Calcium hydroxide production line industry solutions

The high specific surface calcium hydroxide production line designed and manufactured by our company is a new type of equipment and new type of calcium hydroxide specially developed for desulfurization conditions. It is mostly used to replace Minnesota for flue gas desulfurization. Its specific surface area is >40 square meters/g (the specific surface area of ordinary calcium hydroxide is 15 square meters/g). Due to the advantages of high specific surface area, the combination efficiency and connection speed of calcium base and sulfur are greatly improved. With a large number of applications in the flue gas desulfurization process of the coking industry, it can completely replace the sodium-based desulfurization agent – Minnesota. It has the advantages of lower price of desulfurization agent and easier handling of desulfurization ash. It greatly reduces the cost of desulfurization, and is widely recognized and praised by enterprises using it.

In addition, in the desulfurization industry, our company has follow-up production equipment such as “column desulfurizer” and “carbon dioxide adsorbent” for calcium hydroxide follow-up products. It can meet all-round desulfurization needs.

A calcium hydroxide production line for the desulfurization industry would involve a few additional steps compared to a standard calcium hydroxide production line. Here is an overview of the production process:

Limestone quarrying: As with a standard production line, the first step is to extract limestone from a quarry.

Calcination: The limestone is then heated in a kiln to produce calcium oxide (quicklime).

Slaking: The quicklime is then mixed with water in a process known as slaking to produce calcium hydroxide.

Milling: The calcium hydroxide powder may be further processed by milling to achieve a finer particle size, which can improve its performance in the desulfurization process.

Quality control: Throughout the production process, quality control measures should be in place to ensure that the calcium hydroxide produced meets the required specifications for purity, particle size, and other properties.

Blending and packaging: The final step is to blend the calcium hydroxide with any additives needed for the desulfurization process, such as activated carbon or other sorbents. The mixture is then packaged into bags or bulk containers for distribution to customers.

In addition to the production line, a desulfurization system would also be required to use the calcium hydroxide product. The desulfurization system typically involves injecting the calcium hydroxide into a flue gas stream to react with sulfur compounds, producing calcium sulfite and calcium sulfate. The resulting solids can then be removed from the gas stream using a particulate control device.

The building materials industry is generally different from the industrial use of calcium hydroxide in terms of purity and other indicators. It is mostly used in the manufacture of putty powder, paint and other products.

Enterprises generally pursue whiteness, production capacity and digestibility (for example, traces of calcium oxide beyond the threshold cannot exist in calcium hydroxide.). For this reason, our company has a calcium hydroxide production line specially designed and manufactured for such customers in the building materials industry. In order to better provide to this part of customers.

The Calcium Hydroxide Production Line is used in the building materials industry as a component of cement, mortar, and concrete. The production process of calcium hydroxide for building materials typically involves the following steps:

1. Limestone calcination: Limestone is the primary raw material used to produce calcium oxide (CaO), which is the precursor to calcium hydroxide. The limestone is typically heated in a kiln to a high temperature to drive off carbon dioxide (CO2) and produce calcium oxide.
2. Slaking: The calcium oxide is then mixed with water to produce calcium hydroxide. This process is known as slaking or hydration, and it generates heat due to the exothermic nature of the reaction.
3. Purification: The calcium hydroxide may be purified to remove impurities, such as magnesium and aluminum, which can affect the quality of the final product.
4. Drying: The purified calcium hydroxide may be dried to remove excess water and to improve the flowability of the powder.
5. Milling: The dried calcium hydroxide is then milled to achieve the desired particle size distribution. The particle size distribution can affect the reactivity and workability of the final product.
6. Packaging and storage: The final product is typically packaged in bags or bulk containers and stored in a dry environment to prevent moisture absorption and to ensure product quality.

Overall, the Calcium Hydroxide Production Line for the building materials industry requires high-quality, low-impurity calcium hydroxide products with a specific particle size distribution. The production line may include additional steps, such as purification, drying, and milling, to achieve these requirements.

For pelletizing or sintering needs of steel mills. Our company has designed and developed a large-capacity calcium hydroxide production line with a maximum capacity of 60T/h. And aiming at the fact that the requirements for calcium hydroxide finished products are relatively low in the pellet sintering process, an automatic calcium hydroxide production line with lower T energy consumption and higher cost performance is provided. Its equipment investment is only within 50% of the standard calcium hydroxide production line.

An optimal solution for the requirement of calcium hydroxide for pellet sintering, which is different from ordinary ones, is given.

A large-capacity Calcium Hydroxide Production Line is designed to produce high-quality calcium hydroxide products on a large scale. The specific design and capacity of the production line will depend on the requirements of the application and the production volume.

The key components of a large-capacity Calcium Hydroxide Production Line typically include:

Raw material storage and handling: The raw materials, such as limestone, are typically stored in silos or other storage facilities and transported to the production line via conveyors or other material handling equipment.

Calcination: The limestone is heated in a kiln to produce calcium oxide.

Slaking and purification: The calcium oxide is mixed with water to produce calcium hydroxide, and the resulting slurry is purified to remove impurities.

Drying and milling: The purified calcium hydroxide slurry is typically dried and milled to achieve the desired particle size distribution.

Packaging and storage: The final product is typically packaged in bags or bulk containers and stored in a dry environment to prevent moisture absorption and to ensure product quality.

To achieve a large production capacity, the Calcium Hydroxide Production Line may be designed with multiple processing units operating in parallel or with continuous processing equipment to minimize downtime and maximize production efficiency. The production line may also be automated to improve process control and reduce labor costs.
