Vibration mill introduction
In the late 1970s, China began to develop vibrating mills. After about 10 years of improvement, in 1990, it basically overcome the shortcomings of the original and was popularized and applied in production. In the past 10 years, the vibrating mill has been developed, the variety has increased, and the performance has been further improved. A vibration ball mill employed, alumina balls, steel bars and steel sections as a smaller cylindrical grinding media.
At present, many manufacturers in China produce vibrating mills, and their structures are generally the same. The vibrating mill produced by Henan Xinxiang Binhe Vibration Machinery No. 1 (hereinafter referred to as Xinxiang) is shown in Figure 1. It consists mainly of a frame, a cylinder, a vibrator, a transmission and a soundproof cover. The vibrating mill has two upper and lower cylinders, which are filled with grinding medium and material to be ground, and are driven by a motor through a flexible coupling. The vibration of the cylinder causes the medium and the material to be in a suspended state, and generates a small ejection impact and a grinding action to pulverize the material. Sometimes it is not necessary to load the medium, and only the material itself produces a grinding effect.
The grinding medium has a small size and a high filling rate, generally up to 60%, so that a more effective grinding action can be exerted on the material. Vibrating mill can be employed in a dry or wet open operations, can be widely used in the metallurgical, mining, building materials, refractory, glass and ceramics industries, various materials was pulverized, especially for feldspar, graphite, and manganese Grinding of magnesium ore. However, since the volume of the polishing cylinder is generally small, the amount of processing is not large.
1. 2GDZM vibration mill Xinxiang produces a variety of vibration mills (Table 1), with high output, low energy consumption, light weight, low noise, small floor space, uniform product size, simple operation and easy maintenance. The advantages of easy replacement of the liner and medium, and simple process; especially in recent years, the outdoor water jacket of the bearing has been increased, and the bearing life has been prolonged; the rubber liner and the alumina medium can basically achieve the iron- free wear and the iron powder. Grinding work is very suitable.
Model meaning description 2GDZM-100: 2 - double cylinder, (} - high efficiency, D - low energy consumption, Z - vibration, M - mill, 100 - mill volume (L).
The dimensions of the 2GDZM-100~800 vibrating mill are shown in Figure 1 and Table 2. The mounting base dimensions are shown in Figures 2~3 and Table 3, respectively. The vibrating mill needs to be cooled by water during operation, and the user must bring his own pool and water pump.
2. Multi-purpose vibration grinding machine The 2MZ series multi-purpose vibration grinding machine developed and produced by Beijing Hongding Machinery Co., Ltd. (hereinafter referred to as Beijing Hongding) is the equipment for processing large-scale ultra-fine powder in China. The product technology is at the leading level in the country and advanced in foreign countries. It has the characteristics of high efficiency, energy saving, ultra-fine, low noise and multi-purpose. The company can provide consulting, various process design and auxiliary equipment and equipment services for customers.
The vibrating mill is a multi-purpose large-scale vibration grinding equipment, which can be used for dry and wet grinding, closed circuit and open circuit work, and can be used together with other milling equipment, mainly used in chemical, ceramic, fireproof, non-metallic minerals, finely ground powder metallurgy, slag, cement, coal ash powder and ultrafine grinding material. The technical parameters are shown in Table 4.
3. 2MGZ high-efficiency vibrating mill The 2MGZ high-efficiency vibrating mill produced by Wuhuan Mine is a new type of fine crushing and grinding equipment . Applicable to the production of glass raw materials, machine sand production, fine clinker of cement clinker, crushing of steel clinker, fine crushing of furnace, crushing of hydrous coke, crushing of special hard materials to 1~10mm, powder metallurgy, mining, building materials, refractory materials, Grinding operations in the chemical industry. The two mill barrels are arranged in series during fine grinding and in parallel in coarse grinding (ie, fine crushing).
The characteristics of this mill are as follows: 1 steel consumption is extremely low, only 1/3 of other conventional equipment; 2 in the grinding operation, the grinding particle size can reach 40mm, the product granularity can be adjusted between 5mm~325 mesh, with grading After the equipment , the product size can reach 800 mesh; 3 product shape is multi-angled sphere; 4 the same mill can be dry or wet grinding, and can realize vacuum grinding; 5 vibration spring is special rubber spring, start and stop stable, noise Lower.
This mill passed the ministerial appraisal in 1992 and obtained the national patent. The main technical parameters are listed in Table 5.
4. Vibrating rod mill MGZ-1 high-efficiency vibrating rod mill is an advanced high-efficiency vibrating rod mill jointly produced by Xi'an Metallurgy College and Xinxiang Xinxin Mine Vibration Equipment Co., Ltd. (hereinafter referred to as the new mine). .
The mill has compact structure, small volume, light weight, large crushing ratio, energy saving, saving raw materials, saving space, high output, remarkable economic benefit, convenient transportation and installation and operation and maintenance.
The rough grinding mill is widely used in various industrial sectors of different materials metallurgy, chemicals, building materials, phosphate fertilizer, potash feldspar, coal, medicine, mineral processing, metals, fine grinding and ultrafine grinding operations. The technical parameters are listed in Table 6.
5. ZMF type internal vibration grinding mill ZMF series internal vibration grinding mill produced by Qingdao Mining Equipment Factory (hereinafter referred to as Qing Mine) is a micro-scale fine powder crushing equipment with good energy-saving effect and high grinding efficiency, especially in minerals. The application of ultra-fine deep processing has attracted the attention of domestic and foreign counterparts. It can quickly obtain finer products with less energy, which can complete grinding and grading at one time, and qualified materials will be discharged as soon as possible. Unqualified materials will continue to be ground and reduced. After smashing and unnecessary energy consumption, the raw materials entering the mill are qualified fine powder, and the process system is simple, which makes the vibration grinding technology to a new level.
The working principle of the vibrating mill is shown in Fig. 4, which is mainly ground by the horizontal circular motion and the vertical tumbling motion of the material.
The advantages of the vibration mill are: 1 high pulverization efficiency, 5000 times of impact of the medium is 5,000 times that of the ordinary ball mill , and the energy utilization rate is high; 2 the filling rate can reach 80% to 90%, and the ordinary ball mill is only 30% to 40%; 3 Less impurities, less effect between the media, no excessive impact, less wear on the liner, ceramic liner and medium to avoid iron pollution; 4 media movement is a unique ternary rotary motion, with Good grinding method; 5 grinding and grading integration, reducing energy consumption; 6 working under negative pressure, no dust spilling.

Trench cutters are a new drive concept that transmits an enormously high torque to the cutting tooth with relatively low drive power. The familiar similar trench cutter wheels, which almost all come from America, are designed as self-propelled machines with the same drive concept in such a way that the cutter wheel is always driven from the centre via the gearbox, so only relatively low cutting depths can be achieved.
