Swivel type lead-bronze bushed trunnion bearings are generally furnished on large diameter ball Mills. The bearing swivels are of Meehanite metal spherically turned outside and bored and faced inside to receive the removable bushing. The bushing is bored and scraped to fit the mill trunnion. The bushing is provided with end flanges thus assuring that the trunnion flanges run against a bronze face.
On smaller mills rigid or swivel type bearings support the mill trunnions. The lower half of such bearings are lined with bronze or a special mill babbitt which is peened in place and bored to fit the trunnion.
In all cases a low bearing pressure is maintained to assure freedom from overheating, long life and minimum maintenance. They are designed to provide support to the mill proper, its media and pulp load.
Trunnion bearings are generally supplied with seals for use with a circulating oil lubrication system. They can be designed to accommodate block grease or oil with wool waste.
For special applications trunnion bushings can be furnished constructed of Micarta to allow water lubrication or oil lubrication.
In many dry grinding applications, or where heat is developed, the trunnion bearings can be furnished for water cooling. This system carries away the excess heat transmitted through bearings and protects them.

Cone crusher mainly consists of frame, drive shaft, eccentric sleeve, spherical bearing, broken
It consists of a broken cone, adjusting device, adjusting sleeve, spring and cutting port.
During the working process of the cone crusher, the motor drives the eccentric sleeve to rotate by the transmission device, and the moving cone rotates under the eccentric bushing. The section of the moving cone close to the static cone becomes the crushing cavity, and the material is subjected to the moving cone and The static cone is crushed by multiple extrusions and impacts. When the moving cone leaves the section, the material that has been broken to the required particle size falls under its own gravity and is discharged from the bottom of the cone.
Pay attention when working
1, the feed size ratio is appropriate
2. Automatic control device;
3, the crusher discharge to pass
4. Correctly select the crushing chamber for the broken material.
5. Evenly distributed in the 360° range of the crushing chamber
6. The specifications of the conveyor belt are compatible with the maximum output capacity of the crusher;
7. Appropriate selection of sieve specifications for pre-screening and closed-screen screening.
The jaw crusher is commonly known as smashed, also known as the tiger's mouth. The crushing chamber is composed of two jaws, which are composed of two jaws, which simulate the two movements of the animal to complete the crushing operation of the material crushing operation. It is widely used in the crushing of various ores and bulk materials in industries such as mining, building materials, roads, railways, water conservancy and chemical industry. The highest compressive strength of the material to be crushed is 320 MPa.
Jaw crushers are mainly used as coarse crushers and medium crushers in mining, building materials and infrastructure. According to the width of the feed port, it is divided into three types: large, medium and small. The feed port width is larger than 600MM for large machines. The feed port width is 300-600MM for medium-sized machines. The feed port width is less than 300mm for small-sized machines. machine. The jaw crusher is simple in structure, easy to manufacture and reliable in operation.
The working part of the jaw crusher is two jaws, one is a fixed jaw (fixed), the vertical (or the upper end is slightly inclined) fixed on the front wall of the body, and the other is the movable jaw (moving), the position Tilting, forming a large and small crushing cavity (working cavity) with the fixed jaw. The movable jaws periodically reciprocate against the fixed jaws, sometimes separated and sometimes close. When separated, the material enters the crushing chamber, and the finished product is discharged from the lower portion; when close, the material contained between the two jaws is crushed by bending, bending and splitting.
The jaw crusher can be divided into a simple swing jaw crusher (simplified pendulum jaw crusher) according to the different swinging modes of the movable jaw. There are three kinds of complex swing jaw crusher (complex pendulum jaw crusher) and integrated swing jaw crusher.

Gyratory crusher models: Ð?KÐ?-900, Ð?KÐ?-1200, Ð?KÐ?-1750, Ð?KÐ?-2200,
The rotary crusher is a vertical composite crusher, also known as a composite crusher, which is a machine for crushing production lines and sand production lines.
The gyratory crusher and the funnel cone crusher are all one type of cone crusher. The gyratory crusher is a coarse crusher. Compared with the jaw crusher, the crushing process is continuous along the circular crushing cavity, so the productivity is high and the power consumption is low. Work is smooth. Suitable for crushing sheet materials. Visible from the finished product size distribution curve. In the particle size composition of the finished product, the material size exceeding the width of the discharge port is smaller than that of the jaw crusher, and the number is small, and the particle size is relatively uniform. In addition, the original material can be poured directly from the transport into the feed port without the need for a feeder.
Advantages:
The structure is simple and reasonable, and the running cost is low. Using the stone stone principle, the wear is small.
High breaking rate and energy saving.
With fine crushing and coarse grinding function.
It is affected by the moisture content of the material and the moisture content can reach 8%.
More working noise is less than 75 decibels (db level), and dust pollution is less.
Suitable for crushing medium and hard materials.
The product is in the form of a cube with a high bulk density and minimal iron contamination.
Impeller self-lining wear and maintenance, easy maintenance
