High-pressure Ball Press Machine

Introduction of the JNHM:
The JNHB, environment-friendly and intelligent, is researched and developed by our company self with the principle of making the powder be shaped by high extrusion pressure. It consists of extrusion rollers which roll synchronously in opposite rotation direction. On the surfaces of the two rollers there are many pits with specific shape. Powder, fine material or other material will be fed down to the top of the two extrusion rollers, into the extrusion angle between the two rollers. Then the transmission force and the hydraulic force pressed on the two rollers will make the material forcibly be extruded into the pits on the roller surfaces, compressed, and shaped as a specific shape. Then with the rollers roll, the shaped products will fall down with the gravity and the inner elastic force of the material.


JNHB are widely used in mining, coal, metallurgy, medicine, chemical industry and other fields, and used to make many material shaped, such as coal powder, fine iron powder, metal chips, kinds of mineral slag and mineral powder, slurry in metallurgy, coal slurry, magnesium material, refractory material and others. JNHB is featured with small size, high efficiency, no contamination, low energy consumption and most application. We especially display a test machine with linear pressure 300KN/cm to make tests for our customers.

Advantages and Features:
Advanced performances are noted below compared with the same machines from German and China.
1. High energy saving: having remarkable energy saving effect, electricity consumption per ton is half of the ordinary ball press machine, and the weight of the whole machine is two-thirds of the same specification
2. Environmental protection: the shaped pellets has high compressive strength with 1300N, good anti-drop and anti-extrusion properties. And it has no pollution to the environment during the storage, especially in the course of the transportation.
3. High intelligence: Fully automatic operation, lower work force cost, and providing convenient and fast remote service.
4. High pressure: linear pressure of our machine can reach to 300KN/cm, which is the biggest linear pressure both here and abroad. It gives a good solution to the problem of hardly making the material shaped without additive agent.

Technical Parameters for Other Models:

   

Assembly On Site:

The inlaid rolling skins are easy to exchange and has long service life, The customers can remove & replace by themselves without making back them to the manufacturer. Inlaid rolling skins have low cost and light weight, It is 2-3 times the service life than the whole ring set.

Application in iron-carbon pellet
   
At present, blast furnace generally adopts sintered ore and baked pellets, i.e. blending iron refined powder, coke powder and alta-mud, pelletizing, high-temperature sintering in the belt-type or pan-type sintering machine, or blending the iron refined powder and alta-mud, pelletizing by pan-type granulation, roasting in the vertical furnace, and smelting in the blast furnace after cooling. The roasting of the both burdens need high temperature and consumes huge amount of resources while heating, which will result in badly environmental pollution and greenhouse effect. However, if mixing iron refined powder, coal powder and binder together, pelletizing by ball press machine, becoming into iron-carbon pellets with high cold and hot strength and good tumbler strength after low temperature maintenance, and then directly putting into blast furnace for smelting, it will not only reduce roasting process, save huge amount of energy, reduce blast furnace smelting cost, but also reduce badly environmental pollution and greenhouse effect, cut raw material cost in metallurgical industry, and improve profitability. On the other hand, the adoption of such new process can reduce half of smelting time for each furnace, improve the utilization ratio of furnace a lot and finally increase the benefit of enterprise.

Right now, the iron-carbon pellet production line with cooperation of ball press machine developed by our company and new-type binder is able to guarantee the materials input for blast furnace smelting, promote to improve the process of iron-carbon pellets directly smelting in the blast furnace, which is not only environment-friendly, consumption reducing, and economical benefit increasing, but also a process revolution of blast furnace smelting in metallurgical industry.

The application in other fields
The ball press machine enjoys wide usage in industries such as industrial wastes, power plant wastes, magnesium metal, gas coking, high phosphorous oolitic haematite and blast furnace smelting. Therefore, the birth of the ball press machine provides necessary conditions for improving pellets strength, increasing working efficiency, especially for mass scale pellet industrialization production.
