Product Introduction

Double-stage vacuum structure, high vacuum degree. The vacuum degree can reach **-0.092 MPa**, ensuring thorough degassing of the clay material, resulting in dense brick blanks with high-strength finished bricks that are less prone to layer separation and cracking. Extrusion pressure is stable. The small-sized model features an extrusion pressure of 2.5–3.0 MPa, suitable for medium to small production volumes. The cutting blades are made of wear-resistant alloy, offering high durability and extended service life. The extruded mud strips are uniform with smooth surfaces, and the brick blanks exhibit consistent dimensions. Compatible with a wide range of raw materials. It can process clay, red soil, shale, coal gangue, and fly ash mixtures, demonstrating excellent adaptability to raw material moisture content. Even with fluctuations in raw materials at small-scale plants, it ensures stable production.
