SMOOTH ROLL CRUSHER
SR11
Features
- Fast rotating rollers independently driven
- Crushing under pressure with identical roll’s speed
- Roller surface smoothed, grooved or welded
- Unique feature of roller gap adjustment by 0,1 mm
- Material evenly distributed along crushing gap
- 1 fix and 1 movable rollers, heavy hydraulic pistons
- Hydraulic loosen rolls in case of foreign bodies into gap
Advantages
- Performs a gentle crushing
- Secondary crushing between parallel rollers
- Producing perfect desired narrow PSD
- Constant and high performance
- Trouble-free, dust-free with wet & dry materials
- Overload protection hydraulically activated, to avoid damages
Application
- Comminution of hard and medium-hard material (lime stone, magnesia, salt, fertilizer, coke etc.)
- Throughput up to 500 mt/hr, depending on material characteristic and particle size
- A typical application: fine crushing e.g. from 30 mm feed size to 5 mm product size, approx. 80% target particle size largely avoiding fine grain and dust
- Crushing roll surface according to the material characteristics (smooth, machine cut grooves or built-up welded rips)
- Integration in semi-mobile plants possible
Mode of operation
- Comminution of the feed material between the two rolls (fixed and moveable) by mechanical pressure up to 200 to 400 kN, hydraulically induced
- Product particle size regulated by precise hydraulic setting of the roll gap
- Opening of the gap between the crushing rolls in case of overload (e.g. caused by an unbreakable foreign object) within milliseconds to let that piece pass thus avoiding a shut-down
