Limestone Micro Powder Grinder

raymond grinding mill is suitable for processing various non-flammable and non-explosive mineral materials with Moh’s hardness less than 9.3 and humidity less than 6%, it is widely used in the fields of metallurgy, construction, chemical industry, mining, highway construction etc,. The granularity of the finished powder size can be adjusted between 50 and 325 mesh (315-45 micron). Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore, carborundum, bauxite, rock phosphate, coal and other materials, total about 400 kinds of materials.

Limestone Micro Powder Grinder，limestone powder production line: main unit, analyzer, fan, dischargeing cyclone separator, powder cyclone separator and air duct. Among them, the main unit consists of frame, blow shell, shovel, grinding roller and grinding ring.

Limestone Micro Powder Grinder,Limestone Grinding Process

Firstly, big limestone block is crushed by jaw crusher to the size required, and therefore the crushed limestone is elevated right into a hopper. Then the limestone is transported with the electro-magnetic vibrating feeder, evenly and continuously to the grinding chamber for powder-processing. The rollers oscillate outward to press the ring as a result of centrifugal force and also the shovel scoops up the materials, send towards the middle between ring and roller to perform the grind. Following this, the floor limestone powder is carried by the air from the blower to the separator for screening. The fine powers are blow to the cyclone collector and so are poured out with the output-powder valve since the final products and the rough stuff after the screening is going to be recycled into the grinding chamber for regrinding.

Limestone Micro Powder Grinder,The limestone processing equipment

The limestone production line is widely used for limestone and cement production. There are mainly two sets of production line. One line produces calcium carbonate without roasting but direct grinding. The other line mainly uses carbonizatinmethod , also called high temperature firing method, which is roasted by rotary kiln. The limestone is mixed with anthracite according to a certain proportion then through high-temperature calcination, water digestion, carbon dioxide carbonization, centrifugal dehydration, drying, cooling, crushing and sieving, the end products--light Calcium Carbonate will be got. This is the light calcium carbonate production line.

Benefit of Limestone Micro Powder Grinder

It has the similar working principle as Raymond mill, but its grinding device is fixed with 1000-1500kg pressure springs. When the machine works the grinding roller , which under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of Raymond mill given an identical condition and its capacity increase 20% to 30%; When the grinding roller and grinding ring, stable capacity and fineness are guaranteed.

1. High pressure spring design.

The grinding device of the main unit is fixed with 1000-1500kg pressure springs. When the machine works the grinding roller , which under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rollingpressureis 1.2 times higher than that of Raymond mill given an identical condition and its capacity increase 20% to 30%; When the grinding roller and grinding ring, stable capacity and fineness are guaranteed.

2. Smoothly vibration reduce design

The main unit and up side classifier are connected by spring,and sealed with soft belt,which reduce the noise and avoid sympathetic vibration,reduce the vibration of machine vastly.

3. Convenient vane adjust design.

Gap between vane end and shell are the main factor of product fineness ,this is a patent of this mill .

4.The machine has a strong material applicability , which suits for many kinds of material whose Moh’s hardness is less than 9.3.

5. Grinding device adopts superimposed multistage seal, sealed performance is good.
