What is HGM Grinding Mill ?

HGM Grinding Mill with the international advanced level as well as several independent patented technologies and properties is the latest powder making equipment which is developed by Hongxing mechanical authoritative experts with great concentration by absorbing Germany's latest powder grinding concepts and technologies. This model of machine adopts the latest multiple patented technologies such as separated driving of bevel gears, internal lubricating system of thin oil, arc-shaped air channels etc. As a result, the machine has the following advantages: stable performances, easy operation, low energy consumption, adjustable and controllable sizes of finished products and wide application of grinding materials. The machine is equipped with special dust collector, which could make the emission concentration of dust completely below the national environmental regulations. As one kind of high efficient, energy-saving and environment-protecting equipment, The machine is with the technological characteristics as great processing capacity of single machine, easy for large-scale production and low energy consumption of unit product. Since the machine launches into the market, it earns stable performances, advanced technology and excellent public praises of customers- which passes the authentication of achievements with science and technology.

How Does a HGM Grinding Mill Work?

The materials being crushed into small particles will be sent to the storage hopper by bucket elevator, and then being sent to the host at station by the electric vibrating feeder to be ground. The grinder roller device, hanging on the star rack. rotates around the center shaft in the host, and the grinding roller turns on its own axis at the same time. The grinder roller swings outwards and presses grinding rings under the action of centrifugal force. The grinding materials can be mashed and grounded under the action of grinding rollers. The air blower blows powders to the analytic engine to be analyzed in the grinding chamber, and the fineness of the materials will fall into the host to be grounded again, and if the fineness meeting the specification, they will enter the whirlwind collecting machine following airflow and will become the finished products after being collected and discharged through discharging pipe. The purified airflow will enter into the air hlower through the pipeline on the upside of the whirlwind machine collector and grinding chamber. the wind road is circular. the pipe between air blower and grinding chamher is positive pressure. other pipe is negative pressure. The dust cannot overflow, so it can protect the environment. Thanks to the moisture in the materials will be evaporated into gas. which flows through the pipeline and the feed inlet and increases the air volume in the cycle roads, and the increased air volume will be discharged after being purified by the bag-type dust collector.

Structure of HGM Grinding Mill

HGM Grinding Mill is the upgraded and improved machine which is mainly applied in the processing of all kinds of non-flammable and non-explosive mineral materials with the Moh's hardness less than 9.3 degree and humidity degree under 10% such as quartz, feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, manganese ore, iron ore,copper ore. phosphate ore, iron oxide red, zircon sand, slag, water granulated slag, cement clinker, activated carbon, dolomite. granite, garnet. iron oxide yellow, soybean cake, chemical fertilizer, compound fertilizer, coal ash, bituminous coal, coking coal lignite, baudisserite, chromium oxide green, gold ore, red mud, clay, kaoline, coking coal, coal gangue, porcelain clay, cyanite, fluorite, bentonite, diabase, pyrophyllite, shale, purple sandstone, iterated stones, basalt, gypsum, graphite, silicon carbide. thermal insulation materials etc.

Advantages of HGM Grinding Mill

1.Improved efficiency and large production capacity

a.This kind of machine breaks through the bottleneck of processing capacity for the traditional pendulum mill and enjoys the supreme status of domestic largest processing capacity for single machine, which is 30% higher than the traditional R type Raymond Mill under the same power.

b.The technology for the linkage of grinding rollers to boost pressure could make the machine operate steadily, increase the grinding pressure and improve the processing capacity obviously.

c. Adopt high-pressure centrifugal air blower to save energy and increase efficiency.

d. Enlarged cyclone powder collector combined with air-closed unloader to increase powder-collecting efficiency.

e. There are several defectives with the integral revolving of traditional bevel gears such as inconvenient maintenance ect, if there were some malfunctions happening , the whole machine would scrap.

f. HGM Grinding Mill conquers the defectives of traditional machines and adopts the separated driving principle of bevel bears; as a result, it is easy to maintain the machine. And besides, separated driving is beneficial to adding lubricating oil to improve the lubricating efficiency.

g.The overall scaling of grinding rollers adopts Cerman technology (add oil every 15 days and maintain the machine every 6 months), which belongs to the world's advanced level.

h.The fineness of finished products can he one hundred percent adjusted from 80 to 1200 meshes at random, particle size of part materials can reach 2000 meshes at the maximum.

i. Adopting turbo-type analyzer and variable frequency motor. the machine has the following advantages: high efficiency of classification, low resistance and large processing capacity.

j. Adopt flexible connection to reduce shocking, reduce noise and increase the service life of the complete machine.

k. China's national patented product originates from Germany's latest technology and initiates the lowest records of pendulum mill's operating cost with technological innovation.

l. The original and novel internal lubricating system of thin oil has the following advantages: advanced and reliable technology, long period for changing oil, low cost of oil consumption and less frequency of maintenance.

2. Advanced Technology and Low Operating Cost

a. Original design of arc-shaped air channels, excellent liquidity of materials, low consumption of air volume and energy saving of air blower

b.No resistance entering the volute and the layout plan with same resistance could reduce the powder and energy consumption caused by the energy consumption of system greatly.

c.The machine is with special structural design of grinding rollers and rings; scraper knife with special wearing-resisting knife edge, which could increase the powder grinding efficiency and reduce the usage cost.

d.This model of equipment is very large, It can replace the tranditional design which is small machines parallel working, which could reduce the costing for labor vastly.

3. 0ne machine could be used in many aspects, so it is economic to invest in this kind of machine.

a.There is no need to change any spare parts, so one piece of equipment could reach the requirements of various kinds of materials and different particle diameter sizes of finished products.

b.Under the same processing capacity, the occupied area is only one third of R Raymond Mill. The machine has the following advantages: low cost for the infrastructure construction of workshops, economical and practical investment, quick withdrawal of funds and dramatic increase in interest.

4. Energy Conservation and Environment Protection

a.This machine is equipped with special dust collector, so there is less dust emission, and the dust removal result could be over 99.99%, which could basically realize dustless working in the workshops.

b.The noise of operation is low, vibration of machine is slight.
