The front and rear ends of the mill barrel leak slurry Cause: The bolt is loose and leaking, replace the rubber pad, and tighten the bolt. If the bolt is loose in a large area and the bolt cannot be tightened, the lining plate is seriously worn, and the flat head of the bolt is also seriously worn. The lining plate needs to be replaced and the bolt is replaced. The vibration of the mill transmission part is large, and the current fluctuation is large. Reasons: 1. Pinion bearing wear 2. Large and small gear meshing is not good 3. Coupling is different 4. The gear and bearing of the reducer are seriously worn, and the side guard plates, torque rods and brake pads of the clutch are seriously worn. Solution: Replace the worn parts, adjust the gear meshing clearance in strict accordance with the technical requirements, and adjust the concentricity. The mill suddenly trips during normal operation Reasons: (1) insufficient air pressure (2) insufficient oil pressure (3) high oil temperature an examination: (1) Check whether the air compressor works normally, whether there is leakage in the pipeline, whether the pressure regulator is faulty, etc. (2) Check if the oil level of the fuel tank is suitable, whether the oil pump works normally, what is the difference between the oil supply pressure and the outlet pressure of the pump, and whether the pipeline is blocked or not; (3) The tour detector shows that the oil temperature is high, and the actual temperature is felt by hand. If the actual temperature is not much different from the display temperature, the cause must be found before starting. 4. Grinding rough (1) The grinding concentration is too small, the grinding time is not enough, the slurry flow rate is too fast, so it runs rough. Treatment method: reduce the amount of ore water, and increase the amount of ore to be properly added; (2) The concentration of grinding is too large, the concentration of pulp is too large, the buoyancy of the slurry increases, and the grinding and stripping action of the small steel ball is reduced, so it runs rough. Treatment method: reduce the amount of ore added or increase the ore water; (3) The ball filling amount or steel ball ratio is not suitable, check the ball filling amount and the steel ball ratio.
The Conveying Equipment Series is a collection of machines designed to transport materials from one place to another. These machines are used in a variety of industries, including manufacturing, mining, agriculture, and construction. They are essential for moving materials efficiently and quickly, reducing labor costs, and improving productivity.
One of the most common types of conveying equipment is the conveyor belt. This machine consists of a belt that moves continuously, carrying materials from one end to the other. Conveyor belts are used to transport a wide range of materials, including grains, coal, rocks, and chemicals. They are available in different sizes and configurations, depending on the specific needs of the industry.
Another type of conveying equipment is the bucket elevator. This machine consists of a series of buckets attached to a chain or belt. The buckets are used to scoop up materials from one level and transport them to another level. Bucket elevators are commonly used in the agricultural industry to transport grain and other crops.
Screw conveyors are another type of conveying equipment. These machines consist of a rotating screw that moves materials along a trough or tube. Screw conveyors are used to transport bulk materials such as grain, cement, and chemicals. They are commonly used in the food processing industry for transporting ingredients and finished products.
Pneumatic conveying systems are also commonly used in many industries. These systems use air pressure to move materials through pipes or tubes. Pneumatic conveying systems are often used in the chemical industry to transport powders and other materials that are difficult to handle with other types of conveying equipment.
In addition to these types of conveying equipment, there are many other machines available for transporting materials. Some of these include belt conveyors, roller conveyors, vibrating conveyors, and chain conveyors. Each of these machines has its own advantages and disadvantages, depending on the specific needs of the industry.
Overall, the Conveying Equipment Series is an essential collection of machines for many industries. These machines are designed to move materials efficiently and quickly, reducing labor costs and improving productivity. With so many different types of conveying equipment available, it is important for industries to choose the right machine for their specific needs.
