is used for uniform feeding, easy adjustment, small size, light weight, fuel saving and electricity saving, and convenient maintenance.
- The electric adopts centralized control and advanced selection, and unmanned operation can be realized in the control
- The transmission device of the main engine adopts a closed reducer, which has stable transmission, reliable operation and no oil leakage.
- The blade holder of the main engine is always in contact with the material during operation, so the blade holder is composed of upper and lower parts. After the lower seat is worn, the connecting bolts can be removed and replaced.
- The important parts of YGM grinding mill are made of high-quality castings and steel. The fine craftsmanship and rigorous process ensure the durability of the entire set of equipment.
Q:How the YGM grinding mill system ensure final powder fineness?
The classifier drives the blades on the turntable to rotate through the speed-regulating motor and decelerates to form a classification effect on the powder. The speed of the blade speed is adjusted according to the size of the finished powder. When it is necessary to obtain finer-grained powder, the rotating speed of the blade must be increased to increase the contact between the blade and the powder, so that the unsatisfactory powder is thrown by the blade to the outer wall and separated from the airflow, and the coarse powder falls into the air due to the action of self-gravity. The grinding chamber is re-ground, and the qualified finished powder is sucked into the cyclone by the blade along with the airflow. After the airflow and the powder are separated, the powder is collected.
Q:How to choose suitable YGM grinding mill system?
We have engineer team specially for project solution designing, they will calculate based on your project requirement, such as the hourly capacity, input and output size, etc.
Please contact us for free project designing.Q:Ball mill or YGM grinding mill system, which one is better?
Both of them have it’s own advantages, YGM grinding mill is suitable for non-metallic ores, and it requires less spare parts, compared with ball mill. Grinding media is necessary spare parts for ball mill.
On the other hand, user has to choose ball mill for wet grinding.
