Annual 100 Kilotons Natural $k$

Material: Gypsum

Daily Operation: 10h

Input Size: ≤35mm

Finished Product: 325mesh

Equipment: MTW138 Grinding Mill

 

 

Project Background

The customer has been doing gypsum industry for a long time, and has used the traditional pulverizer. Later, when he attended the exhibition, he saw ZENITH. After understanding the European version of this product, he finally chose MTW138.

 

Advantages

1.       Energy Saving & Environmental Protection

MTW European Grinding Mill adopts volute design without resistance, which made tangential airflow more smooth and energy consumption lower.

 

2.       High Quality of Finished Product

The mill adopts high-efficiency cage-type powder selecting machine, which can select powder with high precision and efficiency, and prevent the phenomenon of “running coarse powder”.

 

3.       Longer Service Life

The use of thin oil lubrication which is better than traditional oil. The low oil temperature can effectively extend the bearing’s life.

 

4.       Lower Investment

In combination with the requirements of customers, MTW Grinding Mill is used to replace the traditional one, so as to reduce the investment cost in the early stage.

This type grinding milling machine 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, potassiumore pumice, etc

 

 

$k$ Working principle 

 

 1)Raw material which has been crushed to the size specified is elevated into a hopper from which the stuff is loaded. And then through the vibrating feeder ,the materials will transferred evenly and continuously into the grinding milling machine grinding chamber for powder-processing. After this,the ground stuff is carried by the air from the blower into the classifer for regrinding.The set's airflow system is closely sealed up and circulated under the condition of negative and positive pressure.

2) The gypsum grinding plant is driven by rotation of the central axle through decelerator ,with the up end of the axle connecting to a quincunx-rack upon which the grinding equipment is fixed. The whole set equipment turns together with the axle along the grinding ring while the rollers rotate driven by the fractional force .A set of shovel are installed at the lower end of the quincunx-rack.While turning together with the rollers ,the shovels shed the stuff onto the gap between the rollers and the ring ,and that's where the stuff layer forms .The rotating rollers ,while turning together with the ring ,grind the stuff layer into powder.

 

3) The turning speed of the impeller can be adjusted to the requirement of the fineness of powder products .

 

4)$k$ plays an important role in ensuring the function of the grinder . As the high-speed revolving air current mixed with ground stuff is flown into the cyclone-collector ,the ground stuff is separated from the air-current
