Limestone Roller Mill, Heavy Calcium Powder Processing Equipment, Kaolin Mill, Putty Powder Production Line
Description
Materials that can be processed by HVM vertical mill: ferrite, slag, slag, cement, diamond, iron ore, chrome ore, manganese ore, gold mine, copper mine, aluminum ore, lead zinc ore, tantalum niobium ore, polymetallic ore, nickel ore, bauxite, silicon carbide, titanium dioxide, talc, bentonite, calcite, kaolin, graphite, mica, wollastonite, feldspar, dolomite, pyrophyllite, quartz sand, fluorite, limestone, organic silicon, limestone Shale, volcanic ash, coal, etc.
The production line of a powder mill usually consists of a hammer crusher, a bucket elevator, a storage bin, a vibrating feeder, a micro powder mill host, a frequency conversion classifier, a dual cyclone dust collector, a pulse dust removal system, a high-pressure fan, an air compressor, an electrical control system, and so on. Large pieces of material are crushed by a hammer crusher into a feed particle size (about 1cm) suitable for the operation of ultrafine grinding machines. Then, the rotation speed of the grinding machine analysis machine is adjusted to achieve the required fineness for production. After manual packaging, bags can be formed, and automatic micro powder packaging machines and different models of grinding machines can be configured according to needs.

Re:The data based on Mohs'hardness 3-4 material
Limestone Bond Index≤13kwh/t
Performance advantages:
1. Efficient and energy-saving
When the fineness of the finished product and the power of the motor are the same, the output is more than twice that of the airflow mill, stirring mill, and ball mill.
2. Long service life of vulnerable parts
The grinding rollers and rings are forged with special materials, greatly improving their utilization. Generally, the service life can reach more than one year. When processing calcium carbonate and calcite, the service life can reach 2-5 years.
3. High safety and reliability
Due to the absence of rolling bearings and screws in the grinding chamber, there is no problem of bearings and their seals being easily damaged, and there is no problem of screws being easily loosened and damaging the machine.
4. Environmental protection and cleanliness
Using a pulse dust collector to capture dust and a silencer to reduce noise has the characteristics of environmental protection and cleanliness.
The structural composition of the limestone ultrafine grinding machine:
The main body of the limestone ultrafine grinding machine is composed of a host, a reducer, an analyzer, a fan, a bypass powder collector, a maintenance platform, and an electric control cabinet. The auxiliary equipment is composed of a jaw crusher, a bucket elevator, an electromagnetic vibration feeder, a storage bin, etc.
What precautions should be taken when working the limestone ultrafine grinder
1. Regularly check the bearing temperature. If the temperature is too high, check whether the lubrication and transmission parts are normal, and whether the rolling distance is too tight. Timely identify the cause, take corresponding measures, and shut down for inspection in severe cases.
2. Regularly check the tightness of the transmission belt. If the belt is too loose, it will reduce the transmission efficiency and affect the grinding effect. If it is too tight, it can easily cause bearing heating, increase power consumption, and reduce the service life of the transmission belt.
3. All transmission components must be tightened and reliable. Special tools should be used for disassembly or installation, and direct impact with tools such as hand hammers is prohibited.
4. Don't forget to check the pneumatic components. After the plastic mill is started, check the pneumatic components in the air circuit, the air circuit and the connection frequently for air leakage or damage. At the same time, check whether the air supply pressure meets the requirements. Check the use of the Timing belt frequently. If it is too tight, too loose, jumping, deviation, serious wear and other conditions are found, it should be adjusted, repaired or replaced in a timely manner.
Working principle:
The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing water are dried in the Contact process with hot gas to meet the required product moisture.
