20 TPH Double Roll Crusher Equipment
,Reinforced Roller Double Roll Crusher
,Adjustable Discharge Roll Crusher
2PGT400*400 is upgraded medium-small size spring double roll crusher, roller width increased compared with 400*250 model. Technical parameters: maximum feed size ≤30mm, adjustable discharge 1-10mm, hourly output 8-20 tons, twin 7.5kW motors. The reinforced roller body improves wear resistance for continuous brick clay, shale crushing. Optimized spring sets provide larger buffer stroke to adapt common hard impurities in shale raw materials. Moderate capacity fits standalone medium-sized brick factories, small aggregate processing stations that do not require ultra-large throughput. The machine retains easy maintenance characteristics of spring roll series, daily inspection and roller surfacing repair can be completed on production site.
| Transmission Mode | Specification Model | Feed Particle Size (mm) | Discharge Particle Size (mm) | Hourly Capacity (t/h) | Power (kW) |
|---|---|---|---|---|---|
| Spring Roll | 2PGT400*400 | ≤30 | 1-10 | 8-20 | 7.5*2 |
Counter-rotating rollers compress fed materials for size reduction. Wider roller surface extends effective crushing contact length to lift hourly processing capacity. Spring buffer mechanism handles transient overload caused by gravel mixed in clay feedstock: springs shrink temporarily to release foreign particles, then restore normal roller spacing. Users loosen or fasten spring bolts to adjust discharge granularity within 1-10mm range, adapting different raw material formulation of sintered bricks, permeable bricks. Qualified materials fall out from the bottom for next molding procedure.
- Wider roller achieves 8-20t/h output, perfectly match daily raw material demand of medium brick production workshops
- 1-10mm adjustable discharge covers most particle requirements of brick making raw materials
- Robust spring overload system adapts raw materials mixed with small gravel, reduces unplanned shutdowns
- Reasonable power configuration (7.5*2 kW) balances productivity and electricity expenditure
- Universal roller spare parts compatible with 400 series models, reduces spare part inventory pressure
Shale/clay brick manufacturing plants, small lime processing factories, fine crushing of construction recycled sand, fertilizer raw material size reduction
Q1: What feed size can 2PGT400*400 handle?
A1: Maximum input particle size ≤30mm.
Q2: Whether it can stably run for 8 hours per day for brick factory production?
A2: Reinforced roller and spring assembly support long continuous operation for brick production demands.
Q3: How to adjust finished particle size?
A3: Adjust preload of bilateral compression springs to change roller clearance for different discharge sizes.
