Experts from Hongxing Machinery remind you that product quality must be taken into consideration.

The grinding rod mill drives the cylinder in rotation by the engine through the rotation of the reducer and big gears around with the deceleration or through low speed synchronous motor driving directly peripheral big gears. The grinding rod mill is equipped with appropriate grinding medium-steel bar, which is raised to a certain height under the centrifugal force and friction force and then cast down or discharged. The to-be-crushed materials are continuously added to the cylinder, shattered by the rotating grinding medium and discharged to the next procedure by the overflow and the power of continuously feeding in materials.

Drying is achieved as hot gas passes through the pulverizer and removes moisture from the pulverized coal. The hot gases used should have a low oxygen content, this reduces the likelihood of accidental combustion within the mill. It is possible for hot gases to be taken directly from the furnace exhaust manifold, providing safety interlocks and valves are used.

Grinding is achieved using the impact, crush or attrition methods (see below). Grinding increases the cross sectional area of the coal and allows it to dry quicker whilst also making it easier to ignite. Grinding is often referred to as 'size reduction'.

Classifying occurs in order that pulverized coal reaches the desired fineness prior to entering the furnace. Larger particles are returned to the grinding area where they are further reduced in size until they are small enough to pass through the classifier.

Coal pulverizers increase the cross-sectional area and dryness fraction of coal prior to it entering a furnace. Pulverized coal ignites more efficiently than raw lumps of coal, thus the overall efficiency of the furnace increases if it is fired on pulverized coal. Coal pulverizers are used extensively within industries that operate coal fired furnaces, this includes the power generation and steel industries.

Raw coal (sometimes pre-treated) is fed into the centre of the grinding table. The grinding table rotates which causes the coal to move towards the outer periphery of the grinding table. The coal is ground between the rollers and grinding table. When enough coal has been reduced in size, it will flow over the top of the dam ring (retention ring).

Louvres (nozzle ring) around the outer perimeter of the grinding table allow hot gas to flow into the grinding mill through the mill base. Some of the pulverized coal is transported from the base of the mill up to the classifier by the hot gas stream i.e. the coal is transported pneumatically. Regulating the amount of gas that passes through the nozzle ring also regulates the amount of pulverized coal that is delivered to the furnace.

Oversized pulverized coal impacts with the rotating classifier and drops back onto the grinding table for further grinding. Correctly sized coal particles pass through the classifier and exit the mill through the discharge duct. Pulverized coal that has passed through the classifier is pneumatically conveyed to the furnace.

Another defining factor for pulverizers is their operational speed. Pulverizers are split into low, medium and high speed groups. The type of grinding method employed is usually linked to the pulverizers operational speed:

long-lasting coal mill for efficient grinding | flsmidth

long-lasting coal mill for efficient grinding | flsmidth

Our ATOX Coal Mill is a compact vertical roller mill that can grind almost any type of raw coal. The coal mill utilises compression and shear force generated between the large rollers and the rotating table to crush and grind raw coal, removing the need for a separate piece of equipment for crushing. The coal mill can also grind petroleum coke and anthracite down to a fineness below 5% +90 micromillimeters (mm) when coupled with a variable speed mill motor.

As the feed material is added to the mill, the moisture evaporates almost immediately. A continuous gas stream from the nozzle carries the finer particles to the separator, where they will be assessed for the specified fineness. For safety reasons, the coal mill is designed with no external recirculation of materials. Material is prevented from spilling over the edge of the dam ring as both the dam ring height and grinding pressure are adjustable.

The ATOX Coal Mills efficient separator allows material that has reached the required fineness to leave the grinding mill and sends oversized material back for further grinding. The fineness is controlled by adjusting the rotor speed. The high efficiency of the separator is due to the rotor being equipped with an outer ring of louvre plates that are hardfaced for longevity.

The durable grinding mill can handle virtually any type of raw coal and has been designed to grind feed materials with varying moisture levels. The ATOX Coal Mill handles feed materials with less than one percent moisture and up to 25 percent moisture, where abrasiveness and stickiness is not an issue for grinding.

The materials used to produce the ATOX Coal Mills segmented wear surfaces are durable and therefore, last longer. The reversal of liner segment option maximises use of these hard surfaces, making sure every surface is exploited while helping to address uneven wear at the same time.

The separator, with the highest mill capacity, ensures high separation efficiency through having a low bypass to reject. An efficient separator leads to a number of benefits including low specific power consumption for the mill motor, low vibrations, energy savings due to minimal pressure loss, and optimised airflow.

Long-lasting durability is extended to the separator where the inside of the reject cone and outlet top section are faced with Densit. The wear plates for the louvres are also hardfaced to maximise wear life.

The ATOX Coal Mills equipment is located at or above floor level for easy maintenance and cleaning. There are easy-access doors for inspection and maintenance of all of its parts, where roller replacement can occur while still inside the mill. For comprehensive maintenance, the large door is removable for crane access.

Our coal mill offers the flexibility of non-inert and inert operation, depending on the exploding potential of your coal type. The tailored layout considers your coal grinding needs, ensuring simple and optimised operation. For example, the availability of heat sources to dry raw coal helps determine the final layout.

Liner segments can be reversed so that the wear, which normally occurs on the outer edge, can be spread evenly, making use of the entire segment surface. The coal mills liner segments can also be repeatedly hardfaced for maximal longevity.

The heated rotary feed sluice ensures uniform flow of feed into the ATOX Coal Mill for optimum mill operation including minimising power consumption. It is the right solution for a sticky feed material as hot gas from the mill inlet is guided through the rotor, preventing the sticky
