How to make raymond mill get more fineness in the process of grinding materials?

1. Attention to abrasive materials

Many users believe that raymond mill is suitable for grinding some hard ores and minerals, but some fibrous adhesives can not be processed. The working principle of raymond mill is that the material can be grinded by the rotation of the roller and the rolling pressure between the grinding rings. Once the grinded material contains fibers and some soft and sticky ingredients, it will be bonded into cakes and can not be blown by the air flow from the fan. If it is not put into the analyzer, it will directly affect the output.

2. Note of material moisture content

Material moisture content must be prudent, raymond mill equipment requires moisture content of no more than 6%. If it exceeds this standard, even if grinded into powder, it is not easy to be blown up by the wind and can not enter the analyzer to select powder. In this case, the material has been grinding in the grinding chamber, but the product powder can not come out, and the output will be very low. Only by keeping the material dry, will the production of raymond mill be guaranteed.

3. Attention to feed size

The feed size of mineral raymond grinding is better between 8 and 30 mm, and some finer materials can also be processed. However, some users think that the finer the feed, the higher the output. This view is also a big misunderstanding. Raymond mill in the production process, the granular material will be lifted by the shovel knife, and then rolled into powder, which has nothing to do with the size of the material, will not say that the feed fineness is higher than the output.

How to make raymond mill get more fineness?

The higher the processing fineness of some materials, the greater the economic value. As a result, some users will increase the fineness of the material as much as possible in order to obtain greater economic value when they are used in raymond mill. But the processing ability of raymond mill is limited, how can we give out the fineness of the powder?

Raymond mill powder fineness increased to a certain extent, it is not impossible, such as reducing feed size, reduce the fan flow or reduce the speed of the main engine, can improve the powder fineness, but will cause the decline in production, we should be careful to use in actual production.

If you want to process the material with high fineness, you can switch to other equipment, such as high-pressure grinding mill. The fineness of the equipment can reach the highest level, which is much higher than raymond mill.

Raymond mill in the process of grinding materials

There are many kinds of ore material can be processed by the raymond mill. Raymond mill has a high market share which has always been trusted by customers. It can be said that raymond mill is commonly used in ore grinding. In the process of grinding materials, a type of raymond mill with more than 600 meshes is commonly used. So, what are the main characteristics of this type raymond mill?

In the different industries, each material can be selected according to its use value and development of grinding granularity. The required processing fineness is also different. Processing more than 600 meshes of materials is a common particle size in ore grinding. Therefore, the application efficiency of raymond mill is very high and in-process. Raymond mill is also widely used in the chemical industry, building materials and other industries.

In the process of processing ore materials, in the process of selecting suitable grinding equipment according to different materials, the operation needs reasonable control current to achieve good use effect. The use effect of raymond mill which processes more than 600 meshes is more incomparable than that of other grinders. According to certain production technology, mining. Convenient and reliable equipment is the key to ensure production.

Raymond mill has good grinding effect when processing more than 600 meshes of materials. In the whole grinding production line, a self-contained production system has been formed from block to finished molecule, which has the characteristics of small floor area and strong performance. Compared with other large floor area grinding equipment, raymond mill is more suitable. In combination with other ore processing equipment, it is a common ore grinding machine in ore grinding production line.

How to control a raymond mill better?

If you want to improve the output and quality of raymond mill, you need to control and set up the operation of each part. A good plan can directly increase the output of raymond mill. Here's how to better control raymond mill.

1. Particle size control of grinding materialsif the ore in the feed contains a certain amount of large slab aggregate and debris, a 40 mm grille is specially set at the feed port, and a vibrating screen is set to screen out the debris, so as to prevent the massive material from entering the mill, resulting in the instability of the abrasive layer vibration jump and stop.

2. Setting of raymond mill inlet and outletthe grinding system of raymond grinder is the core of the whole production line. The upper side inlet of ordinary raymond grinder is prone to blockage due to the excessive moisture content of raw materials. The feed inlet can be changed to the feed of the central screw conveyor to ensure the smooth feeding of clinker.

3. Design of hot air systemin order to ensure stable heating, effective regulation and cost reduction of fluidized bed furnace, circulating air system can be set up, and electric high temperature regulating valve and cold air valve can be installed on the outlet pipe of hot blast furnace. In order to effectively mix hot air with circulating air and cold air in fluidized bed furnace.

4. Production process controldcs control system is used to centralize and monitor the whole process of grinding system, product conveying storage and fluidized bed furnace combustion system. The system adopts modular structure, easy operation and modification of program, fast transmission speed, simple and intuitive interface display, reliable operation and improved productivity.
