La piel del rodillo del máquina de hacer briquetas de carbón es una parte importante de la máquina briquetadora. Está ubicado fuera del núcleo del rodillo de la máquina briquetadora.. Suele ser un componente cilíndrico con una rótula en su superficie.. La forma y el tamaño de estas rótulas se diseñan de acuerdo con el material prensado y la forma requerida del producto.. El ajuste de la piel del rodillo de la máquina de fabricación de briquetas Es un paso clave para garantizar el funcionamiento normal de la máquina briquetadora y mejorar la calidad del producto..

Ajuste del rodillo de la máquina briquetadora

1. Método de ajuste

Ajuste de espacio:

El espacio del revestimiento del rodillo determina la cantidad de llenado y la presión de moldeo del material.. El espacio adecuado puede garantizar que el material se distribuya uniformemente entre las pieles del rodillo y evitar problemas de moldeo causados ​​por una presión desigual..

El espacio entre las pieles de los rodillos generalmente se ajusta ajustando la tuerca de ajuste de la máquina.. El tamaño del espacio debe ajustarse según la naturaleza del material y los requisitos de moldeo..

En general, cuanto menor sea la brecha, cuanto más densas son las bolas moldeadas, pero un espacio demasiado pequeño puede provocar que el equipo se atasque o bloquee el material.; un espacio demasiado grande hará que la precisión del moldeo disminuya.

Verificación de paralelismo:

Utilice herramientas y equipos de medición para comprobar el paralelismo de los revestimientos de los rodillos y realice ajustes finos hasta que los dos revestimientos de los rodillos estén completamente paralelos en toda su longitud.. La garantía de paralelismo ayuda a que el material se esfuerce uniformemente entre las pieles de los rodillos y mejora la calidad del moldeo..

Ajuste de presión:

La presión de la máquina briquetadora generalmente se logra ajustando el cilindro hidráulico o el sistema de transmisión mecánica.. El tamaño de la presión debe ajustarse según la naturaleza del material y el efecto de moldeo.. Una presión demasiado baja dará como resultado una mala calidad esférica., mientras que una presión demasiado alta puede aumentar la carga del equipo y el consumo de energía., e incluso dañar la máquina.

High-pressure grinding rolls is mainly used in the ore industry and is also a type of crusher. As the main equipment for crushing in the ore industry, since it is the main equipment, it will be used very frequently. All machines are inseparable from daily maintenance and overhaul. Correct maintenance and overhaul can increase the service life of the machine, and early overhaul can detect problems early, so that small problems will not become bigger, affecting normal work and causing accidents.

Common fault inspection and repair of high-pressure grinding rolls

1. If the lubrication system finds that there is no grease overflow from the labyrinth seal of the bearing seat, the following reasons may be the case:

① lack of oil;

② pipeline failure;

③ grease pump is broken. If the color and properties of the oil flowing out of the oil drain port of the non-loaded bearing seat are found to have changed, it may be that cooling water or other foreign matter has been mixed into the lubricating grease.

2. The movable roller moves irregularly in the horizontal direction. En general, the nitrogen accumulator pressure is insufficient or damaged.

3. The hydraulic oil temperature is high. It may be: serious internal leakage in the system or the pump has been running for too long, and the hydraulic system needs to be checked.

4. The roller gap is too large. There may be the following reasons:

① Severe wear on the roller surface;

② No pressure;

③ There is material accumulation between the rollers. It needs to be handled as appropriate.

5. The roller gap is too small. It may be that there is a problem with the size of the gap block, or the position of the displacement sensor is set incorrectly.

6. The roller is stuck. It may be that there is foreign matter between the rollers, or there is too much material stored between the rollers when starting.

7. The roller does not rotate. The reasons include:

① Motor failure;

② Reducer failure.

8. The roller surface temperature is too high. It may be that the feed temperature is too high. Measures should be taken to control the upstream raw material temperature, otherwise it will affect the wear resistance of the roller surface and accelerate wear.

9. The bearing temperature is too high. The reasons include:

Both rodamientos de rodillos and ball bearings are rolling bearings used to reduce friction and support radial and axial loads in rotating applications. They differ significantly in several ways.

Difference Between Roller Bearings and Ball Bearings

1. Basic Definition and Structure

Roller bearing: It is a kind of rolling bearing and one of the widely used components in modern machinery. It relies on rolling contact between the main components to support the rotating parts. The rolling element of the roller bearing is usually cylindrical or conical, with different structural types, such as spherical roller bearings, thrust spherical roller bearings, tapered rollers and cylindrical roller bearings.

Ball bearing: It is also a kind of rolling bearing, and its rolling element is spherical, que es, the steel ball is installed between the inner and outer steel rings. The design of ball bearings enables it to withstand large loads and is widely used in various mechanical equipment.

2. Contact Mode and Load-bearing Capacity

Contact mode: The rolling element and raceway of the roller bearing are in line contact. As the load increases, the contact line will become a rectangle, and the contact area is relatively large. The rolling element and raceway of the ball bearing are in point contact. As the load increases, the contact point will become an elliptical area, and the contact area is small.

Load-bearing capacity: Due to the different contact areas, roller bearings usually have higher load-bearing capacity. Compared with ball bearings of the same size, roller bearings can withstand heavier loads, but the speed may be relatively low. Ball bearings are more suitable for low torque and high speed applications.

3. Application Characteristics

Roller bearings:

Applicable to occasions that need to withstand high radial and axial forces.

The starting torque is small, the rotation accuracy is high, and it is easy to select.
