Five Ways to Maximize Jaw Roll Crusher Output

Jaw roll crusher has a shorter name—E Po in Chinese. It consists of two jaw plates, moving jaw and stationary jaw, which form a crushing cavity to simulate the movement of the two jaws of animals and complete the crushing operation of materials. It is widely used in a variety of ores and large pieces of material crushing in mining smelting, building materials, highways, railways, water conservancy and chemical industries. How to improve the working efficiency of jaw roll crusher from the source? This problem has attracted the attention of many professionals. Today, the author has compiled some suggestions, hoping to help you realize the maximum capacity of jaw roll crusher. When it comes to improving jaw crusher capacity to maximize, of course, we have to start with feeding. Feeding is the first step of jaw crusher, which has an extremely important effect on productivity. If there is a mistake at this source, the subsequent crushing process will not be smooth.

1. Strictly control the feeding amount to prevent clogging phenomenon caused by excessive materials
Many enterprises have carried out technical renovation of silos due to insufficient initial feeding which has seriously affected production. However, due to the lack of devices to limit the feeding amount, the renovated silos often suffer from another phenomenon of overcorrection, i.e. excessive feeding.

As the working principle of jaw crusher is half-rhythm work, if too much material is put in, it will cause the material to be too late to be crushed, and the crushed material cannot be discharged in time, resulting in material jamming. Therefore, the capacity of jaw crusher will be affected by material cut-off and excessive feeding.

2. Strictly control the feeding size, avoid cavity blocking
There is such a formula for the design size of the jaw crusher feed opening: the feed port size = (1.1 ~ 1.25) * the maximum particle size of the raw material.

Many production personnel do not understand it and always take the measured feed opening size as the maximum feed size. Therefore, the raw materials with large particle size in excess of the regulations become the prime culprit for blocking the cavity groove. Although it is not blocked repeatedly, the equipment cannot operate normally for a long time every time it is blocked. Therefore, strictly controlling the particle size of raw materials is one of the most important preconditions to ensure the normal operation of best jaw crusher.

3. Reasonably adjust the discharge opening and bite angle of the jaw crusher to increase the processing capacity of the equipment to the maximum extent.
The size of the discharge opening of the jaw crusher determines the processing capacity of the equipment. However, jaw crusher is often used as coarse crushing equipment, and the size of its discharge opening should be based on the optimal feeding particle size of secondary crushing, and the size of the discharge opening cannot be arbitrarily increased or decreased.

The adjustment of bite angle (the included angle between movable jaw and fixed jaw) needs to be strictly carried out, generally within the range of 17 ~ 26 degrees (the actual situation shall prevail).

To sum up, feeding is the first step in crushing production. Attention should be paid to the above points and equipment feeding should be done well to lay the foundation for high-yield operation of a best jaw crusher.

4. Control feeding and stick to a rhythm to ensure the normal operation of Hubei break
At present, the crushing section of beneficiation enterprises mostly uses end chute for feeding, and 2 / 3 of the whole ore feeder is even exposed out of the bin. Due to the remote feeding opening, the ore feeder is completely turned into a vibrating chute, which not only leads to poor feeding speed, but also causes serious wear. The best feeding position of the feeder should be within 1/3 of the top of the equipment, but vertical feeding is strictly prohibited to prevent the equipment from losing its vibration ability or affecting the conveying effect under pressure.

Especially if dump truck is used for direct unloading, the disadvantages of vertical feeding will be more serious. Therefore, how to adjust the angle of the blanking bin to ensure smooth blanking and no material pressing, so that the rhythm of the ore feeder matches the processing rhythm of the jaw crusher machine, is the technical guarantee for normal feeding.

5. Adjust the angle of the ore feeder and make full use of the screening function of the ore feeder to realize functions of screening and pre - screening
Vibrating feeders are often equipped with grate bars containing some screening functions. However, in actual application, due to amplitude, feeding angle and other reasons, the device is prone to block grate bars during screening, which makes it lose its original efficiency. Faced with this situation, many enterprises blocked the grate bar with steel plates and turned it into a plate feeder.

In fact, the efficiency of the grate bar of the vibrating feeder is extremely obvious under the condition of proper adjustment. Adjusting the amplitude and angle of the feeder and fully releasing the screening function of the feeder are the best ways to increase the total throughput.
