Scraper Conveyor

Scraper Conveyor

The scraper conveyor is a continuous transportation equipment that transports bulk materials with the help of a moving scraper chain in a closed giant cross-section shell; because when transporting materials, the scraper chain is completely buried in the material, so it is called For buried scraper conveyor.

According to the layout and structure of the scraper conveyor chute, it can be divided into two types: parallel type and overlapping type. According to the number and layout of chains, it can be divided into four types: single chain, double-side chain, double center chain and triple chain.

Advantages of Fertilizer Scraper Conveyor

  1. Solid structure. It can withstand external forces such as impact, collision, smashing, and pressing of coal, gangue, or other materials.
  2. It can adapt to the needs of the uneven bottom plate, bending, and displacement of coal mining working face and can withstand vertical or horizontal bending.
  3. The machine body is short and easy to install.
  4. It can also serve as the coal mining machine operations track.
  5. It can run in reverse, which is convenient for handling bottom-chain accidents.
  6. It can be used as the fulcrum of the front section of the hydraulic support.
  7. The structure is simple, and the material can be fed or unloaded at any point on the conveying length.
  8. The casing is closed to prevent dust from flying and polluting the environment when conveying materials.
  9. When there is no casing at the tail, and the scraper is inserted into the material pile, the material can be taken and conveyed by itself.

Scraper Conveyor Applicable Materials

Horizontal transportation of fertilizers

Scraper conveyors can be used for horizontal transportation as well as inclined transportation. When transporting upward along an incline, the coal seam inclination should not exceed 25°, and when transporting downward, the inclination should not exceed 20°. When the coal seam inclination is large, an anti-skid device should be installed. Bendable scraper conveyors allow 2° to 4° bends in the horizontal and vertical directions.

Frequently Asked Questions

1. Installation: After the machine arrives at the factory, it will be installed in conjunction with the process, indicating the elevation and horizontal position, tilted installation, generally tilted at 2-5 degrees (which can be adjusted to make the user’s needs), and the machine bracket and transmission frame even ground angle holes, which can be mounted on rolled condensed soil.

① machinery each base and the foundation between the pad into the deed-shaped mat board thickness should not be greater than 30-35mm;

② the height of the base with the deed-shaped pad to adjust the height of the base to make the base 5 degrees of inclination;

③ After each base is adjusted properly, put the cylinder on the support and adjust the carrier wheel;

④ Install the drive part of the film wrapping machine;

⑤ Be sure that the bracket wheel, transmission device and cylinder are properly adjusted and start pouring cement, and after 8-10 days, start the no-load test run after the cement is solidified;

⑥ Method of adjusting the position of the machine body:

a. On the full length of the left and right sides of the machine body, install two parallel steel wires with a diameter of 0.5-1mm and check the level of the wires with a level meter;

b.Lower two phase hammers tangent to the rolling circle from each rolling circle down the sides of the dryer;

c.Measure the distance from the steel wire to the wire drop to detect the body in the horizontal position;

d. Measure the relative vertical elevation of the two rolling circles to check the position of the machine body in the vertical plane;

e. Use the method of moving the electric torque wheel to adjust the measurement of the two articles c and d, so that the machine body is in the correct position;

2. No-load test run:

1). Uninterrupted no-load for 8 hours, the temperature of each bearing should rise smoothly, and the temperature of the bearing should not be higher than 50 degrees Celsius at the termination of the test run;

2). The noise of gears should be average and should not be high or low;

3). After the test run, the bearings shall be observed without serious wear and abrasion.

A.Starting the machine

1. The following preparations should be made before starting the film wrapping machine;

a. Check and adjust the powder feeding device and protection equipment;

b. All bearings and lubricating devices of friction surfaces should have appropriate quantity of grease;

2. It is forbidden to start the film wrapping machine without checking the film wrapping machine and auxiliary mechanical equipment;

3. The steps to start the film wrapping machine are as follows:

a. Start the motor of the film wrapping machine.

b. Start the feeding and discharging conveying equipment.

B. Stopping

1. The steps to stop the film wrapper are as follows:

A. Stop adding raw material to the wrapper;

B. Turn off the drive motor of the wrapping machine;

C. Stop the equipment for transporting granular materials;

1. Dry grease should be smeared at the gears before starting the machine;

2. Dry grease to be smeared on the surface of rolling belt once in 7 days;

3. Bearing housing to be hit or renewed with new dry grease every three months;

4. Add gear oil once before the reducer is used and replace it every four months thereafter;

Pinion gear is worn, install pinion gear upside down, if both sides are worn, new gear is needed.
The intermediate connection between the large gear and the cylinder is damaged, adjust the connection and make appropriate treatment if necessary.

Clamping roller belt to the side of a concave joint

Clamp the belt to the concave joints with pads or wedges, but beware of over-clamping, which can lead to accidents, but uneven tensioning can cause the machine to jump and vibrate.

Wheel wear Refurbish or replace the wheel according to the degree of wear
Block wheel wear Repair, move, or replace with new block wheel depending on degree of wear

Simple body vibration
