Lagging of the conveyor pulley is essential to improve conveyor belt performance. The use of lagging reduces belt slippage, improves tracking and extends life of belt, bearing & other components.TEGA Ceramic Pulley Lagging is especially suited for pulleys with slippage and excessive wear & tear problems which make normal rubber lagging ineffective. Tega ceramic pulley lagging is widely used on the drive pulleys and can also be used on snub, bend and tail pulleys. This innovative new product incorporates square ceramic tiles with unique circular nubs which help in proper grip of the belt under wet muddy or any such arduous conditions.

Polyurethane liners are a synthesis of polyols & isocyanides chain extended or cross linked into giant molecular complexes. This material has combined properties of rubber as well as plastic.Polyurethane wear plates are normally steel backed plates where steel is bonded with polyurethane available in customized sizes. The backing steel prevents fines to penetrate behind the liner plate hence preventing bulging of the liner which otherwise causes liner dislodging. They are harder material compared to rubber but softer than plastic and provide an excellent degree of abrasion resistance together with flow ability.

A revolutionary idea and a great deal of entrepreneurial spirit: In 1975, Hans-Otto Schwarze used this combination and founded HOSCH.

Bulk solids, particularly fines when stored in hopper bin silo, do not flow smoothly resulting in phenomenon like rat holing, bridging, arching. Air Blaster when used alongwith suitable liners, prevent blockages and buildup in critical applications. Generally these clogging can be removed by the liners itself. However in case of inadequate hopper half angle and opening or discharge area (diameter or diagonal); the blockages become critical where the blasting system is employed as an aid to the liners. specified quantity of compressed air at 4-8 bar (60-120 psi) is released in a few milliseconds into the bin, at the position of the blockages. The impulse of the blasting force (the energy released) overcomes the compressive strength of the material and thus, free flow is restored.

CN Bonding System :

This extra layer of specially developed rubber at the bottom of ceramic pulley lagging ensures higher bonding strength with rubber to metal surface of the pulley.

The Conventional impact idlers, sheathed in rubber sleeves or rings, are not always sufficient to absorb the impact energy of the heavy falling materials at the loading zone of the conveyor. The heavy Impact load often damage of the belt due to line contact. . The Idlers being a rotating part are also susceptible to damage and failure of bearings due to accumulation of dust and grime. The malfunctioning of these idlers cause frequent conveyor breakdown and require repeated maintenance. Tega JUMBO Impact Bed systems are designed to work in such adverse conditions by effectively dampening the impact of heavy materials. Being a non-rotating part JUMBO requires Zero maintenance thus decreasing downtime, increasing operational efficiency and lowering maintenance cost.
