Front Stencil Mixing Extruder Pre-screen Extruder Block Making Machine

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.

Raw Material Pre-processing: Performs preliminary extrusion and homogenization of mixed raw materials to improve uniformity.
Impurity Filtration: Filters out large impurities and unbroken hard lumps through the mesh plate.
Enhanced Vacuum Extrusion Efficiency: Pre-compresses the material, reducing the workload on the vacuum extruder.
Improved Product Quality: Ensures more uniform material, minimizing defects in finished bricks.
Downstream Equipment Protection: Prevents large hard objects from entering the vacuum extruder and causing damage.

Structural Features
Mesh Plate System: The core component, made of high-strength wear-resistant steel, with adjustable apertures based on product requirements.
Extrusion Screw: Utilizes a variable-diameter and variable-pitch design to gradually increase extrusion pressure.
Drive System: Equipped with a high-power motor and gear reducer to provide stable torque output.
Casing Design: Heavy-duty and robust construction, lined with wear-resistant materials to extend service life.

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

● Project reference from Xi’an Brictec

1.Shaoxing Lvzhan environmental protection technology Co., Ltd

Xi’an Brictec designed this Lvzhan project in 2023. The project has annual output of 300,000㎡ of sintered bricks and prefabricated brick wall by using local solid waste such as chemical contaminated soil, construction residue, printing and dyeing sludge as the main raw materials, etc. so as to make high quality sintered bricks making, and 60%-70% of electricity needed for production line is from the photovoltaic power generation on the factory roof. Xi’an Brictec provides whole package service from the preliminary planning and design of the project to the supply of core equipment in the later stage. Single layer tunnel dryer process is adopted with natural gas burning system for tunnel kiln (7 meters inner width). Xi’an Brictec has delivered a very satisfactory EPC project to our client, and also set a new benchmark for the solid waste recycle and utilization in the industry.

2.Najmadin project in Iraq

This project was jointly designed and implemented by Xi’an Brictec and China National Building Materials Co., Ltd. in 2023, with a daily output of 750 tons of sintered bricks. It is located in Sulaimani Province, Kurdish region of Iraq, and the raw material is shale. Xi’an Brictec has participated in project planning, design, construction and commissioning. Single layer tunnel dryer process is adopted, and Heavy oil/liquefied petroleum gas dual fuel serve as the fuel for dryer and tunnel kiln (9 meters cross-section) . In this project, Xi’an Brictec competes with European production line on the same platform and wins honor for the country. So far the project has been put into production, expecting to meet the production target in May 2024.

3.Antique Bricks Project for Yan'an Green Building Material Recycling Industrial Zone

The project was designed and implemented by Xi’an Brictec as a whole in 2022, mainly to produce antique bricks, facing bricks and paver, etc.. The raw material is high-quality shale and purple sand soil, and the fuel is natural gas. The entire production line combines two shaping methods (extruding and pressing), and uses chamber dryer for drying and tunnel kiln for burning, and integrates three shuttle kilns for antique bricks production. Xi’an Brictec was fully engaged and offer excellent package service in the project in the preliminary process design, dryer construction and core equipment supply and production commissioning. This automatic degree applied in this project is the highest domestically, also meets the advanced international level.

4.Guangdong Baolihua Electric Power Co. Ltd. brick making project with high content fly ash as raw material

Xi’an Brictec designed the whole project and led multiple raw material batching experiments, and finally got the result of 65% fly ash content being the perfect ratio to produce qualified sintered bricks. And because of this project, Xi’an Brictec has obtained the invention patent for making bricks with high content fly ash added.

5.ECO CERMICS project in Bangladesh
This is an EPC project by Xi’an Brictec. Single-layer tunnel drying process is adopted with two 4.8-meter tunnel kilns in use. Bongianni soft plastic extruder from Italy， roller and pulverized coal burner invented by Xi’an Brictec are also applied in this project. Invested by GPH, the 3rd largest cement enterprise in Bangladesh, the production line has the characteristics of highest automation and largest production scale. The factory roof is laid with solar photovoltaic, offering 60% power generation for production line.
