Mining and Dust Collection

Clean Air Matrix

RoboVent engineers are experts in every category of air filtration and ventilation. The four categories below represent the major options for treating your contaminated air. RoboVent has designed solutions for each of these categories and has manufactured air filtration systems of unrivaled quality.

For more information about these categories, see Indoor Air Quality 101.


Large blowers and air filtration equipment draw contaminated air from the plant (typically at the ceiling level), filter it and return it to the plant. This is a proven solution in plants welding large parts with overhead cranes. It reduces the haze in the air, resulting in a cleaner working environment, with no negative pressure or heat loss.


Air in the immediate area of the welding activity is captured in a hood system, then filtered and returned to the plant. This is the best solution whenever possible. It allows for a more flexible system and removes the smoke directly from the operator's breathing zone. There are many types of source capture, including overhead hoods, crossflow hoods, fume arms and fume guns, some of which work better than others.


Large exhaust fans draw contaminated air from the plant and exhaust it directly into the environment, typically through the roof or walls. This is a traditional method and often results in negative air pressure. Also, it is very difficult to climate-control your plant and the system may not work well in the winter.

Air in the immediate area of the welding activity is captured in a hood, sent through ductwork, and exhausted directly into the environment. This is a lower capital cost alternative to filtration, but tends to result in high operating costs and large, unsightly ducting systems that work less efficiently with modifications. It also results in negative pressure problems.

Introduction to Dust Collection in Mining

The mining industry has had a challenging few years. Fluctuating demand and a lack of financing have kept the industry mired in uncertainty. Issues like the impact of China and the world's changing energy sources have created further confusion. The news isn't all bad, however: a recent infrastructure bill promises more than $300 billion to transportation projects. The Fixing America's Surface Transportation Act (known as the FAST Act) was signed in late 2015 and should move the needle a little.

Whether mining is booming or busting, one thing is certain: industry professionals are more mindful than ever of the need for protecting health and safety. In particular, operators understand the importance of good air quality. They are also aware of recent changes in regulations that will likely affect them, including changes from both the Mine Safety and Health Administration (MSHA) and the Occupational Safety and Health Administration (OSHA). For example, in 2016 OSHA changed its rules surrounding silica dust, a move that will affect many mining operations. OSHA's new rule cuts the permissible exposure limit (PEL) by half. The new limit is 50 micrograms per cubic meter of air, measured as an 8-hour time-weighted average. OSHA estimates the new rule could prevent hundreds of deaths and illnesses. Many mining operators who deal with silica dust will be scrambling to meet this new regulation.


Dust Collection Challenges in Mining

Mining operations create significant amounts of dust and gasses. Many of these dusts consist of very small particulates that are respirable. If exposure to these respirable dusts reaches certain levels, workers’ health could be seriously threatened. Even a dust as common as silica can lead to serious health problems. Prolonged exposure can lead to silicosis, a serious disease caused by damage to the lining of the lungs. Acute silicosis can cause the lungs to become inflamed and fill with fluid, creating a medical emergency. Chronic silicosis develops with even low-level exposure over time, reducing lung capacity until sufferers need oxygen to survive.

Effective ventilation is important in mining, as well. Without these measures, dangerous gasses, such as methane, could accumulate and increase the risk of explosion. Other, seemingly benign gases, such as carbon dioxide, could accumulate, as well; while these gasses are not explosive or toxic in small quantities, operators know that they are dangerous if they accumulate.

Solutions for Dust in Mining

Mining operations require very particular solutions for their unusual situations. RoboVent has decades of experience designing and manufacturing dust collectors to fit this kind of need. For example, RoboVent’s Mobile series of dust collectors are built to move. No mining operation stands still, and neither can its air management equipment. These powerful mobile units can meet your airflow and filtration targets needed to protect workers and meet regulations.

The Fusion series of dust collectors is another option. These collectors can be customized to address any concern, while running efficiently and with less maintenance than other equipment.

RoboVent also offers a number of exhaust fans and make-up air systems. These units keep air moving using powerful blowers and advanced controls. In addition to being high-performing, RoboVent products are famously reliable, a necessity when safeguarding air quality in a mining operation. As always, RoboVent guarantees its products with the best warranty in the business.


Ventilation Solutions For Portable Weld Fume Extraction

Portable Weld Fume Smoke Extraction

These self-contained systems enable workers to capture weld fumes from any location. When production lines or welding cells must remain flexible, these systems safeguard workers, no matter the situation.

Carbon Black Dust Collection

Carbon Black Dust Collection

Carbon black is a fine powder used in the manufacture of many common products, such as tires. This powder is an inhalation risk tied to pulmonary and respiratory problems.

Pigment Dust Collection

Many pigments contain metallic compounds that give them brilliant colors. Unfortunately, some of those metals are quite toxic, and pigment dust can be dangerous.

Silica Dust Collection

Silica is used in countless industrial applications. A recent change in air quality regulations has made silica dust a pressing concern for many employers.

Talc Dust Collection

Talc Dust Collection

Talc is a naturally occurring mineral that crumbles into a very fine powder. While highly useful in manufacturing, this powder can easily become airborne.
