The following are the configuration schemes for a 400 tons/hour stone crushing and sand making production line:

1. Granite 400t/h Crushing and Sand Making Production Line Configuration

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

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

Process flow chart is as follows:

Granite material is initially screened by an F5X1345 feeder. Small materials go directly into the cone crusher transfer bin, and large materials are crushed by the jaw crusher before entering the bin. The material in the bin is processed by two HPT300 cone crushers, then screened by an S5X2460-2 vibrating screen. Large materials are recycled for crushing, and 31.5-40mm finished products are screened out. The remaining materials are then screened by an S5X2460-3 screen, finely separating four specifications of finished products: 0-5-10-20-31.5mm, completing the entire crushing and screening process.

2. River Pebble 400t/h Sand Making Production Line Configuration

Finished product size: 0-5mm high-quality sand, supplied to high-speed rail and concrete mixing plants

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

Process flow chart is as follows:

The pebble raw material is first crushed by a PEW860 coarse crusher, and then enters a regulating bin. Through a belt conveyor, the pebbles are transported to a single-cylinder hydraulic cone crusher HST250 for secondary fine crushing. The crushed material then enters the regulating bin again and is transported by a belt conveyor to a vibrating screen for screening. After screening, materials smaller than 40MM are sent to the VSI5X-1145 impact crusher for sand making treatment, finally producing 0-5MM high-quality sand as the finished product.

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