Separation Material: Ammonium Chloride Solution → Product: Ammonium Chloride
Operating Principle
Suspension flows into the spiral cavity via the feed pipe and enters the rotating drum through the nozzle at the screw’s cone end. Under centrifugal force, slurry liquid passes through the drum wall screen while solid particles are retained. Driven by centrifugal force and the speed difference between screw and drum, solids travel from the drum’s small end to its large end. Growing centrifugal force reduces solid moisture from inlet to discharge, achieving automatic continuous solid-liquid separation.
Special Equipment Improvement
Salt Extraction From Waste Liquid
Improvements made by Bhoumik in special equipment for extracting salt from waste liquids such as ammonium sulfate, ammonium chloride, ammonium thiocyanate, and sodium chloride.
Feed Pipe Device
The feeding pipe device is improved, the distribution is more uniform, and the equipment operation is more stable.
Lubrication System
The lubrication system is improved, the lubrication is more adequate and reasonable, and the service life of the bearing is increased.
Bearing Sealing System
Improved bearing sealing system, using labyrinth oil seal to prevent mother liquid from entering the lubrication system.
Wear Resistant Treatment
The drum spiral is treated with nitriding and wear-resistant, which has a longer life.
Discharge System
The discharge system is improved, and a scraper device is added to prevent the storage bin from accumulating.

Main Features
Main parts such as drum and screw can be made of corrosion-resistant stainless steel or titanium alloy.
Special filter, the thickness of the filter reaches 0.5mm, and the service life is longer.
Stepless speed regulation of drum speed.
Spiral differential speed is adjustable: stepless or stepless speed regulation.
Simple and reliable circulation lubrication method, including pressure regulation, oil filtration and water cooling system.
Safety protection: speed detection, over-vibration protection, motor overload and overheat protection, spiral zero differential protection.
For high viscosity materials, a hydraulic differential can be selected, which is stable and reliable.

Successful Application Cases of LWL
Horizontal screen scroll centrifuges have been widely used in chemical, food, salt, mining, pharmaceutical and other industries. However, due to its separation principle and structural characteristics, it is more targeted to materials. Material analysis and corresponding experiments should be carried out during the selection to determine its applicability and separation performance.
It is mainly suitable for material particles with larger particle size and no strict requirements for particle damage, such as fibers, plastic particles, and various crystals.
