Product introduction

      Scraper conveyor is a kind of conveyor, it uses scraper chain traction, so that materials in the trough uniform speed and uniform transportation, from the shape, its middle groove can be semi closed or fully closed, it has the head, middle part and tail part of three parts, widely used in coal mine, chemical mine, metal mine and power plant and other industries, is currently used for transportation in the market An important means of transportation for delivering materials.

 Scraper conveyor manufacturer
 
Product use
 
Scraper conveyor is mainly used in thin coal seam or extremely thin coal seam, medium thick or thick coal seam and gently inclined coal seam blasting mining, general mining, high-grade general mining, fully mechanized fully mechanized caving and other working faces to transport coal. It can also be used for driving roadway transportation and chute transportation. When supporting shearer, the middle groove of scraper conveyor is also the walking track of shearer.

Product features

1. Because the scraper conveyor adopts scraper chain traction, it needs more steel in design and production, so it has higher cost.
2. The whole body of scraper conveyor is low, but it is very strong and durable in structure. It can withstand the impact, impact, impact, pressure and other external forces of coal, ore or other materials, and its installation is relatively simple.
3. If there is no casing protection at the tail of the scraper conveyor, the scraper can be inserted into the material pile, and the scraper can take and transport by itself.
4. Scraper conveyor for the work of the bottom panel requirements are not high, can adapt to uneven or curved panel, in the transport of materials can be horizontal or inclined.
5. Because the running track of the shearer is similar to that of the scraper conveyor, the scraper conveyor can also be used as the running track of the shearer.
6. The scraper conveyor can feed or discharge at will in the conveying length, but it can't transport materials for a long distance.
7. The only disadvantage of scraper conveyor is that it is easy to cause chain dropping and chain jumping accidents when conveying materials.
 
 Scraper conveyor for mining

working principle

      The working principle of scraper conveyor is to fix a certain number of scraper firmly on the chain to form scraper chain, which makes it become the traction part of conveying machinery. The chute for conveying materials is open type, and it should be used as the bearing part of conveying machinery. In this way, when the machine starts to start, the rotating part of the head drives the sprocket on it to rotate, and the scraper chain bypasses the chain wheel for stepless operation Closed cycle operation, so that the scraper chain belt animal material of the traction part moves forward along the chute of the bearing part until the material is unloaded at the machine head.

Environmental conditions for use


1. The ambient temperature is between - 10 ° C and + 40 ° C.
2. In the environment without broken insulation gas or steam.
3. Environment with explosive gases such as methane and air mixture, coal dust, etc.
4. The altitude is below 2000m.
5. There is no long-term continuous dripping place.

Operation and maintenance

1. Before installing the machine, carefully check whether all parts are complete and install in strict accordance with the product manual.
2. Before operation, carefully check whether the intermediate groove is clean and whether there are iron blocks or hard objects entering the tank, so as to avoid foreign matters damaging the machinery.
3. Regular maintenance of the chain, roller and sprocket, to avoid excessive wear and tear, in order to reduce greater losses.
4. When the machinery is running and conveying, if there is abnormal noise, stop the machine immediately to eliminate the fault.
5. If the chain is broken or the tension is adjusted, check whether the chain is broken or repaired regularly.
6. Regularly check the fastening length of all bolts of the machine, and tighten them in time if they are loose;
7. Scraper is an important part of scraper conveyor. It should be checked regularly to see whether it is worn, damaged or bent. If there is, it should be replaced or repaired in time.
