Unitec Quadroll Hydraulic Crusher

(Quarry)

UNITEC Crushing equipment is proud to introduce this UNITEC Quadroll hydraulic crusher to the Australian Quarrying, Mining and Recycling industries.

1. UNITEC Quadroll Crusher details

All fine crushing after Jaw Crusher is carried out by only 1 UNITEC Quadroll crusher for production of manufactured sand.
Main Applications
- Producing under 5mm Fine Sand (Input size 9-25mm).
- Producing under 13mm (Input under 40mm).
- Or other fine crushing requirements for construction materials.
- Processing of recycled waste such as construction waste materials and bricks, fine concrete and asphalt aggregates.
- Fine mineral production like Gold, Silver, Lead, Zinc, Copper, Diamond, etc.
Advantages
- High efficiency and performance.
- High capacity and productivity with low wear parts costs.
- Up to 70% lowest wear cost than impact crushers and cone crushers in particular application.
- Easy replacement of wear parts.

2. WHAT IS A QUADROLL CRUSHER

General Description

The UNITEC Quadrolls is a compression type rolls crusher which is fitted with two pairs of heavy duty counter rotating rollers, arranged such that one pair of rollers sits above the other. In this configuration, feed material entering the crusher is effectively crushed twice in each pass through the Quadrolls.

The UNITEC Quadrolls is designed as a fine reduction crusher to fill the gap between
conventional cone crushers and the “super fine” performance of the High Pressure
Grinding Rolls machine (HPGR). The Quadrolls is not an HPGR and should not be operated in the same manner as an HPGR.

3. RANGE OF QUADROLLS CRUSHERS

There are four models available as follows.

3 – 1. MODELS

Model	Size (D*W)	Capacity (T/H)-Through Output	Max, Size(mm)	RPM	Power	HYD.MOTOR
Model	Size (D*W)	Capacity (T/H)-Through Output	Max, Size(mm)	RPM	Power	HYD.MOTOR
U-HQRC	0608	See Below	25	100	75KW*4P	ME600B
	0810		30	100	90KW*4P	ME850B
	1012		35	100	110KW*4P	ME1300A
	1215		40	90	130KW*4P	ME1300A

3-2. STANDARD CAPACITY

MODEL	Bottom Roll	Crushing Capacity (t/h)-Throughput
MODEL	Setting (mm)	2	3	4	5	6	7	8	9	10
Φ600 * 800L		29	43	58	72	87	101	116	130	145
Φ850 * 1000L		51	77	103	128	154	179	205	231	256
Φ1050 * 1200L		72	109	145	181	217	253	290	326	362
Φ1200 * 1500L		98	147	195	244	293	342	391	440	489

NOTES. Capacity is based on the conditions that unit volume weight is 1.6t/m3(with grain size less
than discharge setting not included)and that feed material having compressive strength
ranging from 1,000kg/cm2 to 1,250kg/cm2 This material should be fed into crusher uniformly and
continuously in quantity and grain size. The above theoretical data is based on Limestone
Of medium hardness.
