Specifications of HAIJIAN Roller Press
1) Saving Energy
2) High efficency
3) Stable performance

Roller press is new cement saving energy grinding equipment and developed in the middle of 1980s, can replace the system of ball mill competently or in partial, it is characterized by low consumption and lower noise, also reform the old factory. After selecting the equipment, may increase output of 40-100% for ball mill, fine material of 0.08mm covers 20-55%after material cake is pressed, less than 2mm covers 65-85%, Internal structure of fine material is filled with many small cracks, the grind ability is improved greatly. The roller surface is used heat built-up welding; It is convenient to maintain the abrasive layer.

cess requirements

(1)installation requirements: space requirement (size needed to retain around the roller press),about 2m at back and forth belong the roller axis, and each 2m belong the vertical direction, height: clear head is 2m from the top of frame.

(2)foundation requirements: Because the extrusion and crushing force is balanced in frame, so it only consider both vertical and level dynamic load factor. It can divide the foundation into two parts according to the weight and calculating the weight bearing of each by the ratio of equipment long. The vertical dynamic load factor can be considered of 1.8 while the level is 1.6.

(3)It shall equip magnetic separator and metal detector before feeding of roller press , and not allow the briquette into the grinder roll. The feeding material of less than 1mm shall no more than 25% to avoid moving of roller press.

(4)The integration water content of material shall no more than1.5%.

2. manufacturer’s standard and technical requirements

The equipment designing and manufacturing shall in line with existing state standards and ministerial standards, which including:

1,The roller shall be line with the occupation standard of JC/T845-1999.

2,The cutting machined part will use current technique requirement JB/ZQ4000.2-86.

3,The technical specifications of carbon structure steel is GB700-88.

4,Current technique requirement of welding is JB/ZQ4000.3-86

5,Rust prevention grade isGB8923-88.

6,The current technique of painting is JB/ZQ4000.10-86.

7, The current technique of packing is JB/ZQ4286-86.

8,engineering construction and acceptance specification of electric installation is GBJ232-82.

Roller body is hammered steel 45#, processing normalizing treatment,resurfacing welding wear resistant material on principle axis surface, first resurfacing welding using time is 8000 hours, overlaying welding using time is 3000 hours,

Stander structure is consist of upper,nether beam and left,right vertical shaft, and linked to a internal frame welding structure by loading bearing high strength bolts. It shall do integral relieving stress treatment after main frame welding.

Main axis bearing equips thermoelectric pair monitor bearing working temperature. Principle axis adopts midheaven hydro cooling.

Roller presser is painted evenly, with conformity hue, without flow phenomenon.
