Screw Compactor
A screw compactor can be considered a multifunctional machine as it is capable of performing several operations simultaneously. In addition to screening waste, it also handles washing, compacting, and discharging. Because of its shaftless screw and lack of intermediate bearings, it is commonly used in municipal and industrial wastewater treatment plants, where minimizing maintenance is a top priority.
Advantages of Screw Compactor:
Dual Functionality: Both conveying and compacting.
Decreases waste volume by up to 40%.
Easy Maintenance
Clog-Free Operation even with fibrous materials.
Bounded Design: Prevents contamination, odor, and operates with low noise.
Low Energy Consumption
No External or Intermediate Bearings
Easy Discharge: The outlet design allows for discharge into plastic bags.
How the Screw Compactor Works?
The screw compactor is ideal for separating fine, medium, and coarse solids during the pretreatment of municipal and industrial wastewater. Constructed from stainless steel, it can be installed directly in the channel.
This compactor is considered a multifunctional machine because it performs several tasks: in addition to screening waste, it also washes, compacts, and discharges materials.
The most critical part of the device is the screening plate, which includes either a semi-circular stainless steel filet or a trapezoidal stainless steel filter, both with perforations, along with a stainless steel channel brushed by polyamide
Transporting and Compacting Waste
Compactors are used to compress, dewater, and reduce the volume of waste and various materials. They also function simultaneously as screw conveyors. Waste enters the machine through an input hopper, where it is transported, dewatered, compacted, and then discharged. The waste is fully sealed off, preventing the release of gases, vapors, and unpleasant odors. The specialized design of this device ensures precise tolerances, which reduces wear, power consumption, and operational costs.
Applications of Screw Compactor:
The screw compactor is a versatile machine, suitable for a range of processes in both continuous and intermittent modes. Its primary application is in municipal and industrial wastewater treatment units, where its shaftless screw design and absence of intermediate bearings ensure minimal maintenance requirements.
Operating Principles of Screw Compactor:
Screw compactors are typically installed in industrial wastewater treatment units, downstream of screens, for dewatering debris. Dewatering of high-water-content solids occurs at the top entry of the screw compactor, where they are conveyed by a shaftless screw towards the screen filter the compacting zone in which the water is separated from the solids. The compacting zone features a perforated basket that allows the water to drain. Finally, the dewatered materials are discharged through a pipe into a container, and the separated water is discharged from the bottom of the machine through a pipe for further treatment.
