Vertical Grinding Mill

Features of VM series Vertical Grinding Mill :

VM series Vertical Grinding Mill is a kind of large scale powder mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of research of mills, vertical grinding mill is designed and manufactured based on our advanced design idea, in combination with the european technology and the market demand.

VM series Vertical Mill (VM series Vertical Grinding Mill,Vertical roller mill) is a newly improved grand mill equipment after many years’ concentrated design according to a market need. The equipment is designed to solove the problem of technological problems of low production, high energy consumption and developed on bassis of absorbing advanced european technologies.

VM series vertical grinding machine is the ideal substitute of the traditional grinding mills like Raymond grinding mills, high pressure suspension grinding mills, ball mills, etc. Nowadays, vertical grinding mills have been widely used in cement, power,metallurgy, chemical and nonmetalliferous ore industries. The LM series vertical grinding machine is widely used to grind lumpy, granular and powdery material to the required size.

Features of VM series Vertical Grinding Mill:

1. Low running cost:
(1)It has high grinding efficiency, the mill adopts roller and material bed to press and grind materials. It’s low in consumption, and its electricity consumption proportion can be 40% to 50% lower, with increasing of moisture of raw materials, electricity saving can be more obvious.
(2) Low wear of mental, side plate and roller are of special materials, long life span, which is able to reduce running cost and generate higher untilizing ratio;
(3) Exterior circulation device is installed, which is able to reduce electricity consumption further.
(4) Size of feeding material is big, which is about 5% of roller’s diameter, generally 40-100mm, thus secondary crushing can be eliminated because of big and medium vertical mill.

2. Low construction expence:
(1)The vertical mill is simple in process, comparing with ball mill, its soil taking can be about 50% reduced, construction expense can be reduced by about 70%, which is small in construction area and space.
(2)The vertical mill is a combination of crushing, drying, milling, grading and transferring, which has simple system and compact structure. It can be allocated in the open air and its construction expense will be lower.

3. Operation is easy and reliable:
(1) Automatical controlling device is installed, which can enable long distance controll and is simple in operation.
(2)There is a device to prevent direct contact between roller and mill plate, which can prevent the equipment from fragmentation serious vibration.

Technical Parameter Of VM series Vertical Grinding Mill :

Mm to inch conversion: 25.4millimeters=1 inch
The humidity and hardness of raw material will affect the fineness and capacity.
