Complete Limestone sand making plant | Process & machine list

Limestone sand making plant is a production facility used to process limestone into sand for various construction and industrial applications. Now let’s study the limestone crushing plant process . A complete limestone sand making plant typically consists of the following components:

Basic information

-Material: limestone mixed with clay
-Feeding capacity: 120 tons per hour
-Product: crushed sand
-Crushing stage: primary crushing, secondary crushing, tertiary crushing

Sand making plant process in detail

1. Raw materials loading

Raw materials site about 1 KM to crushing working site. Raw materials are loaded to the dump truck by excavator, and move to the loading place. Dump truck discharge all materials to the hopper.

2. Grizzly feeder separation

Under the hopper there is a grizzly feeder, grizzly bar distance 100mm, larger than 100mm are sent to the primary jaw crusher for crushing, while under 100mm will be sent to join the materials discharge from primary jaw crusher.

3. Primary crushing

Primary jaw crusher PE600X900, with C.S.S. (closed side setting) size 120 mm, crushing capacity up to 120 tons per hour.
Motor 75KW main shaft rotation speed 250 rpm. Discharge materials together with the under grizzly materials will be sent to secondary crushing.

4. Secondary crushing

Secondary crusher by two sets of jaw crushers PEX 250x1200 inches, which is specially for secondary crushing use, maximum feed size 8 inches, C.S.S. size 40mm, main shaft rotation speed 330 rpm, motor 37KW per set.

Two sets capacity reaches 120 tons per hour. Crushed materials will be sent to horizontal shaft impactor or HSI for sand making.

5. Tertiary crushing

Tertiary crushing is by two sets of vertical shaft impactor(HSI), it is designed and produced by Baichy Machinery, with hydraulic opening device, easy for maintenance.

VSI with linear speed 50 meters per second, one set motor 160KW, very powerful and ideal equipment for limestone to produce sand.

Above the two VSI sand making machine is a hopper, and under the hopper there are two small vibrating feeders, it makes sure continuously and evenly feeding, so materials will be fed along the rotors, thus guarantees evenly wearing.

More than 70% crushed materials are less than 5mm, and 90% less than 10mm, 100% less than 16mm. Per set capacity up to 70 tons per hour, two sets guarantee capacity 120 tons per hour. Crushed materials are sent to vibrating screen for separation.

6. Screening and sand washing

Materials from two sets of vertical shaft impactor are sent to a double layer vibrating screen, mesh size 10mm and 5mm.

Sand of 0-5mm are sent to a screw sand washer for washing, 5 to 10mm and above 10mm are sent to stockpile as end products.

Equipment are connected by belt conveyors.
