Things You Should Know About Lime Slaker Systems

It is vital to remember that lime slaking is a particular process used to convert quicklime by mixing it with water into a hydrated one. Generally, lime slaking is an essential process that creates steam and generates heat, so we call it an exothermic process.

Hydrated or slaked lime is used in process industries and mining to neutralize acidic solutions and raising pH levels.

Generally, you can find them in dry powder form, which will allow you a chance to mix them into a particular solution. That way, you can slake it on-site without any additional hassle.

Remember that a cost per tone is higher than quicklime, which is affordable because it doesn’t have a usage rate.

Therefore, with a high percentage of using it, you can rest assured, because it will be more affordable and productive to create a slaking system than to buy already made directly from the supplier.

Of course, you should consider high upfront expense for a lime slaker, but it will be worthwhile as time goes by.

You can find a wide array of reliable and durable systems, which means that they can operate in harsh environments with ease.

Most components come with simple access for maintenance and cleaning, which means that you will need minimal operator involvement between production intervals.

Benefits and Features You Should Remember

Since it comes with a customized solution depending on your needs and preferences, you will find the one that will provide you with specific requirements.

At the same time, most of them are compliant with manufacturing specifications and customer engineering. A design process will use the latest technological guidelines and standards for process control, which will provide you peace of mind.

You can also implement various 3D models that will provide you with relevant strategies and plan for layouts. That way, you can determine whether the interface and tie-in are accurate.

Finally, you will get ergonomic options for the operator to handle the maintenance and drying process of quicklime with ease.

You should know that slaking systems feature a wide array of components, which means that every single part of the system will help you deal with the process.

The main idea is to create an appropriate design that will ensure production at specific rates you want to implement.

Components of Lime Slaking System

  • Dry storage and quicklime received; we are talking about a silo or large bag breaker that features level indication and dust collection.
  • Vibrating conveyors come in suitable sizes.
  • Heavy-duty rotary valves or screw feeders will feed dry quicklime.
  • Grinding ball mill is a roller mounter as well as a detention slaker.
  • Vortex feed bowl comes from stainless steel and features instruments and control valves.
  • Separation tanks and hydro-cyclone come on relevant grinding systems.
  • Sturdy slurry pumps that can transfer ring and transfer dosing pumps.
  • A tank features a level sensor and agitator.
  • Storage tank for agitated MOL
  • Control system with DCS plant integration
  • Access platforms

Process Control

The main goal is to use two essential aspects that feature quicklime and water. Therefore, you should add ingredients by following a particular formula or ratio with an idea to create a reasonable production rate.

You should also find ways to ensure conditions for slaking, which will provide you peace of mind. Feed rate depends on numerous factors, and you can control it by using a rotary valve or screw feeder, depending on the type you decide to get.

On the other hand, modulating the flow control valve and flow meter will determine and maintain the water flow rate.

You should know the ratio of quicklime and water before you start a process. Therefore, if you add too much water, you can affect or drown a reaction. As a result, you will prevent slaking because slurry won’t reach the proper temperature.

That will reduce the overall reaction, which will lead to unslaked issues within a storage tank.

Adding a low amount of water will lead to a build-up within feed pipes, which means that the mixture will become sturdy and thick. As a result, it won’t flow as it should, which may compromise an entire system.

The Ball Mill

When it comes to this component, you should know that it comes with two essential functions.

The first one will reduce hydrated lime and quicklime into tiny particles with an idea to create a proper reaction. Check out this guide: to learn more about different construction materials.

The second one will allow the chemical process to happen by rotating a vessel. Both methods will enhance eachother functions, which means that grinding will increase. That way, the chemical reaction will occur and break all particles inside into tiny sizes.

Ball mills are roller-mounted ones, while you can customize their size depending on preferences and needs. Everything depends on the throughput you require in combination with size. Most of them come from polyurethane rollers or rubber tires.
