Calcium hydroxide (Ca (OH) 2) is obtained by digesting calcium oxide and water. Commonly known as “hydrated lime” or “slaked lime”, the digested calcium hydroxide is a white powder, which needs to be processed into high-purity calcium hydroxide by calcium hydroxide grinding equipment. HCMilling(Guilin Hongcheng) is a manufacturer of calcium hydroxide powder production equipment. Below is a comparison of several calcium hydroxide grinding mill equipment.

Advantages of high-purity calcium hydroxide:

1. The high activity is more than 300ml.

2. The content of high-purity calcium hydroxide is more than 72%.

3. The impurity content is low. The content of silicon oxide, aluminum oxide, iron oxide and magnesium oxide is 1.70%, and the content of carbon oxide is 1.10%.

4. The harvest rate is high, up to 95.1% or more, and it can produce on a large scale.

5. It can meet the production demand of epichlorohydrin, bleaching powder and other chemicals, replace caustic soda, and save caustic soda consumption and energy.

At present, there are mainly three types of calcium hydroxide grinding mill equipment on the market to produce calcium hydroxide, which are divided into ball mill, Raymond mill and lime calcium mill. Their advantages and disadvantages are as follows:

1) Ball mill, the output is about 7 tons/h. Its advantage is that the output is high, but the product cannot be discharged when it is dry. The fineness is 200~325 meshes, and impurities cannot be removed

2) Raymond flour mill, the output is about 3 tons/h. High output, product drying fineness of 200 meshes, impurities cannot be eliminated

3) Lime calcium machine, with output of 1 ton/h. Low yield. The calcium hydroxide (lime calcium powder) is characterized by its fineness up to 400 meshes, which can eliminate impurities. The impurity content is lower than 0.1%, and the adsorption is strong.

According to the comparison of calcium hydroxide grinding equipment above, each of the three equipment has advantages and disadvantages. As a manufacturer of calcium hydroxide grinding mill equipment, HCMilling(Guilin Hongcheng) has developed a calcium hydroxide grinding mill equipment that can discharge slag based on the traditional Raymond mill. Its capacity can exceed the output of the ball mill, and has the function of removing impurities from the lime calcium mill. It can produce high-purity calcium hydroxide powder with high specific surface area, which is an ideal choice for high-purity calcium hydroxide production at present. At present, the fineness of calcium hydroxide equipment of Chinese calcium hydroxide production line manufacturers is usually 200-400 meshes, with the content of 65% – 93%. It is mainly used in electric smoke desulfurization, sewage treatment, anti pollution materials, construction and other industries. The calcium hydroxide grinding mill equipment produced by HCMilling(Guilin Hongcheng) can produce 6-20 tons of finished calcium hydroxide per hour, and the largest amount of finished calcium hydroxide can be produced by Tiantian. The particle fineness can reach 325 meshes to 1250 meshes. HCLM calcium hydroxide grinding mill produced by HCMilling(Guilin Hongcheng) occupies a small area. It integrates crushing, conveying, pulverizing, finished product collection, storage and packaging into an independent and complete production system with strong systematicness.

1. The important parts are made of thickened high-quality steel, wear-resistant parts made of high-performance wear-resistant materials, and maintenance free grinding roller assembly. The design architecture is advanced and reasonable, and the grinding ring can be replaced without disassembly. The equipment operates reliably, and the maintenance is more convenient.

2. The electric system with integrated control is adopted, and the pulse dust remover is used to collect the residual air. The dust collection rate is above 99.9%, basically realizing a dust-free and unmanned workshop.

3. The improved mill system is upgraded, with more reasonable configuration and higher output. The calcium hydroxide equipment has high fineness classification accuracy, and the particle size of the finished product can be adjusted arbitrarily within 80-1250 meshes.

4. High pressure centrifugal fan is adopted for the blower, which increases the air volume and pressure and improves the gas transmission capacity.

With the continuous improvement of the production process and technology of the calcium hydroxide grinding mill, upgrading and more intelligent, the electrified integrated system is comprehensively applied to the products, which makes the fineness, whiteness and evenness of the finished calcium hydroxide equipment more perfect, the output more and more high, the production automation more energy saving and environmental protection, and the larger and high-capacity calcium hydroxide equipment production lines will become more and more common and put into use to meet the wider use needs.
