YGM Industrial Raymond Mill

Industrial Raymond mill, also known as YGM Raymond mill and Raymond machine, is a high efficiency pulverizing mill that replaces ball mills to process ore powder. The product has outstanding advantages such as strong systematicness, high screening rate, smooth transmission, high wear resistance and convenient maintenance. It is widely used in the grinding and processing of mineral materials in mining,

Raymond mill is widely used in the powder processing of barite, calcite, potassium feldspar, talc, marble, limestone, ceramics, glass and other non-flammable and explosive materials with Mohs hardness not greater than 7 and humidity below 6%. The fineness of the finished product is between 80 and 600 mesh. Through the joint action of the analyzer and the fan, it can meet the requirements of different users.

2. Soft connection structure under the cover tube, the cover tube will never crack:

The traditional mill hood and the main engine bolts are hard connected, and the vibration transmitted to the hood can easily cause the hood to crack, and the bolts are fatigued and fractured by shearing force.

The pulverizer adopts a separate cover cylinder, which is fixed with bolts of the analyzer, and the cover cylinder is softly connected to the host. During the use process, the cover cylinder is free from force and vibration, so that the cover cylinder will never crack.

3. Reinforced air return box, double-row bolt connection

4. The central shaft of the main engine will never wear out, and the replacement of the seals on the lower part of the central shaft of the main engine is simple and convenient:

◆ For the sealing part of the central shaft of the traditional Raymond mill, after working for a certain period of time, the skeleton oil seal of the central shaft wears and forms grooves, resulting in the leakage of lubricating oil at the sealing part.

When replacing the oil seal, the main engine must be disassembled, and the center shaft frame must be disassembled and turned upside down to replace the seal (oil seal), and the workload is larger than the replacement of the grinding ring.

Improvements compared to traditional Raymond mills

1. Improvement of the main engine: the grinding roller and the grinding ring are increased, and the shovel blade is increased to increase the grinding surface and grinding force to increase the output.

2. Improvement of the reducer: The reducer is changed to a new type of reducer, and the speed of the main engine can be changed from a single speed to a suitable adjustment of the main engine speed according to the needs of users, and the grinding force can be increased to increase the output.

3. Improvement of the classifier: The classifier adopts a built-in large-blade cone turbine classifier, and the particle size of the finished product can be adjusted arbitrarily within 80-600 mesh, which improves the classification accuracy and airflow passing area.

4. Improvement of cyclone collector: The cyclone collector is changed to a parallel four cyclone collector, which improves the collection efficiency by more than 10%25 compared with the single cyclone.

5. Fan improvement: The blower is changed from an ordinary fan to a high-pressure fan, and the wind pressure is doubled, which greatly improves the pneumatic conveying capacity.

Features of YGM Raymond mill:

◆ One-time crushing efficiency is high

◆ Soft connection structure under the cover tube, the cover tube will never crack

◆ Reinforced air return box, double row bolt connection

◆ Low consumption, energy saving, environmental protection

◆ The output is 20-30% higher than that of domestic mills of the same type

◆ Finished mesh: 80-600 mesh (stepless adjustment)

When the Raymond mill is working, the materials to be pulverized are fed into the main machine from the feeding hopper on the side of the machine casing. Relying on the grinding roller device suspended on the main machine’s plum blossom frame, it revolves around the vertical axis and rotates itself at the same time. Due to the centrifugal force during rotation, the grinding roller of the Raymond mill swings outward and presses against the grinding ring. The shovel scoops up the material and sends it between the grinding roller and the grinding ring, and the purpose of crushing the material is achieved due to the rolling and rolling of the grinding roller.

After the Raymond mill grinds the material, the fan blows the wind into the main casing, blowing up the powder, and sorting it through the analyzer placed above the grinding chamber. The materials with excessive fineness fall into the grinding chamber for regrinding, and the fineness meets the specifications and enters the cyclone collector with the wind flow, and is discharged through the powder outlet after collection.

Performance advantage

● Strong systematic, high screening rate
The whole machine is a three-dimensional structure, with small footprint and strong systemicity. It can form an independent production system from rough processing of raw materials to transportation to milling and final packaging. The fineness of the finished powder is uniform, and the sieving rate is as high as 99%.

● Smooth transmission, high wear resistance
The transmission device of the machine adopts a closed gear box and pulley, and the transmission is stable, and the operation is reliable. The core components are made of high-performance wear-resistant materials, which have high wear resistance and save costs.

● Easy to control and easy to maintain
Using a centrally controlled electrical system, the workshop can basically realize unmanned operation. The electromagnetic vibrating feeder is used for feeding, which is continuous and uniform, easy to adjust, saves fuel and electricity, and is easy to maintain.
