Vibratory Screens
Vibratory screens machinery refers to industrial equipment designed to separate, classify, or sort materials based on particle size using vibrations. These machines are essential in industries like mining, construction, food processing, recycling, and pharmaceuticals.
🔧 What It Is
A vibratory screen (also called a vibrating screen or separator) is a mechanical screening machine that uses vibratory motion to move materials across a screen surface. The screen has openings that allow smaller particles to pass through, while larger ones are retained on top.
⚙️ How It Works
A vibrating motor or exciter generates motion.
The screen deck vibrates, causing material to stratify (layer by size).
Fine particles fall through the mesh; coarse particles move along the surface.
🌀 Types of Vibratory Screens
Type Motion Type Best For
Linear Vibrating Screen Straight-line Dry powders, granular materials
Circular Vibrating Screen Circular Wet/dry bulk materials
Elliptical Screen Elliptical Sticky or moist materials
High-Frequency Screen Rapid vibration Fine particle separation, dewatering
Banana Screen Multi-slope High-capacity screening
Grizzly Screen Static or vibrating bars Pre-screening large rocks
🧪 Applications
Mining & Quarrying: Sorting ores, coal, and aggregates
Food Industry: Grading grains, spices, powders
Recycling: Separating plastics, metals, glass
Pharmaceuticals: Ensuring uniform particle sizes
Construction: Screening sand, gravel, and cement
💡 Why Use Them?
Efficient material separation
High throughput
Low maintenance
Customizable for different materials and capacities
They’re like industrial-scale sieves—only smarter, faster, and built to handle serious volume.
Durham (/ˈdʌrəm/ ⓘ DURR-əm, locally /ˈdɜːrəm/ listenⓘ)[a] is a cathedral city and civil parish in the county of Durham, England. It is the county town and contains the headquarters of Durham County Council, the unitary authority which governs the district of County Durham.[3][4] The built-up area had a population of 50,510 at the 2021 Census.[2]
The city was built on a meander of the River Wear, which surrounds the centre on three sides and creates a narrow neck on the fourth. The surrounding land is hilly, except along the Wear's floodplain to the north and southeast.
Durham was founded in 995 by Anglo-Saxon monks seeking a place safe from Viking raids to house the relics of St Cuthbert. The church the monks built lasted only a century, as it was replaced by the present Durham Cathedral after the Norman Conquest; together with Durham Castle it is a UNESCO World Heritage Site. From the 1070s until 1836 the city was part of the County Palatine of Durham, a semi-independent jurisdiction ruled by the prince bishops of Durham which acted as a geopolitical buffer between the kingdoms of England and Scotland. In 1346, the Battle of Neville's Cross was fought half a mile west of the city, resulting in an English victory. In 1650, the cathedral was used to house Scottish prisoners after their defeat at the Battle of Dunbar.[5] During the Industrial Revolution, the Durham coalfield was heavily exploited, with dozens of collieries operating around the city and in nearby villages. Although these coal pits have now closed, the annual Durham Miners' Gala continues and is a major event for the city and region. Historically, Durham was also known for the manufacture of hosiery, carpets, and mustard.[6]
The city is the home of Durham University, which was founded in 1832 and therefore has a claim to be the third-oldest university in England. The university is a significant employer in the region, alongside the local council and national government at the land registry and passport office. The University Hospital of North Durham and HM Prison Durham are also located close to the city centre. The city also has significant tourism and hospitality sectors.[7]
