Rotating arch breaker

Rotating arch breaker

The rotary arch breaker is a mechanical device specifically designed to solve the problem of material arching and bridging in silos, which leads to poor material discharge. It consists of a drive device, a rotating mechanism, a scraper mechanism, and a housing. The motor drives the reducer, which in turn drives the rotating mechanism. The rotating mechanism drives the scraper (or scraping blade, arch-breaking shaft) to perform low-speed circular motion along the inner wall of the silo (especially near the conical part or outlet). When the material forms an arch or bridge due to friction, adhesion, or particle characteristics, causing blockage, the rotating scraper/scraping blade/arch-breaking shaft forcefully cuts into and stirs the material, breaking the support and adhesive forces between the particles, directly crushing the agglomerates or breaking the arch structure. The crushed material regains fluidity under the action of gravity, enabling smooth material discharge. It is widely used in industries such as chemical, grain, mining, and building materials.

Product Introduction

      The rotary arch breaker is a mechanical device specifically designed to solve the problem of material arching and bridging in silos, which leads to poor material discharge. It consists of a drive device, a rotating mechanism, a scraper mechanism, and a housing. The motor drives the reducer, which in turn drives the rotating mechanism. The rotating mechanism drives the scraper (or scraping blade, arch-breaking shaft) to perform low-speed circular motion along the inner wall of the silo (especially near the conical part or outlet). When the material forms an arch or bridge due to friction, adhesion, or particle characteristics, causing blockage, the rotating scraper/scraping blade/arch-breaking shaft forcefully cuts into and stirs the material, breaking the support and adhesive forces between the particles, directly crushing the agglomerates or breaking the arch structure. The crushed material regains fluidity under the action of gravity, enabling smooth material discharge. It is widely used in industries such as chemical, grain, mining, and building materials.

Advantages and characteristics

  • 01?Efficient arch breaking: The mechanical force directly acts on the arching points, with strong ability to break stubborn bridges and agglomerates, and high efficiency.
  • 02Material range: powdered, granular, and viscous materials (such as PE powder, lime, grain, and chemical raw materials).
  • 03Material silo form: suitable for the bottom of various silo types such as conical tanks and square silos.
  • 04?Industries: food, pharmaceuticals (requiring stainless steel materials), chemical, light industry, mining, building materials, etc.
  • 05?Reliable operation: The large speed ratio reducer provides low-speed high torque, ensuring smooth and reliable operation. The structural design takes wear resistance and stress resistance into consideration, resulting in a long service life.
  • 06?High controllability: The speed is adjustable, adapting to different material properties and degrees of blockage. It can be linked with PLC to achieve timed start, inductive triggering, or manual control.
  • 07?Easy maintenance: Compared to pneumatic arch breakers (such as air cannons), the mechanical structure is relatively intuitive and maintenance is more convenient.
  • 08??Cost-effectiveness: Easy to install, effectively reduces manual poking workload and downtime losses, and enhances continuous production efficiency and economic benefits.?

Main types and design features

01Scraper/blade type arch breaker: The core is a rotating scraper or blade that scrapes and cuts the accumulated material and arches close to the silo wall. The structure is relatively simple, and the arch breaking is direct and effective.

02Rotating scraper arch breaker and discharger: often combining arch breaking and feeding functions (such as hollow feeding design). Emphasizes the use of slewing bearings to drive the large scraper assembly, achieving a wide arch breaking range.

03Double-broken arch shaft design: Utilizing two cooperating rotating broken arch shafts, it enhances the crushing capability for materials prone to arching, ensuring continuous conveyance.

04Tightness: Some models (such as the anti-arch spiral feeder) feature a pressure-resistant sealing structure, adapting to both positive and negative pressure environments and preventing dust leakage.

05Material diversity: The standard material is carbon steel, while stainless steel (SUS304/316L) is required for food and pharmaceutical applications. Special materials (such as titanium) can be customized to cope with highly corrosive environments.

Solution

The arch-breaking device can comprehensively address the following situations: arched bridging at the outlet of the silo, formation of a hollow in the silo, surrounding areas not discharging material, and material adhering to the walls around the silo;

  • 17534115063389356

Application areas:

It is primarily applied to materials that are prone to bridging and walling during feeding, such as silica, calcium carbide, titanium chloride, carbon, toner, ink, diatomaceous earth, glass fiber, fiber, paper scraps, wood chips, waste plastic fragments, dyes, pigments, coatings, tea residue, ash, dehydrated food, activated carbon, oil residue, dust, pharmaceuticals, pesticides, and citric acid;
