Wuhan Handern crushing and grinding
Through the relative movement of the object to shear, impact to 10 medical scale, Qu crack, rub the role of the museum to make the object broken, this is the prototype of crushing equipment. There are many types of equipment for crushing and coarse slamming. The following is a brief introduction of several commonly used ship types (grinding to a fineness of less than 50m). PET sheet www.handern.com(1) The roller crusher is composed of a number of halogen like materials, and the two rollers rotate inward to compress and crush the materials. The diameter is 0-20 rpm, 400 ~ 8 ~ 90r / min, which is used for coarse crushing.
(2) There are a number of hanging hammers on the high rotating shaft of the hammer type medical crusher. There is a convex tooth scale installed in the smooth wall of the crushing chamber, and the materials are broken by the hammer under the action of centrifugal force. It is used for coarse crushing of brittle materials. The crushed materials can pass through a box net with a diameter of 1 or 7mm. If H800 is used, it can be crushed to several millimeters to several microns at a high speed of 800 ~ 200R / min per day.
(3) The material of the impeller impact type powder ballast machine is crushed by impact, friction and compression between the high-speed rotating impeller of 1200 ~ 2500r / min and the Tang Bu Xu installed on the shell. It can crush tough plastics with poor heat resistance, but it is not suitable for crushing fibrous materials.
(4) There are two circles of impact columns on the high-speed rotating turntable of the disc crusher. There are teeth on the fixed plate. The materials are crushed by impact and shear under the action of centrifugal force.
(5) The rotary shaft and the shell of the rotary shear are equipped with a cutting knife, so that the materials are sheared, impacted, shrunk, torn and crushed. The particle size is controlled by screen.
(6) The melt crusher melts and grinds the material at 160 ~ 00C, and can put in 10x65450x430mm bulk material. PET sheet www.handern.com
(7) the material crushing part of wet material handling machine is composed of time piece, cutter wheel, ring and grid shed, and the material is opened in a smooth street. It is allowed to collect soft and current materials such as powder, PRC, PA and empty materials, and control the fine particles above 5 sea level or even below 1 pm.
(8) Jet mill uses ultrasonic to jet powder
The particle size is about 1 um.
(9) The low temperature crushing device makes the material brittle by the low temperature of liquid nitrogen, and then grinds the material into less than 20 pieces. It is used for crushing of thermal engineering plastics or secondary plastics. The purpose of reinforcement analysis is to remove large particles and mechanical impurities, so as to meet the requirements of fineness and uniformity, which is conducive to the integration and separation uniformity. Fineness refers to the number of millimetres of grain diameter in the lining period, which is usually characterized by the number of mesh days. Evenness refers to the fine powder with the diameter between particles, i.e. 1-down door, 2-down knife rest, 3-down fixed knife, to distribution 4 One turret, 5 one piece, 6 one chest frame, 7-rotor, 18 crushing chamber, 9-upper strike fixed knife, 10 upper strike turret.
