The Tekkem Slaker is fully automatic, requiring little or no regular operator attention. The proven RDP-Tekkem operating system takes input from load cells to precisely monitor the water weight and lime weight that are added to make a batch of lime. This information is combined with data from a thermocouple and then used by the program. Changes are made in the lime:water ratio to maintain optimum processing temperatures in the face of changes in the variables which affect the slaking reaction.
– Seasonal changes in process water temperature
– Changes in lime characteristics
– Changes in lime suppliers
65 plants have greatly reduced their maintenance time and cost.
Despite being simple, the mechanical design is rugged and assures years of low maintenance and reliable operation. The RDP-Tekkem Slaker has only one moving part inside the reaction tank which makes maintenance easy and infrequent. There are no bearings or seals located within the tank so the mechanical components are outside of the tank, away from dust and steam. Thus maintenance can be performed from the outside eliminating the need to access the inside of the tank. 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.
By using a precise weight control, the slaker is able to properly control the slaking reaction and dilution to an accuracy unmatched by other slakers. The proven RDP-Tekkem Operating System automatically reacts to changes in flow so that treatment conditions are maintained. The entire plant runs more efficiently with the operating system maintaining a steady pH state 24 hours a day.
Since 1960 when T.C Miller first published his award winning work, A Study of the Reaction of Calcium Oxide and Water, It has been known that the lime slaking reaction operates better when the reaction is run at elevated temperatures between 180°F to 190°F. The RDP-Tekkem Slaker consistently runs within a degree or two of a set point, then is precisely diluted to a usable slurry concentration. The accuracy is maintained in spite of process changes.
