Worm conveyors
Worm conveyors are designed for conveying dusts, loose, powder and fine particle materials. They are used for transporting bulk materials vertically or slantwise. They may receive the transported material from underneath the hoppers, unloading bin, tanks or other conveyors and feed it to other devices and containers.
As a standard, the worm conveyors serve for transporting materials having the temperature up to 200 ̊C (special versions facilitate higher temperatures).
ECO INSTAL offers a wide range of conveyors, both in terms of size and the type of conveyed materials. As a standard, we offer U, V and D-type trough conveyors. In practice, the most often produced conveyors are 200 mm and 250 mm conveyors. The scope of our production encompasses 1,000 mm diameter conveyors.
Depending on the type and quantity of the conveyed material, the maximum length of conveyors may amount to 20 m for a single drive and 40 m for a double drive. The dimensions of inlet and outlet connections may be of custom, depending on the customer requirements. The conveyor is made of a worm shaft with a bearing, enclosure and a drive unit in the form of a motor gear. The size of the motor gear, motor rate power, rpm etc. of each conveyor are selected on the individual basis. The type of the construction material, trough thickness, worm blade thickness (type of blades – full, band etc.), helix stroke, worm shaft diameter are selected so as to provide the longest possible life of the equipment.
The trouble-free operation of conveyors is guaranteed by the special bearing design of the worm shaft. The outlet of the worm shaft is sealed by means of glands with a sealing cord. In the case of long conveyors, special intermediate bearing design along the conveyor is applied. For the sugar industry, ECO INSTAL offers intermediate bearing design with the use of Cooper split bearings.
Upon the customer’s request, the conveyors may be equipped with:
- conveyor inlet closing devices (dampers, valves etc.),
- motor-gear motors or inverter-fed motors,
- conveyor speed sensors,
- conveyed material cooling or conveyor thermal isolation.
U-type conveyor
- In this version, the conveyor trough is made of U-shaped sheet. This type of conveyors is designed for horizontal or slightly slantwise conveying. The standard offered conveyors include U200 and U250 models. The entire offer comprises the conveyors ranging from U100 to U500. Upon the customer request, larger conveyors may be built (U600, U800, U1000).
It is worth mentioning that the trough conveyors facilitate easy inspection of the worm shaft condition, since the entire trough is enclosed by an opening cover.
V-type conveyor
- In this version, the conveyor trough is made of V-shaped sheet. This type of conveyors is designed for horizontal conveying. These conveyors are mainly used where wide hoppers are installed and it is not necessary to use a large conveyor (these include e.g. filter bag hoppers). The standard offered conveyors include V250 and V500 models. Upon the customer request, other conveyor dimensions may be provided.
D-type conveyor
- In this version, the trough takes the form of a tube (typical tube or a tube made of steel). This type of conveyors is designed for horizontal or any slantwise conveying. The standard offered conveyors include D100 and D500 models. Upon the customer request, larger conveyors may be built (D600, D800, D1000).
ECO INSTAL may also produce various types of worm shafts or worm blades in accordance with the customer documentation.
