The equipment configuration of the stone crusher production line with an hourly output of 300 tons is as follows:

PEW Jaw Crusher: As a primary crushing equipment, it undertakes the task of rough breaking of raw materials. The model adopts deep V-shaped crushing cavity design, the angle is more reasonable, and the crushing efficiency is 15%-20% higher than that of the traditional model. The key components are made of high-strength steel castings, and the moving jaw assembly is optimized by finite element analysis, and the bearing capacity is increased by 30% to ensure the efficient initial break of potassium sodium feldspar. Feed particle size can reach about 1000mm, broken to 250mm below the intermediate products.

HST single cylinder hydraulic cone break: to achieve secondary crushing process. Its unique spindle fixed, eccentric sleeve rotating around the spindle structure design, with hydraulic adjustment discharge port and iron protection function, so that the product size is more uniform. The PLC system can monitor the spindle position and pressure changes in real time, and can automatically reset when encountering unbreakable materials, reducing downtime. This section of crushing will further process the material to below 40mm.

VSI6X impact crusher: As the core sand making equipment, it adopts four-port rotor design, and the peripheral guard plate can be turned up and down after local wear, thus prolonging the service life. The optimized emission port and internal smooth curve reduce the material flow resistance, make the potassium albite realize selective crushing under high-speed impact, effectively control the over-crushing phenomenon, and ensure the excellent gradation of 0-5mm finished sand.

S5X vibrating screen: box vibrator and ring groove rivet connection structure, high screening efficiency. The multi-layer screen configuration can adjust the particle size distribution of the finished product according to the demand, and the screen body is optimized by finite element analysis, which can still maintain stable operation under large vibration load. The supporting spring damping system can reduce the dynamic load of the equipment on the foundation and reduce the transmission of the vibration of the plant structure.

Production line core technology advantages

Full process automation control system

The production line adopts a distributed control system to realize intelligent linkage between equipment and automatic parameter adjustment. The central control room can monitor the current, temperature, vibration and other key parameters of each equipment in real time, and automatically alarm and take protective measures when an abnormality is detected. In particular, a closed-circuit cycle is established between HST cone breakage and VSI6X sand making machine, and the cone breakage discharge port is adjusted through online particle size analysis feedback to ensure that the particle size of materials entering the sand making section is always within a reasonable range.

product quality control system

Through the reasonable coordination of the three-stage crushing process, the sand-forming rate is high. VSI6X sand making machine adopts the combined crushing mode of "stone hitting stone" and "stone punching iron", which makes the sand particles have moderate edges and corners and suitable surface roughness.
