What is the latest technological process of sand and gravel production line?

Sand and gravel production line is a technological process of mining large stones (pebbles, river pebbles, granite, marble, basalt, etc.). ) after coarse crushing, medium crushing, screening, sand making, sand washing and other treatments. Orderly, and finally made into high-quality sand aggregate needed for infrastructure construction. According to different material properties, finished product granularity, hourly output, working environment, investment cost, etc. , sand and gravel production process configuration equipment is different.

1. Crushing: large rocks are evenly sent to the fine jaw crusher by the vibrating feeder for preliminary coarse crushing and fine crushing;

2. Screening: raw materials processed by fine jaw crusher need to be screened by vibrating screen for multiple layers;

3. Sand making: the screened stone is sent to a sand making machine for efficient fine grinding and sand making to obtain the finished machine-made sand.

4. Sand washing: If you need to wash the sand, you can add a sand washer to wash it and dry it.

Sand and gravel production site

Give an example to illustrate the configuration scheme of ordinary gravel production line with an annual output of 30 tons:

Configuration equipment: raw material bin, B500 * 18m conveyor, HVSI7611sand maker, B500 * 19m conveyor, B500 * 20m conveyor, B500 * 10m conveyor, and

Features: simple production line configuration, convenient transportation and installation, and low investment cost. It is suitable for small pebbles sand production and is an ideal choice for small sand production plants. Among them, the equipment HXVS sand making machine has the characteristics of uniform discharge, stable operation and fast grinding speed, which ensures that the output and quality of finished machine-made sand meet the requirements.

VSI sand making machine

Annual output 120 tons-150 tons:

Configuration equipment: raw material factory, ZSW380*95 vibrating feeder, HD86 jaw crusher, HXGYS300 cone crusher, 3YK2460 vibrating screen, B800 * 20m conveyor, B800 * 2 1m conveyor, HXVSI9526 sand making machine, B800 * 30m conveyor and B650.

Features: The main equipment of this sand and gravel production process includes jaw crusher, cone crusher and sand making machine, which has a wide range of raw materials and little restriction on raw material particle size. Reasonable configuration, stable operation, suitable for medium sand factory investment. According to the particle size, the finished sand aggregate can be reasonably divided into three categories: 0-5mm, 5- 10mm and 10-20mm, so as to improve the efficiency of the production line.

Jaw crusher

Annual output of 400 tons:

Configuration equipment: raw material warehouse, 2YKW600* 130 vibrating feeder, B 1200 * 28m conveyor, B 1200 * 24m conveyor, B650 * 10m conveyor and PE900 */KLOC-0. B 1200 * 33m conveyor, HVI 1250 sand maker, B800 * 15m conveyor (4 sets).

Features: The sand and gravel production process has a strong lineup, strong working ability, reasonable and efficient configuration, and it can easily output 400 tons, meeting the requirements of large sand making plants. The finished sand aggregate has a large particle size range (0-5mm, 5- 10mm, 10-20mm, 20-40mm) and high commercial value.
