The mobile trommel sand screening machine is based on the working principle of artificially using an inclined screen to screen sand. It adopts a flat trommel drum, and ensures that the material flow can be continuously rolled between the spiral blades in the sieve drum for more than five circles, so that the sand can be screened continuously. The materials are repeatedly tumbling and sliding to be fully dispersed and separated; it is different from the mutual pushing and burying of the large and small materials caused by the inclined tumbling screen, and the screening process is rushed; it is also different from the inclined vibrating screen.

Working principle of mobile trommel sand screening machine:

The mobile trommel sand screening machine is driven by a cylindrical device through a transmission system, and rotates at a certain speed. The materials are turned and rolled in it, and are separated from the top to the bottom through the screening drum. The fine materials are discharged from the lower part of the front end of the screening drum, and the coarse materials It is discharged from the tail of the lower end of the screening drum, and the sieved debris is discharged from the discharge port. Due to the overturning and rolling of the material in the drum, the material stuck in the sieve hole can be ejected, which effectively prevents the sieve hole from being blocked. It overcomes the screen clogging problem of the original vibrating screen and linear screen when screening wet materials, and improves the output and reliability of the screening system.

Structure of mobile trommel sand screening machine

The mobile trommel sand screening machine is composed of a drum, a motor, a reducer, a frame and other mechanisms, and the whole machine is inclined.

Features of mobile trommel sand screening machine:

1. The installation foundation is simple: because the entire equipment is a box-shaped frame structure, only a flat ground is required. Hardened floor for easy cleaning.

2. High integrity: Except for the finished material stacker belt conveyor, all systems are integrated into an overall frame, which not only ensures the integrity of the equipment but also leaves a moderate space for maintenance and inspection. Convenience and safety.

3. Easy disassembly and assembly and transfer: The high integrity of the equipment is convenient for storage or transportation at the construction site. The disassembly and assembly components are only the finished stacking belt conveyor. Loosen the bottom fixing bolts and hanging wire ropes, and insert the finished belt conveyor into the main frame. The bottom can be.

4. Working reliability: The core screening system adopts the stirring principle of the mixer. The raw materials are tumbled, pushed and rubbed by the continuous spiral blades in the mixing drum, and the effect is strong and reliable.

5. The roller screen drum is placed horizontally, and the material flow is rolled and screened more than five times between the spiral blades of the screen drum, so that the sand material is repeatedly rolled and fully dispersed and screened. It is different from the incomplete screening and mixing phenomenon caused by the mutual crushing of large and small materials or the vibration of large and small materials caused by inclined rolling screen or inclined vibrating screen.

1. Wide material adaptability:

The trommel screen is used for screening all kinds of materials, whether it is inferior coal, coal slime, or bituminous coal and other materials, it can be screened smoothly.

2. The feeding method is simple and diverse:

The feed port of the drum screen developed by our company can be designed according to the actual site. No matter it is a belt, a funnel or other feeding methods, it can feed smoothly without taking special measures.

3. Diverse screening:

The trommel can be equipped with a comb-type cleaning mechanism. During the screening process, no matter how dirty or miscellaneous the material enters the screening cylinder, it can be screened, thereby improving the screening efficiency of the equipment.

4. The trommel screen has a large weight and is easy to be large-scaled:

Under the same size, the area of the circle is larger than that of other shapes, so the effective area for sieving is larger, so that the material can fully contact the screen, so the sieving weight per unit time is larger. Because of its simple structure, convenient layout, novel and mature technology, it is easy to be large-scaled.

5. Low energy consumption of trommel:

The trommel screen motor developed by our company has low power, two to three points of other screen types. It processes the same amount of material and the running time is only two points of other screen types, so the energy consumption is low.

6. The trommel screen has a 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, and avoids pollution to the working environment.

7. The drum screen has low noise:

During the operation of the trommel screen, due to the low speed of the rotary screen and the sealing isolation cover to isolate it from the outside, the noise cannot be transmitted to the outside, thereby reducing the noise of the equipment.

8. The trommel has a long service life and low maintenance:

The trommel screen is composed of several ring-shaped screens, and its total screening area is much larger than that of other screen types. The equipment runs for a short period of time, so it has a long service life, few wearing parts, and low maintenance.

9. Convenient for drum screening and maintenance:

The upper cover of the trommel screen can be disassembled, and the normal operation of the machine will not be affected after disassembly, and the maintenance is very convenient.
