Lagging thickness - minimum 3mm. Plain or Grooved pattern finish. Can be designed to meet severe abrasive conditions. Can be designed to withstand strong acids attack..

RUBBER SCREENS   CORIRUBBER ® Rubber screens comes in handy for dust control, weight reduction, corrosion resistance, easy to install and easily customizable.   Constant pounding of rocks and ore in quarries and mines shortens the life of the perforated plate or wire cloth screens. Impacting stones cause noise that is detrimental to both employees and the neighboring community. When screening rocks and other dry material plugging is another nuisance. Changing of heavy steel screens may require a crane or extra manpower.   Rubber Screen are ideal for handling the toughest and most abrasive materials such as crushed stones, gravel, coal, slag and etc. Rubber materials provide flexibility, strength, impact absorption, demonstrate, superior cut and tear resistance as well as extended life for reduced down time and facilitate fast and easy installation.   CORIRUBBER ® screens offer a practical, economical solution to such difficulties in applications that range from scalping to mid range sizing.   Rubber compounds used in screens are designed to reduce the coefficient of friction and to suit to the operating conditions where moisture content is high and blinding has been of major concern. Once installed, blinding is eliminated and screening efficiency is vastly improved.

  Elastomeric Bridge Bearing Pads is a block of vulcanized elastomers reinforced internally by one or several steel plates, chemically bonded during vulcanization. .   External Forces being supported   Elastomeric bearings permit the simultaneous support of the following loads :. Absorption of briefly applied external horizontal forces Horizontal movement in all directions through shear deformation. Rotation of the bearing surfaces around all axes Standard absorption of vertical loads.   Elastomeric bearings are made out of chloroprene polymer. These bearing pads are designed for used in bridges and other structures such as buildings as a vertical load bearing component. There are manufactured from high quality material with number of layers of steel plates depending on the type of bearings highly strong and extremely resistance to weathering, ageing with almost no influence from UV radiation and ozone. Neoprene bearing pads provide uniform transfer of load from beam to structure. They absorb vibration and prevent noise transfer. While reducing the destructive action of vibration between movable and stationery structural members. They permit beam rotation at the bearing point due to deflection or misalignment. May also provide for movement caused by normal expansion and contraction and concrete creep effects and shrinkage. These pads are extensively in bridge structures. These pads provide good resistance to traction, excellent failure strain and performs well with dynamic loads. It has good rear resistance, excellent resistance to aging and a very low load bearing creep rate. This makes it suitable for the requirements of bearings.     Laminated Elastomeric Bearings     Type A :   Single reinforcement Bearing (Not used in civil Engineering structure). Type B :   The definition for type B according to EN 1337-3 is ; this type has (n+1), reinforcement /metal and (n) elastomeric of constant thickness with perimeter at least 4 millimetres thick and the upper and lower faces with a nominal 2.5mm thickness of elastomeric. The tolerance is (-0 and +2).   Other Type B :   By definition these are different in that the upper and lower elastomeric coatings are thicker. This type of bearing is no longer straightforward reinforcement protected by elastomeric, but designed on the basis of required ability such as Elastomeric a Half Lamination or Passive Coating types.   Type C :   Elastomeric bearings with two external plates and threaded holes for use onmetal structures, or as an anti-lift device: in this latter case, suitable anchor bars must be fitted to the bearings for anchoring purposes.   Type D :   Elastomeric bearings with external plates and pins that connect to suitable steel plates in order to secure the bearing to the structure..   Type E :   Elastomeric bearings with two suitably etched external plates to facilitate the bearing’s bonding to the structure by way of vulcanisation.

these are available in two different sizes. The smaller size has a stud on one side while the larger one has no stud. Two numbers of these mounts are used as the rubber springs in each of the quickfoot corirubber ® - 503 mountings these can be loaded either in compression or in shear and withstand loads upto 1000kg in compression and upto 200 kg in shear. a time tested mount for isolating vibration from diesel generators, compressors, screens, blowers and other medium to heavy machines. These quickfoot mounts can absorb a combination of shear & compression loading. Installation can be made for most machines without bolting to the floor by using oil resistant friction pad supplied with the mount. low cost mounting arrangement which are easy to install either in compression or in shear. They come in different sizes with studs on both ends these mounts have threaded inserts at the top and have an elliptical base with metal reinforcement. They can be supplied in synthetic rubber such as neoprene* or nitrile, depending on the service conditions. It is used for generator sets as well as air handling units such as blowers, axial and centrifugal fans. Ribbed mounting base provide a non-skid surface. Mounts without rib at the top and bottom are also available with same load characteristics. these are similar to cylindrical mountings except for the concave rubber profile which permits greater deflection for a given load. These are used to protect sensitive electrical / electronic instruments / fittings from low frequency external vibrations. The bolts on either end promote easy installation.
