It is flexible. It is efficient. It is ideal for raw material grinding. It is the static LS separator: the almost maintenance-free choice for achieving a variety of cut sizes, depending on your process specifications.
Now you are wondering how the LS achieves all of that. Read on and allow us to explain some of the features!
Easily-adjustable guide blades
All guide blades are connected to an electronically-adjustable ring that is controlled from the central control room. So, you can move all of the blades, simultaneously, with a single command. It enables quick and easy adjustment of the cut point and provides a lot of flexibility to maintain fineness at the required level, without a lot of effort.
A unique feature of the LS separator – so take note! Feed material is first thrown against an impact cone, knocking very coarse material out of the airflow before reaching the separation chamber. This reduces recirculation rates and makes the LS separator one very efficient machine.
Low air velocities, low pressure drop
There is no denying it: the LS is a big machine. On the upside, air velocities through the separator are very low. Combined with its shape and construction, it means pressure drop in the LS is one of the lowest in our range.
You have read about some of the features of the SKS-V/Z. But how exactly do they benefit you?
Low power consumption
An all-important benefit in a market where all costs and environmental impacts are so heavily scrutinized. As a static separator, the LS consumes very little energy to achieve results. Meanwhile, pre-separation of the very coarse particles means less energy is wasted circulating oversize material through the separation chamber.
And for the hat-trick: the low air velocity and pressure drop reduce the necessary fan power and lower energy consumption across the grinding circuit. That is three reasons why the LS is good for your electricity bills and better for the environment.
Almost no maintenance
We are not going to lie. The size of the LS makes maintenance more difficult than on some of our smaller SKS machines. But do not let this put you off: maintenance is very rarely required! There are basically no moving parts – just a motor to move the air blades, which is located on the outside for easy access.
The only maintenance needed therefore is to check and replace wear parts. But the low velocity of material passing through the separator results in much less wear on the internal components than in our dynamic separators. It basically runs and runs, with very little to worry about in terms of potential downtime.

How it works
Material feeds from below, against an impact cone, and up to the separation chamber. Fines continue up and out; coarse material falls down and is discharged.
