The jaw crusher is an important equipment in the 2,000-ton gravel production line. The output of the jaw crusher directly affects the operating efficiency of the entire production line. The following introduces methods to improve the production capacity of the jaw crusher:

1. Strictly control the feed size to prevent cavity jamming and blockage

The design size of the feed port of the jaw crusher has such a formula: feed port size = (1.1~1.25) * the size of the raw material's very large particles.

Production personnel often misunderstand and regard the measured size of the feed port as the maximum feed limit, which causes large-size raw materials to easily jam the cavity and affect the operation of the jaw crusher. Each blockage causes the equipment to shut down for a long time, seriously affecting production. Therefore, it is very important to strictly limit the particle size of the raw materials. It is one of the prerequisites for ensuring the smooth operation of the crusher, and it is of great significance to reduce downtime and improve production efficiency.

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

The jaw crusher relies on semi-rhythm mode to operate. Excessive feeding will cause material accumulation without crushing. At the same time, the crushed material is difficult to be discharged in time due to blockage, resulting in material jamming. This situation not only hinders the crushing process, but also directly reduces the production efficiency of the crusher. Therefore, it is crucial to accurately control the material supply to avoid material interruption or excessive feeding to maintain the efficient production capacity of the jaw crusher.

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

At present, the crushing section of the mineral processing enterprise mostly uses end chute feeding. 2/3 of the entire 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 serious wear. The ideal feeding position of the feeder should be within the top 1/3 of the equipment, but vertical feeding is strictly prohibited to prevent the equipment from losing vibration ability under pressure or affecting the conveying effect.

Especially when the dump truck is used for direct unloading, the disadvantages of vertical feeding are more serious. Therefore, how to adjust the angle of the feeding bin to ensure smooth feeding without pressing the material, and make the rhythm of the feeder match the processing rhythm of the jaw crusher, is the technical guarantee for normal feeding.

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

Vibrating feeders often have grate bars and some screening functions. However, in actual applications, due to reasons such as amplitude and feeding angle, the equipment is very likely to have block material blocking the grate bars during screening, causing it to lose its original efficiency. Faced with this situation, many companies block the grate bars with steel plates to turn it into a plate feeder.
