LYH996 Series New Type Intelligent Vertical Ring Roller Mill

LYH996 series Ring Roller Mills consists of a variable frequency screw feeder, main machine, fan, classifier, hydraulic system, pulse dust collector, electrical control device, and pipeline system. The main machine consists of upper and lower machine bodies, a grinding roller, a rotary grinding disc, and a reducer. During operation, the material enters the main machine quantitatively, evenly, and continuously through the variable frequency screw feeder on the upper side of the main machine. Under the centrifugal force of the rapidly rotating grinding disc, the material is thrown to the inner wall of the grinding disc, and the material is brought between the grinding roller and the grinding ring and is rolled and crushed under the pressure of the oil cylinder outside the grinding roller. At the same time, the high-pressure and high-flow airflow generated by the air supply system is mixed with the crushed powder to form a high-concentration airflow, which enters the classifier on the main machine for sorting. The coarse powder that does not reach the fineness falls back into the grinding disc for re-grinding, and the qualified fine powder is collected in the finished product collector with the airflow, discharged from the discharge port of the finished product collector, and then stored in the finished product warehouse through the lifting equipment.

1. There is a gap of 3-5mm between the grinding roller and the grinding ring. The roller and the ring never come into direct contact, and the roller and the ring wear less, so the ground material has low iron content and does not turn white;

2. Hydraulic pressurization is adopted, and the loading force of the grinding roller can be freely adjusted, which can adapt to the grinding of various materials. Hydraulic springs are set in the hydraulic system, which can run smoothly and reliably and is easy to maintain;

3. New technology and new wear-resistant materials are adopted, and the life of wearing parts is long. The service life of grinding rollers and grinding rings for materials such as heavy calcium is up to 6-8 years;

4. The finished product particle size is 400-1500 mesh;

5. High output and low energy consumption. The output of processing 1250 mesh calcium carbonate is as high as 1.5 tons/hour. Compared with ball mills and other models, the power consumption can be reduced by about 30%;

6. The equipment has low noise during operation, the system is operated under negative pressure, and a pulse dust collector is used. The dust meets the standard and there is no noise and dust pollution.

Ring Roller Mills are often used as complementary equipment in material processing lines, particularly in conjunction with crushing or grinding machines. Their primary purpose is to produce fine, uniform powders from various materials, including minerals, chemicals, and ceramics. They are especially effective in reducing particle size after initial crushing or grinding processes.

1. Crusher + ring roller mill:

Applicable materials: Materials with high hardness and large particle size, such as ore, limestone, etc.

Working principle: The crusher initially breaks large pieces of material into small pieces, and then sends them to the ring roller mill for fine grinding.

Advantages: Clear division of labor, improved crushing efficiency, and extended the service life of the ring roller mill.

2. Screening machine + ring roller mill:

Applicable materials: Materials that need to be graded.

Working principle: After the material is crushed by the ring roller mill, it is graded by the screening machine to obtain products of different particle sizes.

Advantages: Improve product purity and meet different particle size requirements.

3. Dust collector + ring roller mill:

Applicable materials: Materials with more dust.

Working principle: The dust generated by the ring roller mill is processed by the dust collector to reduce environmental pollution.

Advantages: Improve the working environment and improve product quality.

4. Conveying equipment + ring roller mill:

Applicable materials: Materials that need to be processed continuously.

Working principle: The conveying equipment continuously feeds the materials into the roller mill for crushing.

Advantages: Realize automated production and improve production efficiency.

5. multi-stage classifier + ring roller mill:

Combination and Working Principle

Grinding: The material is fed into the ring roller mill, where it is ground into a fine powder.

Classification: The ground material is then fed into the first stage of the multi-stage classifier. The coarser particles are retained in this stage, while the finer particles pass through to the next stage.

Multiple Stages: This process continues through multiple stages, with each stage producing a different particle size fraction. The final stage typically produces the finest particles.

Ring Roller Mill is widely used in mining, building materials, the chemical industry, metallurgy, and other industries, mainly used for:

Mineral processing: crushing limestone, calcite, barite, and other minerals, preparing various fillers.

Building materials industry: raw materials for producing cement, ceramics, glass,s and other products.

Chemical industry: crushing various chemical raw materials, such as pigments, dyes, etc.

Metallurgy industry: crushing slag and preparing metallurgical auxiliary materials.

Other industries: food, medicine,e and other industries can also use ring roller mills for material crushing.
