Heavy-duty auger bottom scrapers are a type of equipment used for cleaning and transporting solid or semi-fluid materials (for example, sludge, waste, grain or coal) that have accumulated in large storage tanks or pits. These installations are widely used in industrial enterprises, treatment plants, mining areas and other large facilities.

The basic components of heavy type screw bottom scrapers are:

1. **Spiral**: It is a spiral-shaped blade that rotates around a central shaft, usually with a long and strong structure. The screw collects the materials accumulated at the bottom of the warehouse and carries them upwards.

2. **Drive mechanism**: It is the motor and drive system that rotates the helix. This system allows the screw to rotate at the desired speed and torque.

3. **Bottom scraper arm**: It is an arm mounted under the auger and used to scrape material accumulation. This arm contacts the tank floor and pushes the accumulated material into the screw.

4. **Support structures**: Structures that support and keep the screw bottom scraper stable. These structures are usually made of strong and durable materials and are designed to support the heavy loads of the auger.

Heavy-duty screw bottom scrapers are a very effective and efficient solution for cleaning materials accumulated at the bottom of storage tanks or pits. These equipment are designed for continuous operation, eliminating material accumulation, increasing the operating efficiency of businesses and reducing maintenance requirements.
