HLM series vertical mill is a large-scale advanced,high-efficiency and energy-saving grinding product developed by 118 Technology Group using the world's advanced material bed grinding and partial external circulation technology,combined with more than 40 years of experience in mill production and manufacturing of 118 Technology Group.Grinding,grading,drying and conveying are integrated,with independent intellectual property rights,and the core technology and economic indicators have reached the international advanced level.
The main motor drives the grinding disc to rotate through the reducer, and the fixed grinding roller rotates along the raceway of the grinding disc. The material falls from the feeding port to the center of the grinding disc. Under the action of centrifugal force, the material moves from the center of the grinding disc to the edge at a constant speed. When passing through the grinding raceway, it is crushed by the grinding roller. The grinding force is provided by the hydraulic loading system. The material is directly crushed, and the fine-grained material is squeezed to form a material bed for intergranular crushing.
Drying and grinding are carried out at the same time. The primary hot air enters the surrounding of the grinding disc evenly through the air ring, and the pulverized materials thrown out tangentially from the grinding disc after grinding are dried and transported to the upper powder separator. Under the action of the rotor blades, Coarse particles return to the grinding table for grinding (internal circulation), and the qualified fine powder is milled together with the airflow, and is collected by the system powder collector, which is the finished product.
The powder sorting machine with dynamic and static structure has higher efficiency.
The hydraulic maintenance device can easily turn the roller out of the machine, and the replacement of the roller sleeve and the main-tenance of the roller are convenient and fast.
The iron content in the product is very small, which effectively ensures the product whiteness and purity of the material.
The grinding roller and grinding disc are made of special materials, which can flexibly adjust the grinding pressure and are efficient and energy-saving.
By adjusting the hotair temperature, the drying requirements of materials with df ferent humidity can be met, and the maximum drying humidity of materials can be met as high as 15%.
No dust spillage, reliable sealing, and dust removal efficiency as high as 99. 9%.
