Technical answer: how to configure pebble machine-made sand production line?


The pebble is named for its shape like a pebble. It is taken from the sandstone mountain produced by the uplift of the ancient river bed after the crustal movement tens of thousands of years ago. It has experienced the impact of mountain torrents and the continuous extrusion and friction in the process of water transportation. Hard quality, good compression resistance, wear resistance and corrosion resistance, is a kind of pure natural stone. Due to the shortage of river sand, cobbles are often processed into machine-made sand by crushers and sand making machines, which are used in building houses and road construction projects.
 
So, what kind of equipment does a complete cobble machine-made sand production line need? How should it be configured?
 
Main equipment of pebble manufactured sand production line:
 
Jaw crusher (first break), cone crusher (second break) and sand making machine (third crushing) are generally divided into three sections.
 
Auxiliary equipment of pebble manufactured sand production line:
 
Vibrating feeder, vibrating screen, belt conveyor, sand washing machine.
 
This is the complete configuration of a cobble machine-made sand production line. Generally speaking, the auxiliary equipment such as feeding, screening, conveying and sand washing are indispensable. The crushing equipment of the main unit can be deleted according to the actual production situation. If the size of pebble raw material is not large, it can be directly sent to cone crusher to crush into stone size; if the raw material is stone size, it can be directly sent to sand making machine for machine-made sand production. This depends on the actual production of raw material size, output and other factors, need to be analyzed in detail.

Operation process of pebble manufactured sand production line:
 

1. The vibrating feeder evenly sends the pebbles into the jaw crusher for a section of crushing, and the broken stones from the jaw are about 100 mm-300 mm;
 
2. The belt conveyor sends the first broken stone into the cone crusher for secondary crushing. After screening by the vibrating screen, the stones less than 50 mm are sent to the sand making machine, and those larger than 50 mm are sent back to the cone crusher for further crushing;
 
3. After three-stage crushing - further fine crushing by the sand making machine, the materials meeting the requirements of the finished sand are directly sent to the finished material pile, and those that do not meet the requirements are sent back to the sand making machine for further processing until they are qualified.
 
Note: when the size of pebble is between 50mm and 300mm, it is directly broken by cone instead of the first section; when the material is less than 50mm, it is directly sent to the sand making machine for crushing without the first and second section crushing.

Crawler mobile crusher

Crawler crusher has higher flexibility than fixed crusher. Crawler crusher is directly driven by engine, which has higher efficiency and energy saving.
