Industrial shredders are heavy-duty machinery specifically designed to crush, cut, or tear large, dense, or irregularly shaped waste materials (such as paper, plastics, metals, rubber, wood, textiles, and electronic waste), significantly reducing their volume and uniform shape for easier recycling, reuse, or safe disposal.

Main Functions and Effects

Volume Reduction: Crushes large materials into particles of 40-150mm or even smaller, significantly reducing transportation and storage costs.

Material Pretreatment: Provides suitable particle sizes for subsequent sorting, melting, and briquetting processes.

Safe Disposal: Thoroughly shreds confidential documents, hard drives, and sensitive electronic products to prevent information leakage.

Environmental Benefits: Transforms waste that would otherwise go to landfills into reusable raw materials, reducing landfill volume and meeting the requirements of green manufacturing and a circular economy.

Steel Plastic Geogrid is a composite geogrid composed of high-strength steel wire and plastics such as polyethylene (PE). Its typical manufacturing process is as follows:

Material Composition: Inner Core: Specially treated high-strength steel wire (or other fibers) provides the main load-bearing skeleton of the geogrid.

Outer Layer: High-density polyethylene (HDPE) or other plastics are coated or wrapped around the steel wire surface, with anti-aging and anti-oxidation additives added to form a protective layer that is corrosion-resistant and wear-resistant.

Forming Method: The steel wire and plastic layer are extruded together into strips, and a rough embossed pattern is pressed onto the surface to increase the friction coefficient with the soil.

Welding is performed at the intersections of the longitudinal and transverse axes using ultrasonic or injection welding techniques to form a biaxial or uniaxial geogrid.

Main Properties: High tensile strength (up to 15–150 kN/m), high stiffness, and low deformation.

Excellent corrosion resistance: The plastic protective layer allows it to be used for more than 100 years in harsh environments such as acids, alkalis, and salts. The rough surface increases the friction coefficient between the geogrid and the soil, enhancing its resistance to slippage and lateral compression.

It is wear-resistant and aging-resistant, suitable for long-term permanent engineering projects.

Typical Applications Road and Railway Subgrades: Improves subgrade bearing capacity, extends service life, and prevents pavement settlement and cracking.

Dikes, Retaining Walls, and Slope Reinforcement: Prevents soil slippage and erosion; suitable for soft soils and coastal embankments.

Large Permanent Infrastructure such as Bridges, Airports, and Docks: Provides high-strength, long-term stable support.

Others: Such as mine support and landscape slope vegetation subbase.

Geogrid Equipment refers to specialized machinery and equipment used to manufacture and process geogrid (ground grid) materials. This equipment typically includes ultrasonic plastic welders, PLC control systems, touchscreen parameter setting panels, extruders, and heat-stretching machines. These machines are used to process polymer materials like polyester, polyethylene, and polypropylene into high-strength geosynthetics with a grid structure to meet the soil reinforcement needs of projects like roads, railways, embankments, and slopes.

Geocell is a three-dimensional lattice cavity structure formed from high-strength HDPE sheets through ultrasonic needle welding or high-strength welding, often referred to as a "honeycomb cell restraint system." This structure can be expanded and contracted on-site, allowing for flexible transport and stacking. During construction, it can be stretched into a grid and then filled with loose materials such as soil, gravel, and concrete to create a monolithic structure with strong lateral restraint and high rigidity. Using polyethylene that is resistant to aging, acid, alkali, light, and oxidation, Geocell is lightweight, wear-resistant, and chemically stable, making it suitable for use in harsh environments such as a variety of soils and deserts. Jiangsu Saide Machinery Co., Ltd., a professional Geocell manufacturer, utilizes state-of-the-art uniaxial and biaxial stretching equipment and post-processing devices to ensure Geocell products possess high tensile strength and low elongation, meeting the needs of domestic and international projects.

A granulator is a machine that mechanically processes bulk or wet raw materials into uniform granules or pellets through cutting, compression, extrusion, or spraying. It is widely used in industries such as feed, fertilizer, fuel, biomass, plastics, pharmaceuticals, and food, facilitating subsequent drying, tableting, packaging, or conveying.

Working Principle The core of a granulator is a high-speed rotating screw or die roller. The screw's compression and friction increase the temperature and pressure of the raw materials. As the material enters the annular die, it is forced into shape and cut by cutting tools to form pellets. In a wet granulator, the raw materials are first moistened with water or steam. The water is then rapidly evaporated under high temperature and high pressure, causing the water to expand and form porous, low-moisture granules.

Main Types Screw granulators: Suitable for powdered or granular raw materials, commonly used in feed and fertilizer production. Disc granulators: Utilize centrifugal force and gravity to cause fine particles to roll and bond on a disc surface. They are suitable for granulating chemical raw materials such as sulfur. Double-cone, fluidized bed, and other processes: Specialized processes for varying viscosity or particle size requirements.

Applications Feed pellets: Process raw materials such as grain and soybean meal into pellets that are easy to store and feed. Fuel pellets: Convert biomass such as straw and sawdust into fuel pellets that can replace coal for applications such as home heating and power generation. Fertilizer pellets: Wet or dry granulation improves fertilizer flowability and application uniformity. Plastics and pharmaceuticals: Granulate raw materials into uniform pellets before injection molding or tableting, improving processing efficiency and product quality.

Advantages Uniform particle size facilitates subsequent process control. Adjustable moisture content meets different drying or combustion requirements. Relatively low energy consumption, especially with disc pelletizers, which utilize centrifugal force to achieve natural bonding. High adaptability: A variety of pellet sizes can be produced by replacing molds or adjusting the speed.

Geogrid is a grid or lattice structure made of high-molecular-weight polymers (such as polypropylene (PP), polyethylene (HDPE), and polyester (PET)) with regular open pores. It forms mechanical bonds within the soil, significantly improving its bearing capacity, settlement resistance, and shear stability.

Materials and Manufacturing Processes

Bidirectional geogrid production line is a kind of equipment specially used for producing bidirectional geogrid. Bidirectional geogrid is a geosynthetic material made of high molecular polymer material, which has the characteristics of high strength, high toughness, high corrosion resistance and high weather resistance. It is widely used in civil engineering, road construction, water conservancy construction, environmental engineering and other fields. Bidirectional geogrid consists of longitudinal stretching part and transverse stretching part. The bidirectional stretching process makes the material have high strength and stiffness in both directions. This structure enables the bidirectional geogrid to evenly disperse stress when bearing load, and improve the bearing capacity and stability of the soil. Raw material preparation system: pre-treat the polymer material to reach the temperature and state required for production. Extrusion system: extrude the pre-treated raw materials into sheets or strips through an extruder to form the base material of the geogrid. Stretching system: bidirectionally stretch the extruded base material through a stretching device, so that it has high strength and stiffness in both longitudinal and transverse directions. Cooling and shaping system: cool and shape the stretched geogrid to keep a stable shape and size.

Rolling and packaging system: The geogrid is rolled and packaged after cooling and shaping for easy transportation and storage.

Production Line of Uniaxial Tensile Geogrid is a high-strength geotechnical material with a complex and sophisticated production process, which is achieved through a series of advanced equipment and process flows. The production line uses high molecular polymer as raw material and completes the production of products through multiple steps such as heating, extrusion, molding, and stretching.

Raw material heating and extrusion: The high molecular polymer raw material is heated to a molten state and then extruded through an extruder to form a continuous sheet. This process ensures the uniformity and continuity of the material and lays the foundation for subsequent processing.

Plate mold molding and cooling: The extruded sheet enters the plate mold and is cooled and shaped through a cooling water tank to achieve the required size and shape. The cooled sheet is conveyed to the punch press for the next step of processing.

Stamping molding: In the punch press, the sheet is cut into regular shapes to form a preliminary grid structure. This link ensures the dimensional accuracy and consistency of the product.

Heating and stretching: The stamped sheet is directly sent to the oven for heating through the conveyor belt, and then enters the stretching device. The sheet is longitudinally stretched by the stretching equipment to form a high-strength unidirectional tensile structure. The stretching process can significantly improve the tensile strength and modulus of the material, making it reach or even exceed the level of low-carbon steel.

Finished product measurement and packaging: After the stretching is completed, the product is measured to confirm the size and performance, and then it is wound and packaged to complete the production process.

Raw material preparation: Production Line of Uniaxial Tensile Geogrid usually use high molecular polymers as the main raw materials, and add modifiers such as UV protection additives and anti-aging additives to improve the durability and performance of the material.

Extrusion molding: The mixed plastic raw materials are heated to a molten state through an extruder, and then extruded into a thin plate through a plate mold. During the extrusion process, the appropriate temperature and pressure must be maintained to ensure that the plastic evenly fills the mold cavity to form a plate with a stable size and shape.

Cooling and shaping: The extruded plate enters the cooling water tank for rapid cooling to shape it and maintain a stable geometric shape.

Punching treatment: The cooled plate is transported to the punching machine for punching to form a regular hole mesh structure. The surface of the punched plate is smooth and flat, ready for the subsequent stretching process.

Heating and stretching: The punched plate is sent to the oven and heated to a certain temperature (usually around 70°C) to make it sufficiently plastic. The plate is stretched in the stretching device along the length direction, so that the originally scattered chain molecules are rearranged into a linear state, thereby significantly improving its longitudinal tensile strength.

Secondary stretching (optional): Some production lines will use secondary stretching technology to improve the mechanical properties of geogrids. Secondary stretching is usually based on the first stretching, and the plate is stretched horizontally or longitudinally again to enhance its overall strength and stability.
