As ring roller mill technology becomes increasingly mature, many calcium carbonate powder enterprise customers have discovered that ring roller mills have more obvious technical advantages compared with other grinding equipment when grinding calcium carbonate. Therefore, more and more calcium carbonate companies choose ring roller mills as the grinding equipment for calcium carbonate raw materials. It is understood that in the newly built modern calcium carbonate production lines, more than 90% of calcium carbonate companies use ring roller mills as grinding equipment for marble, calcite, limestone, etc., and more and more companies use ring roller mills to grind calcium carbonate raw materials. many. Especially after HCM Machinery’s HCH1395 series ultra-fine ring roller mill won the award for the most energy-saving and consumption-reducing technology and equipment for calcium carbonate production at the Calcium Carbonate Annual Conference, the ring roller mill has become one of the important equipment for modern calcium carbonate production.

HCH ultra-fine ring roller mill is a newly developed ultra-fine grinding equipment successfully developed by HCM Machinery based on many years of production and R&D experience. This machine has comprehensive mechanical crushing properties such as rolling, grinding, and impact, and is widely used in talc, calcite, calcium carbonate, dolomite, potassium feldspar, bentonite, kaolin, graphite, carbon, etc. with Mohs hardness below level 7 and humidity Ultra-fine crushing of various non-metallic minerals within 6%. It is a truly efficient, energy-saving ultra-fine crushing equipment especially suitable for deep processing of non-metallic minerals.

HCH ring roller ultrafine mill consists of main machine, classifier, blower, belt feeder, storage hopper, pipeline system, pulse dust collection system, transmission system, electric control cabinet, etc.

Pulverizing system process flow: The materials are broken into materials smaller than 10mm by the jaw crusher, lifted to the storage hopper by the bucket elevator, and then quantitatively sent to the main machine cavity by the feeder for grinding. The material undergoes multi-layer crushing and grinding in the main machine cavity. The ground powder falls to the chassis due to gravity, and is blown to the classifier above the main machine for sieving under the action of the air flow of the blower. Those whose fineness is too coarse will still fall into the main machine for re-grinding, while those whose fineness meets the specification will flow into the pulse dust collector with the wind. After collection, the finished product is discharged through the discharge valve. The purified air flows into the blower through the residual air duct above the pulse dust collector. The air path is circulating. Except for the positive pressure from the blower to the grinding chamber, the air flow in the other pipelines flows under negative pressure. There is no dust leakage, and the workshop is basically guaranteed to be dust-free.

HCH ultra-fine ring roller mill has four obvious advantages:

Reliable operation

1. Large crushing ratio and high energy utilization. Non-metallic mineral particles with a feed particle size of <15 mm can be processed into micro powder of <10 μm at one time (under the standard of 97% pass rate), and -3 μm fine powder accounts for about 40%, with a large specific surface area. It has the advantages of high efficiency and low consumption of powder produced by high-speed impact crusher, and has a product fineness close to that of airflow mill.

2. HCH1395 ultra-fine ring roller mill is currently a very large ultra-fine ring roller mill in China, with a capacity of up to 11t/h, breaking the pattern that ring roller mills cannot carry out large-scale production.

3. More environmentally friendly and energy-saving. It is produced under negative pressure and equipped with a high-efficiency and enlarged dust collector, so the working environment is less dusty. It adopts semi-automatic control and unique technology to greatly improve production efficiency. It is currently a fine grinding equipment with low energy consumption.

High cost performance

1. Stable operation, the main machine is equipped with a built-in grading mechanism, the grading wheel structure is unique, the grading effect is good, the product particle size is good, there is no large particle pollution, and the product quality is stable. It is an ideal equipment for the current dry production of non-metallic mineral fine powder.

2. The grinding wheel and grinding ring are made of special wear-resistant steel, which has low wear and long service life, reduces the frequency of shutdown, maintenance and replacement, and is easy to maintain.

3. The host base adopts an integral casting structure, which not only ensures structural strength but also eliminates

It has good vibration performance, small vibration and smooth operation.

High efficiency and high productivity

1. The equipment can form an independent and complete production system from the crushing, transportation, and milling of raw materials to the collection, storage, and packaging of finished products, which is highly systematic.

2. The main machine has a built-in grading system to adjust the product fineness as needed. It can produce both fine powder with D97=3-8μm and ordinary powder with D97=10-40μm. The equipment has strong applicability.

Wide applicability

1. The grinding mill has a three-dimensional structure and occupies a small area, which greatly reduces the cost of factory land and infrastructure, and the investment cost is low;

2. The product is used for ultra-fine crushing processing, is highly efficient and energy-saving, and the equipment’s own investment cost is low, economical and affordable, and the investment returns are fast.
