Low roll speeds ensure minimum dust and fines generation; Direct mechanical drives; Compact design with right angle gear reducers and smaller footprint allow for installation in low-headroom areas; Product setting adjustability to make up for wear or change in product size requirements; Interchangeable segments and sizing combs throughout the ...
Roll crushers apply shear or compression to the material that is going to be reduced in size. This action occurs between two hardened surfaces. The speed and diameter of the …
Here, roll crushers with round-shank bits are used. The type, arrangement and number of bits on the crusher roll largely determine the product size and are designed to specification. Reclaim Primary sizer used to crush coal while transferring it from stockpiles onto belt conveyors (can be used without the crusher roll as a simple reclaim feeder—
Crusher housing 2. Fly wheel 3. Base frame 4. Fixed roll 5. Floating roll 6. Hydraulic gap setting system Working principle Material is fed by a continuous feed arrangement into the middle of the machine between both rolls (a). The rolls operate at 5 m/s or even higher, and shear and compression forces crush the material between the roll in the ...
Due to the low crushing ration, the thyssenkrupp Polysius Double-Roll-Crusher is producing a product size ditribution with less content of fines and therefore it is the most suitable machine for the lime-industrie. Contact. thyssenkrupp Polysius . General Contact. Graf-Galen-Straße 17. 59269 Beckum
The standard model range includes 20 machines of various sizes and designs. The series is dividable into primary, secondary and tertiary sizers. In the primary crusher, a conveyable product (<300 mm) can be produced from the raw materials with a maximum edge length of 2.0 m in one-step.
For sizes < 66cm, the circumference along the opening = 8-10 x Gape; For sizes > 66cm, the circumference = 6.5 x 7.5 x Gape. Mantle diameter to Gape = 1.3-1.7:10. Feed size= 0.9 x Gape; Angle of nip varies for large crusher between 21 °to 24 °. For curved surfaces, the nip varies from 27 ° to 30 °.

Sizing teeth roller crusher is used for crushing material from 50-1500mm to 15-300mm, capacity can reach 80-3000t/h. Crushing Strength: <200mpa. Coal: Raw coal with rock and clean coal sizing. Construction Materials: Limestone, Gypsum, Marl, Clay Industrial Materials: Borax, Chalk, Kimberlite, Oil Sands Mixed/Medium Strength Ores: Gold, …
Roll crushers are used for producing finer product sizes and are often used in the mining industry. Working Principle of Secondary Crushers. The working principle of secondary crushers varies depending on the type of crusher, but generally, they work by applying pressure to the material through compression or impact.
By referring to equipment manufacturer's bulletin on crushers, Fig. 1, a crusher producing 80% passing 3/4″ requires a close side setting of approximately 5/8″. Since the selected crusher capacity must be in excess of 143 tons per hour, the next higher figure (159) is chosen. The 159 indicates a 548 crusher size with 1″ eccentric throw.
Rolls range from 300 mm to 900 mm, with roll lengths 500 mm to 3000 mm, and feeds up to 1200 mm and product sizes to 6 mm.

However, Single Roll Crushers provide limited product sizing and are limited in throughput capacity. Double Roll Crushers feature two rotating roll shafts that crush material between the teeth and roll bodies. These types of Roll Crushers produce a cubical product with minimal fines generation, and can handle higher capacities.
The Double Roll Crusher crushes a wide range of material types reaching compressive strengths of up to 150 MPa and even above. It is less sensitive to wet and sticky material than Roll Sizers and can take in larger feed sizes making it the optimal primary crusher for soft and medium hard rocks.
