rotary mobile trommel screen for sand gravel

Rotary gold trommel of five parts,which include hexagonal drum,rack,funnel,reducer and motor.After the broken stone into the drum,it is screened with the rotating of the drum,and on the other hand stones with large size move forward along the drums gradient,screened gradually through different screen.After screening the small stone falls into funnels of their own,and carried out manually or artesian sent to the finished pile.

portable trommel screen - mineral processing

Trommel screens are one of the oldest screening devices, their structures are very simple but yet with high sorting accuracy and efficiency. So they are still widely used in China and many other countries.Trommels can be made to deliver several sized products by using trommel screens in series from finest to coarsest such as the one shown; or using concentric trommels with the coarsest mesh being innermost.Trommels remain widely used in some screening duties, including aggregate screening plants and the screening of mill discharge streams. They are also used for wet-scrubbing ores, such as Bauxite, alluvial gold, diamond ores and etc.

Trommels are installed on a small angle to the horizontal or use a series of internal baffles to transport material along with the cylinder.When the feeding material enters the roller trommel, due to the tilt and rotation of the trommel, the material on the screen surface is turned and rolled, so that the qualified material (under-screen product) is discharged through the outlet at the bottom of the rear end of the roller, and the unqualified material (upper-screen product) is discharged through the discharge port at the rear of the trommel.Trommels can handle material from 55 mm down to 6 mm, and even smaller sizes can be handled under wet screening conditions.Although trommels are typically cheaper, vibration-free, and mechanically robust, they generally have lower capacities than vibrating screens since only part of the screen surface is in use at any one time.Trommels remain widely and often work with the screening of mill discharge streams. Tumbling mill (AG, SAG, rod, and ball mills) discharge streams usually pass through a trommel screen attached to the mill outlet to prevent grinding media scats from reaching subsequent processing equipment, and the case of AG/SAG mills, to extract pebbles to send to crushing stage.

The drum body of the drum screen is generally divided into several sections, depending on the specific situation, the screen holes are arranged from small to large, and the screen hole diameter on each section is the same.In order to improve the sorting accuracy and avoid the situation where small particles are screened out in the large-aperture screen section, the feeding materials must be fully turned in the trommel screen, and the movement speed of those materials cannot be too fast.Generally, the inner wall of the trommel is equipped with a flex plate. Its role is to raise the feeding particles so that particles with different sizes get as many opportunities as possible to contact the sieve hole.If the hole diameter meets the requirements, the particles can pass through the sieve and get sorted.Also, the trommel screen generally has a relatively strict installation angle, usually, this angle is 5. Of course, under actual circumstances, it can be adjusted as needed.

The screen hole is not easy to be blocked, the operation is stable, and the operation produced noise is low.Simple structure and easy to maintain.The sieving cylinder can be closed, which is easy to collect dust.A higher screening efficiency and longer service life can achieved by adapting a special screen.High screening efficiency.Good working environment.Low equipment noise.

The entire screening is designed in a sealed dust cover, which eliminates the flying dust during the screening process, thereby improving the working environment.The entire screening is designed in a sealed dust cover, which eliminates the flying dust during the screening process, thereby improving the working environment.During the operation of the equipment, the noise generated by the material and the rotating screen is completely isolated by the sealed dust cover, so that the noise cannot be transmitted to the outside of the equipment, thereby reducing the noise of the equipment.

LXS series sand classifier is a sand washing equipment, which was designed to provide bigger capacity and higher cleaning level than traditional sand classifier. The input materials max size can be 30mm. LZZG Screw Classifier Working Principle The solid particles are different in size and density, so the settling speed in the liquid is different. The fine ore particles float in the water and overflow. The coarse ore particles sink to the bottom of the tank and are pushed upward by the screw.

trommel screen maintenance and troubleshooting | lzzg

The shaftless trommel screen is mainly used for grading treatment of belt-shaped and entangled materials. It is used for the classification of refractory materials, coal, fertilizer, sand field stones, and the selection of coal, coke, white ash, placer gold, and other viscous materials to make the product structure more uniform to meet the production needs. Shaftless trommel screens are relatively more material-saving and have more room for screening materials. It is also easier to overhaul when the drum fails, so shaftless drum screens are also used very much. For example, it is used for pre-treatment of domestic garbage. It can screen out the required garbage. The advantage of shaftless is that it can avoid the entanglement of materials and the screening efficiency is relatively high. Operation and maintenance The trommel screen is reliable in operation and low in maintenance. The following points should be briefly noted during operation: 1. The drum screen must be turned on first, and then the feeding equipment should be turned on; the opposite is true when parking; 2. Before running, the fasteners of the drum screen should be inspected, and if loose, they should be fastened in time. In the future, the drum screen fasteners can be inspected and processed regularly (weekly or half-monthly); 3. The bearing seat and gearbox should be regularly checked for lubrication, and refueled and changed in time. The large shaft bearing adopts No. 2 lithium-based grease. Under normal circumstances, replenish the grease once every two months. The replenishment amount should not be too much, otherwise it will easily cause the bearing to overheat. Bearings should be cleaned and inspected once a year. 4. When the equipment is shut down for a long period of time (more than 30 days), the motor insulation should be shake-tested to avoid burning the motor. General troubleshooting Noise problems caused by loose bolts of trommel screen Solution: Re-tighten bolts or other fasteners; Wrong direction of rotation caused by wrong power cable connection of drum screen motor Solution: replace the power cable in the junction box; Click start delay problem caused by overload of drum screen motor or excessive delivery volume Solution: readjust the delivery volume; Inadequate ventilation or lack of lubricant in the drum screen box makes the gear box generate heat Solution: Check and adjust the heat dissipation of the vent and add lubricant; Drum screen motor heating problem Solution: 1. Reduce the load; 2. Tighten the connection; 3. Reconnect after checking. 4. Clean the heat sink of the motor; 5. Check whether the impeller of the drum screen fan is working properly to ensure smooth air circulation; Clogged screen holes prevent the drum screen from operating normally Solution: Clear the clogged garbage in time to reduce clogging.
