Durable Jaw Crusher for High-Purity Silica Sand

Product Description

Jaw crushing Maching

Product Introduction:

A jaw crusher is a primary crushing equipment widely used in mining, construction, and aggregate processing to reduce large, hard materials (e.g., granite, limestone, gold ore) into smaller particles. This machine typically adopts a crank double-link mechanism, which minimizes stress on key transmission parts (eccentric shaft, connecting rod) despite high crushing reaction forces—making it suitable for large/medium-sized models handling tough materials. 

Product Structure:
The working parts of a jaw crusher are two jaw plates: one is the fixed jaw plate (fixed jaw), which is vertically (or slightly inclined outward at the upper end) fixed on the front wall of the machine body; the other is the movable jaw plate (movable jaw), which is inclined and forms a crushing chamber (working chamber) that is large at the top and small at the bottom with the fixed jaw plate. The movable jaw plate makes periodic reciprocating movements towards the fixed jaw plate, separating and approaching alternately.

Working Principle:

Main Features

When the jaw crusher works, the movable jaw plate makes periodic reciprocating movements towards the fixed jaw plate, approaching and leaving alternately. When approaching, materials are crushed by extrusion, splitting and impact between the two jaw plates; when leaving, the crushed materials are discharged from the discharge opening by gravity.
In the process of crushing huge stones into small stones, the first crusher is usually the "primary" crusher. The oldest and most robust crusher is the jaw crusher. When feeding the jaw crusher, materials are poured into the crushing chamber with jaw teeth from the top inlet, and the jaw teeth push the materials against the chamber wall with great force to crush them into smaller stones. 

1.Low noise and less dust.
2.Large crushing ratio and uniform product particle size.
3.Simple structure, reliable operation and low operating cost.
4.Safe and reliable lubrication system, convenient replacement of parts, and simple equipment maintenance.
5.Deep crushing chamber without dead zones, improving feeding capacity and output.
6.Equipment energy saving: 15%—30% energy saving for a single machine, and more than double energy saving for the system.
Wide adjustment range of discharge opening, meeting the requirements of different users.

FAQ

Q: How big is your factory?
How long have your company been providing complete quartz sand production line construction service?
A: Started in year 2012 with just one factory producing crushing machines, we have expanded into 4 work shops,31,300 m2, office 3200 m2,110 workers.
    Our rapid development was right after we extended our business into whole quartz sand production line construction in year 2017.
 
Q: What Information is needed to conduct the production line construction evaluation? 
A:1). Please provide your plant information, site, size, facilities and workshop size. 
   2). Please advise what is your raw ore parameters (size, element content) and your target parameters for the processed sand (purity, trace element content)?
   3). What is your handling capacity(tons per hour) ?
 
Q: Can we send the mineral samples to your company for you to conduct the mineral processing tests?
A: Yes, we have in-house lab and professional team to perform the test, and we can provide professional processing approach based on the test result.
