Small sawdust screening machine

Overview of drum screening machine:
Drum screen is a screening equipment that grades materials based on their particle size, also known as drum screening machine. Due to its simple process layout, it is widely used in product grading in industries such as mining, building materials, transportation, energy, and chemical. Commonly used in the grading and screening of medium and fine-grained materials to improve material quality. Haorui Machinery can professionally customize various models, specifications, and methods of high-efficiency drum screens according to different actual situations of users.
The structural characteristics of the drum screening machine:
1. Wide material adaptability: Suitable for screening various types of materials, even low-quality materials can be screened smoothly.
2. The feeding method is simple and diverse: the drum screen feeding port developed by Haorui Machinery can be designed according to the actual site, whether it is belt, funnel or other feeding methods, no special measures need to be taken, and the feeding can be smooth.
3. High screening efficiency: The equipment can be equipped with a comb type cleaning mechanism. During the screening process, no matter how dirty or miscellaneous the material entering the screening cylinder is, it can be screened, thereby improving the screening efficiency of the equipment.
4. Large screening capacity and easy to enlarge: At the same size, the circular area is larger than the area of other shapes, so the effective screening area is larger, allowing the material to fully contact the sieve, resulting in a larger screening capacity per unit time. Due to its simple structure, convenient layout, innovative and mature technology, it is easy to scale up.
5. Low self energy consumption: The drum screen motor developed by our company has a low power, which is half to one-third of other screen types. It can process the same amount of material while running for only half the time of other screen types, resulting in low energy consumption.
6. Good working environment: The entire screening cylinder can be sealed with a sealed isolation cover, which eliminates dust flying and block splashing during the screening cycle, avoiding pollution to the working environment.
7. Low equipment noise: During operation, the drum screen has a low rotation speed and a sealed isolation cover to isolate it from the outside, which prevents noise from being transmitted to the outside and reduces equipment noise.
8. Long service life: Low maintenance required. The drum screen is composed of several circular mesh rings, and its total screening area is much larger than that of other screen types. In addition, the screening efficiency is high, and the equipment has a short operating time, resulting in a long service life, fewer vulnerable parts, and less maintenance required.
9. Easy maintenance: When replacing the sieve plate, simply open the sealing cover of the machine body for easy operation. After the sealing and isolation cover of the equipment is removed, it does not affect the normal operation of the machine and makes maintenance very convenient.

The drum screening machine uses a variable speed reduction system to rotate the screening cylinder at a certain speed. The material is separated from top to bottom through the screening cylinder, and fine material is discharged from the lower front end of the screening cylinder, while coarse material is discharged from the lower tail end of the screening cylinder. The drum type screening machine runs slowly and evenly during use, with minimal impact and vibration, stable operation, simple installation, and sometimes even no specialized foundation is required. It can be directly placed on a flat ground or floor slab and under the silo. The drum type screening machine is easy to seal and collect dust, requires minimal maintenance, is easy to maintain, and has a long service life. It is also a commonly used equipment in refractory materials, coal, river sand grading, sandstone grading, chemical granulation, and pharmaceutical pellets.
