Types of Hydrated Lime Production Line

A hydrated lime production line refers to the complete set of machinery used at an industrial scale for the manufacture of hydrated lime from quicklime, which in turn is produced from limestone. A hydrated lime production line consists of several large-scale machines, each performing specific tasks with utmost precision and efficiency.

The main types of hydrated lime production lines as indicated by the primary materials are as follows:

  • Limestone Crusher: As the name suggests, this machine's primary job is to crush large pieces of limestone into small ones. One of the most popular kinds of crushers used in the industry to make limestone smaller is the jaw crusher, but others include rotary crushers or impact crushers. A crusher equipped with a screening device can help separate crushed limestone by size and ensure only appropriate pieces enter the next phase of the operation.
  • Lime Kiln: This is perhaps the most important piece of equipment in a hydrated lime production line. A lime kiln is a large-scale oven that heats crushed limestone to over 900 degrees Celsius to produce quicklime (calcium oxide) through a chemical process called calcination. There are several types of lime kilns, such as rotary kilns, shaft kilns, and solar kilns. The choice of lime kiln in a hydrated lime production line will depend on several factors, such as the scale of production, the quality of lime required, and the environmentally sustainable practices of the business. For instance, a rotary kiln hydrated lime production line will produce both quicklime and hydrated lime, as it usually comes equipped with a hydrated lime classifier.
  • Quicklime Hydrator: This is the machine that adds water to the quicklime to produce hydrated lime. The hydrated lime production line will not be complete without a quicklime hydrator, which comes in various sizes and models. The choice of hydrator will depend on how much hydrated lime is required by the enterprise. In some productions, the hydrator is also called a slaker.
  • Hydrated Lime Sifter: This is a device that separates hydrated lime by particle size. It ensures that only the right particle sizes are graded and packed for shipment to customers. In many cases, it is stored as a powder.
  • Packing Machine: The final product of the hydrated lime production line is of little use to the consumer unless it is in convenient, small-sized packages that can easily be transported and stored. The packing machine does precisely this. It can pack hydrated lime in bags, cartons, or barrels. The packing machine now works seamlessly with smart inventory systems to provide customers with products in the exact manner they desire.

How to choose proper hydrated lime production line

Both quality and the quantity of hydrated lime production line can be ensured by the following factors. The main apparatus needed in a quicklime production line are a stone picker, feed conveyor, crushing machine, feeder for a lime kiln, lime vertical kiln or lime rotary kiln, cooler, hydrated unslaker, hydrator, air classifiers, packing machine, and powder storage. Other than the mentioned primary lime production machinery, there are many other supports and satellites required for a line to function efficiently like a conveyor belt sorting stones, a feeder that will supply fuel to the kiln, a cooler conveyor belt, and a classifier to segregate the material according to different grades. All of these small but essential apparatus make it possible to have an uninterrupted flow of hydrated lime that can be packed and used in industries.

While looking for a factory or supplier, always check the features, capacity, and types of fuel used by the production line. If the production line uses solar energy along with fossil fuel for burning the limestone, it will be a sustainable option that can be used in eco-friendly industries. The carbon emissions of the kiln should be stated clearly so that people understand the negative or positive implications of using that particular kiln. Many modern factories have shifted to totally enclosed production lines where there are no leakages of hydrated lime or any other chemical in the environment. Air filters help to keep the air clean and all the materials are usually stored in silos which does not allow any material to escape into the air. Silos are also easy to clean and maintain. Other than quality and quantity, the sustainability of a production line and its ecological impact on the surroundings is essential knowledge for buyers.

In addition to the above factors, the buying of a lime production line will depend on the market demand for the lime or hydrated lime product. The larger the production capacity, the more burning chambers there will be in a kiln, which will increase the output of hydrated lime. For example, a 5-ton lime vertical kiln may have two to three burning chambers, but a 20-ton kiln may have six to seven chambers. Similarly, the daily output of a lime production line will increase dramatically if the capacity of the machine increases. While investing in such a machine, it is vital to study the market demand and understanding so that it can fulfill commercial requirements. The cost production of the limestone on a large scale will also depend on the capacity of each machine. It is, therefore, important to understand the working of the entire lime production line from the introduction of the raw material to the packing of the final product. The more familiar one is with the functioning of the production line, the easier it will be to make a profitable investment.
