Scraper Arch Breaker

In the industrial production field, the storage and discharging processes of powder and granular materials often face problems such as bridging, hollowing, and segregation, which seriously affect production continuity and material utilization rate. Scraper arch breakers, as key discharging equipment, are widely used to solve these issues in various industries.As the core auxiliary discharging equipment at the bottom of silos, scraper arch breakers effectively address the above pain points with their scientific structural design and excellent performance, and are widely applied in industries such as chemical engineering, food processing, pharmaceutical manufacturing, and building materials.

Core Components of Scraper Arch Breaker:

The stable operation of a scraper arch breaker relies on well-coordinated core components, each performing its respective function to jointly ensure the efficient and smooth discharging process. High-quality scraper arch breaker components are essential for long-term equipment reliability.

Drive System: With a motor as the power source, it provides continuous and stable driving force for the equipment to ensure no jamming in the transmission link. Equipped with high-precision gear components made of high-quality alloy materials, it features high transmission efficiency and low wear rate, which is crucial for the long-term operation of the scraper arch breaker.

Bearing and Conveying Structure: It consists of two core parts: the shell and the scraper. The shell is made of SUS304 stainless steel, which has high material density and strong corrosion resistance, and can meet the contact requirements of materials with different properties such as chemical raw materials and food powders, avoiding material contamination and equipment rust. The scraper is customized according to material hardness and fluidity, and its surface is subjected to wear-resistant treatment, which ensures the arch-breaking effect while extending its own service life. SUS304 stainless steel scraper arch breakers are ideal for food and pharmaceutical industries.

Auxiliary Structure: The equipment adopts an overall design without redundant bolts, which not only simplifies the assembly process but also reduces the "dead corners" of material accumulation, lowering the difficulty of cleaning and maintenance. Some models can be equipped with sealing components as required, making them suitable for material scenarios with easy dust generation and volatility. Sealed scraper arch breakers are perfect for handling volatile materials.

Working Process of Scraper Arch Breaker:

Scraper arch breakers are usually installed at the bottom of silos and accurately connected to silo outlets. The specific working steps are as follows. Proper installation of scraper arch breakers ensures optimal discharging performance.

Material Inlet: The powder and granular materials stored in the silo naturally fall into the feeding area of the scraper arch breaker under the action of gravity, forming a stable material supply. Scraper arch breakers ensure consistent material flow for continuous production.

Power Transmission: After starting the motor, the motor drives the gear components to operate, and transmits power to the scraper structure through gear meshing transmission. The high-precision gear transmission of scraper arch breakers ensures smooth power delivery.

Arch Breaking and Discharging: Driven by gears, the scraper makes uniform circular motion along the inner wall of the silo. During the movement, the scraper directly acts on the materials at the bottom and side walls of the silo, breaking the "bridging" (materials form an arch structure in the hopper, hindering falling) and "hollowing" (materials in the center of the silo fall while materials around remain) phenomena caused by adsorption force and electrostatic force between particles, forcing materials to fall evenly into the discharging channel and completing stable conveying. Efficient arch-breaking of scraper arch breakers improves material utilization rate.
