XZM Series Ultrafine Mill Price

XZM Series 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.

Ultrafine Mill Upgrade

  • (1) to improve the analyzer, increase the number of leaves, improve speed, and some also use double leaves, product fineness to 600 head;
  • (2) increase the dust collection system to reduce dust pollution;
  • (3) the use of secondary grading system, from the 325 mesh finished powder sorting out 800-1250 purpose ultrafine powder. Although some progress has been made, there are still some defects such as a smaller secondary yield, a lower efficiency, and a lower grade material.

Ultrafine mill is a professional milling machine, what is the principle of its work? Here I do some detailed explanation: Raymond grinding host, fan, pipe, dust and other parts, raw materials through the inlet into the grinding chamber inside, grinding between the grinding and grinding ring, shovel shovel material Grinding roller grinding ring between the grinding to a certain extent, the role of the wind through the material sent to the analyzer, after the analyzer screening effect, to achieve finished fineness of the material through the pipeline into the finished product unloader, Fineness of the finished product is returned to the grinding chamber for grinding until the desired fineness is achieved. This is the working principle of ultrafine mill.

Whether the grading machine can achieve the grading function well, in addition to its own structural parameters, also depends on the matching air delivery system. From the separation formula of the impeller classifier, it can be seen that the size of the separated particle size is inversely proportional to the impeller speed and is proportional to the square root of the air flow through the impeller. The traditional ultrafine mill blower matches the fan-like analyzer with a large rated air volume and a low wind pressure to meet the grading range of 80 to 325 mesh. For the target classification range of 100 to 1250, the classification range has changed greatly. Therefore, it is necessary to significantly reduce the air flow rate of the blower in order to achieve ultrafine classification. And its wind pressure should be greatly increased in order to overcome the introduction of high-speed large impeller classifier after the increase in resistance (according to our test, the 4R, 5R ultra-fine grading machine in the classification of 1250 head when the wind pressure can reach 1800 ~ 2200 Pa). From the separation of the particle size formula can be obtained to obtain a smaller grading particle size must increase the impeller speed and reduce the air volume, but also must be through the impeller air flow in the laminar flow state. The smaller the air volume and the flow rate is not easy to bring the large particles within the grinding chamber into the classification area, can reduce the pressure on the periphery of the grading wheel, more importantly, easy to make the air flow through the impeller flow laminar state, And the accuracy of the increase. A large number of experiments have shown that in order to obtain a smaller graded particle size, the effect of reducing the flow rate is often better than the effect of increasing the impeller speed. Of course, too small flow will reduce the output, it must be repeated trial, a reasonable choice to find the best process parameters (impeller speed and air volume matching).
