As a large-scale mechanical Used Portable Concrete Crusher equipment, the crusher's workload is large, and its working environment is harsh, which makes the crusher prone to failure during use. Therefore, equipment operators should pay attention to the maintenance and maintenance of equipment, understand the factors that affect the normal operation of equipment, ensure the normal operation of equipment, and prevent equipment failure from causing serious losses to enterprises. Our technical experts analyzed several main factors that affect the operation of the equipment for the majority of users:
First of all, in the Ultrafine Mill Sale Indonesia work, the temperature of each component has its own normal range, too high or too low will affect the normal operation of the device. During the operation of the crusher, one must prevent the crusher from being overloaded at low temperatures. Before the equipment is operated, the preheating work must be done first, and the material must be transported after the appropriate temperature has been reached. Second, to prevent the machine from running at high temperature, often check the value on the temperature table, when the temperature is too high, it should be stopped in time to check.
Secondly, dust, soil, metal debris and other debris can also affect the operation of the equipment. Once impurities enter the interior of the mechanical equipment, the harm is great. Not only will the relative movement be blocked, the wear of the parts will be accelerated, but also the mating surface will be scratched, the lubricant film will be damaged, and the temperature of the parts will increase and the lubricant will deteriorate. Preventing the entry of impurities is not only related to the quality of the equipment and the lubrication of the equipment, but also requires on-site operators to do protective work to reduce the entry of external impurities.
Later, the chemical substances contained in materials, air, rain, etc. are also an important factor in the corrosion of equipment. For the corrosion of materials, the materials can be processed in advance to reduce the impact. At the same time, operators must take effective measures to reduce chemical corrosion according to weather conditions.
The relatively low temperature in Used Portable Concrete Crusher winter will not only greatly reduce the service life of the crusher, but also make it easier to freeze the oil and water in the crusher, which will affect the normal operation of the crusher. Therefore, users in winter should thoroughly check and maintain the crusher to ensure that the crusher can safely pass through the winter. Specific attention should be paid to the following points: First, do the cleaning work of the crusher. Descale and decontaminate the various parts of the crusher, and do the preliminary work for the next maintenance. Second, pay attention to the selection and replacement of oil. At low temperatures, the viscosity of the oil will increase and the fluidity will deteriorate, which will affect the operation of the engine and the operation of the equipment. Therefore, the user should choose an oil suitable for winter use and replace it in time to ensure the normal operation of the equipment. Later, the maintenance of parts. In the low temperature state, the work of many components will be affected, so the user should do the maintenance work of the parts, especially the insulation work. Please choose the more powerful and cost-effective for the crusher.
The cylinder for realizing the hydraulic Vertical Roller Mill Production Process safety function is arranged in the connecting rod body. Before the crusher starts, start the hydraulic oil pump to fill the oil under the cylinder piston of the connecting rod body, so that the oil pressure does not exceed 200kg / cm2. Then start the main motor, the crusher works normally. When the crushing cavity enters the non-crushed object, the oil pressure of the lower cylinder of the connecting rod exceeds the specified pressure, forcing the high pressure relief valve to open, so that the oil flow of the lower cylinder releases the pressure of the upper cylinder, thus lowering the working connecting rod and thrust plate The movable jaw stops moving, and the main motor, eccentric shaft and the upper part of the connecting rod operate as usual, thus protecting the machine from damage. Stop and take out non-broken objects, and then start again.
3. Hydraulic adjustment device. Before adjusting, first loosen the nut and tie rod spring nut connecting the slider base and the rear frame, then start the oil pump, fill the oil cylinder with oil, make the piston move the slider base forward, and then Increase or decrease the gasket between the rear frame to adjust the size of the ore port, after the adjustment, unload the oil, tighten the nut between the slider base and the rear frame and readjust the nut of the drawbar spring. The adjustment is complete.
temperature. When the temperature drops, the lubricating oil will thicken; when the Maintenance Of Blade Of Vertical Mill temperature rises, it will become thinner. Therefore, under high temperature conditions, heavy lubricating oil is required to prevent dry friction between metal and metal; under low temperature conditions, equipment requires low viscosity lubricating oil.
Hit the load. When the engine of the equipment emits rhythmic power, the equipment needs thicker lubricating oil to prevent the boundary lubrication caused by the instantaneous cracking of the oil film, because in this case, very little lubricant can be left. In this case, a lubricant containing extreme pressure additives is needed. Gear type. When using straight teeth, helical teeth, herringbone teeth and bevel gear pairs, the roller crusher will produce an effective oil film when sliding and rotating to reduce the direct meshing contact between the two wheels. On the equal shaft transmission, the direction of relative sliding motion is not conducive to maintaining the oil film. On this transmission, boundary lubrication often occurs in large quantities.
Each factor will have an impact on the selection of gear lubricants. Therefore, users should understand the factors that affect the selection of lubricants before choosing lubricants, so as to comprehensively consider and choose the lubricants that are more beneficial to the operation of the equipment. Choose a more professional crusher equipment manufacturer.
1. The bearing of impact Maintenance Of Blade Of Vertical Mill is easy to generate heat. Bearing heat indicates lack of oil. At this time, it is necessary to refuel in time. Of course, too much will also cause bearing heat. Therefore, when refueling, be sure to check the oil level, bearing damage should be replaced in time. 2. Abnormal vibration of impact crusher. Abnormal vibration indicates that the material is too large and unevenly worn. At this time, check the feed size, replace the hammer head in time, adjust the rotor, and reinforce the bolts. 3. The belt of the impact crusher is easy to turn over. Turning the belt over indicates that the belt is badly worn and the triangle belt needs to be replaced.
4. The output granularity of the impact crusher is too large. The factors affecting the output particle size are generally: the hammer head is seriously worn, the gap between the hammer head and the impact plate is too large, or the feed particle size is too large, etc., which requires specific measures according to the specific situation.
Jaw crusher Zimbawe Stone Crushers has the advantages of simple structure, convenient management and repair, safe and reliable work, and wide application range. It is suitable for coarse and medium crushing of hard and medium hard materials, such as crushed limestone, clinker and gypsum.
The disadvantage is that the work is intermittent and there is an idle travel, which increases non-productive power consumption. Due to the reciprocating movement of the movable jaw and the connecting rod, a large inertial force is generated during work, which causes the parts to bear a large load and requires high quality of the foundation. When crushing sticky and wet materials, the production capacity drops, and even clogging occurs. When crushing dry flakes, the flakes easily pass along the width direction of the jaw plate and cannot achieve the purpose of crushing, causing the feed slide or the feed inlet of the next crusher to be blocked. The bang is not big.
Use in the sand production line: In the sand production line, the material usually needs to pass through multiple crushing processes to achieve the final effect. Among them, the jaw crusher is indispensable as the first crushing process. It is also very important.
