(mesh) is developed in recent years for mining mineral processing, grading, dehydration and other screening machines replace metalsieve (mesh) of a new product. Mainly used in coal, iron ore, copper, gold and other ores grading, screening, dewatering and other places, is one of the
components necessary shaker sieve structure by polyurethane are divided into four types: mosaic bolt Join layering connection screen hook connection.
For example, layering connection type: Please place the sieve screen surface, and then sieve the support beam to install. Should generally be in the screening
machine both sides of the upper sieve plate, along with the width under the direction of the appropriate material u type iron suitable distance strip drilling screw holes and then bolt and tighten the underlying support beam, so that prison sieve firmly set in the middle. Strip iron support beams and the contact with the sieve is best to use rubber (can use old hose) pad. Sieve the middle of the support beam above method can also be installed here.
If the sieve plate is not required to install, you may shake it up and down the screen surface, long-term friction and collisions with steel support Liangfa Sheng, will seriously affect the life of sieve.
Screen vertical and horizontal rules are made of high wear-resistant polyurethane, wire article contains. Life than traditional metal mesh 3-10 times higher. Unique structure, suitable elastic and plastic strength, it reduced the card blocking, while the second harmonic due to screen high-frequency vibration section, but also reduce the sticky block. Practical hole high screening efficiency.
Mesh with elastic tension on both sides hook, the overall light weight, good flexibility, easy to transport storage, installation and removal easy. Screen can effectively absorb the shock, reduce noise, improve the working environment.
1. wear-proof and long service life, its service life is 3-5 times than steel screen plate, and 5 times than usual plastic screen plate.
2. moisture-proof and non-clogging sieve mesh, it caused its heavy capacity, and is perfect for products of high moisture content.
3. light weight, it reduced the load of screen.
4. self-cleaning function.
5. little maintenance work.
COMPARED WITH RUBBER,PLASTIC
1. Urethanes have better abrasion and tear resistance than rubbers, while offering higher load bearing capacity.
2. Compared to plastics, urethanes offer superior impact resistance, while offering excellent wear properties and elastic memory.
