Stage Lime Hydration production line----for making Dry hydrated lime powder

The crushed and weighed quicklime from the constant weight feeder enters the three-stage lime hydrator where water is mixed with the quicklime in the required proportions to achieve complete hydration. According to different process requirements, it is able to make serous fluid become different sized hydrated lime powder by the air separator.

Three-stage Lime Hydrator---- for make Dry hydrated lime

Principles and advantages of three-stage dry power hydrator

1. Three stage reaction with water distribution

The hierarchical & scientific distribution of water can make the calcium oxide to be fully pre-hydrated. After contacting with reasonable water in the first stage reaction chamber, the mixture enters into the second stage. This process is the best time for hydrating. When entering into the third one, hydrated lime is already semi-dry state. Three stage hydrator can finally make the calcium completely become the fluffy powder. And the entire reaction process just needs 8-15 minutes.

2.Time control

It will control the time of reacting water and calcium oxide, fully hydrating just needs 8-15 minutes.

3 Insulation function

Hydrator has good insulation function. As we all know, temperature may influence the rate of chemical reaction. The unique design makes it possible to reuse the vast heat which generated from the reaction inside the hydrator. It will raise the inner temperature to 60 degrees by only 3-5 minutes and make the calcium oxide to be fully hydrated.

4 Feeding process control

To pour the needed materials into the first-stage reaction chamber, screw feeder plays a extremely vital use for preventing hot steam and dust flowing back into the screw feeder, otherwise that will affect the accuracy of sensor.

5. Remove dust to keep clean and healthy

This device, according to environmental requirements, equipped with our patent dust remove device, will solve the problem of the steam and dust pollution produced during hydrating ,so that ensure the clean of the environment and the health of workers.

Our advantages

1.Year of experience with lime and hydrating systems.

2.Research and Developed patent Dust Collector which especial for Lime dust

3.True understanding of process conditions. Choose best equipment for each customer.

4.Capable of installation anywhere around the world.

5.Control systems for entire facility.

Two stage hydrator for Industry application:

Construction filed, water treatment ... ...

1. Application area and main functions

Widely applied in lime producing line for lime plants , lime hydration which in the sintering process of ironworks, building material manufacturing line for mining area, desulfurization equipment, calcium treating machine in sewage treatment, high quality hydrated lime producing line. Though a series of reaction in two stage lime hydrator, quicklime transfer into hydrated lime and moisture less than 8%.

2. Features of two stage lime hydrator

Compared with three stage lime hydrator, the two stage one can save cost and space which is more suitable to the enterprise in short of the height of workshop.

3. Standard technology index

Capacity :1-30 t/hr

Percent conversion: 85%

BET:Standard

Retained moisture: less than 6%

Dustiness at the vent of dust collector: less than 10 mg/m³

Standard consumption (hydrated lime 95%,fluctuate against actual specification)

• Quicklime needed: 0.75t/every tone hydrated lime
• Water needed: 0.5m³/ every tone hydrated lime
• Power needed: 3 kWh/every tone hydrated lime

Important matched part----dust collector

(wet scrubber)

Patent technology for Dust Collector

1.widely use:

To deal with the dust and harmful gases produced in the process of lime hydration of steel & Iron plants, power plants, chemical plants etc.

2.principles and features:

It can meet the needs of a variety of processes. This equipment is adopted the atomization dust removal and the impact water filtration technologies, enable to deal with the dust and harmful gases produced in the process of lime hydration. That means the abandoned dust of quicklime can be recycled and there is no dust pollution at the scene environment. It will help burnt lime hydrator reasonably allocate water needed during the lime hydration. Different specification of lime hudrator will be choosed according the quicklime feeding amount of different enterprise to hydrate quicklime acdequately.

3. advantages:

After the dust removal device and the lime hydrator forming a complete set, the lime hydration ratio can exceed 90%, the dust extraction ratio can reach 99%.

Centrifugal Separator

Key function

separate out small powder size and get high passing rate after classification.the design adopts suspension disperse technology,

pre-separating technology and plate bow wave technology which is special for high quality powder materials.

over 90% can pass 235mesh.

Automatic packing machine

Apply to excellent mobility of powder, granular material of packing processing.

Performance and feature:

1. weighing accurate, stable performance, simple operation;

2. good sealing, reasonable structure, wear well;

3. small size, light weight, convenient adjustment and maintenance;

4. mechanical and electrical integration, save power; This machine use air compressor and solenoid valve with help of mechanical and electrical integration and principle of lever linkage to reach such automatic function of compaction, disengaging, closing of gate and dropping bag.

Automatic PLC control system

PLC control system can realize the fully automatic control. This machine is operated by remote virtual control room which is easy to handle and reduce labors quite a lot. 3-4 persons can reach the well-operate of the whole line.

Control ranges: 1. feeding material 2. water adding condition 3. proportion of water-quicklime

4. linkage control of whole system 5.failure warning 6.temperature test and others.
