Back filter or dust collector is one of the most common filtration systems used in industrial processes to separate dust and other airborne particles. The way the device works is that the air contaminated with dust is directed to the hopper of the device. At this stage, the air flow speed reduced, and then the dusty air is passed through the filter bag, as a result, dust and other particles with the air accumulate on the surface of the filters, and clean air is directed from the outlet chamber.
With many years of experience in production, this company has extensive capabilities in the field of preparing and distributing various types of dust filters, including industrial and traditional filters, and is trying to capture the relevant dust in the best possible way, resulting in oxide recycling and reuse. Also creating healthy and clean air.

To extract gold from electronic waste and mineral soils that contain gold and silver, it is necessary to build a furnace. Gold extraction furnaces are made in several models, the furnaces that are made in smaller sizes are made almost standing, which is called the Qal furnace, and the furnaces that are made in larger dimensions are mostly revolving or the same. A rotating furnace is made, which depends on the size of the furnace in each part where the furnace is charged with gold dust. In soil washing methods, the furnaces used are usually large-sized rotary kilns that can hold one to five tons of soil in each part.

The air flow of the pressure pipe is directed to the filter opening through the nozzles installed on it. Using the right nozzle leads to injecting the right amount of air. A venturi is also used in order to correctly direct the reverse pulse air flow into the filter and produce a uniform shock pulse.
Aluminum/plastic venturi (or trumpet) can be provided in different sizes to properly guide the air jet into the basket and bag and increase the life of the filter bag.

The most common industrial air dust collection systems have a filter bag. Sanat Shadabi Filter is a supplier of all kinds of filter bags to meet all kinds of industrial needs. Freshness filter bags with the highest quality and level of customization can be produced according to customers’ requests.

Centrifugal fan or centrifugal ventilator is a technique in which the gas flow is moved by centrifugal force. Centrifugal or centrifugal fans discharge air in the direction perpendicular to the axis of rotation of the propeller. As a general rule, this type of fan is used in high pressure ducted systems. The incoming air enters the fan parallel to the rotation axis of the propeller and moves radially towards the periphery of the propeller and the tips of the blades. At the same time as this movement, the air flow receives some kinetic energy, which leads to an increase in static pressure at the same time as the air flow slows down before entering the discharge path. Centrifugal fans have the ability to work in places where the air flow is dirty and has impurities or has high temperature. But the most important feature of these fans is their ability to overcome high static pressure drop in ducted systems
