How to improve the production efficiency of jaw crusher and output more sand and gravel is the concern of many bosses. After all, how much sand and gravel is produced means how much wealth is produced.

If you want to gain wealth, improving the efficiency of jaw crushing is the key

As an expert in head crushing, the production efficiency of jaw crusher has an important relationship with factors such as material selection, production equipment, operation level, lubrication and maintenance.

1. Material selection

  • ①The hardness of the material. The hardness of the material is very important. The harder the material, the more difficult it is to break, and the wear and tear of the machine is particularly serious. For the same type of jaw crusher, the output of crushed granite and limestone will be different, and the output of the former is less than that of the latter.
  • ②The humidity of the material. If the moisture contained in the material is relatively large, the material will easily adhere to the crushing cavity when it is crushed, and it is also easy to cause blockage during the cutting process, resulting in a reduction in output and unpredictable results.
  • ③ The powder content of the material. Before crushing, the more fine powder the material contains, the more it will affect the crushing quality. Because these fine powders are easy to adhere to the crushing cavity or conveyor belt, affecting the conveying. Therefore, if the fine powder content is large, it should be sieved in advance.

 

2. Crushing equipment

Sharpening knives does not miss woodcutters. Excellent jaw crusher will have a multiplier effect on output. Different crushers have different applicable conditions. The crushers with excellent performance and high quality are used, which have large crushing ratio, high crushing efficiency and long service life.

The accessories of jaw crusher, such as jaw plate, hammer head, etc., should choose wearing parts with good wear resistance, which will make the equipment have large crushing capacity and long crushing time. If it is not wear-resistant, it will affect the crushing capacity of the jaw crusher.

3. Operation level

In order to prevent the irregular operation of technicians from affecting the normal performance of the crusher, attention should be paid to these aspects:

  • ①Strictly control the feeding size. There is a formula for the design size of the feeding port of the jaw crusher: the size of the feeding port = (1.1~1.25) * the maximum particle size of the raw material. Many people always use the measured feeding port size as the maximum feeding size, so that the largest particle size raw material becomes the culprit of blocking the cavity. Every time it was blocked, the equipment would not function properly for a long time. Therefore, strictly controlling the particle size of raw materials is an important condition to ensure the normal operation of the jaw crusher.
  • ②Strictly control the feeding amount. Many enterprises have seriously affected production due to insufficient feed. After the technical transformation of the silo, due to. The lack of a device to limit the amount of feed often results in overcorrection, that is, overfeeding. The larger the feed amount, the longer the crushing time of the jaw crusher, and the wear of the machine will increase, which will affect the production capacity of the jaw crusher. Therefore, strict control of the feeding amount and uniform feeding can ensure the stable production of the jaw crusher.
  • ③Reasonably adjust the jaw crusher discharge port and angle. The size of the discharge opening of the jaw crusher determines the processing capacity of the equipment. In fact, the size of the discharge opening of the jaw crusher should be based on the optimal feeding particle size of the second-stage crushing, and the size of the discharge opening cannot be arbitrarily increased or reduced. In addition, the adjustment of the bite angle (the angle between the movable jaw plate and the fixed jaw plate) is generally in the range of 17 to 26 degrees.

4. Lubrication and maintenance

The use of any equipment is inseparable from lubrication and maintenance. The connecting rod bearing, eccentric shaft bearing and elbow of thrust plate of jaw crusher are lubricated with lubricating oil. It is more suitable to use No. 70 mechanical oil in summer, and No. 40 mechanical oil can be used in winter. Note that before adding grease, the grease nipple and grease gun should be cleaned to prevent dust from entering the bearing housing.

For jaw crushing equipment, regular repair and maintenance are also required to discover and eliminate potential problems of the crusher in time to avoid failures, which can promote the improvement of crushing efficiency.

Riding the wind, born to be broken. With the start of major engineering projects in many places, only by taking the lead in improving the production efficiency of jaw crushing, sand and gravel enterprises can ensure a steady supply of sand and gravel, thereby obtaining ideal wealth. In the end, I hope that we will not be trapped in the season, work hard before the cold weather is full, and achieve our own perfection.
