03-09-2015· With a slaker, the lime silo should still be located close to the grinding area, since the SAG mill will be the major addition point, but it will not have to straddle the feed conveyor. The pebble lime / hydrated lime system is not best when compared to a 500 ton silo and detention slaker system.
Lime Slaker In the slaker lime and green liquor are mixed together to produce white liquor. The lime slaker is equipped with a sedimentation type classification device to remove unreacted lime and other reject material called grit from the system. Causticizers Three or …
the discharge of the feeder and inlet of lime feed to the slaker. Eventually, this build-up may break loose due to its weight and allow a few cubic feet of lime to enter the slaker suddenly releasing a large volume of steam and spraying hot lime slurry out of the slaker access doors. It is imperative that the operators check the steam removal system at least once or twice a shift for proper operation of the system.
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca() 2.It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed or slaked with water.It has many names including hydrated lime, caustic lime, builders' lime, slack lime, cal, and pickling lime. ...
To avoid this problem, lime specifications must limit the upper size of particles (e.g., < ½"). The size of the largest grit must be smaller than the clearance distance between the tip of the paddles and the body of the Paste slaker. Typically, in a Paste slaker, the water to lime ratio is about 2.5 to 1. As paste
A slurry slaker generally uses an initial lime to water ratio of 1 to 3.3 to 1 to 5 depending on the make of equipment and quality of CaO and water. Typically, a slurry slaker, sometimes called a detention type slaker, is comprised of two chambers. The first chamber is called the slaking chamber where lime and water are mixed.
Quicklime is reacted with water in a device called a "Slaker" in a process called "slaking". Slaking is an exothermic process meaning the heat is produced as the quicklime reacts with water and this heat must be managed by carefully controlling the ratios of water and lime and any resulting steam and dust must be captured for safety and housekeeping concerns.
The RDP-Tekkem Slaker sealed tank contains the dust so the work environment stays clean and safe for personnel. Lastly, the flexibility is extraordinary. Without any physical changes, the RDP-Tekkem Slaker can switch over and become an accurate hydrated lime feed system, allowing the use of either quicklime or hydrated lime depending on market prices and local preferences.

Series 7000 Paste Slaker – The Series 7000 paste slaker is user-friendly and provides consistent, highly accurate water-to-lime ratios thanks to our microprocessor control feature.
On July 15, 2018, KMBC News reported an explosion at a Kansas City water treatment facility. The incident occurred when two workers were dealing with a lime slaker. An excess amount of lime came into contact with water and created a lime slurry that caused chemical burns. Both employees were treated in hospital.
Lime Systems. Products and ... every conceivable aspect of the plant is designed with safety . being paramount and for ease of operation and maintenance throughout its service life. ... mounted ball mill slaker, cyclone classification and a 150 cubic metres agitated storage tank, plant ring main
Removing the slaker, however, significantly simplifies the process and reduces capital expenditure, maintenance needs, and safety risks. Easiest to use are ready-mixed lime slurries, such as CALSAFE. You no longer need to handle any dry bulk materials or deal with the challenges that this brings (such as …
lime from the airlock feeder to the lime slaker. The dosage control should be via airlock feeder. The conveyor will only transfer the lime from the airlock feeder to the slaker. In general, if the lime silo is fluidized, dry air must be used to avoid air slaking of the ... is no safety hazard.
The slaker is a combination vessel that consists of a large tank called, the slaker bowl and an incline classifer. Its purpose is to mix lime and green liquor and settle out the grits produced this reaction. The slaker bowl has an inlet for both lime and green liquor, an agitator, and a side discharge to the classifier.
Introduction to Lime types and ... Cleaning the slaker & grit remover: N/A LDLS Systems do not require grit removal. N/A HDLS Systems do not require grit removal: Removal/Disposal of grit. N/A LDLS Systems do not have grit; only a very minimal amount of impurities in the hydrate, maybe a few
DETENTION Slaker. Westpro's Detention Slakers have been engineered to handle pebble as well as fine lime. Our PLC based control system provides a safe and trouble free operation while functioning at peak productivity. ADVANTAGES. High reactivity product; Available in standard sizes up to 150tph
Lime is used in both municipal and industrial processes to improve water quality, by either controlling pH, removing impurities, or softening water. In systems that demand large quantities of lime, quicklime is ideal as the density is twice the density of hydrated lime, which reduces the …
Safety Precautions As Related To Operating A. This could then cause an accumulation of the dry lime in the chute between the discharge of the feeder and inlet of lime feed to the slaker.Eventually, this build-up may break loose due to its weight and allow a few cubic feet of lime to enter the slaker suddenly releasing a large volume of steam and spraying hot lime slurry out of the.
Lime Slaking Incorrect slaking temperature and water to lime ratios in the slaking operation can result in poor quality hydrated lime. If the slaker is not operated under negative pressure, steam and moisture travels back into the feeder and lime bin and causes "caking" problems.
03-09-2015· A lime slaking and addition system can consists of two systems to control the pH in the rougher and cleaner flotation circuits. A pebble lime silo will dose dry lime to the SAG mill feed belt; a hydrated lime make down system will provide slurry lime to multiple addition points in the flotation circuit.
