Condition: new, Year of construction: 2025, Roll forming metal siding “double façade panel” machine SPM-2 Roll forming metal siding “double façade panel” machine SPM-2 is new design product of our company for façade and wall metal panels forming with the necessary configuration. These double façade panels are very popular in construction business of cladding residential buildings and industrial structures, for the construction of fences of various configurations, gazebos, roofing elements, etc. The SPM-2 metal siding production line is fully automatic and consists of a rolling part of the machine, an automation system and guillotine cutting shears at the machine exit. The line can have as additional parts a manual or automatic uncoiler for metal rolls, depending on the customer's needs. As standard version, this metal siding double façade panels roll forming machine SPM-2 makes a flat panel profile, but with the additional equipment, it is possible to roll panels with a microwave or rib shape profile. To start rolling, it is necessary to install a roll of metal to the decoiler and to put the end of the strip to the first rolling rollers of the equipment and feed it into them. After step by step, to put the metal to the next rollers, adjusting it if necessary. Ijdjxghngepfx Addetb When metal comes to the cutting device of machine you need to feed metal into cutting knives and to make “zero” cut. After such step, equipment can move to automatic operation mode. The control panel of machine has the ability to set the number of tasks and the length of products, single tasks or to work in multitasking mode. After setting up necessary parameters the machine will automatically roll the metal cladding wall panels and cut them into necessary sizes. Thus, the customer will receive final product as quickly as possible and with the highest possible result. The roll forming speed is adjustable and can be up to 10-15 meters per minute. The SPM-2 metal wall cladding panels production line has special tools for punching out fastening holes on the side of the panel. It makes possible for the customer to get more interesting solution options and to offer a wider range of products to the end user. The rolling part of the machine has 18 pairs of forming steps, ensuring high quality of final product. You can get machine with protective cover or without it as per your request preferences.

Condition: new, functionality: fully functional, power: 11 kW (14.96 HP), Year of construction: 2025, A spiral-type sand washer machine, also known as a spiral sand washing machine or screw sand washer, is a piece of equipment designed for washing, classifying, and dewatering sand and other granular materials. This type of sand washer typically features a spiral or screw-shaped structure for the purpose of lifting, conveying, and washing materials. Here are key features and aspects of a spiral-type sand washer machine: 1. Spiral Structure: The core component of the machine is a spiral or screw-shaped structure, often enclosed within a tub or trough. This spiral impeller is responsible for lifting, conveying, and washing the sand as it rotates. 2. Tub or Trough Design: The spiral structure is usually housed within a tub or trough that holds the water and sand mixture. This design allows for efficient washing and separation of impurities from the sand. 3. Multiple Blades: The spiral impeller typically has multiple blades or flights that provide mechanical agitation to the sand, ensuring thorough cleaning. 4. Water Injection: Water is injected into the tub or trough to aid in the washing process. The combination of water and the rotating spiral helps to remove impurities from the sand. 5. Adjustable Weirs: Some spiral-type sand washers have adjustable weirs or gates that control the flow of water and the retention time of the sand in the machine, allowing for customization of the washing process. 6. Classification and Dewatering: Spiral sand washers often include features for classifying and dewatering the sand. This may involve the use of a separate compartment or mechanism for fine sand recovery and water drainage. 7. Variable Speed: The rotational speed of the spiral can often be adjusted to optimize the washing process for different types of materials and particle sizes. 8. Capacity: The capacity of a spiral-type sand washer is influenced by factors such as the size of the machine, the pitch of the spiral, and the efficiency of the washing process. Different models are available to suit various production requirements. 9. Materials Handling: Spiral sand washers are commonly used in applications such as aggregate processing, mining, concrete production, and other industries where the removal of impurities from sand is essential. 10. Ease of Maintenance: Many spiral-type sand washers are designed for easy maintenance, with accessible components and inspection points. Itjdpfxeq Nf S Ro Addjb Spiral-type sand washer machines are efficient tools for cleaning and processing sand, ensuring that the final product meets quality standards for use in construction, concrete production, and other applications. The specific features and capabilities of these machines can vary between different models and manufacturers.
