Hot selling CE approved trommel/Drum screen/sieve machine for plastic, quarry, recycling,coal,mine
Hot selling CE approved trommel/Drum screen/sieve machine for plastic, quarry, recycling,coal,mine is essential units which can apply in the mineral and solid-waste processing industries. It consists of a perforated cylindrical drum which is normally elevated at an angel at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material smaller than the screen apertures passes through the screen, while the oversized material exits at the other end of the drum.
Functions: configured for classification, screening, grading
Type: open type, closed type
Classification: shaft rotary screen, shaftless rotary screen
Construction: carbon steel, stainless steel
Applications Scope: widely used in chemical, coal, construction, gold mine, plastic,quarry,recycling, metallurgy, mineral-selecting industries, etc.
Hot selling CE approved trommel/Drum screen/sieve machine for plastic, quarry, recycling,coal,mine used to separate materials by size, for example, separating the biodegradable fraction of mixed municipal waste or separating different sizes of mulch or crushed stone. Production rates can be vary from 20 to 30 yards an hour to several hundred yards of material an hour based on number of factors described in this article.
Performance and Features:
Smooth operation, low noise,low energy consumption
Simple structure, convenient maintenance
Trommel screen sieve can be sealed designed, no dust pollution
Special screen mesh design, high screening efficiency, longer service life, less blockage
When material flow towards along the inclined rotating drum,materials jump and roll , the undersized material smaller than the screen apertures passes through the screen wire mesh, while the oversized material passes out at the other end of the drum.
There is one screen deck(we call it cleaning deck) with larger screen mesh under the first floor of screen deck,the cleaning deck is divided into many sections by some plates,there are some flexible balls in each section. When the gyratory screen is runing,these flexible balls will move along the motion tract and they will jump up and down after hitting the plates or the other balls. Then it will clean the first screen deck or break some large size material by its hitting.
The trommel screen screening quality is not good screening quality, the reason may be sieve clogged, sieve should be cleaned regularly; if the reason is screen surface damaged, just replace the screen surface; when the material moisture is higher, oversize is too thick, When it serious impact the screening process, you can considered increase the mesh to improve screening efficiency;
When the rotation rate of the trommel screen is not enough, mainly because the transfer belt is too loose, you should adjust the tightness of the transfer belt promptly, belt too tight or too loose will cause the belt easily shorten the service life of the trommel screen;
Bearing lack of oil, if the bearing working a long time without cleaning, can make bearing heating, bearings should be cleaned regularly, replace the seals, check the bearing greasing or oil quality meets the requirements; if the bearing wear seriously you'd better replace the bearings;
The shaft of trammel screen cannot turn up, check whether the seal sleeve is plugged, if so you just need clean up the sleeve;
The trommel screen gives out abnormal sounds during the operation, you should stop it immediately, check the screen tension, the bearing degree of wear, whether the bolted is loose and whether the spring is damaged.
