Through three generations through multiple trials and experiences, We at Atlas Technologies has honed its expertise to meet the evolving needs of multiple industries. Our mission is to help businesses optimize their operations through efficient and reliable dewatering technology. We are committed to quality and customer satisfaction, providing tailored solutions that cater to the unique requirements of each client.
Our state-of-the-art screw presses are engineered for maximum efficiency, durability, and ease of maintenance. Whether you need to dewater sludge, pulp, or any slurry, our equipment ensures superior performance and cost savings.
The slurry or sludge is fed into the screw press through an inlet hopper.
Conveying and Compression: Inside the press, a rotating screw (also called an auger) moves the material through a cylindrical screen or filter. As the material progresses along the screw, the pitch of the screw flight decreases, and the diameter of the shaft increases, which compresses the material and forces the liquid out through the screen.
Filtrate Extraction: The liquid (filtrate) passes through the screen and is collected in a tray or container beneath the press.
Discharge: The dewatered solid material (cake) exits the press through a discharge outlet at the end of the screw.
A conical screw press is a specific type of dewatering screw press that incorporates a cone-shaped section at the discharge end to enhance dewatering efficiency. Here's a breakdown of its key features:
Core Functionality:
Similar to a standard screw press, it uses a rotating screw to continuously push material through a perforated screen.
The screw conveys the material and squeezes it against the screen, forcing liquids out and leaving behind a drier solid material.
The Conical Advantage:
The key difference lies in the screw shaft itself. In a conical screw press, the shaft has a gradually decreasing diameter as it progresses towards the discharge end. This creates a conical shape.
As the material travels through the press and encounters the conical section, it experiences increasing pressure. The decreasing diameter forces the material outward against the screen, maximizing liquid extraction.
Benefits of Conical Screw Presses:
Higher Dryness: Compared to standard screw presses, conical designs can achieve a drier final product (cake) due to the enhanced squeezing action of the cone.
Improved Efficiency: The conical design allows for more efficient dewatering, potentially reducing processing time and energy consumption.
Versatility: Conical screw presses can handle a wider range of materials due to the ability to adjust the pressure exerted by the cone.
Applications:
Conical screw presses are particularly suitable for materials that are:
Difficult to dewater with standard screw presses
Shear-sensitive (where minimizing mechanical damage is important)
A cylindrical screw press is the more standard type of screw press compared to its conical counterpart. Here's a breakdown of its key features and how it differs from a conical screw press:
Cylindrical Design:
The screw shaft maintains a consistent diameter throughout its entire length, forming a cylindrical shape within the press.
Material is continuously fed into one end and progresses along the screw conveyor until it reaches the discharge end.
Dewatering Process:
The rotating screw steadily moves the material against a perforated screen along the cylindrical housing.
As the material travels through the press, the screw's pressure and the screen work together to separate liquids from solids. Liquids pass through the perforations, while the solids are compacted and pushed towards the discharge end.
Applications:
Cylindrical screw presses are widely used in various industries due to their:
Simplicity : They have a relatively straightforward design, making them easy to operate and maintain.
Versatility : They can handle a wide range of materials with moderate dewatering requirements.
Cost-Effectiveness : Their simpler design often translates to a lower initial investment compared to conical presses.
Key Differences from Conical Screw Presses:
Pressure Profile: Cylindrical presses maintain a more consistent pressure throughout the press length, while conical presses have an increasing pressure towards the discharge due to the narrowing cone.
Cake Dryness: Cylindrical presses typically achieve a less dry final product compared to conical presses due to the constant pressure.
Material Suitability: Cylindrical presses are better suited for materials that are easier to dewater and where a very dry cake isn't crucial.
In summary, a cylindrical screw press is a versatile and cost-effective option for various dewatering applications, while a conical screw press offers superior dryness but may be more suited for specific materials or when a very dry final product is required.
A Multi Disk screw press is a specific type of dewatering screw press designed for high performance and efficiency, particularly well-suited for materials that tend to clog traditional screw presses. Here's a breakdown of its key features and how it differs from standard screw presses:
Core Functionality:
Similar to a standard screw press, a Multi Disk screw press utilizes a rotating screw to continuously push material through a perforated filter element. This filter element separates liquids from solids, allowing liquids to pass through and solids to be compacted and discharged.
The Multi Disk Advantage:
The defining characteristic of a Multi Disk screw press lies in its unique Multi Disk design. This refers to the progressively decreasing space between the screw shaft and the filter element as the material moves towards the discharge end. Here's how it works:
The filter element is typically composed of fixed and moving rings stacked around the screw shaft.
As the screw rotates, it pushes the material through the filter element.
The Multi Disk design, with its decreasing space, creates increasing pressure on the material. This progressive squeezing action efficiently extracts liquids.
Self-Cleaning Mechanism : A key advantage of Multi Disk presses is their inherent self-cleaning feature. The moving rings within the filter element are designed to continuously scrape against the fixed rings. This scraping action helps prevent clogging of the filter mesh, reducing maintenance requirements compared to standard presses.
Benefits of Multi Disk Screw Presses:
High Efficiency : The Multi Disk design allows for efficient dewatering with good dryness in the final cake, potentially reducing processing time and energy consumption.
Clog-Resistant : The self-cleaning mechanism minimizes clogging of the filter mesh, making them suitable for materials that can clog traditional presses.
Reduced Footprint : Multi Disk presses can achieve similar dewatering performance as standard screw presses in a smaller footprint, making them ideal for applications with limited space.
