This machine is mainly used for the mixing of coated sand. Work organization USES scraper and the rotor relative motion, make the material in the machine dish can mix in a very short time, make the sand coated, sand are of good quality and high efficiency, and the sand block has a good ability of fast break.

The main structure

The transmission system includes main motor, rotor motor, narrow V belt and reducer. The main motor and rotor motor are mounted on the bracket and are connected with the pulley of the reducer by the narrow v-belt of the first class and then the deceleration of the first cylindrical gear. The main motor drives the hollow shaft, which is driven by the hollow shaft. The rotor motor drives the rotor shaft, which drives the relative motion of the rotor and the scraper. The reducer is fixed under the chassis of the mixer, and a magnetic oil plug is installed in the box to collect the iron scrap in the lubricating oil to reduce the wear of gear and bearing and prolong its service life.

Work organization

The working mechanism is composed of scraper and rotor. The two scraping plates mounted on the column sleeve and the rotor mounted on the rotor are driven by the reducer output shaft to generate relative motion. Two bottom scraping plates are welded with carbide knife blocks to reduce wear.

Lubrication system

Because only partial bearings are immersed in lubricating oil in the reducer, the machine adopts forced lubrication. The lubricating system consists of the auxiliary fuel tank and the motor, gear pump, small oil cylinder, travel switch and reducer on the auxiliary fuel tank. The auxiliary fuel tank is connected to the reducer by a connecting device. When the motor is started, the lubricating oil in the auxiliary tank is passed through the filter, and the piston of the small oil cylinder is pressed by the oil pump, so that the travel switch is switched on and the main motor can be started. The lubricating oil is lubricated by distributing body and pipeline. Failure occurs when the lubrication system, oil pressure is reduced, the piston under the action of the spring reset, travel switch off contact, signal control console is in failure, the main motor power, the machine stopped running.

(1) the body

It consists of a ring, a leg, a backing plate, a chassis and a bracket. The ring and bottom lining are provided with water interlayer, which is cooled by circulating water.

(2) discharge door

There are two types of discharge door, one is manual flip side discharge, the other is pneumatic side discharge, the user can choose according to demand.

A) the machine has a base, which is generally installed on the reinforced concrete foundation and can be installed on the steel frame. If it is installed on the steel frame, it must be guaranteed to have sufficient strength and rigidity.

B) after the machine is installed, check the bottom level of the chassis, and the allowance is 0.5/1000.

C) prior to the operation of the experiment, the relevant personnel must have a comprehensive understanding of the specifications and the performance of the machine.

D) before starting the machine, the machine must be cleaned thoroughly and the machine should be thoroughly checked, whether there is any loosening of the fastening screws everywhere.

E) add sufficient lubricating oil and grease as required.

F) to start the machine, continuous operation for 2 hours, during this period should be constantly check whether there is loose phenomenon everywhere, whether there is abnormal noise and vibration reducer, lubricating system is normal, then load tests are carried out. Coated sand production line.
