Hongxing machinery sand making machine is widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building sand, stone and a variety of metallurgical slag, especially for silicon carbide, silicon carbide, sintered aluminum sulfate soil, the beauty of sand contour hard, special hard and corrosion-resistant materials is higher than other types of crushers yield efficacy. In the field of engineering infrastructure, sand, cushion material, asphalt concrete and cement concrete aggregate ideal production equipment. To improve equipment operation rate and reduce the rate of failure or accident, reduce maintenance costs, extend the life of the accessories or equipment, to improve the operation rate, total reducing equipment maintenance costs.As the largest domestic mining crushing machine, grinding machine, sand making equipment androtary drum dryer manufacturing enterprise, Hongxing machinery has a long-term study on the sand industry market, and has unique planning in building sand.
Our sand maker engineers point out: the new type sand maker has many advanced features; with wheels on the basis of original sand maker in order to save energy and improve the kinetic energy. It makes the efficiency improved. There is adjusting device of impact plate to control the needed fineness of the product. The earliest sand maker only has one observation door in the back, which is not in favor of observing and maintaining the operation of equipment when it works. This new type maker has a observation door in one side, which brings big convenience to workers.The role of the lifting board of the dryer machine is lifting up and scattering the material, increasing the contact area of the drying material and hot air and speeding up the heat and mass transfer to improve the thermal efficiency of drying.
The lifting board of the dryer machine lift up the material and make the hot flue gas contact with the material more fully in order to achieve the goal of better drying. The size, shape and arrangement of the lifting board have a great impact on the yield and quality and the thermal efficiency of the dryer machine. Theoretically speaking, the drying process of the material can be divided into three stages, namely heating, constant speed drying and falling rate drying. The main function of the lifting board of the dryer machine is guiding material, current-sharing, lifting up and resisting material to orderly control the movement and drying process of the material in the cylinder body. Therefore, the structure forms of the lifting board should be arranged and produced according to the physical and chemical properties and characteristics of each drying process of different material.
