project instruction:

Materials: The main stone is river pebbles, including some quartz stone, limestone, etc.; output is 400 tons/hour;

Main crushing equipment:

Two vibrating feeders WL1350

A European version jaw crusher PE750x1060

Two spring cone crushers HJC1650

Two vertical shaft impact crushers (sand making machines) GPR15000

Two vertical double-roller sand making machines DR1500

A fine sand recovery integrated machine TD2445x2

Six vibrating screens YA3080

Six sand washing machines XSD3620

Six dewatering screens TD2445

Brief description of crushing process:

First, the stone is evenly and continuously fed into the jaw crusher for preliminary crushing under the action of the vibrating feeder;

Then the coarsely crushed stone is sent to the spring cone crusher by a belt conveyor for re-crushing;

Secondly, the finely crushed stone is screened by a vibrating screen, and materials with different particle sizes are sent to the sand making machine for re-crushing to make sand; stones that do not meet the particle size requirements are returned by the belt conveyor and sent to the vertical shaft impact crusher again. Broken, forming a closed circuit for multiple cycles.

Finally, the materials output from the sand making machine are sent to the vibrating screen for separation. After separation, the materials are sent to the sand washing machine, dehydration screen, etc. to dry out the finished sand.

Outstanding advantages of river pebble sand making production line

1. The river pebble sand making production line is simple and convenient to operate, has a high degree of automation and high maintenance efficiency;

2. The equipment operation cost is low, it is a one-time investment, and the capital recovery is quick;

3. The finished product has good quality, uniform particle size, good particle shape and low powder extraction rate;

4. The front line is multi-purpose and can be flexibly adjusted to produce marketable products, greatly reducing project investment.
