The trommel screen is a kind of machinery which is widely used in the separation technology. It is used to control the waste separation by the size of the particle size. The separation precision is high.The trommel of trommel screen is generally divided into several sections, depending on the specific situation, the sieve hole from small to large arrangement, each section on the sieve hole aperture the same.Trommel screen is composed of drive, screen frame, screen mesh, frame, sealing cover, inlet and outlet, etc.Our company Henan Excellent Machinery Co., Ltd. Uses the most famous brands domestically and internationally. Our suppliers include Siemens, ABB, Yintong, Wannan and so on.We use advanced tooling equipment including longmen planing and milling, vertical lathe, advanced automatic welding robot, etc. To ensure product quality.
A brief introduction.
The trommel screen is an imitation of the manual use of inclined screen sand working principle, the use of flat trommel screen cylinder, and ensure that the material flow in the screen cylinder within the circle of spiral blades can be continuous rolling screen more than five circles, so that the sand repeatedly roll, slide and fully discrete, separation;Different from the inclined rolling screen caused by the size of the material pushing each other, buried pressure, screening process in a hurry;Also different from the size of inclined vibrating screen material vibration, mixing.
Two. The main characteristics of the drum screen 1.Simple installation foundation: as the whole equipment is of box frame structure, only one flat ground is needed.The ground had better be hardened for easy cleaning.
2.High integrity: in addition to the finished material stowing belt machine, all the systems are integrated into a whole frame, which not only ensures the integrity of the equipment but also leaves a proper space for maintenance and inspection.Convenience and security.
3.Disassembly and transfer field is simple: the high integrity of the equipment is convenient for the construction site storage or transfer field transportation. The disassembly and assembly components are only the finished material piling belt machine. Loosen the fixing bolts and hanging wire rope at the bottom and plug the finished belt machine into the bottom of the frame.
4.Working reliability: the trommel screening system adopts the mixing principle of agitator, and the raw materials are subjected to continuous spiral blade rolling, pushing and mutual friction in the mixing cylinder, with strong natural reliability.
5.The trommel screen tube is set flat to ensure that the material flow is more than five rolls between the spiral blades of the sieve tube, so that the sand repeatedly rolls and fully separates and screens.Different from oblique rolling screen or oblique vibrating screen caused by the size of the material each other punching or anise-supporting small material vibration caused by incomplete screening, mixing phenomenon.
6.Economy of use:
The capacity of the hopper is up to 8M3, so that the loader can reasonably arrange the loading time of the main equipment (such as mixing station) and the trommel screen, avoid the loader in different loading points and frequent exchange of raw materials, the width of the storage hopper is larger than 3.2 meters, also make the loader easy loading, reduce the labor intensity.
(2) the screen can be replaced by a piece of connection, easy to wear after the replacement or change with different size mesh screen 3.Working principle of trommel screen
The entire device consists of raw material storage hopper, raw material feeding belt machine, flat screen mesh, finished product sand pile belt, abandoned stone and other components of the discharge chute, electric equipment operation after the raw material into the large capacity storage hopper by loader, raw materials through the feed belt into horizontal cylindrical screen, rotating sieve cylinder to drive the material inside the drum blade pushing and rolling forming raw materials in the sieve surface under the rolling effect of artificial sand screening, screening out the fg sand aggregate bin by dropping it on the finished burning on belt, and belt falling ascension is finished material heap, or directly into storage hopper, material classification clear, the whole process is continuous and accurate.
Four.The special function of drum sieve
1. The sand-beating device in the trommel screen cylinder can break up and break up clumps of sand.
2. The screen surface cleaning device installed on the rolling screen surface can clean the adhered sand by itself to prevent the mesh from being blocked
Note: These two special functions have specific effects on the high water and soil content of sand commonly available in the construction sand market.
Five.Characteristic parameters of trommel screen
Productivity: generally 50-150 tons/hour, regarding the mesh size, the productivity is high if the mesh size is large.The whole equipment power: refers to the raw material belt, the finished product belt, the rotary motor power sum.
Height of finished stock pile: this height is related to the volume of finished stock pile, the height of transportation vehicle and the height of storage hopper.Storage hopper capacity: the larger the capacity is, the less the loading frequency is, which can ensure that the forklift takes into account the mixing station.Other parameters: loading port width, dimensions, etc.
