5 Tips To Make More Money With Your Jaw Crusher

2022-02-10 17:37:41

Jaw crushers are widely used in the crushing of various ores and bulk materials in mining and smelting, building materials, highways, railways, water conservancy and chemical industries. Jaw crushers are generally used as coarse crushing equipment in ore production lines, and their production capacity has an important impact on the production efficiency of the entire production line.

Feeding is the first step of a crushing production line, and then it is often broken with jaw crusher, which has an important impact on the production capacity of jaw crusher. In order to improve the productivity of jaw crusher, we must first use the feeder correctly. This article shares several feeding techniques to improve the production capacity of jaw crusher and help you create more profits.

1. The feeding size shall be strictly controlled to avoid jamming and blockage

There is such a formula for the design size of the feed port of the jaw crusher: the size of the feed port = (1.1 ~ 1.25) * the maximum particle size of the raw material.

Many production personnel do not understand it, and always take the measured inlet size as the maximum feeding size. Therefore, if the raw material exceeds the specified large particle size, it is easy to block the cavity and groove. Although it is not blocked repeatedly, each time it is blocked, the equipment will not operate normally for a long time. Therefore, strictly controlling the particle size of raw materials is one of the most important preconditions to ensure the normal operation of jaw crusher.

2.Strictly control the feeding amount to prevent blocking due to excessive

Many enterprises have carried out technical transformation on the silo because the initial feeding is insufficient, which seriously affects the production. However, due to the lack of devices to limit the feeding amount, there is often another phenomenon of overcorrection, that is, excessive feeding.

Because the working principle of jaw crusher is half rhythm, if excessive materials are input, it will cause the materials to be broken too late, and the broken materials can not be eliminated in time, resulting in material jamming. Therefore, both cutting and over feeding will affect the production capacity of jaw fracture.

3. Rhythm feeding and control feeding to ensure normal operation of jaw crusher

At present, the crushing section of beneficiation enterprises mostly adopts end chute for feeding, and 2 / 3 of the whole feeding equipment is even exposed outside the warehouse. Due to the remote feeding port, the feeding equipment has completely become a vibrating chute, which not only has poor feeding speed, but also has serious wear and tear. 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 vibration capacity or affecting the conveying effect under pressure.

Especially when the dump truck is used for direct unloading, the disadvantages of vertical feeding are more serious. Therefore, the technical guarantee for normal feeding is how to adjust the angle of the blanking bin to ensure that the blanking is smooth and does not press the material, and the rhythm of the miner is consistent with the processing rhythm of the jaw crusher.

4. Adjust the angle of the feeder and make full use of the screening function of the feeder to realize pre screening

Vibrating feeders often have grate bars with some screening functions. However, in practical application, due to amplitude, feeding angle and other reasons, the equipment is easy to block the grate bar in screening, which makes it lose its original efficiency. In the face of this situation, many enterprises block the grate with steel plate and turn it into a plate feeder.

In fact, when properly adjusted, the efficiency of the grate of the vibrating feeder is extremely obvious. Adjusting the amplitude and the angle of the feeder to fully release the screening function of the feeder is the best way to improve the total throughput.

5. Reasonably adjust the discharge port and bite angle to maximize the processing capacity of the equipment

The size of the discharge port of the jaw crusher determines the processing capacity of the equipment. Jaw crusher is often used as coarse crushing equipment, and the size of its discharge port should be based on the best feeding particle size of secondary crushing, and the size of discharge port cannot be increased or reduced arbitrarily.

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

In addition, the horizontal stroke of the moving jaw, the meshing angle of the discharge layer, the rotating speed, the material humidity, etc. are also the factors affecting the capacity of the jaw crusher. You can adjust these factors to improve the capacity of jaw crusher.
