Green Roll Crusher Adapt to Environmental Idea

After we analyze its working principle, we will find that it is just suitable for cement production technology. This material in powder form can be changed from plasticity paste to hard stone-like body and can become a total cemented granular material through physical and chemical processes after being mixed with water. So it is a good mineral binder. It can be not only hardened in the air, but also better hardened in the water in which it will maintain and develop strength. So it is kind of cementitious material which will be of stronger hardness in water. Ball mill is used for cement grinding. In the concrete mining, you need to choose suitable grinding mill and impact crusher.
The clinker roll crusher is a primary component to drive the grate motor, it is mainly composed of cylinder body, roller, speed measuring device and the transmission. The roller crusher has several rollers, each is installed with a roller shell. And it is easy to extract each roller to change the roller shell. Furthermore, every roller is drived by a helical gear motors with a planetary reducer.
Clinkers fall from the grate bed onto the roll crusher, the fine particles fall into the discharge chute between the rollers, while the larger blocks are crushed by the roller. A roll crusher has several rollers, the adjacent two rotate against with each other and the relative rotating couple forms a crushing unit, several crushing unite like this complete the crushing work. The rotation direction of the roller closest to the discharge port is clockwise while the farthest one is anticlockwise, those two rollers’ rotation is irreversible. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like china dryer, Henan Hongxing is always doing the best in products and service.circular vibrating screen: http://www.china-hxjq.com/p21.html
The drive current of each roller is set with a limit, when encountering extreme hard or large materials, the roller will reverse automatically when the current overloads to protect the roller shell from getting damaged. The reverse operation is as follows:
1. Under normal conditions, the roller stops with its paired roller on the outside, performing the following actions in the middle of them.
2. The action roller stops for t1 then reverses for t2 to get stopped.
3. For another t1, this pair of rollers re-starts and rotates in normal working status.
4. It will send out an alarming signal when the times of the reverse operation surpass n in t3.
The above procedures are controlled automatically via the program. When it alarms, the maintenance staff should find the problems through the manhole and the observation hole. Then the roll crusher can be re-started after the troubleshooting is completed.
If the feeding materials are not uniformly distributed on the full length of the roller, the roll surface will be quickly worn and each point is worn in different level. For this reason, annular groove will be formed so that the normal crushing work is damaged and the grain sizes of crushed products are not uniform. Therefore, apart from the roller crusher that is used for coarse crushing, the medium roller crusher and fine roller crusher are equipped with feeding machine to ensure the feeding continuous and homogeneous. What's more, the length of feeding machine is same with the roll length so that the feeding materials can be uniformly distributed along the direction of roller length.
