2PGT400*250 belongs to compact spring type double roll crusher, the smallest specification of the 2PGT product lineup. It is equipped with two 5.5kW drive motors, maximum allowable feed particle size ≤25mm, adjustable discharge granularity ranging from 1mm to 8mm, stable hourly production capacity 5-10 tons. The built-in spring buffer structure can absorb instantaneous impact when hard foreign matter enters the crushing chamber, avoid roll shaft damage. Its small floor area, lightweight frame make installation extremely convenient, no large concrete foundation required. Users can adjust spring preload to change roller gap freely for different finished grain requirements. This model is widely chosen by small sand yards, mineral processing laboratories, brick factories for low-yield fine crushing work.

Two parallel rollers rotate toward opposite directions, raw materials fall into the roller gap from upper feeding inlet, get squeezed and ground by rotating rollers to form fine particles. When iron blocks or ultra-hard stones accidentally enter the crushing zone, compression springs on both sides will contract automatically to expand roller clearance, let foreign objects pass through smoothly, then springs reset the rollers to original working position. Finished materials with required size drop directly from the bottom discharge outlet. Operators adjust spring tightening degree to modify roller spacing, realizing 1-8mm discharge size adjustment without replacing spare parts.

1. Ultra-compact dimension, flexible layout for narrow workshop, movable mounting frame optional for temporary operation sites
2. Spring overload protection reduces roller breakage risk, lowers unexpected maintenance cost for small-scale production
3. Minimum discharge reaches 1mm, delivers ultra-fine crushed products for fine sand and powder raw material production
4. Low power consumption (two 5.5kW motors), greatly cuts electricity cost of small-batch long time operation
5. Simple structure, roller skin can be replaced on site without professional large hoisting equipment

Laboratory ore sample crushing, small brick factory raw material processing, miniature sand production line, construction waste fine crushing for road bedding material
