6 - 80 t/h Capacity Limestone Vertical Grinding Mill - Used for Limestone Processing Plant

Description

Is the limestone powder vertical mill good or not?
Is the limestone powder vertical mill good or not? What is the price of one unit? Limestone powder can be used to prepare cement, lime slurry, lime paste, and coatings, which has made many entrepreneurs eager to enter the limestone powder industry. However, business opportunities are right in front of them. However, due to their lack of understanding of the production line of limestone powder vertical mills, they are hesitant. Below, Hefei Hengcheng will provide a detailed explanation of limestone powder vertical mills.

1,What is limestone?
What should be paid attention to when selecting a limestone powder vertical mill? It is necessary to understand the composition of limestone and its application in upstream and downstream fields. Industry insiders know that the main component of limestone is calcium carbonate, which is widely distributed in China due to its properties such as corrosion resistance, acid resistance, stability, etc. It is most suitable as a brick and tile adhesive and coating material.
In the process of deep processing limestone, a limestone powder vertical mill is essential.

2,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.

3, Main characteristics of limestone vertical mill
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.

Our strengths:
1. Over 15 years of experience in vertical grinding and pneumatic conveying, system research and development, and manufacturing

AAA Credit System Certificate

4. How to choose a vertical mill for limestone powder production?
Limestone powder is applied in different fields, and the requirements for the fineness of limestone are also different. When selecting a limestone powder vertical mill for the fineness requirements, ultrafine limestone powder vertical mills and general limestone powder vertical mills can be selected.
The vertical grinding of calcite adopts a three-dimensional structure, which occupies a smaller area compared to its grinding equipment. Strong completeness, independent production system from block materials to finished powder. Calcite is mainly used in industrial sectors such as petroleum, chemical, paint, and filler after being ground into powder by a grinding machine. 80-90% of it is used as a mud weighting agent in petroleum drilling.
Calcite, also known as large calcite or small calcite, is a type of calcium carbonate mineral commonly found in natural calcium carbonate. Calcite has many other uses, such as being used as a building material and also as a decoration. It usually appears as clusters of crystals, which are very beautiful and can produce many square fragments when struck. After grinding, calcite can also be used in daily chemical industries such as rubber, coatings, inks, food, textiles, and ointments. The calcite grinding machine is a specialized equipment for processing calcite, which can also be used for grinding other ore materials. It has a high usage rate in the grinding industry. The grinding products of the equipment have fine particle size, uniform texture, environmental protection and energy conservation during the working process, low carbon and low consumption, and high output.
When choosing a limestone powder vertical mill, the first thing to consider is the manufacturer. If the manufacturer is strong and has a good reputation, it is equivalent to choosing the right half of the product.
