Optimising the operation of the roller sand making machine to improve the rate of finished products requires a comprehensive approach from the adjustment of equipment parameters, material management, maintenance and intelligent control and other aspects. The following are specific optimisation measures and technical points: 1. Precise regulation of equipment parameters Roller clearance and pressure adjustment Roller gap directly affects the particle size distribution of the material. By adjusting the gap size, the degree of material crushing can be controlled to avoid excessive crushing or insufficient crushing. For example, too small a gap can lead to over-crushing of the material, increasing the proportion of powder; too large a gap may reduce the yield. Combined with hydraulic or spring pressure regulating system (e.g. 11-18MPa pressure adjustment of Yuhui Heavy Industry equipment).? It can adapt to different hardness materials and balance the crushing efficiency and finished product quality. Match the rotating speed with the feeding quantity The speed of rollers should be dynamically adjusted according to the hardness and size of materials. High speed may increase the output but it may lead to poor grain shape (e.g. more needles and flakes), while low speed may reduce the efficiency.? At the same time, the…
How to adjust the roll gap of roll crusher is the key operation to control the granularity of the material and ensure the efficient operation of the equipment, according to the market common 3 different structure types of roller crusher, mainly through the following methods to achieve: 1、Wedge device adjustment Change the position of the wedge by rotating the adjusting bolt: Increase the gap: Pull up the wedge block, the movable roller is pushed away from the fixed wheel, and the granularity of the discharged material becomes larger. Decrease the gap: the wedge block moves downward, the spring presses the movable roller, the gap is reduced, and the grain size of the discharged material is finer. 2、Adjustment of gasket Increase or decrease the shims between the frame and the movable bearing: Increase shims: the gap between two rollers increases, suitable for coarse grain size demand. Decrease shims: the gap is reduced, the material is finer. This method requires downtime operation, and the bolts need to be re-tightened and tested after adjustment. 3、Hydraulic adjustment method (applicable to fully hydraulic roller crusher) Adjust the distance between two rolls directly through the hydraulic system control panel, real-time display of values, higher precision. Steps:…

These materials include river pebbles, coke, coal, ceramic raw materials, quartz, limestone, shale, chalk, bricks, slag, clinker, feldspar, gypsum, salt, and other solid materials. The main body consists of two rollers that rotate in opposite directions. The conveying equipment feeds brittle material into the weighing bin, which contains a weighing sensor. The feeding device then moves the material into the gap between the two rollers. The rollers pull the material into the gap, where they press it into a dense material cake. The material cake falls from the gap and exits through the discharge hopper, where the conveying equipment carries it away. In the next stage, the material cake undergoes further dispersion or grinding. Product features of limestone high pressure roller mill 1. The hydraulic system makes it…
