3 Minutes to Get to Know Raymond Mill Raymond Mill Working Structure Design

Raymond mill is suitable for the grinding of Mohs hardness below level 9.3, humidity below 6% in a variety of non flammable and explosive mineral materials such as cement (clinker; students), coal, talc, quartz, feldspar, mica, slag, limestone, barite, potassium sulfate, bentonite, etc. more than 1000 kinds of material.

Raymond Mill designed the grinding roll and grinding ring into a ladder shape, which reduced the sliding speed of the material entering the grinding roll and grinding ring, thus prolonging the rolling time of the material and improving the grinding effect. Press spring with stable pressure and can play elastic coupling vibration effect is stable, the overall force device and other products compared to around 40% increase; while the elastic coupling device can reduce the vibration and noise, and avoid resonance.

Equipped with high density powder separator impeller which can improve the powder selection precision, the fineness of

the finished product can be improved by increasing the density of the blade under the condition of constant rotation speed, and the finished product can be increased by more than 50% under the same power. With high efficiency and energy-saving centrifugal fan, the efficiency of induced draft fan is improved.

The advantages and application scope of Raymond Mill In the mill equipment, the production cost of Raymond mill is the same. The three-dimensional structure saves the production line area and is similar to the design principle of the vertical mill.Raymond mill can form an independent production system from raw material rough machining to transportation to powder and packaging. The difficulty of manual work is low, and the electric system is centralized control to improve the production efficiency. Every hour to achieve 11 tons of finished powder, the screening rate of up to 99%, become a well deserved "milling machine king".

Raymond Mill's continuous improvement in its working principle and structure has become the unique advantage of high efficiency, low energy consumption, small footprint,

less investment and environmental pollution. The following Mohs hardness of seven, humidity below 6% in a variety of non flammable and explosive minerals. In order to meet the user standard of different industries, Raymond mill can control the fineness of finished products between 613 micron ~440 micron (0.613 mm -0.44 mm) by adjusting the parameters of analysis machine and fan.

1. Raymond Mill stereoscopic structure, small area, complete set of strong, from the block to the finished powder is a independent production system.

2. The fineness of the finished powder is uniform and the screening rate is 99%, which is difficult for other grinding equipment.

3. The driving device of the grinding machine adopts the closed gear box and the belt wheel, and the transmission is stable and the operation is reliable.

4. High quality steel is used in all the important parts of Raymond mill. The wear-resistant parts all adopt high performance wear-resistant material. The whole machine has high wear resistance and reliable operation.

5. the electric system adopts centralized control, the

grinding mill can basically realize unmanned operation, and the maintenance is convenient.

How to improve the structure performance of the Raymond mill?

With the continuous development of the powder industry, the market demand for ultrafine iron Raymond Mill is also increasing. As the main equipment for grinding in the powder industry of China, ultrafine grinding mill of iron ore is an inevitable trend for the development of "high reliability, energy saving, precision and automation".

Due to the problems of low fineness, high power consumption, large noise and low system efficiency, the traditional Ultrafine mill bothering the mineral processing enterprises and the equipment manufacturers of Raymond mill.

Four improvements of the structure of ultrafine Raymond mill are as follows: First, the structure of the main shaft and the plum blossom frame is conducive to stable structural transformation, so that the operation is stable.

Two. The traditional part of the analysis machine is changed into two isolation from the inside of the hanging cavity of the vertical hanging hoist, which enhances the stability and durability of the machine.

Three. in the grinding zone, the grind material is always gathered in the grinding zone effectively processing, improve grinding efficiency, but also updated the roller structure, the grinding roller and the roller shaft can be complementary in the rotation of the operation, also can make the revolution, its effect and durability.

Four. in the ventilation part, the bellows and the air duct are changed from the original horizontal bottom to 30 degrees to the center, forming a bucket to ensure that the bellows and the air duct are unobstructed and unobstructed, so that the air volume is always maintained, and the host mill is in high efficiency.
