Elevator drum NC-50

Norian Drum NC-50

The Norian drum NC-50 is a key kinematic element of the tension station of the loading boot, designed to ensure strict geometry of movement of the traction body in elevators with a capacity of 50 tons per hour. This driven unit performs the function of centering a multilayer rubber-fabric belt with a width of 300 mm, preventing its displacement during intensive scooping of the bulk mass and ensuring uniform distribution of traction force across the entire cross-section of the shaft. The precisely calculated design of the drum with a working width of 330 mm and an outer diameter of 505 mm guarantees stable passage of the belt without the risk of slipping or the occurrence of transverse oscillations even under maximum seasonal loads.

Design of the Norian Drum NC-50

Taking into account the specifics of the lower node of the elevator, where the shedding of part of the transported product is inevitable, the driven drum NC-50 is manufactured exclusively in a slatted design. Such an engineering configuration eliminates the formation of a solid contact surface with the inner side of the belt, allowing the bulk mass that could get between the traction body and the metal to pass freely through the internal space of the drum. This technical solution preveNC critical sticking of wet product to the shaft and also acts as a decisive factor for seed lines, as it completely eliminates mechanical crushing and injury to the grain, maintaining the integrity of the handled material.

Norian Drum NC-50 and Its Interaction with Other Parts

The design of the shaft of the Norian drum provides for its direct integration with screw tension mechanisms, which are symmetrically located on the outer sides of the boot housing. Longitudinal movement of the drum axis in the guides allows for rapid and high-precision adjustment of the working tension of the traction body, compensating for natural operational stretching of the belt. The coordinated work of the drum and the tension station enables maintenance personnel to set up perfect centering of the belt in the column, which negates the risk of lateral run-out, preveNC friction of the bucket edges against the inner walls of the boxes, and significantly extends the overall resource of the transport system.

Relying on strict industrial safety requiremeNC and maintenance regulations, the bearing supports of the tension drum NC-50 are structurally moved outside the working chamber of the boot. Physical separation of the friction zones from the internal space, where fine grain dust concentrates, is a critically important condition for compliance with explosion and fire safety standards at elevator facilities, as it completely eliminates heating of the internal environment of the elevator in case of critical wear of the unit. In addition, the external format of the bearings provides unhindered visual and instrumental control of their condition, and also significantly simplifies access for scheduled lubrication of the mechanisms during routine service stops, which allows for an absolutely safe reduction in the time of preventive work and minimization of overall downtime of the production line.

Norian Drum NC-50 and Production Standards of the Zavod Moroza

The manufacturing process of the Norian drum at the production facilities of the Zavod Moroza is based on the principles of precise spatial assembly with mandatory instrumental control of the alignment of the shaft and supporting elemeNC, which guarantees stable operation of the unit without the occurrence of destructive imbalance. The use of wear-resistant rolled metal and careful calculation of the kinematic strength of the structure provide the part with a high operational margin necessary to withstand constant static and dynamic loads in harsh modes of round-the-clock transshipment. Such an engineering approach allows the customer to integrate a geometrically verified and high-resource unit into their transport system, which will ensure uninterrupted operation of the entire grain cleaning or drying complex over many harvest seasons, reducing the risk of sudden emergency stops to an absolute minimum.

Based on extensive operational experience in the field of designing elevator transport, the Zavod Moroza offers both the manufacture of individual high-resource units, such as the driven Norian drum NC-50, and a more systemic approach to maintaining the operability of your technological lines.

The concept of modularity embedded in our equipment allows enterprises to carry out deep modernization of existing units through targeted integration of modern componeNC without the need for full replacement of the housing or supporting metal structures. The presence of our own service department ensures a full cycle of technical support for the facility, including the prompt delivery of the entire range of related parts and traction bodies from the enterprise's warehouses.
