Below are configuration diagrams for a stone crushing and sand production line with a capacity of 400 tons per hour:

1. Configuration of a granite crushing and sand production line with a capacity of 400 t/h

Finished product size: 0-5-10-20-31.5 mm

Main equipment: PEW jaw crusher, 2 HPT300 multi-cylinder hydraulic cone crushers

The technological scheme is shown below:

The granite material first undergoes preliminary sorting on the F5X1345 feeder. Fine fractions go directly to the cone crusher hopper, while large fractions are crushed by a jaw crusher before entering the hopper. The material from the hopper is processed by two HPT300 cone crushers, then screened on a S5X2460-2 vibrating screen. Large fractions are returned for re-crushing, and the finished product of size 31.5-40 mm is screened out. The remaining material is then screened on an S5X2460-3 screen, where it is finely separated into four fractions of finished product: 0-5-10-20-31.5 mm, completing the entire crushing and sorting process.

2. Configuration of a river pebble sand production line with a capacity of 400 t/h

Finished product size: high-quality sand 0-5 mm, supplied to high-speed railway construction companies and concrete plants.

Equipment configuration: European version PEW860 jaw crusher, HST250 single-cylinder cone crusher, VSI5X-1145 sand making machine

The technological scheme is as follows:

The raw material (pebbles) is first crushed in the PEW860 coarse crusher and then fed into a storage hopper. Using a belt conveyor, the pebbles are transported to the HST250 single-cylinder hydraulic cone crusher for secondary fine crushing. The crushed material is again fed into the storage hopper and transported by a belt conveyor to a vibrating screen for screening. After screening, material smaller than 40 mm is sent to a VSI5X-1145 impact crusher for sand production, resulting in high-quality sand of 0-5 mm size as the finished product.

How much does a 400 tons per hour crushing and sand production line cost? It can crush large stones of lower hardness. The jaw crusher, which is the primary crushing equipment, has a high capacity. Choosing the PE1200×1500 model with a capacity of 400-800 tons is sufficient to meet production needs. The impact crusher, which is the secondary crushing equipment, has a relatively lower capacity, so two PE1000×1200 models with a capacity of 300-800 tons per hour are used in parallel. The particle size of the finished product is adjustable, the particle shape is good, and the quality is high. Moreover, the entire stone crushing line is relatively inexpensive, ensuring high overall efficiency. The cost of such a production line varies from approximately one million to tens of millions of yuan, depending on specific requirements.
