Structure

Trommel drum sieve main motor, reducer, roller units, racks, closures, expected out components.

Edit this paragraph works

Roller means mounted on the frame inclined. After the drum motor reducer are connected together by coupling means, the drive roller means rotatable about its axis. When the material into the drum means, the inclination and the rotation of the drum means, so that the material inverting and rolling the screen surface, so that qualified materials (the undersize product) through the discharge opening at the bottom of the rear end of the drum is discharged, unqualified material (sieve product) by the end of the drum discharge discharge port. As the material within the drum flip, scroll, so that the material in the meshes of the card can be ejected, to prevent clogging of the sieve. Drum sieve sand, the principle of construction drum trommel screening machine with almost the same, there are differences on the people know it and it is called.

Main features

Trommel

A sieve clogging.

2 running smoothly, low noise.

3 simple structure, easy maintenance.

4 sieve tube can be closed, easy sealed collecting.

5 whole high reliability, low one-time investment.

6 using a special screen, high efficiency, long service life.

Edit the scope of this paragraph

I. large gravel quarry for grading. And isolated dirt and powder.

II. Isolation and sand with gravel field.

Three coal industry for lump coal and coal washing and separation (part of washing machines)

Four. Chemical industry, mineral industry for size classification and separation of lumps powdery substance.

Equipment Installation

1, the embedded steel. Embedded steel requirements, require embedded steel shall be on a plane to install equipment before installation diagram is located on the same plane. Install the required embedded steel, bolts and other foot units owned by the installation.

2, the sieve installation. According device inlet, discharge port positions arranged on the sieve to determine the installation location.

2, installed base bracket. The ends of the sieve by lifting the bracket mounted on the base, and the mounting angle of the screen to adjust the angle of the design, and finally fixed welding.

3, connecting the inlet and outlet ports.

4, connecting the lower bracket seal sieve plate.

5. Rotate the drum sieve drum, without too much resistance or stuck phenomenon, or should be adjusted promptly find out the reason.

6, after the factory drum sieve, if more than six months before the installation, before the installation must be cleaned shaft bearings removed, inject new grease (lithium grease on the 2nd).
A), the preparatory work prior to commissioning

1, trommel various components installed, after passing the examination, you can make a trial run. Before commissioning, should be carefully checked each component is installed correctly as shown by the drawings, each fastener securely, whether there is prejudice surrounding sieve drum sieve run an obstacle;

2, the rectangular access door in an open position, and rotate the cylinder manually sieved jigger, observe the presence or absence of comb-shaped ballast cleaning mechanism made card, the friction phenomena, if any can be adjusted by adjusting bolt;

3, check the bearing, gearbox should be oiled, gearbox oil level should be appropriate;

4, the power connector should be solid and reliable, good insulation, properly grounded.

Two), no-load test

1. Jog motor control button to check the motor turning the cage should be shown consistent trommel steering;

2. Start equipment operation 4--6 hours to observe the operation of the drum sieve, if found abnormal sound or other phenomena, should be down to check, identify the causes and troubleshooting.

Commissioning 4-6 hours should check the following items:

a, shaft bearing temperature, the maximum temperature does not exceed the requirements of 75 ℃, temperature does not exceed 45 ℃.

b, around the fastening bolts fastening, found loose should be tightened.

Three), feeding

1, in the screening machine is in steady state operation, start feeding and discharging equipment, put to trial;

2, after the normal discharge is sealed from the cover closed (normal operation, the cover shall remain sealed from the closed position);

3, check out the feed materials and dust particle size and a seamless situation;

4, running half an hour, for each component carefully checked and found problems in time.

5, the working process should always check the operation, if found not operating properly or abnormal sound, should be down to check to find out the reasons, troubleshooting

Operation and Maintenance

Cage drum sieve reliable, low maintenance, running in a few points below should be noted summarized as follows:

1, you must first open the cage while driving drum sieve, and then on feeding equipment; stopping the contrary;

2, three days before the run to the cage every day to check trommel fasteners, if loose should be tightened. After you can regularly (weekly or half) for Cage trommel fastener inspection and treatment;

3, bearing, gearbox lubrication should be checked regularly and timely refueling and oil changes. Shaft bearing lithium grease on the 2nd, under normal circumstances, once every two months grease filling, add the amount should not be too much, otherwise easily cause bearings to overheat. Throughout the bearings should be cleaned once a year to check.

4, the device stops for long periods (more than 30 days) to respond to restart the motor insulation shake test performed to avoid motor burn.
