Product Models & Basic Production Capacity Advantages

Our company has launched four models of CJM-800, CJM-1000, CJM-1250 and CJM-13800 for anode materials to meet the diversified production demands of different customers.

1. Configuration of Flagship Model The flagship CJM-1380 model adopts patented technical solution of double classification, double dust removal and double fans, with a high hourly output of 1.2~1.4 tons and stable powder fineness.
2. Improved Production Capacity under Identical Working Conditions Under identical production conditions of raw material type, fineness standard and equipment model, the production capacity of our equipment is over 15% higher than that of traditional equipment. Compared with single-layer impact mills, all double-layer impact mills can increase output by 10%~20% with the same raw materials and fineness requirements.

Integrated Crushing & Shaping to Greatly Reduce Comprehensive Production Costs

In the production of many finished anode material products, crushing and shaping are two separate processes. Independent shaping procedures require extra investment in shaping equipment, factory land and plant space, as well as additional power consumption, labor operation and maintenance costs.

Our equipment realizes one-step forming of crushing and shaping, eliminating the full set of supporting investments for independent shaping, and cutting comprehensive production costs from multiple dimensions including equipment, plant space, energy consumption and labor.

Supporting cost-benefit data for verification: For every 1% increase in finished product yield, the production cost per ton of product can be reduced by 100 RMB; a 2% yield increase saves 200 RMB per ton, and a 3% yield increase saves 300 RMB per ton. When power consumption is reduced by 5%, the electricity cost per ton drops by 15 RMB; for power consumption reductions of 10%, 15% and 20%, the electricity cost per ton decreases by 30 RMB, 45 RMB and 60 RMB respectively.

Core Crushing Structure & Working Principle of Double-Layer Impact Mill

(I) Patented Double-Layer Crushing Chamber Structure

The core crushing unit of the equipment includes a complete set of patented structures: main machine inner cavity, crushing rotor, gear ring, feeding and discharging channels, material throwing disc, main shaft, hammer disc, upper hammer head and lower hammer head. It relies on double-layer hammer heads for composite crushing to achieve performance breakthroughs.

1. Coordinated Division of Labor for Upper and Lower Hammer Heads ① Upper hammer head: Mainly responsible for coarse crushing of materials and depolymerization of powder; ② Lower hammer head: Agitates materials inside the chamber, strengthens mutual collision and friction between particles, and synchronously completes fine crushing and powder shaping to optimize the morphology of finished powder; ③ Linkage effect of double-layer hammer heads: When upper and lower hammer heads work simultaneously, the equipment’s crushing space is increased by more than 3 times compared with single-layer mills, achieving higher production capacity and lower unit power consumption.
2. Auxiliary Crushing and Shaping Functions of Material Throwing Disc ① Flow guiding function: Guided by the centrifugal force of the crushing rotor and the self-weight of materials, raw materials flow rapidly downward into the crushing area; ② Filling and friction function: The surface area of the material throwing disc is larger than that of the crushing hammer disc, which enables materials to evenly fill the circumference of the crushing rotor. Particles fully collide, extrude and rub against each other to complete efficient crushing and powder shaping simultaneously; ③ Uniform discharging function: Driven by centrifugal force, crushed and shaped powder is evenly thrown outwards to the circumference of the chamber for subsequent classification and collection.

(II) Core Structural Differences Between Double-Layer Mill and Single-Layer Impact Mill

1. Greatly Expanded Crushing Space The gear ring height of the double-layer impact mill is about 1.5 times higher than that of single-layer mechanical mills, the crushing gap is expanded by about 2 times, and the overall crushing space is increased by more than 3 times.
2. Composite Crushing Force (Dual Crushing of Impact and Friction) Single-layer mechanical mills only rely on end-face crushing, completing crushing mainly through the impact force generated when powder hits hammer heads and gear rings. The double-layer impact mill integrates impact force from end-face crushing + friction force from circumferential crushing. Powder particles not only collide with hammer heads and gear rings at high speed, but also generate strong friction in the gaps between hammer heads and gear rings. The mutual friction and extrusion between powder particles deliver higher crushing efficiency and superior sphericity and morphology of powder.

Advantages of Double-Layer Impact Mill in Powder Performance

A core production requirement in the anode material industry is a narrow particle size distribution of powder. Through innovative matching of the crushing chamber, classification system, cyclone collection and fan system, as well as optimized feeding, control and post-processing systems, our double-layer impact mill supports stable automatic 24-hour continuous production with outstanding powder indicators:

1. Excellent particle size indicators: Finer Dv50 of finished products, narrower particle size ranges of D10, D99 and D100, and concentrated particle size distribution;
2. Superior powder morphology: The equipment comes with built-in shaping effect. The finished powder features regular particle shape, excellent bulk density and tap density, low fine powder content and high finished product yield. It can be directly used as an integrated crushing and shaping machine for many types of anode raw materials.

All-Round Competitive Advantages of Double-Layer Impact Mill in the Anode Material Industry

(I) Production Capacity Advantage

With identical raw materials and fineness standards, the output is 10%~20% higher than that of single-layer impact mills. The flagship CJM-1380 model delivers an hourly output of 1.2~1.4 tons.

(II) Finished Powder Quality Advantage

Powder particles feature regular morphology, low fine powder content, high tap density and high finished product yield. The integrated crushing and shaping process eliminates independent shaping procedures.

(III) Operation & Maintenance Cost Advantage for Wear Parts

Wear parts of the equipment adopt a composite wear-resistant protection scheme (Attached Drawing: Full Ceramic Protection Logo): The surface of the hammer disc is equipped with a wear-resistant welding protective layer, and the striking surface of hammer heads is fully protected by hard alloy. The service life of wear parts is greatly extended, cutting the comprehensive service cost of wear parts by nearly 50%. Key components in contact with materials are made of ceramic and composite stabilized zirconia materials to eliminate metal contamination of powder.

(IV) Built-In Drying Function to Reduce Raw Material Pretreatment Costs

The large crushing chamber and strong powder friction of the equipment generate higher internal operating temperature of the cavity, accelerating the evaporation of internal moisture in raw materials. It supports continuous production of raw materials with different moisture contents without blockage during the whole process. Independent front-end drying equipment can be eliminated, reducing drying costs by 30~60 RMB per ton of product.

(V) Wide Range of Raw Material Adaptability

It is well suited for mass production of powder with various fineness levels, targeting mainstream anode raw materials such as petroleum coke and coal-based needle coke.

Energy Saving & Consumption Reduction Advantages of the Whole Equipment

1. The crushing space of the chamber is increased by 30%, and the power consumption per unit product of the whole machine is reduced by 10%~30%;
2. The double-layer composite crushing structure cuts invalid energy consumption, resulting in significantly lower power consumption under the same output compared with single-layer impact mills;
3. The integrated crushing and shaping process eliminates dual energy input from independent shaping and drying equipment, greatly lowering comprehensive electricity costs.
