Introduction to the processing technology system of the jaw crusher production line

Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence , Increase its market value. Common production lines are: stone production line and sand production line.

Sand production line

Sand production line processing technologye

On the basis of the stone production line, sand making machine equipment for fine crushing and shaping is added, which can realize the simultaneous production of machine-made sand and crushed stone. The entire production line is flexible in construction and diverse in output, which can meet the various processing requirements of customers. , To achieve the purpose of "one line with multiple uses", it is an ideal production line choice for producing highway surface materials, high-speed railway sand and gravel aggregates, hydropower station sand and gravel materials, port terminals and airport runways.

Pneumatic Conveying - Jenike Johanson

Pneumatic conveying is the process of transporting bulk materials in a gas stream (typically air or nitrogen) through a pipeline. Though this conveyor has several benefits over using screw and belt conveyors, a pneumatic conveying system can experience:

Numerical simulation of pneumatic conveying ...

Pneumatic conveying refers to a conveying method of conveying particles or powders in a pipe by a gas (air or other gases) with pressure and initial velocity [1]. In addition to being used on large industrial assembly line equipment, this technology is increasingly being used in equipment dust removal systems to remove impurities from the system.

10 Considerations for Pneumatic Conveying System

2015-11-17  Conveyor manufacturers must know whether the system requires sanitary design, using 316L stainless steel, or if 304 stainless steel or carbon steel will suffice. In pneumatic conveying systems, all equipment must complement each other. If one piece of equipment is too large or too small, it will keep the system from working properly.

2004-9-23  The phenomenon of electrostatic charge generation and its effects on granular flow behavior in a pneumatic conveying system was studied. The main parameters used for quantitative characterization of the phenomenon were the induced current, particle charge density, and equivalent current of the charged granular flow. These were measured using a digital electrometer, Faraday
