Modular polyurethane
Presentation
The modular system is a system created to facilitate assembly/dismantling of screening equipment, facilitating maintenance for operators.
Being smaller than a tensioned cloth, the module is lighter and simpler to implement. Indeed, the modular mounting system consists of assembling several modules, usually 1 meter long and 300 mm wide is standard, on a screen floor.
As polyurethane has a high elongation capacity, modular panels must be reinforced with steel inserts to ensure good mechanical strength but also to withstand the load presented by the materials to be processed.
To be mounted, these modules are manufactured with different finishes according to the mounting template selected by the customer. There are several on the market, the most common being the “WS 85” system, invented by a colleague in the 1980s. GIRON offers most existing mounting systems and our staff will help you choose the best solution for your facility.
GIRON has a wide range of meshes (W) to match the needs of its customers.
Standard range : (for any another dimension, please contact us)
- Square meshes : 3 mm ≤ W ≤ 150 mm
- Rectangular meshes : 4 x 10 mm ≤ W ≤ 27.5 x 61 mm
- Injected cracks : 2 x 11 mm ≤ W ≤ 1.5 x 11 mm
- Meshing: in a row or staggered
The modular T-key system is a GIRON patent, registered in the 1990s. The principle consists in blocking the various modules onto the chassis of the screen by introducing a T-key between each panel in the fixing rail slot.
This is one of the most effective solutions for simple, easy and fast mounting, mainly for its installation in tight spaces in a vibrating screen.
The rail mounting and T-key method produces a solid positioning of the panels while offering easy and effortless mounting and dismantling with a simple screwdriver. A notch is provided for this purpose for leverage. According to the height of the chosen T-key head, it can act as an integrated deflector, allowing the deviation of the products or water on the screening surfaces for the whole length of the module.
As the modules are manufactured with uprights on the sides, they are easily and automatically positioned in the rail slot thus benefiting from strong stability and avoiding any risk of falling between floors and fixing rails. These benefits significantly improve the working conditions of operators while reducing their risk of injury and their response time.
The modular batten system was developed in the 1980s. The principle consists in forcibly inserting the various modules onto the chassis of the screen by previously inserting a batten, using a mallet, into the fixing rail slot.
This is one of the most common solutions on the market.
The method of fixing with battens is used to solidly position the panels. Firstly, one of the sides of the module having a groove is inserted into the batten, and then the second side of the module is forcibly slotted into the next batten using a mallet.
Dismantling in this case consists of inserting a screwdriver or other tool into the meshes of the module to create leverage and remove it from the batten. Care should be taken not to damage the mesh, if the panels are to be reused.
The assembly/dismantling operations of the MIG system are quite challenging for maintenance teams, many of whom prefer the MGI-type T-key mounting system which is easier and faster to implement.
The modular system by clamping consists in blocking the various modules onto the chassis of the screen by clipping a polyurethane part, called “mouse”, “corner” or “clip” in a previously mounted hook in the fixing rail slot.
The clamping fastening method offers a solid position for the panels, which can no longer slide into the rails once in position. The module is positioned on the rails by overlapping the hooks at the level of the notches provided for this purpose. Then, using a mallet to knock it in the horizontal direction, a polyurethane corner is clipped onto the hooks. Dismantling is done by removing the few polyurethane corners using the mallet.
The corners act as deflectors, deviating products or water on the screening surfaces and restricting the flow on the solid areas.
The assembly/ dismantling operations of the MMG system are relatively basic and quick for maintenance teams, but many still prefer the T-key assembly MGI type system due to the weight of polyurethane panels and the number of corners needed.
