Dawn vertical mill grinding process in the mining widely used – Stone texture ma
Milling process is broken ore mines in the mineral processing of the most critical process, Grinding Technology is an important technique in mineral processing. How to select high-performance, low power crusher, milling machine equipment, is to ensure normal production of the key mining enterprises.
In actual production, there are different kinds of crusher specification, different scope of use. Currently selected plant of multi-purpose broken or cycles of jaw crusher cone crusher; the broken standard type cone crusher; petty type with short head cone crusher.
Broken in the mines, milling process, the ore crushing operations in the relatively coarse crushing big job broken, so broken loose of its larger volume have increased. To prevent crushing machine crushing chamber may give rise to obstruction, without increasing nesting population to ensure that the necessary premise of size marker to be broken by increasing the diameter of the bottom cone to increase the total cross section marker. Mine production of commonly used cone crusher is mainly broken in the conventional grinding process as the third paragraph of the second paragraph of broken and broken to use. In recent years, more widely used abroad, the domestic market, the use of cone crusher with the exception of mining, the principal is also imported a large cone crusher. Currently, the world's cone crusher in the mine mouth 25mm row conditions, the maximum processing capacity of up to 1200t / h.
Vertical mill vertical mill is a vertical installation, with a fine grinding equipment mixing equipment. Material from the mill into the lower part to give the material into the ground by the media, the qualified product because the density of the reasons the top of the overflow from the mill, while coarser particles continue to stay in the mill was grinding. Established to mine the largest mill size is 6mm, product size 74 ~ 2 m. Currently, the largest foreign legislative mill installed power 1500HP, processing capacity of up to several hundred t / h.
In the mine production, there are other types of crushing, milling machinery, from its working principle point of view, advantages and disadvantages.
A, roller mill: by rotating rollers crush the material.
B, disc mill: The vertical axis or horizontal axis of the disk rotating as the broken parts.
C, centrifugal mill. High-speed rotating parts and media production capacity to complete the crushing effect of centrifugal force.
D, vibrating mill. Produced using high-frequency vibration shaft, so that media and materials to complete strike against each other and crushing effect.
Liming Heavy Industry Vertical Mill is widely used on the basis of advanced technology, combined with years of experience in a variety of mill production, design and development of advanced grinding equipment. Is a set of crushing, drying, grinding, milling grade transport industry in one ideal. LM Series Vertical mill are widely used in cement, power, metallurgy, chemical industry, non-metallic mineral industries. Used to block, granular and powder materials ground into powder material required.
Liming Heavy Industry Vertical mill grinding efficiency, and the milling system, energy saving 30% compared to 40%. Wear less, drying ability. Equipped with automatic control system, remote control, easy to operate. Equipped with a roller cover and the disc to prevent direct contact liner device to avoid damaging shocks and severe vibration. Through the maintenance of tanks, turn rotation arm to replace roller cover, liner convenient and less downtime. Running, small vibration, low noise, and the overall sealing device, the system under negative pressure of work, no dust spill, clean environment, to meet national environmental requirements.
