Hydraulic roller crusher adopts a pair of parallel and horizontally installed cylindrical roller to crush materials. The materials fall into the gap between the rollers from feeding mouth and get crushed. When there is something with too high hardness or uncrushable, the roller can back off automatically under the control of hydraulic cylinder and spring, protecting the crusher machine from being damaged.
The materials are crushed by the roller with opposite rotating direction. Compared with other crushers, roll crusher is more stable in rotating speed and crushing effect. The overcrushing phenomenon seldom happens. The most suitable rotary speed is dependent on the characteristics of the roll surface and the hardness and size of the materials. These features can be tested by experiment. The roller crusher should ensure high yield, low energy consumption and uniform products at the same time of light abrasion of the rollers. The bigger granularity materials have, the more slowly rollers should rotate. The speed of the grooved teeth roll crusher and toothed crusher should be slower than that of common roll crusher. It should have a higher speed when crushing soft or brittle materials and vice verse.
Crusher equipment is widely used in mining, metallurgy, construction materials, road construction, railway construction, water conservation and chemistry industry etc. the roller crusher has a special advantage in artificial sand making process. Although the one-time investment cost is higher than other crushing equipment, it has a higher productivity and sand rate obviously, which is out of reach for other sand making equipment.

Hammer crusher is the ideal equipment to handle the limestone. The hammer mill crusher can crush the large scale ore into the required size in one time. This hammer crusher machine can successfully replace the traditional two stage crushing process, which can simply the craft process and save the production cost. The hammering machine is independently researched by Henan Hongxing Mining Machinery Co., Ltd.. After the technology innovation, this machine has the advantages of high technology content, big crushing ratio, and high production ability. The hammer type crusher is popular in the large scale cement plant and sand stone plant.
At present, in order to prolong the service life of the hammerhead, foreign manufacturers adopts the martensitic high chromium cast steel as the material of the hammerhead, and it has already achieved good results. Now, Hongxing Machinery will briefly introduce you how to firmly fix the hammerhead when it is installed. And there are mainly three fixing means.
1. Pressing plate fixation. When we adopt this structural style, we must strictly control the manufacturing dimension of the hammerhead. But the wear-resistant material, like high manganese steel, is not easy to process, and it is hard to do the assembly work. In addition, the hammerhead is easy to loose if we use this method.
2. Wedge fixation. At present, most of the foreign manufacturers adopt this method. For it is convenient to replace and is of reliable work.
3. Screw fixation. When we use the screw to fix the hammerhead, the screw is exposed and easily to be destroyed.
The Hongxing Machinery will introduce the attention terms about the selection of hammer crusher:
1. The core parts of hammer crusher: rotor is the core parts of hammer crusher. Rotor is the heat of hammer crusher. It has the directly effect on the whole performance and service life of whole machine.
2. The service life of hammer crusher: The wear part of hammer crusher includes hammer head, main shaft, hammer shaft, hammer plate, grate plate, liner plate, etc.
3. The performance of hammer crusher: the performance of hammer crusher is reflected on its production ability and power consumption.
If you have any question about the hammer mill crusher, welcome to consult Hongxing Machinery: email@example.com.Since its inception, has been widely recognized and trusted by customers, which creates enormous economic benefit for enterprises.

Screw washing machine is the professional and high-efficient washing equipment for cleaning the artificial sand (including natural sand). Sand washing equipment adopts advanced technology, in combination with the practical situation of domestic sand industry developed efficient sand washing equipment. Sand washer is widely used for cleaning materials in the following industries: quarry, minerals, building materials, transportation, chemical industry, water conservation and hydropower, cement mixing station and so on.
The screw sand washer has height to clean, reasonable structure, large output, in the process of sand washing sand loss less, especially the transmission parts with water, sand isolation, so the failure rate is much lower than the current commonly used sand washing machine, is the best choice for domestic washing sand industry upgrading. Sand washing machine for sale price varies according to different models.
Tilted installation forms a sedimentation tank at the machine end. Screw head enters into tank. Screw be driven by motor and reducer and cleaning water enters into sedimentation tank from the bottom. Thus it completes the three functions of washing, dewatering, classifying. Sand enters into tank and grinds under the rotating screw effect. The impurities covered on the sand be removed and sand moisture layer be damaged for easy dewatering. The cleaning water injected from machine bottom forms a flow and it sends the fine particles and impurities to the surface, then finally be overflowed from weir. Heavy sand sinks into tank bottom and in the side of curved plate. Screw pushes sand up and forward. The excess water be removed. The removed water flows into tank through gutter from other side, while the dewatered sand be discharged from the tank top. The classification function is accomplished by overflowing fine particles. We can control it by adjusting weir height and screw speed.
