How to Solve the 3 Biggest Failures of En-Masse Conveyors in Chemical Processing

Author :

In the chemical industry, material handling is a constant battle against corrosion, clumping, and leakage. Whether you are transporting soda ash or abrasive chemical powders, the reliability of your en-masse conveyor (buried scraper conveyor) directly impacts your plant’s uptime and safety.

As a specialized manufacturer, we understand that "off-the-shelf" solutions rarely work for chemical plants. Below, we break down the primary pain points and the professional-grade solutions to keep your production line moving.

1. Combating Corrosion and Abrasive Wear

Chemical raw materials are often highly corrosive, and hard impurities can act like sandpaper on your equipment.

  • The Problem: Rapid thinning of the machine trough and scraper failure.
  • The Solution: We utilize 304 stainless steel or other corrosion-resistant alloys for core components. To extend the service life of the machine trough, we install wear-resistant liners on the internal walls. Controlling the chain speed to a reasonable range is also critical to minimize friction-induced wear.

2. Preventing Clogging and "Motor Stalling"

Uneven feeding or material clumping (especially with hygroscopic chemicals) is the leading cause of chain jamming.

  • The Problem: "Muffled" machines (stalling) and chain breakage.
  • The Solution: Prevention starts before the material enters the conveyor. We recommend installing screening and impurity removal devices to intercept foreign objects. For damp or clumping materials, pre-treatment is essential. Furthermore, integrating anti-clogging monitoring and automatic shutdown devices ensures that if a blockage occurs, the system stops before mechanical damage happens.

3. Solving Sealing and High-Temperature Safety Issues

In chemical processing, a leak is more than a mess—it is an environmental and safety risk.

  • The Problem: Material leakage at joints and component deformation in high-temperature environments.
  • The Solution: We reinforce all machine trough connections with specialized sealing strips. To maintain structural integrity during high-temperature operation, we prioritize rigorous material selection and tension checks to prevent heat-induced failure.

Professional Maintenance: The Key to Longevity

To maximize your ROI, your team should follow these strict operational standards:

  1. Empty-Load Testing: Always perform a test run before loading material to check the chain tension and safety interlocks.
  2. Load Management: Never start or stop the conveyor under full load (no-load startup only).
  3. The 1/3 Rule: Monitor scraper thickness regularly; once wear exceeds 1/3 of the original thickness, the scraper must be replaced immediately.

Reliable Conveying for Chemical Success

By combining 304 stainless steel construction, smart monitoring, and strict maintenance protocols, your facility can eliminate frequent downtime. Following these industry standards ensures a safer, more efficient, and leak-free conveying process.
