2PGT750*500 belongs to heavy-duty spring roll crusher for medium-large production sites, fitted with two 22kW high-power motors, upgraded roller diameter for stronger crushing force. Technical indicators: maximum feed ≤30mm, adjustable discharge 1-20mm, hourly throughput 15-40 tons. Reinforced roller shaft, thickened spring components adapt 24h shift operation of large quarries and mines. The stronger spring buffer can absorb greater impact energy from bulk hard materials. It is commonly applied for fine crushing of pebbles, basalt after primary crushing, to manufacture manufactured sand for commercial concrete.

High-power dual motors drive thickened rollers to squeeze raw stones. Reinforced spring assemblies buffer heavy impact generated by hard rock feeding; when metal impurities enter crushing zone, springs contract sufficiently for impurity evacuation, protecting roller shaft and bearing assemblies. Operators tune spring preload to set required roller clearance to get 1-20mm finished products. Optimized roller surface texture reduces material slippage, raising crushing efficiency for hard abrasive stone.

1. Dual 22kW high power configuration supports long-time heavy load operation for large mines
2. Reinforced roller shaft and heavy spring structure extend service life under abrasive working conditions
3. Stable 15-40t/h output meets high daily raw material consumption of large concrete sand yards
4. 1-20mm flexible discharge adjustment covers fine sand and medium aggregate production demands
5. Heavy-duty bearing housing reduces lubrication maintenance frequency
