The main types of mills of Henan Yuhong company mainly include Raymond mill, MTW European trapezoidal mill, ultra-fine powder mill and high waist suspended roller mill.

Characteristics of Raymond Mill：

Simple process and strong independence.

Three dimensional structure, small floor area, strong completeness, from block material to finished powder, it forms an independent production system.

Uniform fineness and convenient maintenance.

The fineness of the finished powder is uniform, and the screening rate is 99%, which is difficult for other milling equipment. The electrical system adopts centralized control, and the grinding workshop can basically realize unmanned operation, and it is convenient for maintenance.

High wear resistance and reliable operation.

Important parts are made of high-quality steel, wear-resistant parts are made of high-performance wear-resistant materials, the whole machine has high wear-resistant performance, and the transmission device adopts closed gearbox and pulley, which has stable transmission and reliable operation.

Pollution reduction.

The bellows and air duct are changed from the original horizontal bottom to 30 degrees inclined to the center to ensure that the bellows and air duct are always unblocked, and the pollution to the surrounding environment is eliminated or reduced while collecting ultra-fine powder.

MTW European trapezoidal mill：

Bevel gear drives integrally, with low energy loss and high efficiency.

Internal thin oil lubrication system, advanced and reliable.

Curved air duct, small air loss and good material fluidity.

Special grinding roller and ring structure design, curved surface replaceable blade, so that the grinding efficiency is improved and the use cost is reduced.

The particle size of the finished product is adjustable and controllable, and the powder separation efficiency is high.

No resistance air inlet volute (small observation door without vortex).

Humanized design and easy operation.

Pay attention to the concept of environmental protection.

Characteristics of ultra-fine powder mill：

1. High efficiency and low consumption

With the same fineness of materials, power and finished products, the output is 40% higher than that of air flow mill and stirred mill.

2. High safety operation

There are no rolling bearings or screws in the grinding chamber. There is no problem that the bearing, its seals and vulnerable screws are easy to loosen and damage the machine.

3. Long service life

The fineness of materials and finished products is the same, and the service life of worn parts is longer than that of impact crusher and Turbine Crusher, which can generally reach more than 1 year.

4. Superfine powder processing

The fineness of the superfine grinding product can reach D97 ≤ 5 at one time μ m。 The blade of the traditional mill blade wears quickly. The blade is an integral blade. After the blade is worn, the blade needs to be replaced as a whole, which wastes materials and increases the downtime for replacement. MTW series European grinding blade adopts high wear-resistant alloy material at the edge, which has a long service life. When replacing, only the blade part needs to be replaced, which improves the utilization rate of materials. In addition, with the traditional plane blade, the materials are stacked on a layer after being shoveled, causing serious wear in the middle of the grinding roller and grinding ring. The curved blade can guide the materials to the facade, so that the upper, middle and lower parts of the grinding roller and grinding ring can be ground, making them wear evenly. At the same time, it also increases the effective working area, thereby increasing the output.

5. The particle size of the finished product is adjustable and controllable, and the powder separation efficiency is high:

The speed of the analyzer is controlled by frequency conversion, which makes the speed more accurate and the fine material sorting effect better; The efficiency of isolated cyclone powder collector and powder separation is greatly improved. The isolation structure is adopted between the inner cylinder and the mixed gas powder flow, which can effectively improve the efficiency and accuracy of powder separation.

6. No resistance air inlet volute (small observation door without vortex):

The inner surface of the inner door panel of the observation door of the air inlet volute of the traditional mill protrudes outward and is not on the same plane as the inner surface of the air inlet volute, which is easy to produce eddy current effect and increase the energy consumption of the system. MTW series European mill adopts the inner surface of the internal door plate and the inner surface of the air inlet volute on the same curved surface, which can effectively avoid the vortex effect.

7. Humanized design and easy operation:

European mill not only adopts many advanced structures inside, but also adopts beautiful arc structure design in appearance, which makes the whole machine more humanized and reduces unnecessary damage caused by workers during operation.

8. Pay attention to the concept of environmental protection.

Characteristics of high pressure Overhang roller mill：

1. Unique design. In the grinding chamber of the main machine, a 1500kg-2000kg pressurizing device is designed on the upper part of the plum blossom frame. Under the same power, the output is increased by 10-30%, the grinding pressure of the grinding device on the material is increased by 800-1500kgf, and the fineness of the finished product can reach 300-1000 mesh at most.

2. Materials have strong applicability, and can be used for various materials with Mohs hardness below 9.3.

3. The dust removal effect fully meets the emission standards stipulated by the national environmental protection department.

4. The roller grinding device adopts high-quality and efficient processing technology, and the overlapping multi-stage seal ensures good sealing effect.

5. The long replacement cycle of grinding roller and ring eliminates the disadvantage of short replacement cycle of vulnerable parts of centrifugal crusher.

6. The grinding device adopts overlapping multi-stage seal, which has good sealing performance.
