LIMESTONE GRINDING MILL PRODUCTION LINE

Composition of limestone powder grinding mill production line

The mill production line usually includes a hammer crusher, bucket elevator, storage bin, vibrating feeder, micro-powder mill host, frequency conversion classifier, double cyclone powder collector, pulse dust removal system, high-pressure fan, air compressor, electrical control system, and other components.

Advantages of limestone grinding mill production line

Strong complete set:

The limestone grinding mill occupies a relatively small area and is highly systematic. It can form an independent production system from the rough processing of raw materials to the final material packaging.

Performance advantages:

1. High efficiency and energy saving
In the case of the same fineness of the finished product and the same motor power, the output is more than double that of jet mill, stirring mill, and ball mill.

2. High safety and reliability
There are no rolling bearings and no screws in the grinding cavity of the main machine of the limestone grinding mill, so there is no problem that the bearings and their seals are easily damaged, and there is no problem that the screws are easy to loosen and damage the machine.

3. Long service life of wearing parts
The grinding roller and grinding ring are forged with special materials, which greatly improves the utilization. Generally, it can reach more than one year, and the service life can reach 2-5 years when processing calcium carbonate and calcite.

4. Environmental protection and clean
The pulse dust collector is used to capture dust, and the muffler is used to reduce noise, which is environmentally friendly and clean.

5. Save labor cost
The electrical system adopts centralized control, and the grinding workshop of the limestone grinding machine can basically realize unmanned operation, saving labor costs, and ensuring the safety of the staff.

Price advantage:

SBM is an excellent manufacturer of mine milling equipment in China. All grinding mills are directly supplied by the factory and there is no middleman, so the cost performance is extremely high. In addition to ultra fine grinding mills, we can provide the configuration of the entire ore milling production line. All accessories, crushers, powder modifiers, etc., are directly supplied by the factory at affordable prices.

LIMESTONE ULTRAFINE GRINDING MILL

Structure of limestone grinding mill

The main part of the limestone powder grinding mill is composed of the main engine, the reducer, the analyzer, the fan, the bypass powder collector, the maintenance platform, and the electric control cabinet. The auxiliary machine part is composed of a jaw crusher, bucket elevator, electromagnetic vibrating feeder, storage bin, etc.

 

Working principle of limestone powder grinding mill

When working, the main motor drives the main shaft and the turntable to rotate through the reducer. The roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the ring raceway.

The bulk material is crushed into small particles by the hammer crusher and then sent to the storage bin by elevator. Then through the vibrating feeder and the inclined feeding pipe, the materials are evenly sent to the bulk tray on the upper part of the turntable.

The material is scattered to the periphery of the circle under the action of centrifugal force. And fall into the raceway of the grinding ring, and then be impacted, rolled, and ground by the ring roller.

The material is processed into powder through the three-layer loop. The high-pressure fan sucks external air into the machine through suction and brings the crushed materials into the powder concentrator.

The rotating impeller in the classifier makes the coarse powder fall back and regrind. The fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged by the discharge valve. The airflow with a small amount of fine dust passes through the pulse dust collector and is discharged through a fan and a muffler.
