The rotating drum screen in the garbage sorting assembly line system is generally installed in the upstream of the municipal solid waste sorting system, and effectively screens the municipal waste of different sizes. They have the function of dividing the incoming waste stream into two waste streams or multiple waste streams. According to the different particle sizes of the garbage components, the garbage components entering the trommel can be separated. The garbage drum screen is screened according to the diameter of the different attributes of the materials to be screened. It can be designed into a circular screen cylinder and an inner hexagonal screen cylinder, which can increase the function of primary bag breaking effect and has a self-cleaning function.

Performance characteristics of garbage drum screening machine:

1. Using the rolling conveying principle, the friction coefficient is small, the abrasion is light, and the screen holes are not easy to be blocked.

2. The roller support adopts an integral through-shaft structure, which runs smoothly, does not vibrate, and has low noise.

3. The internal drum screen fittings adopt split design, with simple structure, quick and convenient replacement and maintenance.

4. The drum body adopts an effective fully sealed structure, which does not raise dust or pollution.

5. Reliable operation, adopts deceleration transmission, high transmission efficiency, low power consumption, low energy consumption, and obvious energy saving effect.

6. According to customer requirements, different screen materials, screen hole sizes, high screening efficiency, long service life, and low maintenance costs can be used.

working principle:

The trommel is to sort waste by the hole size of the long drum. Different sizes of holes sort different types of materials (less than 80mm inertness to sand, broken glass, ceramics and stone, 80mm to 200mm for recyclable plastics, and 200mm to 300mm for paper and large plastics). The parts with a size smaller than the diameter of the screen mesh fall to the bottom of the machine, and the parts with a size larger than the diameter of the screen move forward above the machine. When moving, they fall into the discharge hopper along the in and out direction and are discharged to the surrounding The environment is better.

The drum screen of our company is composed of a solid steel frame (section steel) and a drum shell. The drum shell is also equipped with corresponding track plates for feeding, residue and screening parts. The hood can prevent dust from escaping, and can also be used to connect the dust collector provided on site. The center of the screen cylinder is the rotating drum. The drum body is made of steel plate and section steel. The drum body has been welded and equipped with running rims for its guidance and support. The drum body is driven by friction wheels to ensure quiet operation and reduce the operating requirements of the running ring.

All the contact surfaces of the drive, support and guide wheels are plastic coated. Even at higher speeds, they can run the screen smoothly, and all drive, support and guide components have a long service life. The rotating drum is radially supported on 4 wheels. Two wheels are used as driving wheels and are equipped with gear motors. The other wheels are used to support the drum and rotate freely. All the wheels radially called the support rollers are arranged in series. The diameter of all wheels varies from 300-500 mm and the width is approximately 140 mm. The roller is guided axially between the axial wheels, similar to the main wheel, with a plastic-coated running ring. The main support bearing is of high quality and moderate size, which ensures the service life of the screen.
