  • High/Low Torque Alarm on Vertical Roll Mill in Cement

    The company can now see exactly when the torque spikes and how that relates to the material input to the roll mill system. The “High Torque Alarm” function will prevent any further damage to the gearbox, thus reducing downtime for the operation.

  • Roll Torque an overview ScienceDirect Topics

    Equipment: All experiments were carried out on a two high, experimental Stanat mill, fitted with grooved rolls of 135 mm maximum diameter x 200 mm face width, made of H13 tool steel hardened to Rockwell C55. The surface finish of the rolls was obtained by sand blasting. The mill is driven by a 15 kW constant torque, DC motor. The two drive spindles contain the torque transducers to measure

  • 4-High Rolling Mills Metal Processing Machinery

    The biggest advantage of a 4-high mill is that the work roll can be large or small in diameter and allow for substantial reduction because the area under the roll is substantially reduced. The work rolls can be large in diameter which allows large spindles and universals or flex couplings to transfer substantial torque into the work roll. They can also be equipped with dual motor drives so

  • 3 High Rolling Mill Element

    Rolling mill consisting of three rolls or known as 3 High rolling mill is typically used for performing multiple reduction passes by wrapping material around the center mill roll and performing another reduction on the opposite mill roll pair. 3 High mill can also be used with varying mill roll sizes to induce a specific percentage of reduction of material on a single side of the work piece.

  • Cold rolling mill 6-high ANDRITZ

    In comparison to a 4-high mill stand, the utilization range is wider. This type of rolling mill is mainly used in offline applications for cold rolling of soft and medium strip and for a wide range of strip widths. Strengths and benefits of the 6-high cold rolling mill. Rolling technology for highest quality standards; Proven and sophisticated design; Meets the most exacting requirements

  • 6-High Rolling Mills Metal Processing Machinery

    A 6-high mill also allows for substantial roll shape, depending upon the horizontal movement of the rolls. Another advantage of a 6-high mill is a larger work roll which can transmit considerable torque and allow for high speeds up to 7,000 FPM. Large diameter, light gauge coils can have thousands of lineal feet, and unless the speeds are substantial, (4,000 to 7,000 FPM), the cost of making

  • 20-High mills SMS group

    20-HS mill rolling mills from SMS Group technology that pays off. You benefit from our 20-high mills because they are packed with state-of-the-art mechanics, hydraulics, electrics, and automation. Plus: it’s easily possible to retrofit these features into existing mills.

  • High Pressure Grinding Roll for advanced crushing |FLSmidth

    The initial investment in a high capacity High Pressure Grinding Mill certainly pays off. The superior construction and energy-efficient capabilities of the machine mean lower costs to operate and maintain. Low cost to you means higher margins. Short shutdown for wear part replenishment You simply can’t afford to shut your operation down frequently to replace wear parts. The wear parts

  • POWER IN ROLLING

    The torque is equal to the product of total rolling load and the effective moment arm. Since there are two work rolls Torque Mt = 2P.a Consider two high roll mill as shown in the figure. For one revolution of the top roll the resultant rolling load P moves along the circumference of a circle equal to 2π.a

  • Understanding Rolling Process in Long Product Rolling Mill

    Calculation of roll force is important because calculation of torque and power in a rolling mill is based on calculation of roll force. Accurate prediction of roll force for grooved rolling is considerably more difficult than predicting the geometry of the rolling stock. There are essentially three problems, present during the rolling as well but somewhat easy to handle. They are (i

  • High Pressure Grinding Rolls 911Metallurgist

    HPGR roll diameters typically range from 0.5 m to 2.8 m, depending on the supplies, and roll widths vary from 0.2 m to 1.8 m. The aspect ratio of the rolls also varies as a function of manufacturer. Typical HPGR throughput rates range from 20 to 3,000 tph, with installed motor power as high as 3,000 kW per roll. The roll surface is protected with wear-resistant materials, and it has been these

  • Cold rolling mill 4-high ANDRITZ

    The 4-high mill is equipped with positive and negative work roll bending in order to influence the shape and the flatness of the strip. Either the work roll or the back-up roll is driven, depending on customer requirements. The diameter of the 4-high work rolls amounts to approximately 1:4 in relation to the barrel length. This type of rolling mill is mainly used in offline applications for

  • A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL

    on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K.
