Overview
MTW-Z European Trapezium Mill is new product researched and developed by LIMING based on ordinary European type grinding mill. Because of more advanced idea and more reliable performance, it has been an intelligent key to the mill market.
Output size : 1.6-0.045 mm, the fineness is 0.038mm
Production capacity : 3-50T/H
APPLICATIONS
Feldspar, calcite, limestone, talc, barite, rare earth, marble, bauxite, phosphate ore, iron oxide red, dolomite, granite, bitumite, anthracite, lignite, kaolin, bentonite, gypsum.
Features
1.The power is strong and bevel gear drives overall. The transmission ratio is more accurate and transmission chain is reduced. Energy loss is reduced and efficiency is improved.
2.Both spindle drive system and fan transmission system adopt dilute oil lubrication, and the oil will be changed every 4 months. Oil exchange cycle is long and maintenance frequency is less.
3.New hanging type cage classifier makes output size adjustable and powder collecting efficiency improved.
4.The capacity reach up to 50t/h, which is superior to other grinding machines’.
5.This machine has got many national patents with advantages of stable running and reliable performance. Besides, it has got environmental protection certification as industrial product. There is little duct and noise during grinding process, which can satisfy the requirements of national environmental protection.
Working Principle
After jaw crushers break large bulky materials to smaller ones, elevators work to send materials to the hopper. Then, by electromagnetic vibrating feeders, broken materials are evenly and quantitatively sent to the grinding chamber of MTW European Grinding Mill. After grinding, materials are blown away by airflow to the powder concentrator for classifying. Under the action of the impeller of powder selector, materials which fail to meet fineness would be sent back to grinding chamber to get another grinding while qualified powders would be collected by cyclone powder collector and discharged from the bottom as finished products. And, after that, the airflow would go into the fan along with the air return duct at the top of cyclone power collector. This system adopts a closed circuit and runs under positive and negative pressure. Because materials have a certain content of moisture, heat generated during grinding may lead air evaporation or swell in the grinding chamber so that the amount of airflow increases sharply. Besides, if the feed port and joints of pipelines are not sealed well, external air may intrude the grinding mill and lead imbalance of airflow. So, SBM arranges exhaust valves at the air outlet of the fan to induce redundant air into the bag filter. After purifying, the redundant air is discharged. This arrangement can achieve both the balance of airflow and the eco-friendly production.
