MTW European version mill: Cohesion technology is mature and stable

We know that high standard manufacturing process can effectively prolong the service life of gears and reduce the difficulty of maintenance.

Therefore, we choose spiral bevel gears with high accuracy (accuracy greater than grade 5). The gear engagement area is stable, the operation is more stable, and the noise is lower. Among them, the big gear is made of cast steel ZG35SiMn, which is quenched and tempered; The pinion is made of 20CrMoTi forging, which is quenched, tempered, heat-treated and carburized on the surface. The big and small gears are paired to check the contact rate.

The new bevel gear overall transmission has a more compact structure, reduces the transmission chain, and significantly increases the productivity and efficiency by 20% under the same power consumption.

2. Thin oil lubrication: time-saving, stable and reliable

The three driving parts of the mill (main shaft system, powder concentrator system and fan system) are all brand-new lubricated with thin oil, which is a revolution in the field of pendulum mill. The service life of the bearing system has been greatly improved. At the same time, the oil change period is about 4 months, and the maintenance cost has been greatly reduced. Take 175 European version mill as an example, about 30000 to 50000 yuan of butter can be saved every year.

3. Supporting components: new technology, extraordinary experience

Fan: integral steel frame base, no dust leakage soft connection, petal type air regulating valve, air-cooled cooling device;

Frequency conversion hanging cage type powder concentrator: frequency conversion control, fineness adjustable and controllable;

Siemens motor: big brand, high configuration, more energy saving.

technological process

The materials stored in the raw material warehouse are crushed by the crusher, then lifted to the regulating silo by the elevator, and then sent to the European version mill host through the electromagnetic vibration feeder for grinding. In this link, the iron remover will remove the iron containing foreign matters to ensure the internal safety of the host. The materials are crushed inside the mill by mutual rolling and grinding of the grinding roller and the grinding ring. The crushed materials are blown to the powder concentrator for separation under the action of the wind. The sorted qualified materials enter the cyclone collector through the pipeline for collection, and are output by the discharge valve as finished products. The materials that do not meet the fineness requirements return to the host machine for grinding again. The milled finished products are lifted to the finished product tank for storage through the elevator.

The whole air flow system of the European plate mill is closed and circulates under negative pressure. Excess gas and fine powder are sent to the dust remover for filtering through the pipeline, the dust is collected by the dust remover, and the residual gas is discharged after purification, effectively protecting the environment.
