A dust collecting system for a stone crusher plant is essential to maintain a clean and safe work environment, reduce air pollution, and comply with environmental regulations. This system efficiently captures and removes dust particles generated during the crushing process, ensuring optimal air quality around the plant.

Operations related to the extraction of mineral ore such as blasting, transportation, grinding, and crushing can release large amounts of dust into the atmosphere. This is particularly true in a crusher plant where the demolition of stones, an operation that generates vast amounts of dust, is a daily procedure.

Dust can generate a series of problems for industrial operations. Not only can dust cause health problems, but it can also reduce the productivity of a mining site by limiting visibility and increasing wear-and-tear on equipment. 

What is crusher dust?

Crusher dust is a type of fine dust, which contains very small 0-5mm aggregate particles as well as sand. It is formed as a by-product from mining operations and is often recycled for different applications such as construction. 

Whenever rocks are crushed by rock crushing equipment, tiny PM 1, PM 2.5 and PM 10 dust particles spread through the air. This by-product of rock crushing may cause harm to the health of workers and nearby communities and damage the durability of equipment, leading to bearing failure, lubricant contamination, and increased risk of fire autoignition.

Particles coming from high compressive strength rocks (hardness), with a higher mosh index and angularity (sharp edges) cause the greatest damages, such as silica, quartz and diamond dust. 

Health effects of crystalline silica

Silicon dioxide, also known as silica, is a chemical compound commonly found in quartz. Silica normally presents itself in a crystallized form, and it is a component of sand in various parts of the world. Industrial uses of silica include the manufacturing of microelectronics and structural materials. Some living organisms, such as grass, use silica as a defense mechanism to drive off herbivores.

Breathing dust particles from crystalline silica can have scathing effects on a person’s health. Airborne dust can stay lodged inside the lungs, causing inflammation and scarring on lung tissue. This condition is known as silicosis and can result in permanent lung damage or even the death of the patient. 

Chronic silicosis can occur after periodic exposure to silica dust, but exposure to large amounts of dust can drastically hasten the development of the condition. Even after exposure to dust is discontinued, silica dust particles can remain in the lungs for prolonged periods of time. 

Symptoms of silicosis include: 

• Cough
• Fatigue
• Shortness of breath
• Chest pain

Silica dust from stone crushing can be a major factor in a person developing silicosis, leading professionals to catalog it as an occupational lung disease. Complications from developing silicosis can also cause patients to develop more serious diseases. 

Examples of other serious diseases caused by silica and other airborne dust exposure include:

• Tuberculosis
• Lung Cancer
• Chronic Obstructive Pulmonary Disease (COPD)
• Kidney Disease
• GPT Dust Collectors can monitor airborne dust levels by using state-of-the-art measurement technologies. Alongside solid methodologies supported by years of research and development, the Pulse Jet Dust collector technology can be used to assess dust levels in the atmosphere under different environmental conditions. Using this data, you can determine which extraction method can best ensure mine safety while guaranteeing competitive mining operations.
