High pressure ball press

High pressure ball press belongs to a type of ball press, as the name suggests, it refers to a ball press equipment with relatively high pressure. Structurally speaking, it is not fundamentally different from ordinary coal pellet presses. It is also driven by a motor belt to a reducer, and the roller is rotated by a split gear to ultimately complete the balling of powdered materials. But this is only a superficial phenomenon. Due to the increase in molding pressure, all components of the system need to be strengthened accordingly. For example, the body needs to be more compact, the heat treatment hardness of the roller skin needs to be higher, the gears cannot be made of ordinary cast steel anymore, and the tightening system of the rollers cannot use traditional nail fixation methods. A series of work needs to be done, some of which cannot be intuitively reflected through modifications.

High pressure ball pressing machine is mainly used for various powders, powders, waste materials, and waste residues. The materials produced by the ball pressing machine are energy-saving, environmentally friendly, easy to transport, and improve the utilization rate of waste materials. It has good economic and social benefits.
Application fields of high-pressure ball press machine
High pressure ball press is mainly used for ball making and block making of non-ferrous and black metal powders, which can be directly melted into the furnace to increase added value. All metallurgical industry waste and auxiliary materials that need to be put into the furnace require a ball press machine to complete. For example: dust removal ash, sludge, oxide skin, steel slag, iron concentrate powder, aluminum ash powder, silicon manganese ore powder, and so on.

By quantitatively feeding, ensure that the material can enter the rollers evenly. The electromagnetic speed regulating motor provides power for the spiral feeding device, and the screw reducer rotates. The material enters the main feeding port through the belt. Among them, the electromagnetic speed regulating motor has a constant distance characteristic, so in order to press stable quality pellets, it is necessary to ensure that the material content of the spiral feeder is equal to the material content required by the host, that is, the two are balanced. If the feeding amount is too small, it will not form a ball; If the feeding amount is too large, it will cause electrical overload of the feeding device. Therefore, the normal operation of the ball press cannot be separated from correct operation and proficient skills. The electromagnetic speed regulating motor provides power to the host, which is transmitted through the belt pulley and cylindrical gear, and finally transmitted to the drive shaft through the rod pin coupling. The main function of an open gear is to coordinate the active shaft and passive shaft, ensuring their synchronous operation. The passive bearing is located behind the front end of the hydraulic protection device piston rod. Under the action of the hydraulic pump, high-pressure oil is pressed into the hydraulic cylinder, causing axial displacement of the piston. If the metal block enters between the two pressure rollers or if there is too much feed, it will cause the hydraulic cylinder piston rod to be overloaded and the hydraulic pump to stop. At this time, the accumulator can buffer pressure changes, and the overflow valve will automatically open. By changing the position of the piston rod, the distance between the two pressure rollers can be increased. Hard objects or excessive materials can pass through the rollers, and the equipment can resume normal operation, ensuring the safety of the rollers.
Our company's high-pressure ball pressing machines all use spiral feeding devices, which are driven by speed regulating motors and driven by pulleys and reducers to force materials into the feeding port. The high-pressure ball press machine is equipped with protective devices, which not only ensure the normal operation of the machine, but also provide protection for the operator, making the operation of the machine more convenient.

The high-pressure ball pressing machine produced by Gongyi Tengda Machinery has been used and improved in industry for many years. Compared with other similar products, this series of ball pressing machines has obvious advantages such as high ball forming rate, low power consumption, compact structure, and easy maintenance and debugging. This machine has a wide range of applications. After compression, the material can reduce dust, control bulk density, be reused, and improve transportation characteristics. The design of production capacity is mainly used for the pellet material in the magnesium refining process of the Pidgeon method by dry powder pressing.
