Efficient Energy Saving Limestone Vertical Powder Mill For Cement Plant

Efficient Energy-Saving Limestone Vertical Powder Mill, Cement Plant Vertical Mill, Vertical Cement Mill

Description

The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are widely used as building materials and are also important raw materials for many industries. Limestone can be directly processed into stone and fired into quicklime. Lime includes quicklime and hydrated lime. The main component of quicklime is CaO, which is generally in block shape, pure white, and light gray or yellow when containing impurities.
The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are widely used as building materials and are also important raw materials for many industries. Limestone can be directly processed into stone and fired into quicklime. Lime includes quicklime and hydrated lime. The limestone processing process requires the use of crushing and grinding equipment.

Processing technology
Phase 1
Firstly, use a crusher equipment to crush large pieces of limestone.
Phase 2
After crushing, materials with appropriate particle size are sent to the European version T-shaped mill or medium speed T-shaped mill through conveyor equipment.
Phase 3
After the material enters the European version T-shaped mill or medium speed T-shaped mill, it undergoes the crushing, grading, and separation processes of the grinding equipment to obtain the finished product. In the process of producing limestone, it is best to equip it with dust removal equipment to prevent dust pollution.
Stage 4
Packaging and storage of finished materials

Technical Data

Limestone Bond Index≤13kwh/t

Working principle

The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing water are dried in the Contact process with hot gas to meet the required product moisture.

Product advantages:
1. More obvious energy-saving effect
Due to its advanced concept, simple process, and small installed capacity, the desulfurization limestone vertical mill can save 45% to 60% of electricity when grinding ultrafine limestone compared to traditional tube grinding systems.
2. High grinding efficiency
By hydraulic pressure boosting, the grinding force can be increased, thereby increasing production and improving grinding efficiency. At the same time, there is also a limiter device that only grinds the material to prevent accidental contact between the grinding roller and the grinding ring from causing equipment vibration or even wear.
3. Equipment is environmentally friendly, with low noise, less dust, and a clean operating environment

In the operation of a vertical mill, the grinding roller and grinding disc do not directly contact each other, and there is no metal impact sound of steel balls colliding with each other or hitting the lining plate in the ball mill. Therefore, the noise is low, which is 20-25 decibels lower than that of a ball mill. In addition, the vertical mill adopts a fully sealed system, which operates under negative pressure, without dust, and the environment is clean.
