To profit from Deep Rotor VSI Crusher
Deep Rotor VSI Crusher of Zhengzhou Kefid Machinery Co., LTD is of high efficiency. The low operating cost, high handling capacity, good final products shape, all of which together are in accordance with national high-speed material consumptions. In the following passage, the advantages of Deep Rotor VSI Crusher will be given by Zhengzhou Kefid Machinery Co., LTD.
First of all, let us talk about the easy-worn parts. Wear-resistant parts take a great part in the overall production cost, especially when the raw material is not limestone. When the raw material are basalt, granite, pebble, the maintenance cost is a big problem causing trouble. So, we research the prioritization sheme accordingly to solve this problem, prolong the life, reduce the production cost. and shorten the downtime to the maximum. Take DR VSI Crusher in detail. The form of the runner plate is well-matched with the way in which the materials run out, reducing the wearing of the inside of the machine; at the same time, the materials run out immediately and improve the working efficiency. In DR VSI Crusher, the hammer is a combined hammer including the main hammer and vice hammer, which prolongs the life of the hammer. In addition, the main hammer is made up of three pieces of small hammers. When a small part is worn, only the worn-part is needed to change. It is very easy and save many materials. In that case, we can save many production cost, and reduce the downtime greatly.
Additionally,the outlook of DR VSI Crusher is changed too. The cylindric cover replaces the structure of diamond shape, making the work more easily and quickly, reducing the cost. The shell of the machine is divided into two parts, which is one less than the traditional machine. This makes the examination and repaireing more easily, and shorten the downtime greatly.
Zhengzhou Kefid Machinery co.,LTD improves the Deep Rotor VSI Crusher, provides many technologies and prioritization scheme. We will always offer our machines and equipments with good serve.

How the effect of gyroscopic precession use to control main rotor disc to provide forward/rearward flight?
The movement of the cyclic pitch control in a two-bladed rotor system increases the angle of attack of one rotor blade with the result that a greater lifting force is applied at this point in the plane of rotation. This same control movement simultaneously decreases the angle of attack of the other blade a like amount, thus decreasing the lifting force applied at this point in the plane of rotation. The blade with the increased angle of attack tends to rise; the blade with the decreased angle of attack tends to lower. However, because of the gyroscopic precession property, the blades do not rise or lower to maximum deflection until a point approximately 90° later in the plane of rotation. the retreating blade angle of attack is increased and the advancing blade angle of attack is decreased resulting in a tipping forward of the tip-path plane, since maximum deflection takes place 90° later when the blades are at the rear and front respectively.
In a three-bladed rotor, the movement of the cyclic pitch control changes the angle of attack of each blade an appropriate amount so that the end result is the same - a tipping forward of the tip-path plane when the maximum change in angle of attack is made as each blade passes the same points at which the maximum increase and decrease for the two-bladed rotor. As each blade passes the 90° position on the left, the maximum increase in angle of attack occurs. As each blade passes the 90° position to the right, the maximum decrease in angle of attack occurs. Maximum deflection takes place 90° later - maximum upward deflection at the rear and maximum downward deflection at the front - and the tip-path plane tips forward. Rotor disc acts like a gyro. When a rotor blade pitch change is made, maximum reactions occurs approximately 90° later in the direction of rotation.
