Calcium oxide, commonly known as quicklime, is a chemical product obtained by calcining limestone. Calcium oxide is widely used in steel, pesticide, medicine, desiccant, food tanning and dehydration of alcohol. Calcium oxide is calcined into lumps, commonly known as lump ash. In its downstream applications, it usually needs to be processed into powder and packaged for sale. So, what kind of mill is used for calcium oxide production? Guilin Hongcheng, as a manufacturer of lime grinding mills, will give you specific analysis and answers today.

Calcium oxide production equipment mainly includes: ball mill, ultrafine mill, Raymond mill, vertical mill, jet mill, etc. Each of these models has its own characteristics. According to a company's flagship product and market, choose the kind of equipment that is selected.
1. Ball mill: Extensive type product, characterized by high output, low loss and simple operation. But the noise exceeds the standard, it takes up a lot of space and the cost is high. Generally, environmental protection is not acceptable, and the suitable fineness is below 200 mesh. The production process also reduces the calcium oxide content.
2. Ring roller ultra-fine grinding: crushing and grinding that meets general ultra-fine requirements. Features: The output of a single machine is small. It is suitable for deep processing of general requirements. The fineness is between 800 and 1200 mesh.
3. Raymond mill: The most traditional mill, which belongs to coarse grinding equipment. It is the most cost-effective device among many devices. The HC series lime Raymond mill produced by Guilin Hongcheng has the following advantages:
(1) High reliability
(New technology) Plum frame and vertical swing grinding roller device, advanced and reasonable structure. The machine has very little vibration, low noise, stable mechanical operation and reliable performance. Through the practical application in the market, excellent social and economic benefits have been obtained.
(2) High efficiency and energy saving
The material processing capacity is larger and the efficiency is higher in unit grinding time. In the case of the same total power as the R-type mill, the output has increased by more than 40% year-on-year, and the unit power consumption cost has been saved by more than 30%. It is a real high-efficiency and energy-saving mill product.
(3) Environmental protection
The residual air outlet of the mill is equipped with a pulse dust collector, and its dust collection efficiency has reached 99.9%. All positive pressure parts of the main machine have been sealed, basically realizing a dust-free processing workshop.
4. Vertical mill: Vertical mill is an ideal large-scale grinding equipment. High cost and low maintenance. It can be used from coarse powder to ultra-fine powder. The fineness is from 200 mesh to 2500 mesh. Large investment, generally large enterprises can choose.
(1) Low comprehensive investment cost
Integrating crushing, drying, grinding, grading and conveying, the process flow is simple, the system equipment is less, the structure layout is compact, the floor area is small, only 50% of the ball mill, it can be arranged in the open air, and the construction cost is low, directly reducing the cost of the enterprise investment costs.
(2) High grinding efficiency
The grinding efficiency is high and the energy consumption is low. Compared with the ball mill, the energy consumption is 40%-50% lower; the stand-alone production capacity is large, and the off-peak electricity can be used.
(3) Easy maintenance and low operating costs
The grinding roller can be turned out of the machine by a hydraulic device, and the replacement of the roller sleeve liner and the maintenance of the mill have a large space, and the maintenance operation is very convenient; the grinding roller sleeve can be turned over for use, which prolongs the service life of the wear-resistant material; Load the cloth, and the mill can be started without load to avoid the trouble of difficult start-up; the wear is low, and the grinding roller and the grinding disc liner are made of special materials, which have a long service life.
(4) Stable product quality
The material stays in the mill for a short time, which is easy to detect the particle size distribution and chemical composition of the product, reducing repeated grinding, and the product quality is stable; the product particle shape is uniform, the particle size distribution is narrow, the fluidity is good, and the product adaptability is strong; the product The iron content is very small, and the mechanical wear iron contained in it is easy to be removed. When used for grinding white or transparent materials, the product has high whiteness and purity.
(5) High reliability
The grinding roller limit device is adopted to avoid the violent vibration caused by the material breaking during the working time of the mill. Adopting a new grinding roller sealing device, the sealing is more reliable, and there is no need for a sealing fan, which further reduces the oxygen content in the grinding mill and has better explosion suppression performance.
(6) Environmental protection
The entire system of the vertical mill has small vibration and low noise; the whole system is sealed and operates under full negative pressure, and there is no dust spillage, which can basically realize a dust-free workshop; vertical mill technology and equipment are new technologies for energy saving and consumption reduction advocated by the state, which is conducive to improving the quality of enterprises. Competitive strength in the field of powder industry in the region and even in the whole country.
(7) High degree of automation
It adopts a fully automatic control system and can realize remote control, which is easy to operate, easy to maintain, and reduces labor costs.
For the production of calcium oxide by the above various equipment, the auxiliary equipment must be selected accordingly, and the conveyor, hoist and feeder must be strictly sealed. Prevent a large amount of natural wind from entering to affect the calcium oxide content, and the remaining products must be cleaned up before each stop of processing, so as to prevent calcium oxide from absorbing moisture in the air under static conditions and becoming calcium hydroxide mixed with serious products to affect the quality of calcium hydroxide. As a manufacturer with rich experience in the production of calcium oxide mills, the ring roller mills, Raymond mills, vertical mills and other equipment produced by Hongcheng are favored by lime deep processing enterprises.
