Powerful equipment for making materials into balls–briquette press

Ball press is also called: strong briquette press, mineral powder briquette press, double roller briquette press, etc. It is a kind of equipment that presses powdered materials into balls. The application of briquette press is extremely wide. It can press, granulate or press the following materials, such as aluminum chips, activated carbon, alumina, bauxite, caustic soda, charcoal, clay, coke chips, coal, cryolite, fertilizer, plastic, limestone, pigment, urea, potash salt… and so on.

The purpose of briquette press is to reduce dust, control bulk density, return utilization, improve transportation characteristics, etc.

The design of briquette press capacity is mainly used for pressing dry powder into pellets in the Pijiang magnesium smelting process. It is widely used in refractory materials, power plants, metallurgy, chemical industry, energy, transportation, heating and other industries. The materials formed by briquette press are energy-saving and environmentally friendly, easy to transport, and improve the utilization rate of waste materials. It has good economic and social benefits.

How does the ball press/briquette work?

In order to make the material into balls under high pressure, a pre-pressing screw is used to force the formed material into the middle of the rollers. Due to the constant speed reverse rotation, the material is compressed and formed. The unit pressure increases from small to large until the center line of the rollers “0-0”, and the forming unit pressure reaches the maximum value. As the rollers continue to rotate, the forming pressure continues to decrease, and the ball is released until the ball is released.

Among them, the main machine of the ball press is powered by an electromagnetic speed regulating motor, which is transmitted to the driving shaft through a pulley, a cylindrical gear reducer, and a rod pin coupling. The driving shaft and the driven shaft are synchronized by open gears. A hydraulic device is installed behind the passive bearing seat. The screw feeding device is driven by an electromagnetic speed regulating motor, which rotates through a pulley and a worm reducer to force the pressed material into the main feed port.

Due to the constant torque characteristics of the electromagnetic speed regulating motor, when the pressing amount of the screw feeder is equal to the amount of material required by the main machine, a constant feeding pressure can be maintained to stabilize the quality of the pellets. If the feeding amount is too large, the feeding device will be overloaded; if the feeding amount is too small, no ball will be formed.

Therefore, skilled operation skills are an important condition to ensure the normal operation of the energy-saving ball press.

The hydraulic protection device is a hydraulic pump that pumps high-pressure oil into the hydraulic cylinder to cause the piston to produce axial displacement. The front joint of the piston rod is against the bearing seat to meet the production pressure requirements.

When there is too much feeding between the two rollers or a metal block enters, the hydraulic cylinder piston rod is overloaded by pressure, the hydraulic pump will stop, the accumulator will buffer the pressure change, the overflow valve will open and return oil, and the piston rod will shift to increase the gap between the rollers so that hard objects can pass through the rollers.

The system pressure returns to normal and the rollers can be protected from damage. The Smat Ball Press Machine can adjust the pressure according to the requirements of the ball density, and the production is flexible. In addition, the ball press is also used for the ball making and agglomeration of non-ferrous and ferrous metal ore powders, which are directly put into the furnace for smelting to increase the added value.

All waste materials and auxiliary materials in the metallurgical industry that need to be put into the furnace need to be completed by the ball press. For example: dust removal ash, pond mud, oxide scale, steel slag, iron ore powder, aluminum ash powder, silicon manganese ore powder, etc.
