Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: impurity removing pipe 1, feeding pipe 2, grinding chamber 3, fixed grinding disc 4, movable grinding disc 5, driving shaft 6, frame 7, motor 8, impurity removing plate 9, magnet 10 and clamping strip 11.

Example (b):

as can be seen from fig. 1, 2 and 3, a high consistency refiner comprises a frame 7, a refining chamber 3 is installed on the frame 7, a fixed grinding disc 4 and a movable grinding disc 5 are vertically installed in the refining chamber 3, the fixed grinding disc 4 and the movable grinding disc 5 are arranged oppositely, the fixed grinding disc 4 is fixedly installed in the refining chamber 3, and the movable grinding disc 5 is rotatably installed in the refining chamber 3. The movable grinding disc 5 is connected with a driving mechanism, the driving mechanism comprises a driving shaft 6 and a motor 8, the driving shaft 6 is fixedly connected between the output shafts of the movable grinding disc 5 and the motor 8, and the motor 8 is installed on the rack 7. A gap for grinding pulp is reserved between the fixed grinding disc 4 and the movable grinding disc 5, and a discharge hole (not shown in the figure) is formed in the bottom of the grinding chamber 3 and is aligned with the gap.
