In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 'pit', and,Industrial Dust Collectors and Dry Material Handling Valves,Pre-filters or Point of Use – Increase baghouse efficiency and decrease maintenance or local dust collection. Compact and Mobile – Fits where traditional units can’t. Horizontal options are available as well! Tough Dust Specialists – Abrasive, sticky, fibrous, hygroscopic, heat up, cool down, etc. Material Recovery – Help save the environment and the pocketbook.Industrial Mining Equipment & Machinery | General Kinematics,Mining machines are now more efficient because updated technology saves energy and reduces the number of harmful chemicals needed to extract desired material from its surroundings. Heavy duty, weather-resistant equipment is still necessary to extract, transport, and process minerals, ores, coal, and precious metals from soil, sand, and rock.
