Help: Problem with transporting lime milk
Thread Content
Dear teachers, I have a question. The details are as follows: 1. After being processed by the slaking machine, the lime milk (with a concentration of 12-14%) flows into a pool that is 2 meters deep. What kind of pump is generally used to pump this lime milk out? 2. Will the lime slurry digested by the slaking machine precipitate quickly after being left to stand for one or two hours? Does the lime slurry after standing need to be stirred before it can be pumped? Thank you!
A centrifugal pump will do; a slurry pump is also fine
Transportation can be done using carbon steel pipes; stirring should be provided in the tank, and a 2PN slurry pump can be used for pumping.
It can be transported using many pumps. For centrifugal pumps, pneumatic diaphragm pumps, peristaltic pumps, and cam rotor pumps, it depends on the flow rate and pressure required. It is best to stir first and then pump it.
A reciprocating slurry pump for mixing cement is the best option; it doesn’t need to stop, and the time required can be reduced appropriately – no mixer is needed!
I’m very familiar with issues related to lime slurry. A pump for pumping lime slurry can be a slurry pump; carbon steel ones will work just fine. We’ve been using them for many years. Make sure that the lime slurry storage tank is equipped with a mixing device – the rotation speed doesn’t need to be very high; 30 rpm is sufficient. A filter must be installed before the inlet of the lime slurry pump; it can be a simple filter. I doubt there’s any need for me to explain in detail how to construct such a filter. (We used to be a petrochemical plant that produced epoxides using the chlorohydrin process, and we used large amounts of lime slurry.)
To reiterate, the mud pump is a centrifugal mud pump.
To transport such lime milk over a distance of 1500 meters, with a pump that has a flow rate of 100 and a head of 40 meters, what size pipe is required? PE pipes are not necessary

I am also considering the selection of a slurry transport pump; this post is very helpful, thank you
