Marble Process Specification and Coal Miner Equipment

Marble Process Specification

Marble process has to go through several steps, a few things to remember when working on marble processing: always work throughly on each stage-never try to skip a stage or skim over a stage quickly. Always give the finish the customer wants-not all customers will be looking for a highly polished, perfect marble.

Marble processing line can be used as the building materials of walls , table ,floor, and column. And also be used to carve various practical crafts like arts and crafts, stationery.

The Process of Lead Mining

Lead ore mining process was always very hard and dangerous work. From the early 1740's until around 1890 mining was usually done by one man holding a chisel while his partner hit it with a sledgehammer. Once a suitable hole was created, gunpowder was placed in the hole, a straw fuse attached and lit. After the explosion when the dust had settled, the men would then break up the rock and the lead ore would be taken to the surface for processing.

There were many accidents from falling rock loosened by explosions and from premature ignition of the gunpowder leading to loss of life or limbs. The mines were very dangerous places in which to work.

Coal miner equipment

Clean Coal Plant Sand washer can be used to get rid of the dust in sand. coal miner equipment aims at improving the quality of sand. The materials are the required gravel in building-site, gravel factories, hydropower station and concrete dam site, post and electric pole factory, casting-70 sand, glass factory’s quartz sand and refilling pressure sand. It is widely used for cleaning materials in the following industries: quarry, minerals, building materials, transportation, chemical industry, water conservancy and hydropower, cement mixture station etc.
