briquette

Main features: The transmission system: Motor--Elastic coupling (belt drive)--Twin-shaft reducer--Gear coupling--two rollers. Roller structure: Mosaic structure with laminated roll sleeve. Roller material: High quality bearing steel, cold working die steel and martensite stainless steel (suitable for acid materials) Bearing assembly: return sleeve structure equipped with special tools for disassembling and assembling. Knowlege and experiance are need for the selection of roller material. Cooling system ,in particular, the selection of cooling area and the control of cooling cycle are the core technique. The cooling media can be soften water or heat transfer oil. Note: Specific crushing equipments are installed regarding to certain materials, for seperating the likely adhesive briquettes.

In practice, we noticed that not all materials need high pressure briquetting, however, some medium pressure briquette machines are even more suitable for briquetting the certain materials. The difference with high pressure briquetting is that the smaller line pressure. The line pressure from 2t/cm to 5t/cm is considered as medium pressure briquetting machine. And the common ones are 3t/cm and 5t/cm.

Briquette machine is the main equipement with the applied powder material forming technology. Its apllications can be seen in a wide range of industries. Briquetting, as a stage of the process, it could be aimed for minimizing the need of dust removal and ventilate, it could be an end-product for selling. We consider it as high pressure briquetting machine, once its line pressure is 50-120KN/cm. The common ones are 80KN/cm,110KN/cm,120KN/cm and 150KN/cm.

Technical features: The adjustable basket form has an uniform discharge with easy installation and maintenance. The whole furnace is designed as a trapezoidal shape, which is narrow at the top and wide at the bottom. So that the material will not stuck inside. The position of hot air inlet is designed at the lower middle, the pre-drying distance is long with a good dehydration effect. The upper part of the furnace is closed and the dust removal is done inside. Low wind speed carries out less dust, in the mean time, it is easier to observe the stock bin temperature, feeding and combustion condition. It uses infrared camera for monitoring and automatic alarm device for temperature control. The heat source of drying adopts boiler flue gas and automatic heating system with automatic coal feeding and slag removal. The design of double vertical air duct avoids the influence of kiln length and resistance on uniform air distribution.

In practice, some materials are difficult to shape, and the binder is unwanted. So in this case, a briquette machine with higher line pressure is needed. Generally, we consider a roller press with a line pressure ratio of more than 20t/cm is an ultra-high pressure ball press. Compared with the high pressure briquetting machine, this equipment has its unique characteristics: 1. All motors and reducer have a direct structure, which makes the transmission more accurate. 2. The application of variable pitch screw is indispensable, and it aslo brings a better result through the accurately machined prepress screw. 3. The sealing technology on both sides of the prepress screw and roller is one of the important features of the briquetting machine. Its sealing effect better ensures no pressure relief for material that under the ultra high pressure and closed environment. 4. The automatic control and protection ability are strengthened in control system.

Kaizheng has introduced a series of lab scale micro-briquetting, compacting and grinding equipments, to make it possible and convenient for scientific institutes and enterprises to experiment on different materials and find the briquetting and grinding capacity. Laboratory equipment: Briquetting, compacting and grinding experiments can be carried out continously on a very small number of various materials (about 0.3 liters per test, several kilograms per hour). Another advantage of the equipment is that components in contact with the product can be disassembled, cleaned and reassembled quickly. (the heaviest part does not exceed 10KG) Different experiments can be carried out by quickly changing the rollers. Pilot equipment: A certain amount of various materials can be briquetted, compacted and ground continuously. (at least 10 liters per test, (500-1000) kg/h ). Different experiments can be carried out by quickly changing the rollers. The design and manufacture of equipment are close to industrial equipment, which can provide reliable basis for the selection of industrial equipment.

The HGW net belt dryer is mainly used for drying ball briquettes, but also for drying lumpy materials, such as cold solid pellets, coal briquette, coke and so on. The net belt dryer is a drying equipment based on the principle of two-way or one-way conveying. The ball briquette with certain moisture is feeded into the upper grid plate of the dryer through the hopper. The feeding hopper functions as buffering and feeding. The material is convyed smoothly through the grid plate to the head of the dryer, and then flows into the lower layer by the plate-turning mechanism, and then returns to the tail of the dryer.
