The main features of gangue crusher: gangue crusher, no mesh grate at the end, a variety of wet material can be crushed, unbonded clogging, but were down two double rotor hammer crushing, crushing ratio, the material particle size of not more than 3mm to meet the production standard bricks. hollow brick requirements. Hydraulic electric start the case, only one person can easily open and close, not only lightweight, fast and safe, reliable, easy to maintain. Energy-saving equipment, excellent quality, easy to maintain, less wearing parts, etc., small work area, use of a wide range of fixity strong, fixed and mobile operations can be easy to move. Composition Structure: This machine consists of frame, rotor, liner, hammer and other component parts, sheaves transmission, material both high-speed rotation of the rotor material impact hammer driven role in front of the broken plate is broken. Frame is divided into two parts, the upper body and lower body, the chamber is equipped with an internal engine wear and protective liner to protect the body's internal wear and deformation of the rotor shaft of the rotor there is a difference, in the middle disc, the disc ends, the hammer shaft , hammer and other component parts. Note: 1, while the gangue mill equipment assembly or replace the hammer, must maintain a balance of the rotor, the total weight of each row hammer hammer shaft should correspond to the total weight of the hammer hammer axis equal to the total deviation of not more than 100g, and gangue mill equipment single hammer weight deviation not greater than +/- 0.5 kg. 2, long-term use of coal waste grinder, for replacement shaft, bearings, housings and other components, the assembly must be maintained through the heart of a large shaft assembly, calibration housings, hand drive shaft turn idle ease, square can start the test, pay attention to the bearing temperature conditions. 3, after the impact hammer mill part gangue side wear, use the other side can be swapped. 4, after both sides gangue hammer mill equipment are worn, four adjustable hammer shaft on the rotor disk installation location (outward shift eye), continue to use .. 5, Coal mill during operation as a result of material factors, material into the discharge port after unloading the poor (the case is not a knot under the wall) is recommended to be superior in each group gangue crusher hammer to remove a cross, try again. 6, Coal mill in the course of their work as a result of material factors, lower-level terminal cinder mill discharge spout poor, crushed fine material in the cavity can not be repeated escape, so the lower the load is too large, it is recommended that direction of the bottom piece spout abdominal lining removed, the spout to expand from 50 to 80 cm, so that the material smoothly, reducing the lower load. 7, coal crushing grate at the end did not solve the problem of wet material sticking, but the hammer wear between the liner and the gap is too large, the corresponding size will be thicker, recommendation 8, the hammer shaft by two bonnet cinder mill plate hexagon screws on the side of the rotor disk, such as badly worn cover, which should be replaced, such as severe wear affects the hexagon screw, will cause difficulties to remove the hammer axis. Five advantages of a Coal mill, coal mill down double lumen internal hammer collision crushed stone material crushing lower fineness. 2. Coal mill special production process hammer hammer hardness strengthen increase 2-3 times faster than ordinary life hammer. 3. Coal mill special two-way technology transfer gap can control the fineness of the crushed material to enhance the use of cost-hammer. 4. Coal mill centralized grease lubrication system reform focus to the oil nozzle configuration step of operating multiple distribution pump oil. 5, gangue mill equipment running smoothly without major noise increased rotational inertia to overcome the resistance movement can save more than 20%
