Sizer Crusher machine is a type of double roll crusher, the roll surface shape can be divided into coarse fine-tooth roller, according to the size of the material needs to adjust the production, suitable for brittle and soft materials. Sizer Crusher is suitable for sinter, coal, cement, silicate, glass, ceramics and other industries, suitable for the crushing of brittle materials below medium hardness, mainly used for medium and fine crushing of ore.
Before the 1990s, the technology of tooth roller crusher can not strictly control the granularity of crushed products, crushed products over crushing amount, the impact load of the body is large, the broken teeth are easy to damage, the overall noise is large, the maintenance amount is large and other shortcomings.Such as to prevent the material in the miscellaneous wood, iron, waste rock, rock hard materials such as damage broken teeth, in single toothed roll crusher crushing plate bottom is equipped with tension spring, and in a sizer crusher a broken with compression spring on both ends of the roller, the purpose is when the bulk material or hard material fall Jing crushing cavity cannot be broken broken board or tooth roll force increase, thereby increasing compression spring asked the crushing cavity discharge gap, so that the discharge hard objects.Then borrow the restoring force of the spring to make the movable crushing plate or tooth roller back to the original position.This will not be able to strictly control the particle size of the broken products. With the accumulation of technical research and production experience of our HENAN Excellent Machinery Co.,Ltd, we developed the Sizer Crusher with the minimum crushing ratio.Our crusher can extend the service life of the tooth roller most effectively, we use alloy steel after special heat treatment, can very good improve the service life of tooth roller crusher.In addition, in order to reduce customers' downtime and losses as much as possible, we adopt integrated synchronous replacement of tooth rollers, which takes about 6-7 hours to complete.
Our Sizer Crusher because of the first-class technical design and strict quality control, high quality tooling and equipment and strict product quality inspection to effectively ensure that our products have high quality.Our products can be widely used in raw coal crushing, topsoil crushing, pebble crushing, as well as some sand and gravel treatment plants crushing work.
The installation
(1) The unit with vibration work of the Sizer Crusher pump should tighten all fasteners during installation and before test run, and should also be checked regularly during production operation and fastened at any time.
(2) Attention should be paid to the rotation direction of the machine (marked with rotating arrow on the pulley) is irreversible during installation.
(3) After the installation of the motor, it should be equipped with a transmission belt protective cover according to the installation situation.
(4) the gap between the counterattack plate and the plate hammer should be gradually reduced according to the work needs. After adjustment, the rotor should be rotated by hand to check whether there is impact.
After the adjustment is completed, the sleeve nut should be locked to prevent the nut loosening after the vibration of the counterattack plate and gradually falling into the collision with the plate hammer, resulting in accidents.
(5) Because the discharge port of sizer crusher is in the lower part, the installation height and how to cooperate with the feeding and discharging device should be well considered in the system design.
The maintenance (1) routine inspection should be made frequently during the operation of sizer crusher. When abnormal sound or bearing temperature is higher than 700C is found, the machine should be stopped for inspection immediately. After the fault is eliminated in time, the machine can continue to start.
(2) Feeding can be done after the machine is in normal operation. Feeding should be uniform and iron should be prevented from being mixed with hard objects.Before stopping the machine, the feeding must be stopped, and the machine will be cut off after the crushing of the materials in the machine.
(3) After the maintenance or adjustment of the discharge port, the rotor should be rotated by human first to confirm that there is no friction and sticking phenomenon between the rotor and other parts and that the rotor can rotate flexibly before starting the motor.
(4) Always check whether the seal of the bearing seat is good, the grease in the bearing seat should be filled once a month, and all the oil and felt should be cleaned and replaced every three months.
(5) when checking whether the fasteners are loose, should focus on checking the pressing plate screws of the pressing plate hammer on both sides of the rotor to prevent the loosening of the pressing plate, the two ends of the plate hammer exposed the rotor body, and the body collision, damage parts.
(6) In order to ensure the safety of operators and equipment, it is forbidden to repair, adjust and clean the machine during operation, and it is forbidden to open various small doors.
(7) when the particle size of the crushed product is too large, the machine should stop to check the wear of the plate hammer and prevent the rotor from being worn out.When the board hammer needs to be adjusted 180 0 for wear and tear, the weight of each board hammer should be equal and kept in balance to prevent vibration after starting the machine.
