The New Research about Crusher Sealing

With mechanized mining of coal resources, coal is pulverized as well as share from the end of your column increases. When using the chase also in the coal washing plant to form slime and coking coal washing practice increased flotation tailings. Both as increasing numbers of slime from coal by-products. As being the slime features a fine grain size, water holding strong, high ash content and contain more clay, etc., for that using slurry inconvenience, almost all the washing plant sludge is sold to local farmers. First, polluting the environment, but in addition wasteful of resources small scale gold mining plant。

Crusher sealing belongs to one of the basic mechanical components of crusher with a complex precision structure, it is also the key components of many kinds of pumps, reaction kettle, turbo compressor, submersible motor and other equipments. The sealing performance and service life depends on many factors, such as the model selection, the accuracy of the machine, the correct installation and use.

According to the different working conditions and dielectric properties of mechanical seal, the crusher sealing can be classified into high temperature resistance and low temperature resistance crusher sealings, high pressure resistance and corrosion resistance mechanical sealings, granular media adaptation crusher sealings and easy vaporization of light hydrocarbon medium mechanical seal. We should according to different use select different structure model material mechanical seal.

The main parameters of the model selection include: seal chamber pressure ( MPa ), the fluid temperature ( c ), working speed ( M / s ), the characteristics of the fluid and the effective space of installing sealings. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery ,like flotation cell, Henan Hongxing is always doing the best in products and service.

The basic principles for the model selection:

1. According to the chamber pressure of the sealings to define the seal structure use balanced or unbalanced type, single face or double end.

2. According to the working speed to determine the sealings use rotating type or stationary type, hydrodynamic or non contact type.

3. According to the temperature and fluid properties to determine the friction secondary seal material and correctly choose the lubrication, cleaning, heat insulation and cooling of the mechanical seal circulation protection system.

4. According to the effective space of installing sealings to determine use the multi springs or a single spring or wave spring, internal type or external type.

Crusher blocking material is mainly due to stop jumping the crusher cavity volume under the rownot too much material, to withstand dynamic cone, resulting in motor overload stop jumping.Usually caused by two circumstances stop jumping: the first is the high yield crusher, conveyorplate away too late; the second stop jumping the downstream equipment, crushing machine to break.This situation occurs for a volume, the material to crushing cavity can continue to turn out all the reasons, time-consuming, generally at least every 3 to 4 hours to complete.

Crusher to resolve the issue of blocking materials, can be solved, not only can reduce the laborburden of the workers, also increased the production efficiency of crushing machine, crusher ShideThis access has enabled effective working correctly, thus reducing maintenance time, increasedeconomic efficiency .
