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.

Concrete crushing based on the high-voltage pulse ...

When the hole diameter is 30 mm, the maximum hole spacing can be 300 mm; when the hole diameter is 50 mm, the maximum hole spacing can be 400 mm; when the hole diameter is 70 mm, the maximum hole spacing can be 500 mm. Considering the commonly used pore diameter, reasonable crushing size and working efficiency of concrete, it is suggested to take the pore diameter of 50 mm and the hole

Concrete crushing based on the high-voltage pulse ...

With the increase of the hole diameter and the decrease of the hole spacing, the crushing effect of the concrete is improved. 2) For general section size beams of which the width is not greater than 500 mm, it is recommended to use a single row of holes, taking hole diameter of 50 mm, hole spacing of 400 mm and hole end (edge) distance of 400 mm as the preferred
