Product Description

Equipment Introduction:
Pre-screen Extruder is a key piece of equipment in the brick and tile production line, primarily used for raw material pre-processing and primary forming. Positioned before the vacuum extruder, it is referred to as a "pre-screen" device. This equipment screens and preliminarily compresses the raw material through a mesh plate, preparing it for subsequent vacuum extrusion molding.

Functions:
1. Raw Material Pre-processing: Performs preliminary extrusion and homogenization of mixed raw materials to improve uniformity.
2. Impurity Filtration: Filters out large impurities and unbroken hard lumps through the mesh plate.
3. Enhanced Vacuum Extrusion Efficiency: Pre-compresses the material, reducing the workload on the vacuum extruder.
4. Improved Product Quality: Ensures more uniform material, minimizing defects in finished bricks.
5. Downstream Equipment Protection: Prevents large hard objects from entering the vacuum extruder and causing damage.
Structural Features:
1. Mesh Plate System: The core component, made of high-strength wear-resistant steel, with adjustable apertures based on product requirements.
2. Extrusion Screw: Utilizes a variable-diameter and variable-pitch design to gradually increase extrusion pressure.
3. Drive System: Equipped with a high-power motor and gear reducer to provide stable torque output.
4. Casing Design: Heavy-duty and robust construction, lined with wear-resistant materials to extend service life.

Technical Features:
1. High Processing Capacity: Capable of 30-100 tons/hour (depending on model specifications)
2. Adjustable Pressure: Extrusion pressure controlled by regulating mesh aperture and screw rotation speed
3. Wear-Resistant Design: Critical components made with special alloys or wear-resistant coatings
4. Automated Control: Can integrate with full-line automation systems for intelligent adjustment
