What types of ore grinding machines are there?

Guilin Hongcheng, a well-known Ore grinding machine manufacturer, produces various ore mills with various finenesses. There are traditional Raymond mills (80~325 mesh ore powder), upgraded version of  Raymond mill called pendulum mills(80~600 mesh), ultrafine ring roller mills (80~1250 mesh), vertical mills and superfine vertical mills. The powder fineness ranges largely from 80 to 2500 mesh. The operation of the mill equipment is stable, environmentally friendly and energy-saving.

The selection of the ore mill depends on the fineness and capacity of the ore powder. A Raymond mill is usually chosen for producing about 20 tons the ore powder of a single machine with a fineness of 80-325 mesh. An energy-saving and high-producing vertical mill can be selected for an output of a single machine of more than 40 tons ore powder with a fineness of more than 325 mesh. And the ultra-fine vertical mill can be chosen for a  600-mesh ore powder of about 25 tons of a single machine. Definitely, it is also necessary to choose the model according to your investment needs. There are small, medium and large models of mills, which can be selected according to the financial situation.

The price of the mill depends on the types and the configured production line components. Guilin Hongcheng can customize the whole process for you with rich experience, providing a strong guarantee for your start-up and profit if you need EPC general contracting for the construction project of the ore pulverizer production line,

1. The use of ore powder

How much is a ton of ore powder? The price of non-metallic ore powder with different fineness is various. For the same ore, the finer the powder, the higher the price. Why should buy an ore mill production line to produce ore powder?

Ore powder can be used in daily necessities, building materials, ceramics, glass and refractory materials, chemical industry, agriculture, environmental protection, energy saving and other fields. Therefore, many powder factories purchase suitable ore mills for their needs to make ore powder and sell them.

2. Production process of ore mill: detailed explanation of process of producing ore powder 

The first stage: The crushed large ore is transported to the raw material warehouse by a special vehicle, and then the material is sent to the jaw crusher by a forklift/person for crushing til it is smaller than the feed size of the mill

The second stage: the crushed ore is lifted to the storage hopper by the elevator, The material is discharged from the storage hopper and then fed to the main machine evenly by the feeder

The third stage: After grinding process, the qualified products are screened by the screening system and enter the collector through the pipeline. After collection, they are discharged through the discharge valve and become finished products, While the unqualified products fall into the main machine for re-grinding

The fourth stage: the airflow after the purification of the finished product flows into the blower through the residual air pipe above the dust collector. The air path is circular. Except for the positive pressure from the blower to the grinding chamber, the airflow in the other pipelines flows under negative pressure. The indoor sanitation is in good condition
