Introduction of Cobblestone Crusher

The main component of pebbles is silica, and the colors that are often presented are black, red, white, yellow, blue-gray, etc., which is a very ideal natural building material. Therefore, the reserves of pebbles are also very large, mainly distributed in Shandong , Jiangsu, Liaoning, Chongqing, Guangxi, Guizhou and other places, have high utilization value.

Cobblestone processing generally needs to go through two stages of crushing and sand making, and crushing requires the use of a cobblestone crusher. Because there are so many cobblestone crushing equipment on the market now, many users do not know how to choose. A common cobblestone crusher.

Several crushers commonly used for pebbles

There are actually many types of cobblestone crushers. Among them, there are cobblestone jaw crusher, cobblestone counterattack crusher, cobblestone hammer crusher, etc. The following is a brief introduction to these equipment.

1. Pebble jaw crusher machine

The cobblestone jaw crusher is currently on the market with a better effect on cobblestone crushing. The cutting-edge feature of this equipment is that it can crush large pieces of pebbles, without the need for pre-crushing processing work, reducing costs, in addition to the following advantages

a, The crushing efficiency is high, the crushing ratio is large, the amount of pebbles processed per unit time is very large, and the equipment runs very smoothly during the processing;

b. The finished pebbles have uniform particle size after crushing, and the content of particles is also very large, which reduces the needle-like pebbles and meets the material requirements of the enterprise;

c. The crushing cavity is deep and there is no dead zone, and the amount of pebbles processed per unit time is also very large, which improves the output of the equipment and the overall profit of the processing plant;

d. The price is affordable, which reduces the investment cost of the majority of users, and the environmental protection measures in the work process are also done very well, which truly protects the environment.

2. Pebble impact crusher machine

Cobblestone impact crusher machine is mainly used as an intermediate crushing equipment for pebbles. This equipment is very specific to the crushing of pebbles, so that the finished pebbles after crushing are small. The characteristics of several such equipment are introduced below.

a. The granularity of the finished pebbles obtained by crushing can be well controlled, so that it can meet the construction requirements of most users;

b. The energy consumption is very low, the entire work process is reduced, and the energy consumption of the equipment is reduced by more than 50%, which saves a lot of operating costs for users;

c. Professional maintenance tools make it more convenient to repair the equipment in the event of a failure, and change the downtime of the equipment during maintenance;

d. The operation can be performed 24 hours a day, and there will be no quality problems during the operation, and the equipment can always operate stably.

3. Hammer broken pebbles

Cobblestone hammer crushing is mainly used for the middle and fine crushing operations of pebbles. The converted pebbles meet the requirements of the feed inlet of the subsequent material receiving equipment and have performance advantages. See details for details.

a. The hammer head is made of high-grade wear-resistant materials, resulting in super crushing ability, and the degree of wear in the working process is also very small;

b. The probability of failure during work is also very low, even if there are occasional repairs, it is more convenient and quick to repair;

c. It can withstand the crushing operation of pebbles, the crushing efficiency is very high, and the output of the equipment is effectively improved.

Analysis of the crash phenomenon of the jaw crusher during operation

“When the jaw crusher was working, I didn’t know why it (jaw crusher) stopped there, and then I had to hurry up to prevent the motor from burning out.” The person who said this was from the concentrator. A jaw crusher operator said that if you can’t grasp its temper, it will often cause the jaw crusher to crash. Therefore, when crushing materials, you must pay attention to the uniformity of the cutting , And the hardness of the material is based on the hardness of the local material. If it is hard, an additional process can be added.

What are the main factors that affect the work of the jaw crusher? Under normal circumstances, the main factors that affect the work of the jaw crusher are the engagement angle and the number of revolutions.

The angle of engagement is the angle between the movable jaw and the fixed jaw. According to the calculation, the maximum engagement angle can reach 32 degrees. In actual use, it is less than 25 degrees, generally around 18-20 degrees. If the biting angle is too large, the ore in the crushing cavity will be squeezed upwards, causing injury or damage to other equipment. At the same time, the productivity will decrease as the biting angle increases (the crushing ratio increases). Adjusting the size of the discharge port also changes the size of the angle of engagement. In actual life, the size of the discharge port is adjusted according to the requirements of the discharge particle size. Therefore, it is reasonable to enlarge the discharge port as much as possible under the requirement of ensuring the product size. The size of the discharge port can be adjusted by adjusting the block. When adjusting the size of the discharge port, pay attention to the relationship between the crushing ratio and the productivity.

Within a certain range, increasing the number of revolutions of the eccentric shaft can increase the production capacity of the jaw crusher, but it will also increase the power consumption per unit weight of ore. If the rotation speed is too large, the crushed ore in the crushing cavity will not be discharged in time, and blockage will occur, which will reduce the production capacity and increase the power consumption. Therefore, the jaw crusher should have a more suitable number of rotations.

The eccentric shaft, connecting rod, movable jaw plate, shaft and liner of the jaw crusher are the main wearing parts, which require frequent attention to lubrication and replacement.

After reading the above explanation of the common failures of the jaw crusher, we can clearly know that in the future, when the jaw crusher has problems, we can follow these problems to do the troubleshooting and find the cause of the failure.
