SBM XZM ultrafine mill
XZM Ultrafine mill is widely used in making fine powder or micro powder, a new kind of machine for producing fineness and ultra-powder. grinding mill is mainly used for grinding the material with middle and low hardness, below 6% moisture, and the material should be non-explosion and non-flammability, 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 production can be adjusted between 325-2500 mesh.
PROJECT CASE
A mining company in India intends to produce calcium carbonate powder with fineness of 5-10 micron; required capacity is 1.0 ton per hour. They had a Raymond mill which can not meet their desired fineness. Their stone input size is 12"-14". They have a primary 16"×10" jaw crusher. Based on customer's situation, we had recommended full set of XZM221 Ultrafine mill for their solution. The mill was installed since 2009 and is running perfect in India now.
PRODUCTION PROCESS
Raw material of 12"-14" size is primarily crushed by the client's jaw crusher down to 2" and then enter into our hammer crusher PC400×300, after secondary crushing, it will be less than 0.4", and discharged to bucket elevator. The elevator sends the material to storage hopper, there’s a vibrating feeder under the hopper, and the feeder feeds material to main unit of XZM221 mill evenly and continuously.
When the material being ground in the mill, the blower blows the powder to classifier, the classifier impeller is rotating at adjustable speed which is controlled from control cabinet, as per client’s requirement, powder less than 10 micron will be separated by classifier, and bigger powder falls down, being reground over and over again. 10micron and less than 10micron powder then go to the cyclone collector with the air from blower and be collected in the cyclone collector. Powder will be discharged from the discharge valve to become the final products. The bag filter will clean the outgoing air to protect the environment.
ADVANTAGE OF SBM XZM ULTRAFINE MILL
New designing, reasonable structure, smaller size, lower energy consumption, longer service life, lower cost of spare parts, higher performance cost ratio. All technical performance has reached world leading level in ultrafine powder production industry.
SBM XZM MILL are widely applied in industries such as painting, paper, agriculture, chemical, PVC plastic, metallurgy, power supply, etc. With the increasing demand of powder making industry, SBM XZM ultrafine mill will play an even important role in modern mining industry.
SBM SCM Ultrafine Mill in India
This is a screenless pulveriser used for grinding soft to medium hard materials into super-fine powder. The industrial grinding machine has a built-in water jacket to keep down the temperature in the machine chamber.
This grinding machine is generally used for super fine grinding of food dyes, industrial dyes, vat dyes, dye intermediates, pharma drugs, chemicals etc. The feed is through a feeder screw that feeds material centrally into the machine chamber. The grinding takes place due to attrition between a high speed rotating rotor having six arms with wear resistant tips and side liners on both side of the tip and also a turbo effect. Hence this ultra fine grinding mill is sometimes referred to Turbo Mill. The annular gap plate controls the flow of materials through the mill. In other words it regulates the fineness of the materials. The powder is discharged through the bottom hopper.
