En-masse conveyor: The “Customized Equipment” for Bulk Material Handling in the Paper-making Industry

Optimizing Bulk Handling Efficiency While Meeting Paper Industry’s Hygiene & Durability Standards

In the production chain of the paper-making industryfrom the pre-treatment of raw materials such as wood and waste paperto the fiber conveying in the pulping processand then to the recycling of paper edges and waste residuethe continuity and stability of bulk material handling directly affect production efficiency and cost controlThe En-masse conveyor, as a “closedlow-loss” conveying devicehas gradually become one of the core equipment for bulk material turnover in this industry due to its adaptability to special materials in the paper-making industry (such as wet fiberspaper residueand wood chips).


The Characteristics of Bulk Materials in the Paper-making IndustryWhy Choose En-masse conveyors?

Firstit is necessary to clarify the “special nature” of bulk materials in the paper-making industry—these materials often have the characteristics of high humidityeasy adhesionand complex compositionTraditional conveying equipment (such as belt conveyors) is prone to problems such as“material spillageequipment blockageand difficult cleaning.”

Specificallythe core bulk material types and pain points in the paper-making industry include:


• Wood chips/Bamboo chips (Preparation stage): Blocky materials that need to be conveyed from the raw material warehouse to the chipperTraditional conveying is prone to blockages due to material accumulationand open conveying is susceptible to environmental humiditywhich can cause mold growth.

• Wet fibers (Pulping stage): With a moisture content as high as 60%-80%these fibers are highly adhesiveOrdinary conveyors are prone to “wall adhesion and residue” which increases material loss and equipment cleaning costs.

• Paper residue/Waste paper edges (Finished product stage): These are fine and fluffy materials that easily produce dust during conveying and need to be recycledThe equipment must have strong airtightness to reduce waste.

• Lime powder/Talc powder (Auxiliary material stage): These powdered auxiliary materials are used for paper sizing and fillingThey easily fly around and pollute the environmentso closed conveying is required to ensure workshop hygiene and raw material purity.


The scraper conveyor is used for conveying wood chips.

The En-masse conveyor, with its structural design of “scrapers buried in the material and conveying along a closed trough” can solve the above pain pointsIts airtightness can prevent dust and material adhesionand the scraper’s forced pushing can handle high-humidityhigh-adhesion materialsmaking it a “customized choice” for bulk material handling in the paper-making industry.

Under the trend of cost reduction and efficiency improvement, green production in the paper-making industry, the application of buried scraper conveyors not only solves the problems of traditional conveying equipment such as “high loss, heavy pollution, and difficult maintenance,” but also realizes three core values:

Cost Optimization: The loss rate of raw materials (wet fibers, paper edges) is reduced, and the precision of auxiliary material conveying is improved, saving 10%-20% of raw material and auxiliary material costs for enterprises every year.

Efficiency Improvement: Continuous conveying from “raw materials-pulping-finished products” is achieved, reducing manual transfer links.The equipment failure rate is reduced from 8%-10% of traditional equipment to less than 2%, and workshop production efficiency is increased by 15%.

Environmental Compliance: Closed conveying reduces dust and odor pollution, lowering the risk of environmental penalties.
