Roller Crusher
roller crusher
The Roll Crusher is to install toothed crown (toothed plate) on two main shafts which will rotate in opposite direction and then build up cutting and stretching force to break material. Main shafts pour out material directly into the whole top space of crusher by driving mechanism (single or double drive) and not restricted by crushing size. After crushing, the material will be discharged between two toothed plate and side wall comb teeth, screening and crushing are finished with shapely product granularity.
Roll Crusher Features
• Two stage crushing, designed to Combine pre-breaking and final sizing in one compact unit.
• Adjustable rolls – product sizing can be adjusted whilst the Crusher is running.
• Automatic roll relief to protect against tramp.
• Segmented Rolls for easy maintenance.
• Enclosed gearbox for long life.
• Crusher housing designed for quick access to rolls.
• Coupling mounted rolls for ease of removal.
Working Principle Of Roller Crusher:
Through the feed opening, the raw materials fall to between the two rollers, after crushed, the final products drop naturally. When there are unbreakable materials or the material is too hard, the roller will concede automatically under the effects of spring and hydraulic pressure, which will widen the clearance between the rollers and make the hard or unbreakable so as to avoid damaging the machine. The clearance between the two rollers can be adjusted to change the sizes of final products.
Applications Of Roll Crusher:

These roll crushers are available with Gundlach’s breakthrough 3-D crushing technology that includes intermeshing continuous tooth roll design and positive roll timing that delivers the industry’s best dimensional product control, fewer fines and elimination of over-size material. Gundlach’s roll crushers deliver higher quality cubical product, minimal fines and consistently repeatable performance for sizing coal, coke, glass, fertilizer, potash, salts, lime, limestone, soft ores, friable materials and industrial minerals.
Roll Crusher Capacities
Feed size: up to 1200 mm in size
Product sized to: typical products are 100 mm, 50 mm, 38 mm, down to 6 mm depending on feed size
Throughput: from as low as 10 TPH up to over 6000 TPH, depending on material, feed size and product size.
The Roller crusher can be classified into roller crusher and four roller crusher according to the roller quantity. The Roller Crusher bears the features of stable operation, easy maintenance, low cost, output size adjustable. The Roller Crusher can be used in the processing of fragile materials in cement, metallurgy, chemical, power generation, coal industries.Roll Crushers Engineered for Reliable Operation, Maximum Yield and Easy Maintenance ,From Crusher rolls to shafts and bearings, from lubrication systems to easy access housing design, Gundlach roll crushers are engineered with performance and maintainability built in.
The Roll Crusher suits for coarse and secondary crushing of various materials such as limestone, granite, iron ore, coal, etc. Its low and short main frame, rather compact and simple structure, make the weight of whole machine is lighter than other crusher by 1/2~1/3 with the same capacity. Therefore, it is preferred product for portable and semi-portable screening and crushing plants. We have three different length boxes of short case, standard case and long case for every serial to meet the needs of different capacities. And various gear teeth for every specification is available to fit different crushing and discharge the materials forcedly without jam, so it rather suits to those sticky and high water content material. This product has the properties of low power consumption and low noise, is environmental and energy conservative product.
