ThyssenKrupp Mining Material Handling Technology Co., Ltd. (hereinafter referred to as “ThyssenKruppâ€) is a world-leading manufacturer of stand-alone and complete equipment in the mineral processing industry. The company's roll-type screening crusher has a production capacity from 50t/h up to 5000t/h; the maximum feed size of the crushed material is about 1700mm. Screening can roll crusher crushing rocks and the viscous medium hard and soft materials such as brown coal, minerals, clay, marl, limestone and similar materials.
The crushing ratio of the roller screening crusher can reach 4:1 or even 6:1. The size of the product after crushing by the roller screening crusher is clear, the rate of exceeding the standard is low, suitable for primary or secondary crushing, and the final product size can be Less than 50mm. The feeding method of the crushed material of the roller type screening crusher can adopt continuous feeding or intermittent feeding. The material is broken under the shear and tensile forces generated by the high torque at low speeds. Therefore, the power consumption rate, the wear rate, and the fine particle content of the finished product are relatively low compared to other crushers. The line speed used in the crushing process, the "novel" tooth design, the special arrow-shaped crushing tooth arrangement, can effectively handle larger feed sizes and achieve optimal clamping results with relatively small roll diameters.
The material stream impinges on the center of the crushing rolls arranged in parallel. The arrow-shaped crushing tooth arrangement not only ensures a continuous crushing process but also achieves a balanced material distribution, thereby completing the crushing process through the entire length of the roller shaft. The crushing roller can be operated by a motor drive (motor-hydraulic coupling-gear-scutter coupling) or hydraulic drive with overload protection.
The crusher features: reliable, stable and efficient technical indicators, low equipment height, and a compact, flat design; the roller screen crusher casing can fully absorb the crushing force, only the inertial force is supported by the base. The crushing method makes the fine particles in the finished product extremely low, thereby generating less dust; the low speed movement of the rotor produces strong shearing force and tensile force; due to the large spacing between the various crushing rollers, the feeding The granules contained in the granules can pass through the roller sieving crusher smoothly, so in many cases no primary screening is required; low operating cost and high efficiency; modular design: roller sifting crushers can be assembled in different series as needed Model-specific toothed rolls; symmetrical frame design; application areas include completely different materials, medium hardness, softness, brittleness, viscous material; due to the use of special materials, special crushing tool geometry and crushing methods (bending force and Low wear rate due to tensile force, relatively low circular motion speed; easy to replace broken tools.
The roller type screen crusher and its external dimensions and technical parameters are shown in the following figure and the following table.
Work Principle:
The machine is fixed by different geometry, the relative rotation of the rotor under high speed rotation, when the material under the weight, air pressure and centrifugal force through adjustable stator clearance, subject to strong shear , Friction, impact force, high-frequency vibration and other complex forces, are effectively broken, dispersed emulsification and mixing, resulting in the ideal product.
