XZM Ultrafine Mill

XZM Series Ultrafine Mill

XZM Ultrafine Mill

Zenith XZM Series Ultrafine Mill is widely used for micron powder producing. The output size can reach 2500mesh (5um). It is suitable to grind the material with middle and low hardness, moisture below 6%, and the material should be non-explosive and non-flammable, such as: calcite, chalk, limestone, dolomite, kaolin, bentonite, steatite, mica, magnetite, iolite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate ore, potassium ore pumice, etc. The size of the finished product can be adjusted between 325-2500 mesh. For almost 30 years, Shanghai Zenith has being specializing in all facets of grinding mill design and maintenance. XZM series ultrafine mill is specially designed for super fine powder grinding. Now it's growing more and more popular with its reliable technology and perfect after-sale services.

Treatment of powder phenomenon in ultrafine grinding mill

Over the powder is generally qualified powder grinding particles have not been screened out, and back to grind to continue to accept a phenomenon of grinding, over the powder phenomenon will directly lead to a warehouse of fines, grinding quality decline. The occurrence of the powder phenomenon is usually related to the material flow rate and the quantity of fine powder in the mill, so we will be more targeted when we solve the powder phenomenon. Ultrafine mill in the operation also often occurred in the phenomenon of powder, then, in the ultrafine grinding occurs when the phenomenon of powder to deal with it? Let's explore.

1. Strengthen the internal ventilation of the mill

Good ventilation can be carried out in time to produce fine powder, effectively eliminate the cushioning effect of fine powder. Good ventilation can also allow the water vapor in the mill to be taken away in time, can effectively reduce the occurrence of adhesion phenomenon, but also make the sieve hole is not easy to plug. Strengthening the ventilation in the mill also helps to reduce the temperature of ultrafine grinding and greatly improve the production of ultrafine grinding.

2. Adding grinding aid

Grinding aids can be effectively adsorbed on the surface of the material, so that the material between the bond is not easy to occur. Grinding aids can also be adsorbed between the cracks in the material particles, effectively weaken the "healing effect", speed up the flow of materials in the mill, reduce the material in the mill stay time, can effectively reduce the occurrence of powder phenomenon.

3. Selection of Liner

Ultrafine grinding liner for grinding effect plays a very important role, if the use of spiral liner or groove lining plate and other new liner can effectively reduce the phenomenon of excessive powder, because these new liner have a good selective grinding effect.
