Heavy-Duty Primary Crusher Dust Collection & Suppression System - LEFILTER Mining Solution
Product Introduction:
The LEFILTER system for primary crushers is engineered to withstand the most punishing conditions at the mine face. We offer a modular, hybrid approach that can combine high-pressure, low-volume mist suppression at the feed hopper and discharge point with a robust, high-airflow baghouse filter for airborne control. Our baghouses are constructed with abrasion-resistant steel (AR400 lining at inlets), reinforced structural supports, and feature heavy-duty, pulse-jet cleaning systems powered by industrial-grade compressors. The filter bags are specifically selected from abrasion-resistant materials like polypropylene with a hardened surface treatment or woven polyester, designed to endure the relentless assault of sharp, coarse rock dust. The entire system is built for minimal maintenance and maximum uptime in remote, dusty locations.
Application Area:
This solution targets the initial size reduction stage at open-pit mines, quarries, and aggregate plants, where primary jaw or gyratory crushers process run-of-mine ore, limestone, or granite. The action of dumping massive rocks and the subsequent violent crushing generates enormous clouds of respirable crystalline silica (RCS) dust, along with coarser particles. This dust creates immediate hazards: it obscures visibility for operators, poses a severe silicosis health risk, accelerates wear on all nearby machinery (bearings, engines, electrical components), and can lead to environmental non-compliance through off-site drift. Controlling dust at this source is the most effective way to protect personnel, assets, and community relations.
Our Solution:
LEFILTER provides more than just equipment; we deliver a site-specific dust management strategy. For arid climates, our engineered baghouse systems include pre-separation chambers or settling ducts to knock out the heaviest fraction before filtration, protecting the bags. We design effective capture hoods and enclosures around the crusher to contain the dust cloud at its origin. For applications where water is available and suitable, we integrate precise fogging systems that use ultrasonic or air-atomizing nozzles to create optimal droplet sizes for dust agglomeration without over-wetting the material. Our solution focuses on reliability and ease of service, with components accessible under tough conditions. The result is clearer air, safer operations, extended equipment lifecycles, and assured compliance with MSHA, OSHA, and environmental regulations.
