A brief description: B series universal pulverizer

Two days ago, Gong Aimei's right hand into pulverizer in critical condition, thanks to "119" Fire fighters arrived in time cut the pulverizer for the four fingers pinch-off to win the success of continued access of time.

April 5 at 7 pm, martial arts, who lives in the town of Camp County on the popularity of the village of Gong Aimei and her husband, together with relatives to borrow one of the pulverizer to pulverze reared Pig feed, one inattentive, Aimei Gong to the machine fill the right hand was suddenly click into volumes, intense pain sent her screaming at the same time, the machine's own protection also played a role in switching, automatic cut off power supply, pulverizer stopped, this did not his right hand caused further harm. Panic, the husband Geng Mingkui immediately dial the "110", "119", "120" alarm call. Less than 10 minutes, Wugong County Fire Squadron on three fire fighters rushed to the scene, because of bleeding, his wife was issued a faint groan. Fire fighters at the scene in view the End of the opinion that the pulverizer to spend too much time, in order to promptly rescued his wife, they immediately used the exclusive use of cutting equipment for the pulverizer to carry out destructive cutting, just as soon as possible to remove his wife's hand. Less than half an hour about the whole process, the right hand arch Aimei finally separating from the pulverizer, but one of four fingers had been pinch-off, leaving the thumb is also a serious injury.

In the cement production process, the grinding (cement and slag) power consumption accounted for Integrated Product power consumption over 60%, especially the slag powder 400m2/kg than in the above table, the grinding power consumption remained at 90kwh / t more than hard slag cement mill grinding of a direct impact on the grinding capacity.

With China's sustained economic development, China's iron and steel industry has been rapid development in 2004 China's steel output reached a record high for the 272 million tons, becoming the world's first iron and steel power. After the rapid development in recent years, iron and steel industry is gradually showing insufficient natural resources, tons of production of excessive energy consumption, environmental pollution and other conflicts. Scrap iron and steel industry resources as a "second mining", with energy conservation, reducing pollution, protecting the environment, recycling, etc., and its impact will be bigger and bigger. In recent years, the supply of scrap steel each year in the rise, its role gradually expanded to break through 50 million tons in 2004, so that resources will be further recycled.

Mainly from the domestic steel scrap recycling in social institutions, their social recovery of scrap steel scrap accounted for about 60%, which is the main source of scrap steel in China; followed by the steel mills produce steel scrap; another Although China has become the first production of steel big country, but China's reserves of iron and steel in general is not very adequate, so the total amount of domestic steel scrap was also unable to meet the demand for steel on steel scrap, about 1 / 4 the volume rely on imports to make up for the domestic steel scrap resources. EAF is a major consumer of steel scrap resources major, but with the EAF in the steel industry to further expand, the demand for steel scrap resources will also be further expanded.

The pulverizer is constructed solely for the pulverization or reduction to dust of sand, gravel, or the small work of stamping machines, and cannot be used itself as a crusher or breaker. It consists of four parts or elements, all of which are necessary to its use. The first is an automatic feeding-mill, which furnishes a regular and constant supply of the material to be pulverized.

The second element is an iron drum or cylinder, containing an air-wheel, which converts the sand or gravel into dust by the action of rotary currents of air , created by the wheel. No air enters or escapes from this cylinder, unless by the aid of other machinery. The material can be retained in the cylinder until it is completely reduced.

Pulverizer

The pulverizer that we offer works on the principle of powdering and grinding materials in-between fixed serrated plates and rotary swing beaters fixed on a dynamically balanced rotor. We provide a perforated sheet at the bottom of the grinding chamber, which control the required product fineness.

Micro Pulverizers

VM Micro Pulverizers, conventional in design, Has its own advantages for various applications. A built-in water circulation jacket retains grinding temperature lower than otherwise. Design provides for admitting extra air during grinding to facilitate cool operation. Soft to medium hard materials are quickly pulverized to fine powder. Improved mixing and dispersion are added advantages of such mills. Quite popularly, it is also called High Speed close tolerance Hammer Mill.

The Micro Mill provides higher production at low cost. Quite popularly, it is also called high speed closed tolerance Hammer Mill.

It's low temperature rise during grinding is particularly advantageous in the handling of heat sensitive materials.

The coal pulverzing system in a fossil power plant is considered the final stage of the fuel supply. Pulverizing equipment reduces the coal to the required fineness before it enters the boiler furnace. Different types of pulverizing units are used for reducing the coal to the required fineness, such as:

(1) The "impact mill” which hammers the coal in to fine particles by means of hammers mounted on a rotating shaft.

Direct fired systems have exhibited half the explosion frequency of bin storage systems. Because flue gas is used as the pneumatic transport medium in bin storage systems, the plants may assume an inert gas is present. However, load changes, leakage in the system, or malfunctioning dampers can increase oxygen concentrations to levels suitable for explosions.

The experiments show that the size relationship of pulverizer, classifiers, crushers, and fans to coal pipes is crucial in explosion origin and growth. The relative sizes determine whether or not a detonation can occur as well as the magnitude of the resultant forces. Detonation evolution requires a change in volume and must originate in a pulverizer system component other than a coal pipe. While a fire is located in a coal pipe, it cannot trigger a detonation. However, if the fire moves and enters a piece of equipment of different size and venting characteristics, then the probability of an explosion increases. The relocation of a fire to other components of pulverizer systems such as the classifier. Crusher. Fan, or pulverizer can create a detonation.

The objective of this project is the assessment of pulverizer technology using the CMI/Terex RS-325 Roto-Mixer for the construction of contingency semi-prepared airfields for C-130 and C-17 military aircraft.

This machine is utilized as a Reclaimer/Stabilizer (commonly known as the Pulverizer machine) to provide soil stabilization through pulverization, and injection of water and polymer emulsions to the soil for the construction of roads and airfield pavement structures. This project is part of the Joint Rapid Airfield Construction (JRAC) program. JRAC has several technologies that are currently under investigation, and new research is being developed every day. The military engineers have to be able to meet the Soldier needs of rapidly selecting, stabilizing, and constructing contingency airfields in severe environments.

Pulverizers are used to smash materials into tiny shards or granules. Pulverizers can crush all types of items, including glass, aluminum, concrete, plastic, coal, rock, resin, tires, and medical waste.

A shredder pulverizer takes care of metal, tires, plastic, medical waste, and paper. A shredder pulverizer uses evenly spaced blades to cut material into strips. Some shredder pulverizers contain both vertically and horizontally spaced blades, which leave the processed material looking much like a form of confetti.

"In the work of the pulverizer, do not know what it (Breakers) not to stop there, then I have to guillotine it as soon as possible so as not to burn motor," saying this was a pulverizer plant operator Staff, he said that if you can not touch its temper, often caused by the crash phenomenon pulverizers, in the broken materials, we must pay attention to the attention of the material under the uniform, there is a hardness of the material According to the hardness of local materials, hardware, if so, can be combined with a bright process.

E-impact pulverizer of the main factors which affect the normal circumstances, E-breakers are the main factors in ras and to gnaw a few.

Pulverizer is a machinery that pulverize solid material into small pieces or fine powder.

Pulverizer and grinder called a total crushing machine. By the two nesting into the size of the particle size: Materials row size is greater than 3 millimeter cent of the total content of the row charge more than 50% of those who called the pulverizer; less than 3 millimeter cent of the total content of the row charge 50% More than those who were known as the grinder.

The most important and most easily wear parts of pulverizer is the hammer. Its shape, size, alignment methods, and so on, there be a great impact to pulverize efficiency and product quality.

According to the Chinese Academy of Agricultural Mechanization by 1.6mm, 3.0mm, 5.0mm, 6.25mm thickness of the four types of corn for the hammer to smash come to trial, 1.6mm than 6.25mm hammer to smash the effect of raising 45 percent more than 5mm to increase 25.4 percent. Thin with hammer to smash a high efficiency, but relative to shorten the useful life. Multi-thick hammer, smashing the target should be the size and type to another.

Although there were different types of pulverizer, but according to the application of force, the material has broken extrusion, bending, impact, shearing and grinding and other methods. In the pulverizer, the application of force is very complex, often several at the same time the existence of application of force, of course, there be only one or two of the main application of force in a pulverizer.

As the material is irregularly shaped particles, and the physical properties of different materials, the use of the different ways to pulverize, pulverize the use of mechanical materials imposed by external forces following several different ways:

The features of herbal pulverizer:

1, a high fineness: pulverize for the plant cell , with an average diameter of up to 5u fine.
