The first step in the machine-made sand production process is feeding, followed by the rough crushing of stones by the Type 69 jaw crusher. Therefore, the correct feeding method is crucial to increasing the output of the Type 69 jaw crusher.
Here I would like to share with you several feeding techniques, hoping it will be helpful to increase the production capacity of Hubei.
Strictly control feed size
An important parameter of the Type 69 jaw crusher is the maximum feeding size.
The design size of the feed port of the 69-type jaw crusher has such a formula: feed port size = (1.1~1.25)*larger particle size of the raw material.
In actual use, the operator can easily use the measured feed inlet size as the largest feeding size. Once the large pieces of raw material exceed the specified size of the jaw crusher model, it will easily cause the cavity to become blocked. As long as a blockage occurs, the equipment will not function properly for a certain period of time.
Therefore, the size of raw materials needs to be strictly controlled to ensure the normal operation of the 69-type jaw crusher.
Strictly control the feeding amount
Due to insufficient initial feeding, many companies have seriously affected production, so they have carried out technical transformation of the silo. However, due to the lack of a device to limit the feeding amount, another phenomenon of overcorrection often occurs in the transformed silo, namely overfeeding. .
Since the working principle of the jaw crusher is semi-rhythm operation, if too much material is put in, the material will not be broken in time, and the broken material cannot be removed in time, resulting in material jamming. Therefore, both material shortage and overfeeding will affect the output of the jaw crusher.
Rhythm feeding, controlled feeding
Nowadays, most of the crushing sections of mineral processing enterprises use end chute for feeding. 2/3 or even the entire feeding equipment is exposed outside the warehouse. Due to the remote feeding port, the feeding equipment has completely turned into a vibrating chute. Not only Feeding speed is poor and wear is severe.
The optimal feeding position of the mining machine should be within the top 1/3 of the equipment, but vertical feeding is strictly prohibited to prevent the equipment from losing its vibration ability due to pressure or affecting the conveying effect.
Especially if a dump truck is used to unload materials directly, the disadvantages of vertical feeding are more serious. Therefore, how to adjust the angle of the unloading bin to ensure smooth unloading without pressure, and to ensure that the rhythm of the mining machine matches the processing rhythm of the 69-type jaw crusher is the technical guarantee for normal feeding.
