1. General introduction

   JM series colloid grinder is a new equipment of processing for wet-type ultramicron, suited for homogeneity, emulsify and smash for all kinds of lactescence in the industries of food (jam, juice, soymilk, dairy products and beverage), pharmacy (syrup, nutrient solution, Chinese patent medicine and solid drug), daily use of chemical industry (toothpaste, cosmetic and detergent), chemical industry (dye, pigment, coating, grease and petroleum catalyst) and producing of flotation and emulsion explosive.

2. Structure

   JM series colloid grinder is categorized with vertical type, horizontal type and other types. It is mainly composed with grinding head, base transmission and electromotor. Parts in contact with material all adopt high quality stainless steel. Static abrasive disc is the machine key components, according to be processed materials of different nature, abrasive disc gear-shape differ, but different material are chosen for stainless steel tool manufacture. Motor is made according to the need of colloid mill special design, and the motor flange cover is installed with mounted flush dish for waterproof and prevention of leakage. Please refer to the structure chart.

The basic operating principle is cutting, grinding and high-speed stirring. Grinding depends on the relative motion of two tooth profiles. One revolves with high speed, the other is static. By cutting and grinding of the material, as well as high frequency vibration and high speed vortex, the material is efficiently dispersed, melted, grinded and uniformed.

Ⅳ . Considerations for Operation

•  Connecting the feeding tube, discharging mouth or discharging circular tube. Graft in cooling water pipe and leakage pipe.

•  Install the electric starter, ammeter and indicator lights. When the power is connected, turn on operation to see the steering direction. The direction from the charging hole is clockwise.

•  Adjust the gap of abrasive disc. Unscrew two handles unscrew (anti clockwise twist) then adjust rings clockwise. Use one hand to stretch into base square mouth roll inside motor wind leaf, then when turning adjust ring felt with a little friction and stop immediately. Reversely adjust ring again to make abrasive disc gap to the aimed digital. Usually when meeting the processing requirements of fineness of materials, make it possible to enlarge abrasive disc gap slightly. So it can make abrasive disc long use life. Then clockwise tightening handle will lock the adjustable ring and make abrasive disc gap fixed.

•  Clean thoroughly and disinfect.

•  Connect the cooling water. After turning on the colloid grinder, put the material into the grinder to process. The revolving should not be more than 15 seconds.

•  Quartz, scattered glass and metal fillings are not allowed into the material; otherwise they will damage the grind and blade.

•  Pay attention to the load of motor. Reduce the material if overloaded.

•  The colloid grind belongs to high precision machinery. The gap of abrasive disc is narrow with high speed revolve. The operator shall be strict on position and perform according to the rules. When stopped with breakdown, restart after debugging.

•  After the usage of colloid grind, clean thoroughly the residue inside the machine to prevent leakage caused by mechanical seal.

Ⅴ . Installation

JM series colloid grind can be operated stably with slight shock. It can be set on flat ground or concrete according to the requirements of production and utilization. See the following table:

Ⅵ . Maintenance

•  This machine is high precision optical machinery with rapid revolve and linear velocity 20 m /s. While the abrasive disc is narrow. Use dial indicator after examine and repair to revise axiality between the shell appearance and principal axis with error ≤ 0.5mm .

•  When repairing, during unpacking and installation, knocking with hammer is not allowed but to use wooden mallet or knocking lightly above wood brick to avoid damage of components. There are specific tool for dismantling of abrasive disc.

•  The machine is sealed with static seal and motive seal. Motive seal adopts mechanical seal and combined seal. Static seal uses O-type ring. Use red copper to seal when frightening. Seal of socket shall choose teflon belt. Mechanical seal shall choose pinkfusedalumina ceram and change broken one immediately. Grind if scratch is found on flat board or plate glass with carbonized silicon scrub.

•  Maintenance shall be preceded according to the material.

•  Please refer to the operating manual for maintenance of motor.

•  The components are mostly international standard parts which can be purchased around the nation. The list of components can be referred from the container loading list.
