  1. JHMC has already had several decades of manufacturing experiences of crushing and grinding equipment.Early in 1957, JHMC successfully trial-manufactured the first set of crushing equipment——Jaw Crusher. In 1880s, JHMC started to manufacture the supporting machine of the boiler used in power plant——steel coal mill, and gradually made it form into series. The market shares of the products manufactured by JHMC is at leading position in the same industry of the same products. Since 1996 JHMC has started to manufacture parts of the vetical coal mill for Mitsubishi Heavy Industries ltd which has enlarged products exporting of the company, improved the manufacturing capacity of the company, and verified the quality of the products of the company.

The main bearing of MG series steel coal mill of our company is adopted by double circular self-aligning hydrostatic -dynamic bearing.The ring type sealing structure has solved the oil-leaking problem;the service life of material input-output parts can be extended and the repairing cost can be lowered by installing more wear movable liners in the material input-output hoppers;we designed the new type of low-speed transmission device of the coal mill all by ourself. This device adopts new structural gear motor which has the advantages of small size, new structure, easy to install and maintain, etc. and this product has gained the national patents; the girth gear adopts oil jetting lubrication device. It can form a even fog oil film, which has the advantages of oil saving, atuomatic timing, lubricating homogenization, etc and can reduce the gear surface wear, and improve the service life of the gear; the sound insulation device adopts the new type of fixed sound insulation cover, whose inner part is equipped with sound absorption material and damping material which obviously lower the noise.

MG steel ball mill is low speed cylinder steel coal mill which is the main equipment of the coal powder preparing system of the thermal power plant. At the same time, it is also adopted to many powders preparing system such as cement industry, metallurgy industry, chemical industry, sugar preparing industry, etc. These series products have many advantages such as compact structure, easy assembling and maintaining, stable operation, etc. They are widely used for grinding coal or other raw materials that can be grinded of various hardness.

The working principle of the ball mill is that there is a certain amount of grinding media——steel balls, being installed in the inner of it’s rotating part.When the rotating part rotates, the steel balls will be lifted to a certain height by the rotating shell under centrifugal force and friction force, and will fall down because of their own gravity. Then coal sheets entered the shell will become powder under the impact force and the grinding force of the falling dowm steel balls.

  1. Ball Mill

Ball mill is fit for grinding mining stone and other raw material that can be grinded with various hardness. It can grind all kinds of materials that are suitable for grinding till the required sizes according to the processing requirements. It can be widely used in many industries such as metallurgy, mining selecting, building, chemical, and ceramic etc.

3. Cement Equipment
The roasting rotary kiln is the main equipment for making cement in dry way. The raw material will be put into the rotary kiln from the outlet of the kiln, and it will gradually become into clinker after it is heated in the kiln and will come out from the kiln head.
Vertical Mill: the use of this kind of mill is very wide such as fine grinding of hard, medium hard or soft material in construction industry, especially in cement industry, ceramic industry, and coal, chemical. And power departments, etc. For example it can grind clinker, limestone, clay, and coal, etc. When there is hot air in the mill, it can heat and grind the raw material at the same time.
Jinan Heavy Machinery Joint-Stock Co., Ltd is the professional manufacturer of seamless steel pipes. JHMC can manufacture the whole sets of equipment of the seamless steel pipe production line, such as piercer mill units, pipe rolling mill units, sizing mill units, and straightening units, etc.. JHMC has self-research & development capability and has set up good cooperation relationships with many domestic designing institutes.
