Material moisture content on the impact of screening efficiency
The moisture content of materials, also known as the humidity or moisture. External moisture attached to the surface of the material particles have a significant impact on materials screening; moisture in the material cracks and moisture, combined with the material no effect on the screening process.
The basic structure and working principle of the squirrel-cage crusher
Traditional squirrel cage crusher from the base, the size of the squirrel cage wheel up and down the hood, pulleys and motor parts. The size of the squirrel cage wheel from the inside perimeter and twice hit stick. The hit stick riveted squirrel cage formed in the ring plate. Flange on the squirrel-cage key and squirrel axle assembly composed of two sets of empty sets with cage wheel. Have the squirrel cage axle mounted on an adapter sleeve Double row spherical roller bearings (self-aligning type), bearing through the bearing fixed in the seat, the other end of the shaft is equipped with pulleys, by Triangle tape and motor connection. Squirrel cage wheel at the top and sidewalls fitted with scraper cleaning machine in operation cast positive material. Squirrel cage wheel mounted on the hood, the hood is fixed to the base unit. Hood equipped with a chamber board at the top can be replaced after wear. Hood open valve, used to clean up the plot material glued to the machine housing. Valve is locked when the machine is running. Feed inlet on the side of the hood, the discharge port built-in adjustable feed position adjusting plate (cutting tongue). Discharge port open off the entrance and exit, the output of the crushed material from the transport machinery.

Improvement of cone crusher
Cone Crusher has over 20 years of production in our country's history. In order to improve the productive capacity and operation of medium and fine crushing cone Crusher reliability in recent years, according to production practices of its argument, structures had a greater improvement. Eliminates low spring pressure of the old series, was badly damaged and a series of mechanical problems. Crusher is more complete, and production capacity increased 20-30% of the Crusher.
Physical principle of crushed ore crushing machine
Material of the grinding process is a very complex process of size reduced, involving many factors and variables cannot be estimated. For example: the strength of the material, shape, size, hardness, toughness, moisture, density and uniformity, as well as external conditions-force method, type of stress, the stress intensity, speed, particle group crushing process of instantaneous stresses interaction force and its distribution. Strength, for example, in respect of the same kinds of ore, the difference is very obvious, even very wide. Strength depends primarily on the material size of cohesion. Cohesion is generally divided into two kinds: the first cohesion role inside the crystals of materials, that is, between the Crystal particle and the other cohesion between Crystal and crystal. Both cohesion of physical properties of the same, but is many times larger in value than the latter. Because of the complexity of crushing process still cannot be arrive at a unified, seamless, complete mathematical theory to describe the change.
Jaw Crusher nesting population determine the minimum width
Discharge gate size the width of a direct impact on productivity, and power consumption of the crusher wear of broken plate.
Selection of crushers hammer and terms of use
Hammer is a hammer crusher's main working parts. Hammer weight, shape and materials have a great impact on the productive capacity of the Crusher.
Rolling stone installation methods and considerations
Installation of roller type crushed stone base is cast iron frame, but there are also made of cast or rolled steel welded frame, due to the strength and stiffness of the frame requirements when installing base level should be maintained, and shall not use hammer hammering base. Support generally use rolling stone crusher rollers of train axle box bearing, so the installation, open a metres above sea level, on the in the axle box 30~45du inclined to install movable cover, so that when replacing the bearings easy. When installing the roller, carefully aligning centers, and as dynamic balance test, or roll in operation will "bounce", and soon the entire machine damage. Toothed rollers there are three: first with a hard carbon steel forged or metal tooth inlay and fixed on the rollers, such as fasten with a wedge, the COGS are unreliable, repair and demolition are very difficult.
Hammer crusher drive shaft, hammer description and performance analysis of hammer mill
Hammer Crusher drive shaft is the mainstay of hammer crusher, commonly known as the principal axis, rotation of the shaft does not stop, and top it with some heavier components, such as flywheels, hammer, and so on, so load on the drive shaft is large. So the hammer mill to elect 40th steel drive shaft material. In the rural areas at present steel, it is hard to find, steel, he can be used instead. Smooth when processing in the crusher drive shaft, shaft surface must not be allowed a rough feeling. Driven shaft spinning at brought to contact their parts on top of a lot of wear and tear. When open seating on the shaft should be in strict accordance with the size, processing should be special care. In order to better fixed disks (partitions) and position of the sleeve on the shaft, at the outer ends of crushing equipment drive shaft that is the furthest two divisions outside of inverse Shun threads in two different directions, processing should be picking up on this.
