Ultrafine Desulfurized Limestone Vertical Roller Mill Calcium Carbonate Powder Mill

 Desulfurized Limestone Vertical Roller Mill, Ultra-Fine Vertical Mill, Calcium Carbonate Powder Mill

Description

Quicklime, also known as quicklime, is mainly composed of calcium oxide. All natural rocks mainly composed of calcium carbonate, such as limestone, chalk, and dolomitic limestone, can be used to produce lime. Coastal areas use shells as raw materials and burn them into shell ash, which is used as quicklime.
Quicklime powder has a wide range of uses. It can be used for lime mortar masonry or plastering engineering, as well as for road base and ground of various buildings. Not only in construction, but also as a filler, lime powder is an indispensable material in many fields. Vertical mill has the characteristics of high yield, high concentration, high grinding efficiency, simple maintenance, and convenient maintenance. It is the best choice for processing quicklime.

How to choose a suitable quicklime vertical mill?
1. The particle size, humidity, viscosity, and hardness of limestone vary, so when choosing a vertical limestone mill, consideration should be given. Of course, the model of the vertical limestone powder mill equipped is also different, which becomes an important parameter for the selection of vertical limestone powder mills.
2.There are many models of vertical mills, and there are also many models that can process limestone powder. Some grinding machines have high production capacity but high losses, while others have low production capacity but save energy. For different needs, only suitable ones are good. This mainly depends on the production capacity demand of quicklime powder for selection.
3. Different fields have different requirements for the fineness of quicklime powder. More importantly, only by selecting the right vertical grinding equipment can the fineness of quicklime powder suitable for this field be produced. The fineness of the finished product does not meet the requirements, and the output is large, which is of no use. Therefore, it is also important to choose a vertical mill based on the required powder fineness, which is also important for the selection and configuration plan of limestone vertical mills.

Limestone Vertical Mill Working principle:

The electric motor drives the grinding disc to rotate through the 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 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 wind ring 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 the qualified fine powder is discharged with the airflow, Collecting in the powder collection device is the product. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.

Main features of the product
1. Efficient and energy-saving:
(1) High grinding efficiency, low energy consumption, compared to ball mills, energy consumption is 40% -50% lower;
(2) Single machine production capacity is large, and low valley electricity can be utilized;
(3) Vertical grinding technology and equipment are vigorously advocated as new energy-saving and consumption reducing technologies, which are conducive to enhancing the competitive strength of enterprises in the powder industry in this region and even nationwide;
2. Easy maintenance and low operating costs:
(1) The grinding roller can be flipped out of the machine using a hydraulic device, and the replacement of the roller sleeve liner and the maintenance space of the mill are large, making the maintenance operation very convenient;
(2) The grinding roller sleeve can be flipped over for use, extending the service life of wear-resistant materials;
(3) Before starting up, there is no need to place fabric on the grinding disc, and the mill can be started without load, eliminating the difficulty of starting up;
(4) Low wear, special materials are used for the grinding rollers and disc liners, resulting in a long service life;
(5) High degree of automation: The automatic control technology adopts Siemens series PLC from Germany, equipped with an automatic control system, which can achieve remote control and is easy to operate. The workshop can basically achieve unmanned operation, saving operating costs;
3. Low comprehensive investment cost:
Integrating crushing, drying, grinding, and conveying, the process flow is simple, the system equipment is few, the structural layout is compact, and the land area is only 50% of that of a ball mill. It can be arranged outdoors, with low construction costs, directly reducing enterprise investment costs.
4. Stable product quality:
(1) The material stays in the grinder for a short period of time, making it easy to detect the particle size distribution and composition of the product, and ensuring stable product quality;
(2) The product has uniform particle shape, narrow particle size distribution, good fluidity, and strong adaptability.
5. High reliability
(1) Adopting a grinding roller limiting device to avoid severe vibration caused by material breakage during the working time of the mill;
(2) Adopting a new type of roller sealing device, the sealing is more reliable and does not require a sealing fan, further reducing the oxygen content inside the mill and achieving better explosion suppression performance.
6. Environmental protection:
(1) The entire system of HVM vertical grinding machine has low vibration and low noise;
(2) The system is sealed as a whole, operates under full negative pressure, and has no dust leakage, basically achieving a dust-free workshop.
