The mobile impact crusher has been widely popular in recent years due to its simple operation, convenient transfer, high cost-effectiveness, high output, good product particle size, and built-in environmental dust reduction treatment device, which meets the relevant requirements of the country for environmental protection. The most common application is in the initial processing of solid waste resources such as construction waste. In the past, tracked mobile impact crushers were usually combined with tracked mobile screening stations. Nowadays, some companies have developed new types of tracked mobile crushing and screening integrated machines. This integrated machine can not only be used for production, but also effectively reduce the user's purchase cost. It is also an alternative solution for the initial processing of solid waste resources such as construction waste.
No matter what kind of machine it is, it is inevitable to encounter various problems during use. So what should we do to improve the production capacity of counterattack and bring more economic benefits to you who are currently using counterattack?
If the material contains a large amount of moisture, it is easy for the material to adhere to the crushing chamber and block during the feeding process, reducing the production capacity of counterattack crushing. Therefore, for materials with high moisture content, early drying or air drying can be adopted to reasonably reduce the humidity of the materials and improve the production capacity of counterattack.
If the material before crushing contains a lot of fine powder, it will reduce the impact crushing capacity. Because these fine powders can easily adhere, affecting transportation and unloading. If the counterattack breaker is equipped with a pre screened material belt, it can screen and process powdered materials, making the materials entering the crushing chamber more in line with the design requirements of counterattack breaker, effectively improving the production capacity of counterattack breaker.
Within the range of rated motor power, the higher the power of the main motor, the higher the production efficiency and capacity of the counterattack. So, in production, it is possible to increase the power of the main motor within the allowable range to enhance the production capacity of counterattacks.
The rotational speed of the rotor in the tracked mobile impact crusher is one of the important working parameters of the impact crusher, which plays a decisive role in the crusher's production capacity, product particle size, and crushing ratio. Experiments have shown that with the increase of rotor speed, the production capacity and crushing ratio of counterattack crushing significantly increase, and the product particle size will also be relatively finer. However, as the rotor speed increases, power consumption also increases, plate hammer wear accelerates, and production costs increase to a certain extent. Therefore, in production, we cannot blindly pursue the high speed of the rotor, and the speed increase should be appropriate.
At present, there are two types of counterattack boards in the market: line shaped counterattack boards and circular arc-shaped counterattack boards. The angle of each level of counterattack plate has a significant impact on the effective crushing force generated by the impact of materials on the counterattack plate, as well as on the impact and shear crushing effects of materials.
The structure of the zigzag counterattack plate is simple, but it cannot guarantee effective impact crushing of the crushed material. Therefore, when purchasing and debugging the counterattack plate, it is necessary to pay attention to the angle of the counterattack plate, and try to make the material perpendicular to the counterattack plate when colliding with it, in order to improve the production capacity of counterattack.
The commonly used arc-shaped counterattack plate has a gradually opening shape. The characteristic of this structural form is that at each point of the counterattack plate, the crushed material is impacted in a vertical direction, resulting in higher crushing efficiency and production capacity.
The counterattack material should be evenly distributed to prevent large chunks of material and non crushed materials from entering the crushing chamber beyond the specified limit. If abnormal vibration and noise are found in the counterattack, the vehicle should be stopped for inspection, the cause should be identified and the fault eliminated before restarting the counterattack.
The gap size between the counterattack plate and the plate hammer has a significant impact on the particle size of the product. Before starting up, the gap between the counterattack plate and the plate hammer should be adjusted to the specified range.
For worn wear-resistant parts, especially those that come into direct contact with materials such as plate hammers and impact plates, they should be replaced in a timely manner. When replacing the plate hammer, attention should be paid to weighing and selecting the new plate hammer to maintain good static balance of the rotor.
As the saying goes, 'Raise troops for a thousand days, use them for a moment.' In order to increase the production capacity of counterattacks and make more money, daily inspections, maintenance, and upkeep of counterattacks are also essential.
The machine runs smoothly. When the vibration suddenly increases, the machine should be stopped immediately to identify the cause and eliminate it;
Under normal circumstances, the temperature rise of the bearing should not exceed 35 ℃, and the high temperature should not exceed 70 ℃. If it exceeds 70 ℃, the vehicle should be stopped immediately to identify the cause and eliminate it;
When the wear of the plate hammer reaches the limit mark, it should be turned around for use or replaced in a timely manner;
After assembling or replacing the plate hammer, the rotor balance must be maintained;
When the rack lining plate wears out, it should be replaced in a timely manner to avoid damaging the casing.
Strictly inspect whether there is any looseness in the fixed components such as the anchor bolts, body bolts, bearing seats, and bolts at the guard plate of the fixed motor.
Check if the fixing parts of the counterattack plate are loose or broken.
Inspect the interior of the equipment, such as whether the wear of the plate hammer is severe, as the plate hammer has a significant impact on the particle size of the discharge. Also, check the condition of other vulnerable parts, including the degree of wear and the presence of crack defects.
Confirm the previous and next processes, and only start after the belt conveyor and bag filter are running normally.
