Spring Compact
Spring Compact is a self-cleaning drum filtration system capable of treating from 100 to 5000 l/min of neat oil or emulsion. Drum filtration efficiency can be customised according to customer requirements.
Spring Compact has the special feature that it only processes the amount of coolant required by the machine; the clean liquid collection tank is welded as a single block with the filter. Spring Compact works in real time, eliminating sludge deposits in the tank and thus guaranteeing zero deposits at the bottom of the machine.
Given the characteristics of the filter, the system is designed and sized to the customer’s specific requirements.
This type of self-cleaning filter is especially suitable in the mechanical engineering and automotive industries, where there are machining operations involving chip removal with tools, abrasion removal, deformation and washing.
The Spring system uses a metal filter cloth which is cleaned by the Autoclean system. In this way, no consumable materials are used, significantly reducing maintenance and waste disposal costs.
This is an automatic cleaning system for the wire cloth used for filtering liquids. Inside the filter is a sensor that rotates the drum when the maximum filter cloth clogging level is reached. During the rotation, a countercurrent jet system washes the wire mesh, removing the residue while the dredging system scrapes the sludge from the bottom of the tank, transporting it to the outside.
It is used for the evacuation of filtered and decanted sludge; it can also be in a magnetic version for ferromagnetic residues.
The Spring and Spring Compact operating principle involves three phases:
- The filter cloth covering the drum is perfectly clean. The dirty liquid passes through it, depositing the polluting parts, and it finds the drain opening while passing inside it. Here, the liquid falls into the clean collection tank, from where it is then sent back to the machine tools. During this phase, the drum does not rotate and the dredging system is stationary. The pollutant material that settles on the cloth forms the actual filter layer, which can be up to 10-15mm thick.
- The filter cloth becomes dirty and the liquid level rises. The dirty liquid continues to deposit pollutants on the surface of the drum, which does not rotate and the dredging system is stationary. The degree of filtration improves due to the thickness of the sludge deposited on the cloth.
- When the cloth clogging cycle is complete and the liquid can no longer pass through, the best possible degree of filtration is achieved. The longer the filter runs in this condition, the better the average filtration will be. When the liquid in the clean tank reaches the minimum level, the Autoclean cycle starts automatically and the drum rotates. At the end of this phase, the cleaning cycle starts again from the beginning.
LOSMA guarantees that each purifier is individually tested through rigorous control procedures. A quality and functional test certificate is issued for each unit.
Magnetic rotating disc pre-filtration system for separating magnetic pollutant particles from coolant.
To facilitate the evacuation of ferro-magnetic swarf.
For supplying all utilities, controlling and managing all signals.
It is used to reduce the volume of sludge for disposal and to reduce the liquid it contains. However, the level of compaction that can be achieved depends on the type of sludge, the type of liquid and many other factors such as cycle times. Volume and moisture reduction is achieved by squeezing with static load. It has a volume reduction efficiency of 40% to 20% and liquid reduction efficiency of 30% to 10%.
