Rice Husk Ultrafine Pulverizer

As a reliable supplier of Rice Husk Ultrafine Pulverizer, Xingshengwei, with years of mechanical manufacturing experience, conducts wear-resistant and strengthened design for the core components of the equipment. This rice husk ultrafine grinder adopts a fully enclosed negative pressure operation system, which takes into account both high production capacity and environmental protection requirements. It can be customized with different production capacity models according to customer needs, and is widely applicable to scenarios such as rice mills and biomass energy enterprises, achieving efficient recovery and secondary utilization of rice husk resources.

Rice Husk Ultrafine Pulverizer adopts the two-stage pulverization principle of "coarse pulverization + ultrafine grinding", and is combined with the air selection and classification system to complete the efficient pulverization operation.

Firstly, the rice husk raw materials are uniformly fed into the crushing chamber through a variable-frequency screw feeding device to prevent the light rice husks from being blocked by "bridging". The high-speed rotating hammer head initially strikes the rice husks to break them. The crushed materials, under the action of centrifugal force, undergo intense shearing and collision with the wear-resistant gear ring. Subsequently, the airflow carries the crushed materials into the classification chamber. Under the balanced action of the centrifugal force of the high-speed classification wheel and the buoyancy of the airflow, the fine powder that meets the fineness requirements is sent to the dust collection device for collection, while the coarse powder that does not meet the standards is returned to the crushing chamber for re-grinding until the particle size standard is met.

The entire process is accomplished through negative pressure air circulation, achieving an integrated completion of crushing, classification and conveying, ensuring uniform particle size of the finished product and no dust leakage.

Controllable fineness: Equipped with a variable frequency classification motor, the fineness of the 80-400 mesh finished product can be precisely adjusted, meeting the differentiated requirements of different application scenarios for the particle size of rice husk powder, with high classification accuracy and no large particle impurities.

4. Environmental protection and safety: Fully enclosed negative pressure operation combined with a pulse bag dust collection system ensures a dust collection rate of over 99%, eliminating dust pollution in the workshop; equipped with an inspection door and a rotor interlock protection device, as well as a real-time monitoring device for bearing temperature, eliminating potential safety hazards from the source.

5. Convenient operation: Modular structure design, with 180° symmetrical double inspection doors facilitating quick replacement of parts, reducing downtime for maintenance; intelligent electrical control system integrates overload alarm, start-stop protection functions, allowing beginners to operate easily.

Characteristics and Application Scenarios of Rice Husk Ultrafine Pulverizer

Core features

The rice husk ultrafine pulverizer is specifically designed to solve the pulverization problems of hard texture and dense fibers of rice husks. It features a wide feeding range (≤15mm), adaptability to high moisture content of materials (≤6%), and no temperature rise during the pulverization process. It can be adapted to the processing of heat-sensitive materials. It also has the function of particle shaping, which can increase the bulk density of rice husk powder and facilitate subsequent storage and transportation. The overall structure of the equipment is compact, occupying a small area. It does not require additional air compressors or conveying pipelines. It can be put into operation simply by connecting water and electricity.

Application scenarios

Feed processing: Grind rice husks into fine powder of 80-120 mesh and use it as a feed additive for livestock and poultry to increase the fiber content of the feed and improve the digestion and absorption effect.

Biomass energy: 100-150 mesh rice husk powder can be pressed into biomass pellet fuel, with a calorific value of 3500-4000 kcal/kg, which can replace traditional coal for heating and power generation in boilers and power plants.

Organic fertilizer and planting: Mix rice husk powder with livestock and poultry manure for composting to enhance the air permeability of the compost and promote fermentation. After carbonization, it can be used as a seedling substrate or soil conditioner to enhance the soil's water retention and aeration performance.

Industrial processing: Ultrafine rice husk powder with a mesh size of over 200 can be used to produce insulation materials, lightweight bricks, rubber reinforcing agents, or to extract silica (white carbon black) for use in industries such as coatings and tires.

Environmentally friendly materials: After being processed into ultrafine powder, they can be used as raw materials for degradable disposable tableware and packaging materials, which is in line with the national green environmental protection policy requirements.

FAQ

Q1: Is the Rice Husk Ultrafine Pulverizer suitable for processing rice husks with high moisture content?

A: The equipment can handle rice husk raw materials with a moisture content of no more than 6%. If the moisture content of the raw materials is too high, it is recommended to carry out drying treatment first to avoid the situation of material adhesion and blockage of the crushing chamber, which will affect the crushing efficiency and the quality of the finished product.

Q2: What scale of enterprises are suitable for different models of equipment?

A: The XSW-300 model is suitable for small rice mills and family workshops (with an output of 10-50kg per hour). The XSW-500 and XSW-750 models are suitable for medium-sized processing plants (with an hourly output of 50-1000kg). The XSW-950 model is suitable for large-scale biomass energy enterprises and large-scale processing plants (with an hourly production capacity of 500-1500kg). Non-standard models can also be customized according to the actual production capacity requirements of customers.

Q3: Is there a lot of noise during the operation of the equipment? Is daily maintenance complicated?

A: The equipment is equipped with a composite sound insulation cover, with operating noise ≤75dB, meeting the noise standards for industrial production. Daily maintenance is simple, mainly including regular inspection of the wear of hammer heads and liners, timely replacement of lubricating oil, and cleaning of dust removal filter bags. Under normal maintenance, it can ensure the long-term stable operation of the equipment.

Q4: How long is the warranty period?

A: The entire equipment is guaranteed for one year, and lifetime technical support is provided.

Q5: Can the fineness of the finished product of the rice husk ultrafine grinder be customized?

A: The standard fineness of the finished product is 80-400 mesh. If the customer has a higher fineness requirement (such as over 400 mesh), please communicate in advance. We will achieve customization by optimizing the structure of the grading wheel and adjusting the equipment parameters, etc., to meet the special processing requirements.
