Sizers. A distinct class of roll crushers is referred to as 'sizers.'. These are more heavily constructed units with slower rotation, and direct drive of the rolls rather than belt drives.
Weld-on crusher teeth are helping mines reduce downtime and increase productivity. In all crushing applications, the end user experiences wear on their crushing elements, whether it be jaw dies, Cone Crusher liners, Horizontal Shaft Impact Crusher blow bars or the rolls in Roll Crushers . If one was able to extend the life of these …
The overall structure of the machine. From the perspective of the overall structure, the cone crusher is 1.7-2 times heavier and 2-3 times higher than the jaw crusher with the same feeding opening size. A Larger machine means higher site costs . 4. Material handling.
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.

How Quad Roll Crushers Work. Quad Roll crushers are designed for larger feed sizes and high ratios of reduction at high capacities. The top stage of the Quad Roll crusher is essentially made up of a double roll crusher, which is designed with the appropriate diameter rolls and tooth configuration to readily grab the incoming feed material.
AT-Crushing Technology provides a comprehensive comparison between various crushing techniques and their manufacturers. We are excited to present …
In contrast to a Double Roll Crusher, the basic concept of the Mineral Sizer is the use of two rolls with smaller diameter shafts, because of the operation at a lower rotational speed by a direct high torque drive system. This design produces three major principles which all interact when breaking materials using sizer technology.
The obtained fractal dimensions of the particle size distributions for the particles crushed by the jaw, cone, and roll crushers were in the range of (2.16–2.38), (2.13–2.31), and (2.23–2.46 ...
The Roll Sizer is capable of crushing medium-hard rock as well as sticky and soft material such as coal, clay, marl, limestone and similar raw materials. Mode of Operation The material is crushed by shear- and tensile forces generated by high rotor torques at a low circumferential speed.

Types of Roll Crushers. There are 4 major types of roll crushers used in the construction industry: Single Roll Crushers. Single-roll crushers consist of a wedge-shaped crushing area. The materials are crushed by the shear pressure and stress of the crushing area. These crushing machines are used for compressing soft to medium-hard …
By comparison the inter-particle compression in a High Pressure Grinding Roll has a more even effect on the entire feed, resulting in a high ratio of fines without the wide PSD. Inter-particle compression is achieved by two counter rotating, similarly sized rolls, which synchronously operate at variable speeds, forcing particles to crush one ...
